# Built-in Functions
|
||||
|
||||
Smarty comes with several built-in functions. These built-in functions
|
||||
are the integral part of the smarty template engine. They are compiled
|
||||
into corresponding inline PHP code for maximum performance.
|
||||
|
||||
You cannot create your own [custom functions](../language-custom-functions/index.md) with the same name; and you
|
||||
should not need to modify the built-in functions.
|
||||
|
||||
A few of these functions have an `assign` attribute which collects the
|
||||
result the function to a named template variable instead of being
|
||||
output; much like the [`{assign}`](language-function-assign.md) function.
|
||||
|
||||

|
||||

# {append}
|
||||
|
||||
`{append}` is used for creating or appending template variable arrays
|
||||
**during the execution of a template**.
|
||||
|
||||
## Attributes
|
||||
|
||||
| Attribute | Required | Description |
|
||||
|-----------|------------|----------------------------------------------------------------------------------------------------|
|
||||
| var | | The name of the variable being assigned |
|
||||
| value | | The value being assigned |
|
||||
| index | (optional) | The index for the new array element. If not specified the value is append to the end of the array. |
|
||||
| scope | (optional) | The scope of the assigned variable: parent, root or global. Defaults to local if omitted. |
|
||||
|
||||
## Option Flags
|
||||
|
||||
| Name | Description |
|
||||
|---------|-----------------------------------------------------|
|
||||
| nocache | Assigns the variable with the 'nocache' attribute |
|
||||
|
||||
> **Note**
|
||||
>
|
||||
> Assignment of variables in-template is essentially placing application
|
||||
> logic into the presentation that may be better handled in PHP. Use at
|
||||
> your own discretion.
|
||||
|
||||
## Examples
|
||||
|
||||
```smarty
|
||||
{append var='name' value='Bob' index='first'}
|
||||
{append var='name' value='Meyer' index='last'}
|
||||
// or
|
||||
{append 'name' 'Bob' index='first'} {* short-hand *}
|
||||
{append 'name' 'Meyer' index='last'} {* short-hand *}
|
||||
|
||||
The first name is {$name.first}.<br>
|
||||
The last name is {$name.last}.
|
||||
```
|
||||
|
||||
The above example will output:
|
||||
|
||||
|
||||
The first name is Bob.
|
||||
The last name is Meyer.

||||
|
||||
## Examples
|
||||
|
||||
```smarty
|
||||
{assign var="name" value="Bob"} {* or *}
|
||||
{assign "name" "Bob"} {* short-hand, or *}
|
||||
{$name='Bob'}
|
||||
|
||||
The value of $name is {$name}.
|
||||
```
|
||||
|
||||
|
||||
The above example will output:
|
||||
|
||||
```
|
||||
The value of $name is Bob.
|
||||
```
|
||||
|
||||
|
||||
```smarty
|
||||
{assign var="name" value="Bob" nocache} {* or *}
|
||||
{assign "name" "Bob" nocache} {* short-hand, or *}
|
||||
{$name='Bob' nocache}
|
||||
|
||||
The value of $name is {$name}.
|
||||
```
|
||||
The above example will output:
|
||||
```
|
||||
The value of $name is Bob.
|
||||
```
|
||||
|
||||
|
||||
```smarty
|
||||
{assign var=running_total value=$running_total+$some_array[$row].some_value} {* or *}
|
||||
{$running_total=$running_total+$some_array[row].some_value}
|
||||
```
|
||||
|
||||
Variables assigned in the included template will be seen in the
|
||||
including template.
|
||||
|
||||
```smarty
|
||||
{include file="sub_template.tpl"}
|
||||
|
||||
{* display variable assigned in sub_template *}
|
||||
{$foo}<br>
|
||||
```
|
||||
|
||||
The template above includes the example `sub_template.tpl` below:
|
||||
|
||||
```smarty
|
||||
|
||||
{* foo will be known also in the including template *}
|
||||
{assign var="foo" value="something" scope=parent}
|
||||
{$foo="something" scope=parent}
|
||||
|
||||
{* bar is assigned only local in the including template *}
|
||||
{assign var="bar" value="value"} {* or *}
|
||||
{$var="value"}
|
||||
|
||||
```
|
||||
|
||||
You can assign a variable to root of the current root tree. The variable
|
||||
is seen by all templates using the same root tree.
|
||||
|
||||
```smarty
|
||||
{assign var=foo value="bar" scope="root"}
|
||||
```
|
||||
|
||||
A global variable is seen by all templates.
|
||||
|
||||
```smarty
|
||||
{assign var=foo value="bar" scope="global"} {* or *}
|
||||
{assign "foo" "bar" scope="global"} {* short-hand, or *}
|
||||
{$foo="bar" scope="global"}
|
||||
```
|
||||
|
||||
To access `{assign}` variables from a php script use
|
||||
[`getTemplateVars()`](../../programmers/api-functions/api-get-template-vars.md).
|
||||
Here's the template that creates the variable `$foo`.
|
||||
|
||||
```smarty
|
||||
{assign var="foo" value="Smarty"} {* or *}
|
||||
{$foo="Smarty"}
|
||||
```
|
||||
|
||||
The template variables are only available after/during template
|
||||
execution as in the following script.
|
||||
|
||||
```php
|
||||
<?php
|
||||
|
||||
// this will output nothing as the template has not been executed
|
||||
echo $smarty->getTemplateVars('foo');
|
||||
|
||||
// fetch the template to a variable
|
||||
$whole_page = $smarty->fetch('index.tpl');
|
||||
|
||||
// this will output 'smarty' as the template has been executed
|
||||
echo $smarty->getTemplateVars('foo');
|
||||
|
||||
$smarty->assign('foo','Even smarter');
|
||||
|
||||
// this will output 'Even smarter'
|
||||
echo $smarty->getTemplateVars('foo');
|
||||
```
|
||||
|
||||
The following functions can also *optionally* assign template variables: [`{capture}`](#language.function.capture),
|
||||
[`{include}`](#language.function.include),
|
||||
[`{insert}`](#language.function.insert),
|

# {block}
|
||||
|
||||
`{block}` is used to define a named area of template source for template
|
||||
inheritance. For details see section of [Template
|
||||
Inheritance](../../programmers/advanced-features/advanced-features-template-inheritance.md).
|
||||
|
||||
The `{block}` template source area of a child template will replace the
|
||||
corresponding areas in the parent template(s).
|
||||
|
||||
Optionally `{block}` areas of child and parent templates can be merged
|
||||
into each other. You can append or prepend the parent `{block}` content
|
||||
by using the `append` or `prepend` option flag with the child's `{block}`
|
||||
definition. With `{$smarty.block.parent}` the `{block}` content of
|
||||
the parent template can be inserted at any location of the child
|
||||
`{block}` content. `{$smarty.block.child}` inserts the `{block}` content
|
||||
of the child template at any location of the parent `{block}`.
|
||||
|
||||
`{blocks}'s` can be nested.
|
||||
|
||||
## Attributes
|
||||
|
||||
| Attribute Name | Required | Description |
|
||||
|----------------|----------|----------------------------------------------------------------------------------------------------------------------|
|
||||
| name | yes | The name of the template source block |
|
||||
| assign | no | The name of variable to assign the output of the block to. |
|
||||
|
||||
> **Note**
|
||||
>
|
||||
> The assign attribute only works on the block that actually gets executed, so you may need
|
||||
> to add it to each child block as well.
|
||||
|

|
||||
## Option Flags (in child templates only):
|
||||
|
||||
| Name | Description |
|
||||
|---------|-----------------------------------------------------------------------------------------|
|
||||
| append | The `{block}` content will be appended to the content of the parent template `{block}` |
|
||||
| prepend | The `{block}` content will be prepended to the content of the parent template `{block}` |
|
||||
| hide | Ignore the block content if no child block of same name is existing. |
|
||||
| nocache | Disables caching of the `{block}` content |

# {call}
|
||||
|
||||
`{call}` is used to call a template function defined by the
|
||||
[`{function}`](./language-function-function.md) tag just like a plugin
|
||||
function.
|
||||
|
||||
> **Note**
|
||||
>
|
||||
> Template functions are defined global. Since the Smarty compiler is a
|

||||
> template. Otherwise you can directly use the function as
|
||||
> `{funcname ...}` in the template.
|
||||
|
||||
- The `{call}` tag must have the `name` attribute which contains the
|
||||
name of the template function.
|
||||
|
||||
- Values for variables can be passed to the template function as
|
||||
[attributes](../language-basic-syntax/language-syntax-attributes.md).

# {capture}
|
||||
|

`{capture}` is used to collect the output of the template between the
|
||||
tags into a variable instead of displaying it. Any content between
|
||||
`{capture name='foo'}` and `{/capture}` is collected into the variable
|
||||
specified in the `name` attribute.
|
||||
|
||||
The captured content can be used in the template from the variable
|
||||
[`$smarty.capture.foo`](../language-variables/language-variables-smarty.md#smartycapture-languagevariablessmartycapture) where "foo"
|
||||
is the value passed in the `name` attribute. If you do not supply the

`name` attribute, then "default" will be used as the name ie

`$smarty.capture.default`.

|
||||
|
||||
## Examples
|
||||
|
||||
```smarty
|
||||
{* we don't want to print a div tag unless content is displayed *}
|
||||
{capture name="banner"}
|
||||
{capture "banner"} {* short-hand *}
|
||||
{include file="get_banner.tpl"}
|
||||
{/capture}
|
||||
|
||||
{if $smarty.capture.banner ne ""}
|
||||
<div id="banner">{$smarty.capture.banner}</div>
|
||||
{/if}
|
||||
```
|
||||
|
||||
This example demonstrates the capture function.
|
||||
```smarty
|
||||
|
||||
{capture name=some_content assign=popText}
|
||||
{capture some_content assign=popText} {* short-hand *}
|
||||
The server is {$my_server_name|upper} at {$my_server_addr}<br>
|
||||
Your ip is {$my_ip}.
|
||||
{/capture}
|
||||
<a href="#">{$popText}</a>
|
||||
```
|
||||
|
||||
|
||||
This example also demonstrates how multiple calls of capture can be used
|
||||
to create an array with captured content.
|
||||
|
||||
```smarty
|
||||
{capture append="foo"}hello{/capture}I say just {capture append="foo"}world{/capture}
|
||||
{foreach $foo as $text}{$text} {/foreach}
|
||||
```
|
||||
|
||||
The above example will output:
|
||||
|
||||
```
|
||||
I say just hello world
|
||||
```

# {debug}

`{debug}` dumps the debug console to the page. This works regardless of
|
||||
the [debug](../chapter-debugging-console.md) settings in the php script.
|
||||
Since this gets executed at runtime, this is only able to show the

[assigned](../../programmers/api-functions/api-assign.md) variables; not the templates that are in use.

However, you can see all the currently available variables within the

If caching is enabled and a page is loaded from cache `{debug}` does

show only the variables which assigned for the cached page.

In order to see also the variables which have been locally assigned
|

within the template it does make sense to place the `{debug}` tag at the

end of the template.

# {extends}
|

`{extends}` tags are used in child templates in template inheritance for
|

extending parent templates. For details see section of [Template
|
||||
Inheritance](../../programmers/advanced-features/advanced-features-template-inheritance.md).
|
||||
|
||||
- The `{extends}` tag must be on the first line of the template.
|

|
||||
- If a child template extends a parent template with the `{extends}`
|
||||
tag it may contain only `{block}` tags. Any other template content
|
||||
is ignored.

|
||||
- Use the syntax for [template resources](../../programmers/resources.md) to extend files
|
||||
outside the [`$template_dir`](../../programmers/api-variables/variable-template-dir.md) directory.

The `{for}{forelse}` tag is used to create simple loops. The following different formats are supported:
|
||||
|
||||
- `{for $var=$start to $end}` simple loop with step size of 1.
|
||||
|

`{foreach}` is used for looping over arrays of data. `{foreach}` has a
|
||||
simpler and cleaner syntax than the
|
||||
[`{section}`](./language-function-section.md) loop, and can also loop over
|
||||
associative arrays.

```
|

||||
> is new to Smarty 3, however the Smarty 2.x syntax
|

> `{foreach from=$myarray key="mykey" item="myitem"}` is still
|
||||
> supported.
|
||||
|
||||
- `{foreach}` loops can be nested.
|
||||
|
||||
- The `array` variable, usually an array of values, determines the
|
||||
number of times `{foreach}` will loop. You can also pass an integer
|
||||
for arbitrary loops.
|
||||
|
||||
- `{foreachelse}` is executed when there are no values in the `array`
|
||||
variable.
|
||||
|
||||
- `{foreach}` properties are [`@index`](#index),
|
||||
[`@iteration`](#iteration),
|
||||
[`@first`](#first),
|
||||
[`@last`](#last),
|
||||
[`@show`](#show),
|
||||
[`@total`](#total).
|
||||
|
||||
- `{foreach}` constructs are [`{break}`](#break),
|
||||
[`{continue}`](#continue).
|
||||
|
||||
- Instead of specifying the `key` variable you can access the current
|
||||
key of the loop item by `{$item@key}` (see examples below).
|
||||
|
||||
> **Note**
|
||||
>
|
||||
> The `$var@property` syntax is new to Smarty 3, however when using the
|
||||
> Smarty 2 `{foreach from=$myarray key="mykey" item="myitem"}` style
|

> syntax, the `$smarty.foreach.name.property` syntax is still supported.

> **Note**
|
||||
>
|
||||
> Although you can retrieve the array key with the syntax
|
||||
> `{foreach $myArray as $myKey => $myValue}`, the key is always

A database (PDO) example of looping over search results. This example is
|
||||
looping over a PHP iterator instead of an array().
|
||||
|
||||
```php
|
||||
<?php
|
||||
include('Smarty.class.php');
|
||||
|
||||
$smarty = new Smarty;
|
||||
|
||||
$dsn = 'mysql:host=localhost;dbname=test';
|
||||
$login = 'test';
|
||||
$passwd = 'test';
|
||||
|
||||
// setting PDO to use buffered queries in mysql is
|
||||
// important if you plan on using multiple result cursors
|
||||
// in the template.
|
||||
|
||||
$db = new PDO($dsn, $login, $passwd, array(
|
||||
PDO::MYSQL_ATTR_USE_BUFFERED_QUERY => true));
|
||||
|
||||
$res = $db->prepare("select * from users");
|
||||
$res->execute();
|
||||
$res->setFetchMode(PDO::FETCH_LAZY);
|
||||
|
||||
// assign to smarty
|
||||
$smarty->assign('res',$res);
|
||||
|
||||
$smarty->display('index.tpl');?>
|
||||
```
|
||||
|
||||
```smarty
|
||||
{foreach $res as $r}
|
||||
{$r.id}
|
||||
{$r.name}
|
||||
{foreachelse}
|
||||
.. no results ..
|
||||
{/foreach}
|
||||
```
|
||||
|
||||
The above is assuming the results contain the columns named `id` and
|
||||
`name`.
|
||||
|
||||
What is the advantage of an iterator vs. looping over a plain old array?
|
||||
With an array, all the results are accumulated into memory before being
|
||||
looped. With an iterator, each result is loaded/released within the
|
||||
loop. This saves processing time and memory, especially for very large
|
||||
result sets.
|
||||
|
||||
## @index
|
||||
|
||||
`index` contains the current array index, starting with zero.
|
||||
|
||||
```smarty
|
||||
{* output empty row on the 4th iteration (when index is 3) *}
|
||||
<table>
|
||||
{foreach $items as $i}
|
||||
{if $i@index eq 3}
|
||||
{* put empty table row *}
|
||||
<tr><td>nbsp;</td></tr>
|
||||
{/if}
|
||||
<tr><td>{$i.label}</td></tr>
|
||||
{/foreach}
|
||||
</table>
|
||||
```
|
||||
|
||||
|
||||
## @iteration
|
||||
|
||||
`iteration` contains the current loop iteration and always starts at
|
||||
one, unlike [`index`](#index). It is incremented by one
|
||||
on each iteration.
|
||||
|
||||
The *"is div by"* operator can be used to detect a specific iteration.
|
||||
Here we bold-face the name every 4th iteration.
|
||||
|
||||
```smarty
|
||||
{foreach $myNames as $name}
|
||||
{if $name@iteration is div by 4}
|
||||
<b>{$name}</b>
|
||||
{/if}
|
||||
{$name}
|
||||
{/foreach}
|
||||
```
|
||||
|
||||
The *"is even by"* and *"is odd by"* operators can be used to
|
||||
alternate something every so many iterations. Choosing between even or
|
||||
odd rotates which one starts. Here we switch the font color every 3rd
|
||||
iteration.
|
||||
|
||||
```smarty
|
||||
{foreach $myNames as $name}
|
||||
{if $name@iteration is even by 3}
|
||||
<span style="color: #000">{$name}</span>
|
||||
{else}
|
||||
<span style="color: #eee">{$name}</span>
|
||||
{/if}
|
||||
{/foreach}
|
||||
```
|
||||
|
||||
This will output something similar to this:
|
||||
|
||||
```html
|
||||
<span style="color: #000">...</span>
|
||||
<span style="color: #000">...</span>
|
||||
<span style="color: #000">...</span>
|
||||
<span style="color: #eee">...</span>
|
||||
<span style="color: #eee">...</span>
|
||||
<span style="color: #eee">...</span>
|
||||
<span style="color: #000">...</span>
|
||||
<span style="color: #000">...</span>
|
||||
<span style="color: #000">...</span>
|
||||
<span style="color: #eee">...</span>
|
||||
<span style="color: #eee">...</span>
|
||||
<span style="color: #eee">...</span>
|
||||
...
|
||||
```
|
||||
|
||||
## @first
|
||||
|
||||
`first` is TRUE if the current `{foreach}` iteration is the initial one.
|
||||
Here we display a table header row on the first iteration.
|
||||
|
||||
```smarty
|
||||
{* show table header at first iteration *}
|
||||
<table>
|
||||
{foreach $items as $i}
|
||||
{if $i@first}
|
||||
<tr>
|
||||
<th>key</td>
|
||||
<th>name</td>
|
||||
</tr>
|
||||
{/if}
|
||||
<tr>
|
||||
<td>{$i@key}</td>
|
||||
<td>{$i.name}</td>
|
||||
</tr>
|
||||
{/foreach}
|
||||
</table>
|
||||
```
|
||||
|
||||
## @last
|
||||
|
||||
`last` is set to TRUE if the current `{foreach}` iteration is the final
|
||||
one. Here we display a horizontal rule on the last iteration.
|
||||
|
||||
```smarty
|
||||
{* Add horizontal rule at end of list *}
|
||||
{foreach $items as $item}
|
||||
<a href="#{$item.id}">{$item.name}</a>{if $item@last}<hr>{else},{/if}
|
||||
{foreachelse}
|
||||
... no items to loop ...
|
||||
{/foreach}
|
||||
```
|
||||
|
||||
## @show
|
||||
|
||||
The show `show` property can be used after the execution of a
|
||||
`{foreach}` loop to detect if data has been displayed or not. `show` is
|
||||
a boolean value.
|
||||
|
||||
```smarty
|
||||
<ul>
|
||||
{foreach $myArray as $name}
|
||||
<li>{$name}</li>
|
||||
{/foreach}
|
||||
</ul>
|
||||
{if $name@show} do something here if the array contained data {/if}
|
||||
```
|
||||
|
||||
## @total
|
||||
|
||||
`total` contains the number of iterations that this `{foreach}` will
|
||||
loop. This can be used inside or after the `{foreach}`.
|
||||
|
||||
```smarty
|
||||
{* show number of rows at end *}
|
||||
{foreach $items as $item}
|
||||
{$item.name}<hr/>
|
||||
{if $item@last}
|
||||
<div id="total">{$item@total} items</div>
|
||||
{/if}
|
||||
{foreachelse}
|
||||
... no items to loop ...
|
||||
{/foreach}
|
||||

|
||||

|
||||

|
||||
|
||||
## {break}
|
||||
|
||||
`{break}` aborts the iteration of the array
|
||||
|
||||
```smarty
|
||||
{$data = [1,2,3,4,5]}
|
||||
{foreach $data as $value}
|
||||
{if $value == 3}
|
||||
{* abort iterating the array *}

|
||||
{*
|
||||
prints: 1 2
|
||||
*}
|
||||
```
|
||||
|
||||
## {continue}
|
||||
|
||||
`{continue}` leaves the current iteration and begins with the next
|
||||
iteration.
|
||||
|
||||
```smarty
|
||||
{$data = [1,2,3,4,5]}
|

# {function}
|
||||
|
||||
`{function}` is used to create functions within a template and call them
|
||||
just like a plugin function. Instead of writing a plugin that generates
|
||||
presentational content, keeping it in the template is often a more
|
||||
manageable choice. It also simplifies data traversal, such as deeply
|
||||
nested menus.
|
||||
|
||||
> **Note**
|
||||
>
|
||||
> Template functions are defined global. Since the Smarty compiler is a
|
||||
> single-pass compiler, The [`{call}`](#language.function.call) tag must
|
||||
> be used to call a template function defined externally from the given
|
||||
> template. Otherwise, you can directly use the function as
|
||||
> `{funcname ...}` in the template.
|
||||
|
||||
## Attributes
|
||||
|
||||
| Attribute Name | Required | Description |
|
||||
|----------------|----------|---------------------------------------------------------------|
|
||||
| name | Yes | The name of the template function |
|
||||
| \[var \...\] | No | default variable value to pass local to the template function |
|
||||
|
||||
- The `{function}` tag must have the `name` attribute which contains
|
||||
the name of the template function. A tag with this name can be
|
||||
used to call the template function.
|
||||
|
||||
- Default values for variables can be passed to the template function
|
||||
as [attributes](../language-basic-syntax/language-syntax-attributes.md). Like in PHP function
|
||||
declarations you can only use scalar values as default. The default
|
||||
values can be overwritten when the template function is being
|
||||
called.
|
||||
|
||||
- You can use all variables from the calling template inside the
|
||||
template function. Changes to variables or new created variables
|
||||
inside the template function have local scope and are not visible
|
||||
inside the calling template after the template function is executed.
|
||||
|
||||
|
||||
|
||||
> **Note**
|
||||
>
|
||||
> You can pass any number of parameter to the template function when it
|
||||
> is called. The parameter variables must not be declared in the
|
||||
> `{funcname ...}` tag unless you what to use default values. Default
|
||||
> values must be scalar and can not be variable. Variables must be
|
||||
> passed when the template is called.
|
||||
|
||||
## Examples

||||
|
||||
```smarty

# {if},{elseif},{else}
|
||||
|
||||
`{if}` statements in Smarty have much the same flexibility as PHP
|
||||
[if](https://www.php.net/if) statements, with a few added features for the
|
||||
template engine. Every `{if}` must be paired with a matching `{/if}`.
|
||||
`{else}` and `{elseif}` are also permitted. All PHP conditionals and
|
||||
functions are recognized, such as *\|\|*, *or*, *&&*, *and*,
|
||||
*is_array()*, etc.
|
||||
|
||||
If security is enabled, only PHP functions from `$php_functions` property
|
||||
of the security policy are allowed. See the
|
||||
[Security](../../programmers/advanced-features/advanced-features-security.md) section for details.
|
||||
|
||||
The following is a list of recognized qualifiers, which must be
|
||||
separated from surrounding elements by spaces. Note that items listed in
|
||||
\[brackets\] are optional. PHP equivalents are shown where applicable.

# {include}
|
||||
|
||||
`{include}` tags are used for including other templates in the current
|
||||
template. Any variables available in the current template are also
|
||||
available within the included template.
|
||||
|
||||
## Attributes
|
||||
|
||||
| Attribute Name | Required | Description |
|
||||
|----------------|----------|--------------------------------------------------------------------------------------------|
|
||||
| file | Yes | The name of the template file to include |
|
||||
| assign | No | The name of the variable that the output of include will be assigned to |
|
||||
| cache_lifetime | No | Enable caching of this subtemplate with an individual cache lifetime |
|
||||
| compile_id | No | Compile this subtemplate with an individual compile_id |
|
||||
| cache_id | No | Enable caching of this subtemplate with an individual cache_id |
|
||||
| scope | No | Define the scope of all in the subtemplate assigned variables: 'parent','root' or 'global' |
|
||||
| \[var \...\] | No | variable to pass local to template |
|
||||
|
||||
|
||||
- The `{include}` tag must have the `file` attribute which contains
|
||||
the template resource path.
|
||||
|
||||
- Setting the optional `assign` attribute specifies the template
|
||||
variable that the output of `{include}` is assigned to, instead of
|
||||
being displayed. Similar to [`{assign}`](./language-function-assign.md).
|
||||
|
||||
- Variables can be passed to included templates as
|
||||
[attributes](../language-basic-syntax/language-syntax-attributes.md). Any variables explicitly
|
||||
passed to an included template are only available within the scope
|
||||
of the included file. Attribute variables override current template
|
||||
variables, in the case when they are named the same.
|
||||
|
||||
- You can use all variables from the including template inside the
|
||||
included template. But changes to variables or new created variables
|
||||
inside the included template have local scope and are not visible
|
||||
inside the including template after the `{include}` statement. This
|
||||
default behaviour can be changed for all variables assigned in the
|
||||
included template by using the scope attribute at the `{include}`
|
||||
statement or for individual variables by using the scope attribute
|
||||
at the [`{assign}`](./language-function-assign.md) statement. The later
|
||||
is useful to return values from the included template to the
|
||||
including template.
|
||||
|
||||
- Use the syntax for [template resources](../../programmers/resources.md) to `{include}`
|
||||
files outside of the [`$template_dir`](../../programmers/api-variables/variable-template-dir.md)
|
||||
directory.
|
||||
|
||||
## Option Flags
|
||||
|
||||
| Name | Description |
|
||||
|---------|--------------------------------------------------------------------------------------|
|
||||
| nocache | Disables caching of this subtemplate |
|
||||
| caching | Enable caching of this subtemplate |
|
||||
| inline | If set, merge the compile-code of the subtemplate into the compiled calling template |

||||
</head>
|
||||
<body>

|
||||
|
||||
{* body of template goes here, the $tpl_name variable
|
||||

|
||||

|
||||
{include file="$tpl_name.tpl"}
|
||||
|
||||
{* using shortform file attribute *}
|
||||
{include 'page_footer.tpl'}
|
||||
</body>
|
||||
</html>
|
||||
```
|
||||
|
||||
```smarty
|
||||
|
||||
{include 'links.tpl' title='Newest links' links=$link_array}
|
||||
{* body of template goes here *}
|
||||
{include 'footer.tpl' foo='bar'}
|
||||
|
||||
```
|
||||
|
||||
The template above includes the example `links.tpl` below
|
||||
|
||||
```smarty
|
||||
<div id="box">
|
||||
<h3>{$title}{/h3>
|
||||
<ul>
|
||||
{foreach from=$links item=l}
|
||||
.. do stuff ...
|
||||
</foreach}
|
||||
</ul>
|
||||
</div>
|
||||
```
|
||||
Variables assigned in the included template will be seen in the
|
||||
including template.
|
||||
|
||||
```smarty
|
||||
{include 'sub_template.tpl' scope=parent}
|
||||
...
|
||||
{* display variables assigned in sub_template *}
|
||||
{$foo}<br>
|
||||
{$bar}<br>
|
||||
...
|
||||
```
|
||||
|
||||
The template above includes the example `sub_template.tpl` below
|
||||
|
||||
```smarty
|
||||
...
|
||||
{assign var=foo value='something'}
|
||||
{assign var=bar value='value'}
|
||||
...
|
||||
```
|
||||
|
||||
The included template will not be cached.
|
||||
|
||||
```smarty
|
||||
{include 'sub_template.tpl' nocache}
|
||||
...
|
||||
```
|
||||
|
||||
In this example included template will be cached with an individual
|
||||
cache lifetime of 500 seconds.
|
||||
|
||||
```smarty
|
||||
{include 'sub_template.tpl' cache_lifetime=500}
|
||||
...
|
||||
```
|
||||
|
||||
In this example included template will be cached independent of the
|
||||
global caching setting.
|
||||
|
||||
```smarty
|
||||
{include 'sub_template.tpl' caching}
|
||||
...
|
||||
```
|
||||
|
||||
This example assigns the contents of `nav.tpl` to the `$navbar`
|
||||
variable, which is then output at both the top and bottom of the page.
|
||||
|
||||
```smarty
|
||||
<body>
|
||||
{include 'nav.tpl' assign=navbar}
|
||||
{include 'header.tpl' title='Smarty is cool'}
|
||||
{$navbar}
|
||||
{* body of template goes here *}
|
||||
{$navbar}
|
||||
{include 'footer.tpl'}
|
||||
</body>
|
||||
```
|
||||
|
||||
This example includes another template relative to the directory of the
|
||||
current template.
|
||||
|
||||
```smarty

# {insert}
|

|
||||
> **Note**
|
||||
>
|
||||
> `{insert}` tags are deprecated from Smarty, and should not be used.
|
||||
> Put your PHP logic in PHP scripts or plugin functions instead.
|

> As of Smarty 3.1 the `{insert}` tags are only available from

|

|

`{insert}` tags work much like [`{include}`](./language-function-include.md)
|
||||
tags, except that `{insert}` tags are NOT cached when template
|
||||
[caching](../../programmers/caching.md) is enabled. They will be executed on every
|
||||
invocation of the template.
|
||||
|
||||
| Attribute Name | Required | Description |
|
||||
|----------------|----------|----------------------------------------------------------------------------------|
|
||||
| name | Yes | The name of the insert function (insert_`name`) or insert plugin |
|
||||
| assign | No | The name of the template variable the output will be assigned to |
|
||||
| script | No | The name of the php script that is included before the insert function is called |
|
||||
| \[var \...\] | No | variable to pass to insert function |
|
||||
|
||||
## Examples
|
||||
|
||||
Let's say you have a template with a banner slot at the top of the
|
||||
page. The banner can contain any mixture of HTML, images, flash, etc. so
|
||||
we can't just use a static link here, and we don't want this contents
|
||||
cached with the page. In comes the {insert} tag: the template knows
|
||||
\#banner\_location\_id\# and \#site\_id\# values (gathered from a
|
||||
[config file](../config-files.md)), and needs to call a function to get the
|
||||
banner contents.
|
||||
|
||||
```smarty
|
||||
{* example of fetching a banner *}
|
||||
{insert name="getBanner" lid=#banner_location_id# sid=#site_id#}
|
||||
{insert "getBanner" lid=#banner_location_id# sid=#site_id#} {* short-hand *}
|
||||
```
|
||||
|
||||
In this example, we are using the name "getBanner" and passing the
|
||||
parameters \#banner\_location\_id\# and \#site\_id\#. Smarty will look
|
||||
for a function named insert\_getBanner() in your PHP application,
|
||||
passing the values of \#banner\_location\_id\# and \#site\_id\# as the
|
||||
first argument in an associative array. All {insert} function names in
|
||||
your application must be prepended with "insert_" to remedy possible
|
||||
function name-space conflicts. Your insert\_getBanner() function should
|
||||
do something with the passed values and return the results. These
|
||||
results are then displayed in the template in place of the {insert} tag.
|
||||
In this example, Smarty would call this function:
|
||||
insert_getBanner(array("lid" => "12345","sid" => "67890"));
|
||||
and display the returned results in place of the {insert} tag.
|
||||
|
||||
- If you supply the `assign` attribute, the output of the `{insert}`
|
||||
tag will be assigned to this template variable instead of being
|
||||
output to the template.
|
||||
|
||||
> **Note**
|
||||
>
|
||||
> Assigning the output to a template variable isn't too useful with
|
||||
> [caching](../../programmers/api-variables/variable-caching.md) enabled.
|
||||
|
||||
- If you supply the `script` attribute, this php script will be
|
||||
included (only once) before the `{insert}` function is executed.
|
||||
This is the case where the insert function may not exist yet, and a
|
||||
php script must be included first to make it work.
|
||||
|
||||
The path can be either absolute, or relative to
|
||||
[`$trusted_dir`](../../programmers/api-variables/variable-trusted-dir.md). If security is enabled,
|
||||
then the script must be located in the `$trusted_dir` path of the
|
||||
security policy. See the [Security](../../programmers/advanced-features/advanced-features-security.md)
|
||||
section for details.
|
||||
|
||||
The Smarty object is passed as the second argument. This way you can
|
||||
reference and modify information in the Smarty object from within the
|
||||
`{insert}` function.
|
||||
|
||||
If no PHP script can be found Smarty is looking for a corresponding
|
||||
insert plugin.

>
|
||||

# {literal}

`{literal}` tags allow a block of data to be taken literally. This is
|
||||
typically used around Javascript or stylesheet blocks where {curly

braces} would interfere with the template
|

[delimiter](../../programmers/api-variables/variable-left-delimiter.md) syntax. Anything within

`{literal}{/literal}` tags is not interpreted, but displayed as-is. If

delimiters instead.

# {section}, {sectionelse}

A `{section}` is for looping over **sequentially indexed arrays of
|

data**, unlike [`{foreach}`](./language-function-foreach.md) which is used
|
||||
to loop over a **single associative array**. Every `{section}` tag must

| Attribute Name | Required | Description |
|
||||
|----------------|----------|--------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------|
|
||||
| name | Yes | The name of the section |
|
||||
| loop | Yes | Value to determine the number of loop iterations |
|
||||
| start | No | The index position that the section will begin looping. If the value is negative, the start position is calculated from the end of the array. For example, if there are seven values in the loop array and start is -2, the start index is 5. Invalid values (values outside of the length of the loop array) are automatically truncated to the closest valid value. Defaults to 0. |
|
||||
| step | No | The step value that will be used to traverse the loop array. For example, step=2 will loop on index 0, 2, 4, etc. If step is negative, it will step through the array backwards. Defaults to 1. |
|
||||
| max | No | Sets the maximum number of times the section will loop. |
|
||||
| show | No | Determines whether to show this section (defaults to true) |
|
||||
|
||||
## Option Flags
|
||||
|

| Name | Description |
|
||||
|---------|------------------------------------------|
|
||||
| nocache | Disables caching of the `{section}` loop |
|
||||
|
||||
- Required attributes are `name` and `loop`.
|
||||
|
||||
- The `name` of the `{section}` can be anything you like, made up of
|
||||
letters, numbers and underscores, like [PHP
|
||||
variables](https://www.php.net/language.variables).
|
||||
|
||||
- {section}'s can be nested, and the nested `{section}` names must be
|
||||
unique from each other.
|
||||
|
||||
- The `loop` attribute, usually an array of values, determines the
|
||||
number of times the `{section}` will loop. You can also pass an
|
||||
integer as the loop value.
|
||||
|
||||
- When printing a variable within a `{section}`, the `{section}`
|
||||
`name` must be given next to variable name within \[brackets\].
|
||||
|
||||
- `{sectionelse}` is executed when there are no values in the loop
|
||||
variable.
|
||||
|
||||
- A `{section}` also has its own variables that handle `{section}`
|
||||
properties. These properties are accessible as:
|
||||
[`{$smarty.section.name.property}`](../language-variables/language-variables-smarty.md#smartysection-languagevariablessmartyloops)
|
||||
where "name" is the attribute `name`.
|
||||
|
||||
- `{section}` properties are [`index`](#index),
|
||||
[`index_prev`](#index_prev),
|
||||
[`index_next`](#index_next),
|
||||
[`iteration`](#iteration),
|
||||
[`first`](#first),
|
||||
[`last`](#last),
|
||||
[`rownum`](#rownum),
|
||||
[`loop`](#loop), [`show`](#show),
|
||||
[`total`](#total).
|
||||
|
||||
[`assign()`](../../programmers/api-functions/api-assign.md) an array to Smarty
|
||||
|
||||
## Examples
|
||||
|
||||
```php
|
||||
<?php
|
||||
$data = [1000, 1001, 1002];
|
||||
$smarty->assign('custid', $data);
|
||||
```
|
||||
|
||||
The template that outputs the array
|
||||
|
||||
```smarty
|
||||
{* this example will print out all the values of the $custid array *}
|
||||
{section name=customer loop=$custid}
|
||||
{section customer $custid} {* short-hand *}
|
||||
id: {$custid[customer]}<br />
|
||||
{/section}
|
||||
<hr />
|
||||
{* print out all the values of the $custid array reversed *}
|
||||
{section name=foo loop=$custid step=-1}
|
||||
{section foo $custid step=-1} {* short-hand *}
|
||||
{$custid[foo]}<br />
|
||||
{/section}
|
||||
```
|
||||
|
||||
The above example will output:
|
||||
|
||||
```html
|
||||
id: 1000<br />
|
||||
id: 1001<br />
|
||||

|
||||
```
|
||||
|
||||
```smarty
|
||||

|
||||
{$smarty.section.foo.index}
|
||||
{/section}
|
||||
<hr />
|
||||
{section name=bar loop=21 max=6 step=-2}
|
||||
{$smarty.section.bar.index}
|
||||
{/section}
|
||||
```
|
||||
|
||||
The above example will output:
|
||||
|
||||
```html
|
||||
10 12 14 16 18
|
||||
<hr />
|
||||
20 18 16 14 12 10
|
||||
```
|
||||
|
||||
The `name` of the `{section}` can be anything you like, see [PHP
|
||||
variables](https://www.php.net/language.variables). It is used to reference
|
||||
the data within the `{section}`.
|
||||
|
||||
```smarty
|
||||
{section name=anything loop=$myArray}
|
||||
{$myArray[anything].foo}
|
||||
{$name[anything]}
|
||||
{$address[anything].bar}
|
||||
{/section}
|
||||
```
|
||||
|
||||
This is an example of printing an associative array of data with a
|
||||
`{section}`. Following is the php script to assign the `$contacts` array
|
||||
to Smarty.
|
||||
|
||||
```php
|
||||
<?php
|
||||
$data = [
|
||||
['name' => 'John Smith', 'home' => '555-555-5555',
|
||||
'cell' => '666-555-5555', 'email' => 'john@myexample.com'],
|
||||
['name' => 'Jack Jones', 'home' => '777-555-5555',
|
||||
'cell' => '888-555-5555', 'email' => 'jack@myexample.com'],
|
||||
['name' => 'Jane Munson', 'home' => '000-555-5555',
|
||||
'cell' => '123456', 'email' => 'jane@myexample.com']
|
||||
];
|
||||
$smarty->assign('contacts',$data);
|
||||
```
|
||||
|
||||
The template to output `$contacts`
|
||||
|
||||
```smarty
|
||||
{section name=customer loop=$contacts}
|
||||
<p>
|
||||
name: {$contacts[customer].name}<br />
|
||||
home: {$contacts[customer].home}<br />
|
||||
cell: {$contacts[customer].cell}<br />
|
||||
e-mail: {$contacts[customer].email}
|
||||
</p>
|
||||
{/section}
|
||||
```
|
||||
|
||||
The above example will output:
|
||||
|
||||
```html
|
||||
<p>
|
||||
name: John Smith<br />
|
||||
home: 555-555-5555<br />
|
||||
cell: 666-555-5555<br />
|
||||
e-mail: john@myexample.com
|
||||
</p>
|
||||
<p>
|
||||
name: Jack Jones<br />
|
||||
home: 777-555-5555<br />
|
||||
cell: 888-555-5555<br />
|
||||
e-mail: jack@myexample.com
|
||||
</p>
|
||||
<p>
|
||||
name: Jane Munson<br />
|
||||
home: 000-555-5555<br />
|
||||
cell: 123456<br />
|
||||
e-mail: jane@myexample.com
|
||||
</p>
|
||||
```
|
||||
|
||||
This example assumes that `$custid`, `$name` and `$address` are all
|
||||
arrays containing the same number of values. First the php script that
|
||||
assign's the arrays to Smarty.
|
||||
|
||||
```php
|
||||
<?php
|
||||
|
||||
$id = [1001,1002,1003];
|
||||
$smarty->assign('custid',$id);
|
||||
|
||||
$fullnames = ['John Smith','Jack Jones','Jane Munson'];
|
||||
$smarty->assign('name',$fullnames);
|
||||
|
||||
$addr = ['253 Abbey road', '417 Mulberry ln', '5605 apple st'];
|
||||
$smarty->assign('address',$addr);
|
||||
```
|
||||
|
||||
The `loop` variable only determines the number of times to loop. You can
|
||||
access ANY variable from the template within the `{section}`. This is
|
||||
useful for looping multiple arrays. You can pass an array which will
|
||||
determine the loop count by the array size, or you can pass an integer
|
||||
to specify the number of loops.
|
||||
|
||||
```smarty
|
||||
{section name=customer loop=$custid}
|
||||
<p>
|
||||
id: {$custid[customer]}<br />
|
||||
name: {$name[customer]}<br />
|
||||
address: {$address[customer]}
|
||||
</p>
|
||||
{/section}
|
||||
```
|
||||
|
||||
The above example will output:
|
||||
|
||||
```html
|
||||
<p>
|
||||
id: 1000<br />
|
||||
name: John Smith<br />
|
||||
address: 253 Abbey road
|
||||
</p>
|
||||
<p>
|
||||
id: 1001<br />
|
||||
name: Jack Jones<br />
|
||||
address: 417 Mulberry ln
|
||||
</p>
|
||||
<p>
|
||||
id: 1002<br />
|
||||
name: Jane Munson<br />
|
||||
address: 5605 apple st
|
||||
</p>
|
||||
```
|
||||
|
||||
{section}'s can be nested as deep as you like. With nested
|
||||
{section}'s, you can access complex data structures, such as
|
||||
multidimensional arrays. This is an example `.php` script that
|
||||
assigns the arrays.
|
||||
|
||||
```php
|
||||

In this template, *$contact_type\[customer\]* is an array of contact
|
||||
types for the current customer.
|

{$contact_type[customer][contact]}: {$contact_info[customer][contact]}<br />
|
||||
{/section}
|
||||
{/section}
|
||||
```
|
||||
|
||||
The above example will output:
|
||||
|
||||
```html

Results of a database search (eg ADODB or PEAR) are assigned to Smarty
|
||||
|
||||
```php
|
||||
<?php
|
||||
$sql = 'select id, name, home, cell, email from contacts '
|
||||
."where name like '$foo%' ";
|
||||
$smarty->assign('contacts', $db->getAll($sql));
|
||||
```
|
||||
|
||||
The template to output the database result in a HTML table
|
||||
|
||||
```smarty
|
||||
<table>
|
||||
<tr><th> </th><th>Name></th><th>Home</th><th>Cell</th><th>Email</th></tr>
|
||||
{section name=co loop=$contacts}
|
||||
<tr>
|
||||
<td><a href="view.php?id={$contacts[co].id}">view<a></td>
|
||||
<td>{$contacts[co].name}</td>
|
||||
<td>{$contacts[co].home}</td>
|
||||
<td>{$contacts[co].cell}</td>
|
||||
<td>{$contacts[co].email}</td>
|
||||
<tr>
|
||||
{sectionelse}
|
||||
<tr><td colspan="5">No items found</td></tr>
|
||||
{/section}
|
||||
</table>
|
||||
```
|
||||
|
||||
## .index
|
||||
`index` contains the current array index, starting with zero or the
|
||||
`start` attribute if given. It increments by one or by the `step`
|
||||
attribute if given.
|
||||
|
||||
> **Note**
|
||||
>
|
||||
> If the `step` and `start` properties are not modified, then this works
|
||||
> the same as the [`iteration`](#iteration) property,
|
||||
> except it starts at zero instead of one.
|
||||
|
||||
> **Note**
|
||||
>
|
||||
> `$custid[customer.index]` and `$custid[customer]` are identical.
|
||||
|
||||
```smarty
|
||||
{section name=customer loop=$custid}
|
||||
{$smarty.section.customer.index} id: {$custid[customer]}<br />
|
||||
{/section}
|
||||
```
|
||||
|
||||
The above example will output:
|
||||
|
||||
```html
|
||||
0 id: 1000<br />
|
||||
1 id: 1001<br />
|
||||
2 id: 1002<br />
|
||||
```
|
||||
|
||||
|
||||
## .index_prev
|
||||
|
||||
`index_prev` is the previous loop index. On the first loop, this is set to -1.
|
||||
|
||||
## .index_next
|
||||
|
||||
`index_next` is the next loop index. On the last loop, this is still one
|
||||
more than the current index, respecting the setting of the `step`
|
||||
attribute, if given.
|
||||
|
||||
```php
|
||||
<?php
|
||||
$data = [1001,1002,1003,1004,1005];
|
||||
$smarty->assign('rows',$data);
|
||||
```
|
||||
|
||||
Template to output the above array in a table
|
||||
|
||||
```smarty
|
||||
{* $rows[row.index] and $rows[row] are identical in meaning *}
|
||||
<table>
|
||||
<tr>
|
||||
<th>index</th><th>id</th>
|
||||
<th>index_prev</th><th>prev_id</th>
|
||||
<th>index_next</th><th>next_id</th>
|
||||
</tr>
|
||||
{section name=row loop=$rows}
|
||||
<tr>
|
||||
<td>{$smarty.section.row.index}</td><td>{$rows[row]}</td>
|
||||
<td>{$smarty.section.row.index_prev}</td><td>{$rows[row.index_prev]}</td>
|
||||
<td>{$smarty.section.row.index_next}</td><td>{$rows[row.index_next]}</td>
|
||||
</tr>
|
||||
{/section}
|
||||
</table>
|
||||
```
|
||||
|
||||
The above example will output a table containing the following:
|
||||
|
||||
```
|
||||
index id index_prev prev_id index_next next_id
|
||||
0 1001 -1 1 1002
|
||||
1 1002 0 1001 2 1003
|
||||
2 1003 1 1002 3 1004
|
||||
3 1004 2 1003 4 1005
|
||||
4 1005 3 1004 5
|
||||
```
|
||||
|
||||
## .iteration
|
||||
|
||||
`iteration` contains the current loop iteration and starts at one.
|
||||
|
||||
> **Note**
|
||||
>
|
||||
> This is not affected by the `{section}` properties `start`, `step` and
|
||||
> `max`, unlike the [`index`](#index) property.
|
||||
> `iteration` also starts with one instead of zero unlike `index`.
|
||||
> [`rownum`](#rownum) is an alias to `iteration`, they
|
||||
> are identical.
|
||||
|
||||
```php
|
||||
<?php
|
||||
// array of 3000 to 3015
|
||||
$id = range(3000,3015);
|
||||
$smarty->assign('arr', $id);
|
||||
```
|
||||
|
||||
Template to output every other element of the `$arr` array as `step=2`
|
||||
|
||||
```smarty
|
||||
{section name=cu loop=$arr start=5 step=2}
|
||||
iteration={$smarty.section.cu.iteration}
|
||||
index={$smarty.section.cu.index}
|
||||
id={$custid[cu]}<br />
|
||||
{/section}
|
||||
```
|
||||
|
||||
The above example will output:
|
||||
|
||||
```html
|
||||
iteration=1 index=5 id=3005<br />
|
||||
iteration=2 index=7 id=3007<br />
|
||||
iteration=3 index=9 id=3009<br />
|
||||
iteration=4 index=11 id=3011<br />
|
||||
iteration=5 index=13 id=3013<br />
|
||||
iteration=6 index=15 id=3015<br />
|
||||
```
|
||||
|
||||
Another example that uses the `iteration` property to output a table
|
||||
header block every five rows.
|
||||
|
||||
```smarty
|
||||
<table>
|
||||
{section name=co loop=$contacts}
|
||||
{if $smarty.section.co.iteration is div by 5}
|
||||
<tr><th> </th><th>Name></th><th>Home</th><th>Cell</th><th>Email</th></tr>
|
||||
{/if}
|
||||
<tr>
|
||||
<td><a href="view.php?id={$contacts[co].id}">view<a></td>
|
||||
<td>{$contacts[co].name}</td>
|
||||
<td>{$contacts[co].home}</td>
|
||||
<td>{$contacts[co].cell}</td>
|
||||
<td>{$contacts[co].email}</td>
|
||||
<tr>
|
||||
{/section}
|
||||
</table>
|
||||
```
|
||||
|
||||
An example that uses the `iteration` property to alternate a text color every
|
||||
third row.
|
||||
|
||||
```smarty
|
||||
<table>
|
||||
{section name=co loop=$contacts}
|
||||
{if $smarty.section.co.iteration is even by 3}
|
||||
<span style="color: #ffffff">{$contacts[co].name}</span>
|
||||
{else}
|
||||
<span style="color: #dddddd">{$contacts[co].name}</span>
|
||||
{/if}
|
||||
{/section}
|
||||
</table>
|
||||
```
|
||||
|
||||
> **Note**
|
||||
>
|
||||
> The *"is div by"* syntax is a simpler alternative to the PHP mod
|
||||
> operator syntax. The mod operator is allowed:
|
||||
> `{if $smarty.section.co.iteration % 5 == 1}` will work just the same.
|
||||
|
||||
> **Note**
|
||||
>
|
||||
> You can also use *"is odd by"* to reverse the alternating.
|
||||
|
||||
## .first
|
||||
|
||||
`first` is set to TRUE if the current `{section}` iteration is the initial one.
|
||||
|
||||
## .last
|
||||
|
||||
`last` is set to TRUE if the current section iteration is the final one.
|
||||
|
||||
This example loops the `$customers` array, outputs a header block on the
|
||||
first iteration and on the last outputs the footer block. Also uses the
|
||||
[`total`](#total) property.
|
||||
|
||||
```smarty
|
||||
{section name=customer loop=$customers}
|
||||
{if $smarty.section.customer.first}
|
||||
<table>
|
||||
<tr><th>id</th><th>customer</th></tr>
|
||||
{/if}
|
||||
|
||||
<tr>
|
||||
<td>{$customers[customer].id}}</td>
|
||||
<td>{$customers[customer].name}</td>
|
||||
</tr>
|
||||
|
||||
{if $smarty.section.customer.last}
|
||||
<tr><td></td><td>{$smarty.section.customer.total} customers</td></tr>
|
||||
</table>
|
||||
{/if}
|
||||
{/section}
|
||||
```
|
||||
|
||||
## .rownum
|
||||
|
||||
`rownum` contains the current loop iteration, starting with one. It is
|
||||
an alias to [`iteration`](#iteration), they work
|
||||
identically.
|
||||
|
||||
## .loop
|
||||
|
||||
`loop` contains the last index number that this {section} looped. This
|
||||
can be used inside or after the `{section}`.
|
||||
|
||||
```smarty
|
||||
{section name=customer loop=$custid}
|
||||
{$smarty.section.customer.index} id: {$custid[customer]}<br />
|
||||
{/section}
|
||||
There are {$smarty.section.customer.loop} customers shown above.
|
||||
```
|
||||
|
||||
The above example will output:
|
||||
|
||||
```html
|
||||
0 id: 1000<br />
|
||||
1 id: 1001<br />
|
||||
2 id: 1002<br />
|
||||
There are 3 customers shown above.
|
||||
```
|
||||
|
||||
## .show
|
||||
|
||||
`show` is used as a parameter to section and is a boolean value. If
|
||||
FALSE, the section will not be displayed. If there is a `{sectionelse}`
|
||||
present, that will be alternately displayed.
|
||||
|
||||
Boolean `$show_customer_info` has been passed from the PHP application,
|
||||
to regulate whether this section shows.
|
||||
|
||||
```smarty
|
||||
{section name=customer loop=$customers show=$show_customer_info}
|
||||
{$smarty.section.customer.rownum} id: {$customers[customer]}<br />
|
||||
{/section}
|
||||
|
||||
{if $smarty.section.customer.show}
|
||||
the section was shown.
|
||||
{else}
|
||||
the section was not shown.
|
||||
{/if}
|
||||
```
|
||||
|
||||
The above example will output:
|
||||
|
||||
```html
|
||||
1 id: 1000<br />
|
||||
2 id: 1001<br />
|
||||
3 id: 1002<br />
|
||||
|
||||
the section was shown.
|
||||
```
|
||||
|
||||
|
||||
## .total
|
||||
|
||||
`total` contains the number of iterations that this `{section}` will
|
||||
loop. This can be used inside or after a `{section}`.
|
||||
|
||||
```smarty
|
||||
{section name=customer loop=$custid step=2}
|
||||
{$smarty.section.customer.index} id: {$custid[customer]}<br />
|
||||
{/section}
|
||||
There are {$smarty.section.customer.total} customers shown above.

# {setfilter}
|
||||
|
||||
The `{setfilter}...{/setfilter}` block tag allows the definition of
|
||||
template instance's variable filters.
|
||||
|
||||
SYNTAX: `{setfilter filter1\|filter2\|filter3\....}\...{/setfilter}`
|
||||
|
||||
The filter can be:
|
||||
|
||||
- A variable filter plugin specified by it's name.
|
||||
|
||||
- A modifier specified by it's name and optional additional
|
||||
parameter.
|
||||
|
||||
`{setfilter}...{/setfilter}` blocks can be nested. The filter definition
|
||||
of inner blocks does replace the definition of the outer block.
|
||||
|
||||
Template instance filters run in addition to other modifiers and
|
||||
filters. They run in the following order: modifier, default_modifier,
|
||||
$escape_html, registered variable filters, autoloaded variable
|
||||
filters, template instance's variable filters. Everything after
|
||||
default_modifier can be disabled with the `nofilter` flag.
|
||||

# {strip}
|
||||
|
||||
Many times web designers run into the issue where white space and
|
||||
carriage returns affect the output of the rendered HTML (browser
|
||||
"features"), so you must run all your tags together in the template to
|
||||
get the desired results. This usually ends up in unreadable or
|
||||
unmanageable templates.
|
||||
|
||||
Anything within `{strip}{/strip}` tags are stripped of the extra spaces
|
||||
or carriage returns at the beginnings and ends of the lines before they
|
||||
are displayed. This way you can keep your templates readable, and not
|
||||
worry about extra white space causing problems.
|
||||
|
||||
> **Note**
|
||||
>
|
||||
> `{strip}{/strip}` does not affect the contents of template variables,
|
||||
> see the [strip modifier](../language-modifiers/language-modifier-strip.md) instead.

# {while}
|
||||
|
||||
`{while}` loops in Smarty have much the same flexibility as PHP
|
||||
[while](https://www.php.net/while) statements, with a few added features for
|
||||
the template engine. Every `{while}` must be paired with a matching
|
||||
`{/while}`. All PHP conditionals and functions are recognized, such as
|
||||
*\|\|*, *or*, *&&*, *and*, *is_array()*, etc.
|
||||
|
||||
The following is a list of recognized qualifiers, which must be
|
||||
separated from surrounding elements by spaces. Note that items listed in
|
||||
\[brackets\] are optional. PHP equivalents are shown where applicable.
|
||||
|
||||
## Qualifiers
|
||||
|
||||
| Qualifier | Alternates | Syntax Example | Meaning | PHP Equivalent |
|
||||
|--------------------|------------|----------------------|--------------------------------|--------------------|
|
||||
| == | eq | $a eq $b | equals | == |
|
||||
| != | ne, neq | $a neq $b | not equals | != |
|
||||
| > | gt | $a gt $b | greater than | > |
|
||||
| < | lt | $a lt $b | less than | < |
|
||||
| >= | gte, ge | $a ge $b | greater than or equal | >= |
|
||||
| <= | lte, le | $a le $b | less than or equal | <= |
|
||||
| === | | $a === 0 | check for identity | === |
|
||||
| ! | not | not $a | negation (unary) | ! |
|
||||
| % | mod | $a mod $b | modulo | % |
|
||||
| is \[not\] div by | | $a is not div by 4 | divisible by | $a % $b == 0 |
|
||||
| is \[not\] even | | $a is not even | \[not\] an even number (unary) | $a % 2 == 0 |
|
||||
| is \[not\] even by | | $a is not even by $b | grouping level \[not\] even | ($a / $b) % 2 == 0 |
|
||||
| is \[not\] odd | | $a is not odd | \[not\] an odd number (unary) | $a % 2 != 0 |
|
||||
| is \[not\] odd by | | $a is not odd by $b | \[not\] an odd grouping | ($a / $b) % 2 != 0 |
|
||||
|

## Examples
|
||||
```smarty
|
||||
{while $foo > 0}
|
||||
{$foo--}
|
||||
{/while}
|
||||
```
|
||||
|
