Tag {var}
|
|
=========
|
|
|
|
The tag {var} is used for assigning template variables during the execution of a template.
|
|
|
|
```smarty
|
|
{var $var=EXPR}
|
|
```
|
|
|
|
```smarty
|
|
{var $var}
|
|
... any content ...
|
|
{/var}
|
|
```
|
|
|
|
```smarty
|
|
{var $var|modifiers}
|
|
... any content ...
|
|
{/var}
|
|
```
|
|
|
|
Variable names follow the same rules as other labels in PHP.
|
|
A valid variable name starts with a letter or underscore, followed by any number of letters, numbers, or underscores.
|
|
|
|
```smarty
|
|
{var $v = 5}
|
|
{var $v = "value"}
|
|
|
|
{var $v = $x+$y}
|
|
{var $v = 4}
|
|
{var $v = $z++ + 1}
|
|
{var $v = --$z}
|
|
{var $v = $y/$x}
|
|
{var $v = $y-$x}
|
|
{var $v = $y*$x-2}
|
|
{var $v = ($y^$x)+7}
|
|
```
|
|
|
|
Creating array
|
|
|
|
```smarty
|
|
{var $v = [1,2,3]}
|
|
{var $v = []}
|
|
{var $v = ["one"|upper => 1, 4 => $x, "three" => 3]}
|
|
{var $v = ["key1" => $y*$x-2, "key2" => ["z" => $z]]}
|
|
```
|
|
|
|
Getting function result into variable
|
|
|
|
```smarty
|
|
{var $v = count([1,2,3])+7}
|
|
```
|
|
|
|
Collect the output of the template into a variable
|
|
|
|
```smarty
|
|
{var $v}
|
|
Some long {$text|trim}
|
|
{/var}
|
|
|
|
{var $v|escape} {* apply modifier to variable*}
|
|
Some long {$text|trim}
|
|
{/var}
|
|
```
