{\$var=\...} {#language.function.shortform.assign}
|
|
============
|
|
|
|
This is a short-hand version of the {assign} function. You can assign
|
|
values directly to the template, or assign values to array elements too.
|
|
|
|
> **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.
|
|
|
|
The following attributes can be added to the tag:
|
|
|
|
**Attributes:**
|
|

|
|
---------------- ----------- -------- ---------- --------- -----------------------------------------------------------------------
|
|

|
|
|

nocache Assigns the variable with the \'nocache\' attribute
|
|
|
|
|
|
{$name='Bob'}
|
|
|
|
The value of $name is {$name}.
|
|
|
|
|
|
|
|
The above example will output:
|
|
|
|
|
|
The value of $name is Bob.
|
|
|
|
|
|
|
|
|
|
{$running_total=$running_total+$some_array[row].some_value}
|
|
|
|
|
|
|
|
|
|
{$user.name="Bob"}
|
|
|
|
|
|
|
|
|
|
{$user.name.first="Bob"}
|
|
|
|
|
|
|
|
|
|
{$users[]="Bob"}
|
|
|
|
|
|
|
|
Variables assigned in the included template will be seen in the
|
|
including template.
|
|
|
|
|
|
{include file="sub_template.tpl"}
|
|
...
|
|
{* display variable assigned in sub_template *}
|
|
{$foo}<br>
|
|
...
|
|
|
|
|
|
|
|

|
|
|
|
|
|
...
|
|
{* foo will be known also in the including template *}
|
|
{$foo="something" scope=parent}
|
|
{* bar is assigned only local in the including template *}
|
|
{$bar="value"}
|
