This tag reads arrays. Between the {loop} tag the following tags have special value:
- {$key}, return the selected key.
- {$value}, return the selected value. To access associative array you can use for example {$value.name}.
- {$counter}, return the loop counter, which starts from 0. {$counter+1} start from 1, {$counter%2} will iterate values 1,0.
Example
// user_list = array( array('name'=>'Mars'), array('name'=>'Jupiter') ... )
{loop="user_list"}
{$key} - {$value.name}</br>
{/loop}
{loop="user_list"}
{$key} - {$value.name}</br>
{/loop}
Output
0 - Mars
1 - Jupiter
2 - Earth
1 - Jupiter
2 - Earth
{loop="array"}{else}{/loop}
You can use {else} tag to output a message when the array is empty.
Example
// user_list = array()
{loop="user_list"}
{$key} - {$value.name}</br>
{else}
User List is empty
{/loop}
{loop="user_list"}
{$key} - {$value.name}</br>
{else}
User List is empty
{/loop}
Output
User List is empty
