Code:


Array ( [Automotive] => Array ( [0] => Array ( [sub_id] => [cat_id] => 37 [sub_name] => ) ) [Business] => Array ( [0] => Array ( [sub_id] => 27 [cat_id] => 51 [sub_name] => Services ) )



I have a bunch of data setup in this format, I'm currently using the foreach statement below to go through it
Code:


{foreach from=$categories key='cat_name' item='category'}

 {$cat_name}:
  {foreach from=$category item='sub_category'}
      {$sub_category.sub_name}
  {/foreach}

{/foreach}




Does anyone know how I would loop through this using section instead of foreach?

You can't and why would you want to? Section tags require 0-based indexed arrays -- yours is associative.

I want to display the data in 3x columns, I can't seem to figure out how I would do that with foreach.

Yeah, I kinda got that based on your other posts Smile Okay, I know that you know this thread: http://www.phpinsider.com/smarty-forum/viewtopic.php?t=1391 you can adapt that method by using the iteration property on the foreach loop (don't forget to name the foreach loop).

Boots, I've looked at the thread but and I tried one option that seemed like it might work, where I had section tags within the first foreach, but it did not work and I was not using the iteration.. I'm really not sure what to do. I appreciate your help!

Got it to work, for the record this is what I did

Code:

{foreach from=$categories key='cat_name' item='category' name='cats'}



{if $smarty.foreach.cats.iteration % 3 == 1}
<td>
    {$cat_name}:
    {foreach from=$category item='sub_category'}
         {$sub_category.sub_name}
        {/foreach}
</td>
{/if}

{if $smarty.foreach.cats.iteration % 3 == 2}
<td>
    {$cat_name}:
    {foreach from=$category item='sub_category'}
         {$sub_category.sub_name}
     {/foreach}
</td>
{/if}

{if $smarty.foreach.cats.iteration % 3 == 0}
<td>
    {$cat_name}:
    {foreach from=$category item='sub_category'}
         {$sub_category.sub_name}
     {/foreach}

</td>
</tr>
<tr>
{/if}



{/foreach}
