I need to display an array that can hold infinite number of children arrays, such as:

Code:

array(
   array(
      array()
      array()
      array()
   )
   array(
      array(
         array()
       )
      array()
   )
)


The values are irrelevent, but you could imagine values like these:
Code:

array("page_id" => 1, "page_name" => "hello world");


Ok, now you got the basics, but how do I display this array in Smarty?? Neutral

All I want to loop is the first level of the array, and I want to "call" a function/method recursively for each children array, so you can have infinite number of children arrays.

This is easy in php, I just create a function to do this, but in smarty this evades me.

HELP! Very Happy

Here is the solution if anyone is interested:

index.tpl
Code:

<ol>
{foreach from=$tree key=q item=a}
   <li>{$a.page_name}</li>

   {if sizeof($a.Childrens) > 0}
      {include file="sub.tpl" pages=$a.Childrens}
   {/if}
{/foreach}
</ol>



sub.tpl
Code:

<ol>
{foreach from=$pages key=w item=s}
   <li>{$s.page_name}</li>

   {if sizeof($s.Childrens) > 0}
      {include file="sub.tpl" pages=$s.Childrens}
   {/if}
{/foreach}
</ol>



Very simple and neat, might create an include overhead, but what doesn't!? Smile This does the job.

appel, there is a nice thread on recursion / advanced looping in the Tips & Tricks forum. Your solution is perfectly valid but you will find a much faster and possibly neater solution there Smile

Yea, thanks, that compiler.defun.php did the trick.
