Working with arrays recursively

[Christoph Boget-2]

I know you can set up nested {foreach} blocks in the template but that only
works if you know that the array you are working with has a predefined
number of levels.  Is there a way to set up a block so that you can work
with the array recursively?  So no matter how many levels the array has,
your smarty block can handle and display all the data?

thnx,
Christoph

parameters can be assigned to the include file using {include} to avoid
overwriting--example below. - ken


main.tpl:

{include file="recurse.tpl" parents=$tree level=0}


recurse.tpl

{foreach from=$parents item=child}
  {$child.name}
  {if $child.children}
    {include file="recurse.tpl" parents=$child.children level=$level+1}
  {/if}
{/if}
