Recursive Function inside Smarty.tpl

Question

Can someone help me to translate this code into smart friendly, taken from Here

function outputCategories($categories, $startingLevel = 0)  
{

    foreach ($categories as $key => $category)
    { 
        if (count($category['children']) > 0)
        {
            echo '<li><a title="'.$category['name'].'" href="'.$category['url'].'">'.$category['name'].'</a><ul>';
            outputCategories($category['children'], $startingLevel+1);
            echo "</li>";
        }
        else
        {
            echo '<li><a title="'.$category['name'].'" href="'.$category['url'].'">'.$category['name'].'</a></li>';
        }
    }
    echo "</ul>";
    return self;
}

I'm able to generate single level categories using this lines:

{foreach from=$hsitemap item=c name=hsitemap}
 {if $c.parent_id ==0 }
<li><h2><a title="{$c.site_name}" href="{$c.site_url}">{$c.site_name}</a></h2><ul>
    {foreach item=d from=$c.children name=sitemap} 
<li><a title="{$d.site_name}" href="{$d.site_url}">{$d.site_name}</a></li>
    {/foreach}
{else}  
<li><h2><a title="{$c.site_name}" href="{$c.site_url}">{$c.site_name}</a></h2><ul>
{/if}
</ul>
</li>
{/foreach}  
</ul>

But now I have a requirement for multilevel, kindly help me with this.

you should make an include-file which includes itself every new level... nest the loop to a new file or create a smarty-function, then include it or call the smarty-function, and IN IT, call itself (or call the function)...

Hmmm, including smarty function inside smarty..never done that...ll search for some examples.. – lonelycrypto Aug 23 '12 at 06:07
It's a silly solution. In smarty you can create functions: http://www.smarty.net/docs/en/language.function.function.tpl – uzsolt Aug 23 '12 at 10:13
as i said... recursion with includes OR function if you have php-access to the layer -- – TheHe Aug 23 '12 at 10:29
Sorry, I was careless. But the "recursive" including is silly solution. Does it have any advantage? – uzsolt Aug 23 '12 at 19:12
4sure it doesn't... but, as i thought he didn't know, that you can define functions... maybe he could be a designer who doesn't have access to the php-core of the system and cannot define new funtions... smarty-template-recursion is not the best, but is easy understandable and will work. – TheHe Aug 23 '12 at 19:50

You can create functions which can call itself, see example 7.43. in documentation.

Thank you, I'm aware of it.. The problem I'm facing now is that I'm unable to call the function inside {block name="content"}, which shows a blank page.. – lonelycrypto Aug 27 '12 at 06:50
