First block in foreach cycle - how to detect?

Which I can use for detecting output of first block (topmost) inside placeholder's cycle?

Is this for PHP, or for Smarty (templates)?

For PHP, you can use a flag:

$first_iteration = true;
foreach ($array) {
   if ($first_iteration) {
      ...
      $first_iteration = false;
   }
   ...
}


You could use the same approach in Smarty, but Smarty also has an iteration property that can be tested within the loop, so you don't need to define a separate flag.

Smarty, pure Smarty for theme. PHP isn't a problem
Now I use for (first|second|other) this snippet
<{assign var='pos' value='top'}>
<{foreach item=block from=$xoops_lblocks}>

<{if $pos == 'top'}>
   <div id="lnav1"><{$block.content}> div>
<{elseif $pos == 'second'}>
   <div id="ltn1"> <span class="title"><{$block.title}>span> div>
   <div id="lnav2"><{$block.content}>div>
<{else}>
   <div id="ltn2"> <span class="title"><{$block.title}>span> div>
   <div id="lnav2"><{$block.content}>div>
<{/if}>

<{if $pos == 'second'}>
   <{assign var='pos' value='rest'}>
<{/if}>
<{if $pos == 'top'}>
   <{assign var='pos' value='second'}>
<{/if}>

<{/foreach}>


but I hate this dirty code

    <{if $smarty.foreach.leftblocks.first}>
        <div id="lnav1"><{$block.content}> div>
    <{elseif $smarty.foreach.leftblocks.iteration == 2}>
        <div id="ltn1"> <span class="title"><{$block.title}>span> div>
