if smarty condition to select the first result

[oby1sky]

I'm trying to show the first post of the news section in a different way respect to the other posts in the news list.
My problem is that the if condition that select the first post doesn't work.
I'm trying to use the code i found here  and that i'm pasting here :
 

Example 7.37. first property example


{* show table header at first iteration *}
<table>
{foreach $items as $i}
  {if $i@first}
    <tr>
      <th>key</td>
      <th>name</td>
    </tr>
  {/if}
  <tr>
    <td>{$i@key}</td>
    <td>{$i.name}</td>
  </tr>
{/foreach}
</table>

So i went In the smartblog module, inside postcategory.tlp
In the middle has :
 

{foreach from=$postcategory item=post}
    {include file="./category_loop.tpl" postcategory=$postcategory}
{/foreach}

And then i went to the included file category_loop.tpl that i changed in this way writing an if condition with smarty
 

{if $post@ifirst}

The problem is that the if condition is skipped and isn't working:
How can i solve this problem?

Here's how I usually do something for the first item only:

{foreach from=$categories item='category' name='categories'}
    {if $smarty.foreach.categories.first}
        First item code here
    {/if}
{/foreach}

Dear NC

 

I tryed your solution writing this in postcategory.tlp
 

{foreach from=$postcategory item=post name='postcategory'}
    {include file="./category_loop.tpl" postcategory=$postcategory}
{/foreach}

 

and this in category_loop.tlp

 

{if $smarty.foreach.postcategory.first}

{/if}

But is still not working.

{foreach from=$categories item='category' name='categories'}
    {if $smarty.foreach.categories.first}
        First item code here
    {/if}
{/foreach}

I'm going to guess that you can't create a foreach loop in one TPL file and then reference it in another. Try:

{foreach from=$postcategory item=post name='postcategory'}
    {include file="./category_loop.tpl" postcategory=$postcategory first=$smarty.foreach.postcategory.first}
{/foreach}

Then you can use {$first} in category_loop.tpl.

Thank you very much, this was the answer to my problem
