Question

How can I limit the amount of loops through an array using Smarty? Let’s say that there’s 32 items in a given array, I’d like to limit the number of loops to 8.

{foreach from=$friend_list key=userId item=userInfo name=friend_list}
    {if $smarty.foreach.friend_list.index % 8 && $smarty.foreach.friend_list.index > 0 }
        </tr><tr>
    {/if}
        <td height='50' width='50'>
            <img border='0' height='50' src='http://graph.facebook.com/{$userInfo.user_uid}/picture' style='display:block;' width='50' />
        </td>
{/foreach}

Thanks

{foreach from=$friend_list key=userId item=userInfo name=friend_list}
  {if $smarty.foreach.friend_list.index < 8 }
    {if $smarty.foreach.friend_list.index % 8 && $smarty.foreach.friend_list.index > 0 }
        </tr><tr>
    {/if}
        <td height='50' width='50'>
            <img border='0' height='50' src='http://graph.facebook.com/{$userInfo.user_uid}/picture' style='display:block;' width='50' />
        </td>
  {/if}
{/foreach}

Read this Smarty – foreach loop 10 times and stop

ps: I intentionally left the if block with if $smarty.foreach.friend_list.index % 8 in case if will need more than 8 loops. Otherwise that block could be removed (keeping </tr><tr> intact)
