Hi,

i'm new with Smarty and i try to do something basic with a foreach loop.

I'll try to add a custom counter in the loop but that don't work ...

Here is my code :

Code:

{counter start=1 skip=1 print=false assign=count}
{foreach from=$new_products item='product' name='newProducts'}
// Do somthing

//Here i want to increment {$count} if it's lower than 3 or set to 1 if higher than 3

{/foreach}


Can u help me ?

You can make use of the @iteration property. See http://www.smarty.net/docs/en/language.function.foreach.tpl

Code:
{foreach from=$new_products item='product' name='newProducts'}
// Do somthing

//Here i want to increment {$count} if it's lower than 3 or set to 1 if higher than 3
{if $product@iteration <= 3}{$count =  $product@iteration}{else}{$count = 1}{/if}

{/foreach}

You probably don't need to create this counter. As Uwe says, the index and iteration are both available in the loop. To do something every 3rd iteration you can do:

Code:
{if $smarty.foreach.newProducts.iteration is div by 3}
  ...
{/if}

Ok thanks so, what do you think about the code below ?

This code work fine and he write an html table with 4 products by line but, if the number of products is not div by 4 (EX :5 products), it write 3 empty <td> before closing the current <tr> and stop the loop.

Code:

   {$productByLine = 4}
   {$productLineTurn = 1}
   {$tr = true}
   {$turns = 1}
   
   <table style="border: 1px solid #CCC;">
      {foreach from=$products item=product name=products}
         
         <!-- Start a new line -->
         {if $tr}
            <tr>
            {$productLineTurn = 1}
            {$tr = false}
         {/if}
         
         <td style="padding: 5px; border: 1px solid #CCC;">
            {$productLineTurn} - {$product.name}
         </td>
         
         <!-- In end of products array -->
         {if $smarty.foreach.products.iteration == $products|@count}
            
            {section name=boucle start=0 loop=$productByLine-$productLineTurn step=1}
               <td style="padding: 5px; border: 1px solid #CCC; text-align: center; color: #AAA;">Empty</td>
            {/section}
            
         {/if}
         
         {if $smarty.foreach.products.iteration is div by 4}
            </tr>
            {$tr = true}
         {/if}
      
         {$productLineTurn = $productLineTurn+1}
         {$turns = $turns+1}
         
      {/foreach}
   </table>


Thx

it would be easier to do this:

Code:
<tr>
  {foreach ...}
      {if ... is div by 4}</tr><tr>{/if}
  {/foreach}
</tr>


This starts a new table row every 4 elements.
