Smarty make counter for this type of condition

with smarty I have taken jQuery to make some texts fadein fadeout. So in smarty I want a counter value inside foreach loop.

This will count the posts and for every increment it will add class active so that it will start to show. So for now I want something like this. But I dont know how to set increment counter in smarty.

<div class="test">
{foreach from=$sliderValues item=row}
$i = 0;
while($sliderValues) {
$i++;
  if($i==1) {
    $class= 'active';
  }
  else {
    $class= '';
  }
  <div class="example '.$class.' ">something</div>
}
{/foreach}
</div>

So if someone kindly tell me how to make the smarty counter like this. Any helpa and suggestions will be really appreciable.

If you want to add class "active" to first row, you can use just this code. Without additional i.

<div class="test">
    {foreach from=$sliderValues item='row' name='f'}
        <div class="example{if $smarty.foreach.f.first} active{/if}">something</div>
    {/foreach}
</div>

If you want/need to use i in other cases, you have to set it to 0 before foreach. In cycle you can use simply {assign var='i' value=$i+1}.

As Smarty compiles templates into PHP you actually can use bits of PHP inside of your template but it is not recommended and ugly.

What you looking for is {assign} function:

  • To assign starting value: {assign var="i" value="0"}
  • To increment: {assign var="i" value="'$i+1'"}

Then you can check variable i with standard Smarty {if $i==1}
