How can I increment a Smarty variable?

Question

I am not usually a Smarty guy, so I\'m a bit stuck.

I want to echo the index of an array, but I want to increment it each time I echo it.

This is what I have...<

You can do something like the following:

    {foreach from=$gallery key=index item=image name=count}
    

        
    
    {/foreach}

Starting from zero, index is the current array index.

That's probably the best way to go about it, however, to simply use a counter outside of a foreach loop you can use counter, like so:

{counter start=0 skip=1 assign="count"}

To increment it simply call {counter} at each iteration.

{counter}
{*Can then use the $count var*}
   {if $count is div by 4}
      {*do stuff*}
   {/if}
