How to display three points from an array with a condition?
The code below simply displays one third item and stops (total items - 10). Items 1 and 2 are hidden because they are empty. Where is the mistake?

{|foreach from=$basketsArray key="i" item="b" name="foo"|}
{|if (!empty($b.customProduct_ssilkanatovar8))|}
{|if $smarty.foreach.foo.index < 3|}
{|$b.name|}
{|/if|}{|/if|}
{|/foreach|}

If you want to output items from array by 3, the easy way is to split array into chunks first.
Try something like
Code:
{foreach array_chunk($basketsArray, 3, true) as $foo}
  // Print chunk decoration
  {foreach $foo as $i => $b}
    // print elements from a chunk
  {/foreach}
{/foreach}
