How to access and loop over inner array elements in smarty. I mean the elements of arrays having index 1,2,3,... Also please explain me how to access the inner elements of inner arrays itself(i.e.[applicable_states], [product_id_N]). Thanks in advance.

Answer 1

Check for an int and than loop again.

PHP

foreach($array as $key => $innerArray) {
    if(is_int($key)) {
       foreach($innerArray as $innerKey => $innerValue) {
           echo $innerValue['applicable_states'];
       }
    }
}

Try this for Smarty:

{foreach from=$array key=key item=innerArray}
  {if is_int($key)}
     {foreach from=$innerArray key=innerKey item=innerValue}
        {$innerValue.applicable_states}
     {/foreach}
  {/if}
{/foreach}
