I have an array that I am looping through to display my information via a foreach. I have another array that I need to match up with the records of the first array.

Can anyone offer any advice on how to reference a array at a specific location in a loop? In php, I would do a foreach and then reference the array with a incremental counter. However, I have been unsuccessfull in duplicating this in smarty.

Thanks
Chris

If the two arrays have the same keys, then it is no issue:

Code:
{foreach from=$arr1 item=i key=k}
  {$arr2.$k} {*assume like keys*}
{/foreach}


will access the related item from $arr2 as $arr1 is iterated.

If the second array must be accessed based on the ordinal given by the iteration of the first array, then you can use the iteration counter as follows (see: http://smarty.php.net/manual/en/language.function.foreach.php)

Code:
{foreach from=$arr1 item=i key=k name=test}
  {assign var=temp value=$smarty.foreach.test.iteration}
  {$arr2[$temp]}
{/foreach}


Here you must name the foreach loop so that Smarty can keep track of its properties in the builtin $smarty.foreach collection.

There are other methods, of course. If this doesn't solve it for you, perhaps describe how you are storing and relating your arrays?

HTH (but its been awhile since I posted some help, so I might be rusty)
