foreach,foreachelse

foreach loops are an alternative to section loops. foreach is used to loop over a single associative array. The syntax for foreach is much easier than section, but as a tradeoff it can only be used for a single array. foreach tags must be paired with /foreach tags. Required parameters are from and item. The name of the foreach loop can be anything you like, made up of letters, numbers and underscores. foreach loops can be nested, and the nested foreach names must be unique from each other. The from variable (usually an array of values) determines the number of times foreach will loop. foreachelse is executed when there are no values in the from variable.

{* this example will print out all the values of the $custid array *}
{foreach from=$custid item=curr_id}
	id: {$curr_id}<br>
{/foreach}

OUTPUT:

id: 1000<br>
id: 1001<br>
id: 1002<br>

{* The key contains the key for each looped value

assignment looks like this:

$smarty->assign("contacts", array(array("phone" => "1", "fax" => "2", "cell" => "3"),
      array("phone" => "555-4444", "fax" => "555-3333", "cell" => "760-1234")));

*}

{foreach name=outer item=contact from=$contacts}
  {foreach key=key item=item from=$contact}
    {$key}: {$item}<br>
  {/foreach}
{/foreach}

OUTPUT:

phone: 1<br>
fax: 2<br>
cell: 3<br>
phone: 555-4444<br>
fax: 555-3333<br>
cell: 760-1234<br>
