Hi,

I'm trying to create a variable inside a template (banners_count) and
it's value needs to be the number of elements of an array. I am using
this but it's not working.

{assign var=banners_count value=count($banners)}

How can it be done?

Thanks!

Nuno

Hello Nuno,

From what I understand, developers are encouraged to assign counts
beforehand, but I have found myself in the same situation as you.

You are correct that some functions like count can be used ***within if
statements*** or ***as modifiers*** if they are allowed within Smarty's
security_settings property (see
http://smarty.php.net/manual/en/vari...y.settings.php).

I use a version of the following plugin when I need a count within a
template. Use: {sizeof item=$banners assign=banners_count}

--Ken

<?php
// function.sizeof.php
function smarty_function_sizeof($params, &$smarty)
{
$mixed = $params['item'];
$assign = isset($params['assign']) ? (string)$params['assign'] : '';

if( is_array($mixed) || is_object($mixed) )
$out = count($mixed);

if( $assign )
$smarty->assign($assign,$out);
else
return $out;
}

Hello Nuno,

You can use php functions as modifiers in Smarty. Also since this is an
array you need to use the @ syntax to work on the whole array.

If you are just trying to display the count:

{$banners|@count}

If you really need to assign it to a variable for some other purpose:

{assign var="banners_count" value=$banners|@count}

Hope this s!
