variable variables

Hi,

I would like to use variable variables in a template, and was sure to have done so before, but i can neither find the template nor can i get this running.

I have a class that consists of several elements of the same datatype (object relation), following the naming convention related_[number], where number is an int from 1 to 4.

The following code doesnt work and is only an example. What i want to archive is that [$number] gets substituted by the actual value of $number:

{def $out=array() $myobj=$node.object.data_map}
{for 0 to 4 as $number}
  {set $out = $out|append( hash( 'link', $myobj.related_[$number].content.main_node.url_alias,
'maincat', $myobj.related_[$number].content.main_node.path.1.name,
'teaser', $myobj.related_[$number].main_node.data_map.teaser.content ))}
{/for}

Any ideas would be highly appreciated!

Thanks,

Patrick

Best regards,

Patrick

At least for my original problem I found the solution in between.
Given the case you want to access attributes that follow a certain naming convention (ie. attribute_1, attribute_2, attribute_3, etc) you could do the following:

{def $attribute_pre='attribute_' $tmp=''}
{for 0 to 4 as $number}
  {set $tmp=concat( $attribute_pre, $number )}
  {$node.data_map[$tmp].content}
{/for}

Best regards,
