Patrick Kaiser	Thursday 30 March 2006 8:33:25 am 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

So that I can access i.e. $myvariable later on the page. But there seems to be no option to do this with variables in EZ. It even surprises me more that I seem to be one of the few who would need this? Jesper
Patrick Kaiser	Tuesday 07 August 2007 12:32:37 pm 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, Patrick

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
