[Solved] smarty variables inheritence and scope in tpl

I'm trying to update a variable inside an include file, but it seems the variable only lives inside the incuded tpl. using PS1.5.5

 

here's what I've done:

1. in product.tpl:

{$id_cms=""}
.
.
.
{include file="$tpl_dir./assign_cms_page.tpl" id_cms=$id_cms}

<a href="{$link->getCMSLink($id_cms)|escape:'html'}?content_only=1" class="iframe">
<img src="{$img_dir}bg/help.jpg" alt="help" />
</a>

2. in the included file:

{if {$id_attribute_group|intval}==4}
	{$id_cms=6}
{else}
	{$id_cms=50}
{/if}

Why isn't the $id_cms variable inside the included file update the external variable?

ok, you learn something new every day....

 

according to the smarty tutorial :

 

  • You can use all variables from the including template inside the included template. But changes to variables or new created variables inside the included template have local scope and are not visible inside the including template after the {include} statement. This default behaviour can be changed for all variables assigned in the included template by using the scope attribute at the{include} statement or for individual variables by using the scope attribute at the {assign} statement. The later is useful to return values from the included template to the including template.

 

So I resolved the problem by modifying the calling line like this (got some help from stackoverflow ):

{include file="$tpl_dir./assign_cms_page.tpl" scope="parent"}
