Hey guys,

Been using Smarty for a while now, really enjoying it – but I can't figure out how to get around this.

I have a bunch of "widgets" that I want to call. They're kept in a folder.

Code:
{foreach from=$widgets item=w}
   {include file="widgets/$w.widget_id"}
{/foreach}


However, as you might have guessed, that produces an error
Severity: User Warning
Message: Smarty error: unable to read resource: "widgets/Array.widget_id"
Filename: libs/Smarty.class.php

Anybody know a better way of doing this? Or indeed, the solution?

You must use backticks.

Code:
{foreach from=$widgets item=w}
   {include file="widgets/`$w.widget_id`"}
{/foreach}


See documentation for variables in double quoted strings.
