Not working for me either.
ExpressionEngine v2.1.3 - Build: 20101220
Just upgraded from 2.1.1, I think.
Trying to pass a test value from a page:
{embed="common/header" page_title="testing"}to an embed with this code:
<title>
{site_name} | {embed:page_title}
</title>Generates the following HTML code:
<title>
Get There | {embed:page_title}
</title>
For the record, I have also tried:
<title>
{site_name} | {embed=page_title}
</title>...because I found some sample code on the ‘Net that used this syntax in an earlier version of Expression Engine.
Naturally, I would like to ultimately be able to do able to actually pass the entry title to my header embed, but in the course of trying to debug the code that would set that value I discovered that I was not able to read the embed value when set simply to the string “testing”. So either I am doing something wrong or there is a bug.
