Simple Extension and $wgOut->addScript - MediaWiki-l

15 Sep 2009


      Hi,
I'm working on what I think is a relatively simple extension to insert some javascript and css links into the head element of a particular page.  I'm pretty new to MediaWiki so I'm sure that I'm just missing something here.  Anyway, in the code below, the extjsHead method is my preferred method of inserting the links within the head tags in my page.  However, nothing is ever inserted in the head tag when I use $wgOut->addScript(...).  The only way I've found to do this is to use the extjsBody method to insert the script tags within the body of my page.
Am I just missing something or is it not possible to use $wgOut->addScript in this manner?
