Topic on Project:Support desk

I'm trying to override the text inside the <title> tag for certain pages, specifically on the upload Special:Upload pages with the value specified in the wpDestFile url paramter. Is this possible and if so what hook would I use? I was thinking I might be able to use BeforePageDisplay but I don't think that allows me to modify content in the head.

Are you using $out->setHTMLTitle()?

Im pretty sure beforePageDisplay is the correct hook.

Thank you very much, that was the hook. I have the hardest time understanding function documentation page and often rely too much on the manual in MediaWiki for the hook.
