Get BodyId value in an extension

edited February 2007 in Vanilla 1.0 Help
How would I get the contents of the BodyId variable so that I could decide what to do depending upon what page I was on? I specifically need to identify what body tag id I am on.

    $GLOBALS['Head']->BodyId ? (or directly as $Head->BodyId if you're already in the global scope)

    That's a better way than what I started to do which was to check the php page I was on and then load a variable with the body tag id. I tried the $head->BodyId but it was empty. Let me try the global reference. Thank you.

    Edit: The global reference was empty, too. What would I need to add?

    ah, dosn't look like you can without a delegate somewhere. the bodyid variable is set after the extensions are included.

    Perhaps
    function GetBodyID(&$Head) { $Head->Contex->PassThroughVars['BodyId'] = &$Head->BodyId; } $Context->AddToDelegate('Head', 'PreRender', 'GetBodyID');

    and then wherever you are, you should be able to $BodyID = &$Context->PassThroughVars['BodyID'];

    That didn't work either. So, I used the basic "if" statement that is used in each extension to tell it where to operate. I then load a variable with the body id tag for that page, e.g. index.php had a body id of DiscussionsPage. Now, my extension works and I can release it. Thank you.
