I Must Really Be Stupid...

[TCM]

... but I just cannot get the plugin thing to work.

Here's a test thing I did

Hook Location: globlal_start
Title: test code
Plugin PHP Code:

PHP Code:

global $test;

$test = "TEST!"; 


I then changed the top line of my header template to....
<!-- logo -->$test $test $test $test $test $test $test


I got nothing.

I didn't just try this. I tried different variables (including pre-defined ones), and also tried different locations. Nothing at all.

Yes, I did remember to enable it.

What's wrong with what I'm doing?

EDIT: Here's a better example.

Hook Location: global_start
Name: Prepare The Browser Message For The Footer
Code:

PHP Code:

$browser = get_browser(); 

if ($browser->parent and $browser->platform)
    $vbulletin->userinfo[browserinfo] = "You seem to be using ".$browser->parent." on ".$browser->platform.".";
elseif ($browser->parent)
    $vbulletin->userinfo[browserinfo] = "You seem to be using ".$browser->parent.".";
elseif ($browser->platform)
    $vbulletin->userinfo[browserinfo] = "You seem to be using ".$browser->platform.".";    
else
    $vbulletin->userinfo[browserinfo] = "You seem to be using a browser and an operating system. I just can't tell which ones."; 


On a side note, would that usage of "$vbulletin->userinfo" work anymore? That's not the problem, because this doesn't work even if I use something simple like $browserinfo, but it mightn't help.

EDIT: Now I'm getting even more confused. $bbuserinfo is used in templates... so where, exactly, does $vbulletin->userinfo come into the picture?

EDIT: The second example doesn't work when I use $bbuserinfo[browserinfo], but if I put "$vbulletin->userinfo" in, it does put "array" in. Or something.
