pull a variable from the link

[Abe1]

How can i get a link that says *.*.php&f=12 to make $forumid = 12 in the called PHP?

[rake]

vBulletin does it for you. Take a look in the includes/init.php file. It translates short variable names to long names. In this case $f => $forumid.

It looks like I was using php&f=5 I just relized it should be php?f=5.

Correct?

[rake]

Yes, that is correct.

Yes, that is correct.
I realized what I was doing wrong. I was using a form and didn't have a hidden field called forumid. I was doing the ? the right way.
