Just not for me, I've done it before, but I can't remember how, basically I have a form, with say 1 text field, I want that field populated by whatever is suffixed on the URL, e.g.
http://www.blah.com/test.php?price=12345
Then, the form field should populate with 12345.
Simple eh? Just not for a plank like me, any help is as always appreciated.
Thanks.
