I've been trying to accomplish something I thought would be very simple but for some reason I have just a brick wall.
Basically I have a form that when it loads needs to have a hidden field dynamically populated. The form is loaded from a hyperlink on a post page so I want to pass the post ID to the form via the Query String. I have been through all your documentation and every forum post I can find, including those posted by your admins pointing to a discussion that apparently answers this sort of question, but I just can't get anywhere!
I can easily pass text dynamically into the field via the query string but I can't get the post id to dynamically render. The merge tags don't work (I'm assuming because they only function on submitting a form) and php code doesn't seem to work.
Please PLEASE can someone help me with this!
