Also note that the id $_GET parameter is reserved (for now) in MODx, as that is used to tell the parser what document you are requesting. q is another $_GET parameter that should be avoided for the time being as well. Otherwise, you can pass and use $_REQUEST variables in MODx snippets as you normally would in a PHP script.
Thank you very much. It was the first time I have posted a topic and really amaze by your great answer.
I am going to try it right now.

That’s not at all what I just said. I said using $_GET[’id’] or $_GET[’q’] is bad, as is $_POST[’id’] or $_POST[’q’] -- using $_GET and $_POST in general is fine.
Alright, I will not use $_GET.
Another thing is: Where shall I put the code of beforeFormParseFunction? I guess it could go just before the eform snippet call. Is this the right place?
