How do I post to URL

Hi,

I have been looking at the Deluge scription reference as well as the tips and tricks and theforums however I am unable to finad a solution to my problem.

I have a form for example with 3 field A, B and C. I need to Post this data to an external PHP script to be recieved as a POST, processed and possibly returned to update the form or another form.

I would like to know how this may be achieved. From my understanding the postUrl function requests variable from an external applications. I had tried this initially however I do not understand what the map variables were for and the status message. It appears that this is for only retrieving information. Please correct me if I am wrong.

With the API from my understanding, I can only use the API to send Information back from an external application.

How do Post the form data during the onsubmit or onclick script.

I really need this urgently and a response would be highly appreciated

Regards
Mobz
