Posting to another/external PHP

Hi,
I’ve been searching and haven’t been able to figure it out or find it. I’m trying to use a control or form to get user input and send it to a 3rd party PHP. It can go as a GET or POST doesn’t matter. Can someone point me in the right direction?

Look at the PHP Curl extension. You can send and receive data as post/get etc.

All of that I have, I’m just not sure of where to plug it in on my form.

Still trying to figure out the proper place to put the code? Would it be under Validations or where?

It - as always - depends. You can add the code to a button, if you store the request then you can use onbefore/after insert/update. Onvalidate can be suitable. It really is hard to advise without more info.
