Attempting to transition old php site to word press using gravity forms and need help with some of the hooks to "post" info to a .php page that carries out function. I can get the function working in word press outside of gravity forms (calling up a custom-template page) but not without exposing the url to the php. I think 'redirect' to the php will work but it does not carry the data (4 fields) with it.
So far I've identified gform_after_submission hook might be what I need but not entirely sure how to set that up based on the example.
Here's the page with the form that works but redirects to a plain page: http://pomba.ca/stage/?page_id=438 (Use seller 071 which is mine)
I will have other pages like this to transition as well. Can someone help me with these little fixes?
