I need to use the method POST and GET at the same time. The "post" to submit and save the infos present on the inputs and GET to redirect the user by the other part of the code. I've read that it isn't possible, so, I thought that using JS to submit the form would be a good choice, but I don't know anything about JS, how is it possible to be done?
EDIT*
I'm want to use both (GET and POST) due the selector that contains the complement of my redirect header, take a look: header ("Location: https://mpago.la/".$_GET['qtd']);
It uses GET to take the value of the selected item, add it to the url that is set on the header and redirect the user to the final url.
I've tried to change the method on the forms to post, but it didn't work, it only redirect to the firts part of the url, but I need it to redirect to the complete url.
