Question

So i am using ajax request to submit a form through a link. However, when I want to receive inputs in my php, I don’t know how to do so. For instance, I normally do this

if($_SERVER["REQUEST_METHOD"]=="POST&&isset($_REQUEST["register"]))
  {
    //do stuf here
  }

But now when the ajax has submitted the code, how can I check form submission. I don’t even have the register (input type submit). Whenever, I do so the error message shows `No such index” for form inputs that are inside there.

Note that you can always check if the current request is an AJAX:

if (isset($_SERVER['HTTP_X_REQUESTED_WITH']) && $_SERVER['HTTP_X_REQUESTED_WITH'] === 'XMLHttpRequest')
{
    // This is an AJAX request, proccess the data from $_POST, $_GET or $_REQUEST
}
