    What if you would like to send some get/post information back to the PHP files? I have tried to add method:’GET’ to the form and also add some hidden items with values but the $_GET on the php side never detects that they have been sent.

      GET won’t work with forms but POST is no problem. Just add your hidden fields with values to the generated form and check $_POST variable in PHP.

    Hi Saki,

    Could you please suggest me to get the failure response of form submit?

    I need to capture failure response and show it as a message alert for users. Thanks for your time.


We will be happy to hear back from you
