Submit Form With Action=“file.php” With No Reload? [closed]

Answer 1

Are you able to use javascript + jquery? Posting asynchronously is fairly simple with jquery.

$('#formid').submit(function({ //listens for form submission

    $(this).preventDefault(); //stops the submission

    $.post('actionPage.php', $(this).serialize, function(response){
       //posts the data to actionpage.php, with the form data, and then runs a function handling the response.

    });


}));

Have the server respond with a 204 No Content response (spec).

If the client is a user agent, it SHOULD NOT change its document view from that which caused the request to be sent. This response is primarily intended to allow input for actions to take place without causing a change to the user agent's active document view

Such:

<?php
http_response_code(204);
exit();
