运行单独的php文件时如何访问我的URL中的$ _GET变量（不使用Session变量）

Question

I am submitting my forms using ajax to a php file that processes the form data on the server. However I need to access the variables in the URL using $_GET but I'm getting the "Undefined index:" error message. I think it's because the current URL is not included (or viewed) in the php file because I submitted it separately with AJAX. I would prefer not to use session variables in this case. Any help is appreciated.

URL ../completeAccount.php?acctnum=433462524&keyCode=bdtF5ziKWJ

Javascript

formData = $(formID).serializeArray();
$.ajax({
    url  : "process.php",
        type: 'POST',
        data : formData,
        success: function(resp) {
            //success code
        }
});

process.php

$firstname = $_POST['firstname'];
$lastname = $_POST['lastname'];
$newpass = $_POST['newpass'];
$newpass2 = $_POST['newpass2'];

$acctnum = $_GET['acctnum'];
$keyCode = $_GET['keyCode'];

//use variables to process data etc.

You should get the parameters with your javascript and append them into formData . The code that would grab a URL parameter might look like this:

function getParameterByName(name) {
    name = name.replace(/[\[]/, "\\[").replace(/[\]]/, "\\]");
    var regex = new RegExp("[\\?&]" + name + "=([^&#]*)"),
        results = regex.exec(location.search);
    return results === null ? "" : decodeURIComponent(results[1].replace(/\+/g, " "));
}

Next, just append it into formData

formData = $(formID).serializeArray();
formData.push({name: 'acctnum', value: getParameterByName('acctnum')});

Note, that acctnum will then be in POST , not in GET !
