Vuejs ajax call not working - php

Question

Hey Everyone so I am trying to make a vueapp that makes an ajax call to a php page. On that php page I am running a few mysql statements the most important of which is a insert statement. if that page ajax call is successful and the insert statement runs successfully I want to redirect a page. If the ajax call or the insert statement fails or the user exists I want to redirect them the same page just render the page diffrently based on the result. I've tried doing it with sessions however when i try to use the ajax error function it fires everytime even when its successful. I know this as I get an alert error. But than when it goes to the result.php page I get success. I dont understand. Any help would be great!

Heres the code for php page im making an ajax request to. (makeAccount.php)

Answer 1

this.userName doesn't exist.
You can also directly do this instead of passing by a variable :
window.location.href="successfullycreated.php?userName="+ <?php echo "'{$_GET['userName']}'";?>;

Answer 2

As long as the new page has the param present you can just get it from the URL in JavaScript.
var userName = new URL(window.location.href).searchParams.get("userName");
