隐藏URL中的参数供用户查看

Question

I was just wondering if there is any possible way of getting rid of the parameters in a link. For example, I have this redirecting the user back to the original form if any errors come up:

www.mywebsite.com/form.php?error_code=1021

But I don't want the user to see the error_code=1021.

How would I code it in PHP so that after it redirect to the page with the error, it looks like this to the user:

www.mywebsite.com/form.php

Answer 1

You can take the advice in the comments and not redirect, or if you must, I would use sessions:

session_start();
$_SESSION['error_code'] = '1021';
header('Location: http://www.mywebsite.com/form.php');
exit;

Then in the form you would need session_start() and then access $_SESSION['error_code'].
