php code not executing after calling a javascript alert

Question

I'm having some troubles getting a php redirect to execute after a javascript alert is called. The code is below:

echo '<script>window.alert("This device is aleady registered to another user");</script>';
header('Location: page.php');

After clicking "OK" on the alert, the redirect does not execute. Any thoughts as to how I can get this code working?

Thanks

Answer 1

You can't send headers after your output. Just redirect the user thru javascript all the way instead.

echo '<script>window.location.href = "page.php";</script>';

Answer 2

You can't output anything before calling header , not even a single space. You can use header before outputting the script like in the code below

header('Location: page.php');
echo '<script>window.alert("This device is aleady registered to another user");</script>';

Hope this helps you

This is the best you can do use :-

window.location
