[Resolved] Cannot modify header information error with hook to check is_user_logged_in()

[Jessica]

Hi,

I wanted to check if the user is logged into WordPress before showing a page. If user is logged in, redirect to page A, if not, redirect to page B.

Added a hook to wp_head with the following PHP code but I got an error that the header information cannot be modified…

<?php 
  if (is_user_logged_in()) {
  header("Location: http://www.youtube.com");
} else {
	header("Location: http://www.google.com"); 
}
?>

Got the following error code:
Warning: Cannot modify header information – headers already sent by (output started at /homepages/XXX/wp-content/themes/generatepress/header.php:12) in /homepages/XXX/wp-content/plugins/gp-premium/elements/class-hooks.php(215) : eval()’d code on line 5

Any help to get over this error is greatly appreciated!
Thanks!

Hello Jessica,

Sorry, but this isn’t something a theme (any themes) would handle. I found this thread which may help: https://stackoverflow.com/questions/25918168/wordpress-redirect-when-user-is-logged-in-on-login-page#:~:text=All-,answer,-here%20did%20not

It would also be good to reach out to WordPress’ support team with regards to this: https://wordpress.stackexchange.com/
