Redirect a logged in user from a landing page

This redirect is not working for me.
I am trying to add a redirect once user has successfully logged in.
Keeps staying on original Login page.

Test login: ToniMills pswd: EIaGg9giEMdq

Follows content of Child functions.php (I removed the opening php tag in case it messed up the form submit). What am I missing? Thanks

Hi Chad

I tried to use this one (by pasting the code snippet into functions.php of the child theme and changing the links as per below), but got the following error message when trying to test it on the relevant page:

Warning: Cannot modify header information – headers already sent by (output started at /Applications/XAMPP/xamppfiles/htdocs/wordpress/wp-content/themes/Divi/header.php:4) in /Applications/XAMPP/xamppfiles/htdocs/wordpress/wp-includes/pluggable.php on line 1121

Is there a conflict with my theme?

Here’s the code I use:

//redirect "Medlemskab" when logged in

add_action( 'wp_head', 'check_page' );
function check_page()
{
	/**
	 * If the page is the landing page AND the user is
	 * logged in, then use wp_redirect to send the user
	 * to some URL (presumeably the main site).
 	 */
	if( is_page( 'medlemskab' ) && is_user_logged_in() ) {
		wp_redirect( 'http://localhost/wordpress/medlem-velkomst' );
		exit();
	}

	return;
};

Thanks!
