Redirect to specific page if not logged in WordPress

Question

I am trying to have it on my WordPress site to redirect to a landing page if the user is not logged in, but it always gets stuck in a redirect loop. This is basically what I have (in functions.php)...

    add_action( 'template_redirect', function() {

        if ( !is_user_logged_in() && ! is_page('login-to-view') ){
            wp_redirect( site_url( '/login-to-view' ) );
            exit();
        }

     });

Solution

The issue is that I had the function in functions.php. is_page didn't know what page it is on yet. I moved it to the header, just before the doctype declaration and it works now with just this...

if ( ! is_page('login-to-view')  &&  ! is_user_logged_in() ){
    wp_redirect( site_url( '/login-to-view' ) );
    exit();
}

Another thing to note... I wasn't able to get it to work on my localhost, I'm thinking because site_url can't be found, and it was just redirecting to localhost:8888/login-to-view

I'm using MAMP, but I'm guessing you can set up URL paths like that in the PRO version.

Check if is_page('login-to-view') gives the expected result. Comment out the if block, and do something like if ( is_page('login-to-view') ){echo '<script>alert("This is the page!")</script>';} . Go visit some pages and see if this is working as it should. Especially on your 'login-to-view' page
