Wordpress - Restrict page by user role - URL Redirect

I am trying to restrict a page for all user roles except "librarian"

I've got a library dashboard on example.com/library-dashboard

When a loogged in user role that is not 'librarian' visits this page, I need to redirect them to example.com/subscription-needed

I am using the following function for this:

function is_corr_user($page_slug) {

  // User has to be logged in
  if(!is_user_logged_in())
    return false;

  // All user roles
  $roles = wp_get_current_user()->roles;

  // For each page check if user has required role
  switch($page_slug) {
    case "library-dashboard":
     return in_array('librarian, administrator', $roles);
    default:
      return false;
  }
}


// Hook to wordpress before load and check if correct user is on page
add_action( 'wp', 'wpse69369_is_correct_user' );
function wpse69369_is_correct_user()
{
    global $post;

    // Redirect to a custom page if wrong user
    if(!is_corr_user($post->post_name)) {
      wp_redirect( '/subscription-needed/' );
      exit;
    }     
}

My issue is that this function now redirects all pages to example.com/subscription-needed/ including the homepage and I am getting too many redirects error.

How can I fix this, so the function only works for the given user role librarian on the page example.com/library-dashboard ?

So what I'm trying to achieve is that if librarian & administrator visits example.com/library-dashboard then nothing happens and the page shows as normal.

But If any other user role that is NOT librarian & administrator visits the page example.com/library-dashboard, they should be redirected to example.com/subscription-needed/

I think in line #28/#26, you should use is_corr_user() and not is_correct_user().. - Sally CJ
You're absolutelly right! The fatal error is gone, but another issue just came up. - Joe Bloggs
For some reason my homepage is now redirecting to the /subscription-needed/ page. Why is that? - Joe Bloggs
Yes this is how it works why because you haven't specified any particular page and hence it works for all page including homepage - Vignesh Pichamani
@JoeBloggs please edit your question as you found the solution for this question (Fatal error problem) but seems that you ask different problem - Vignesh Pichamani

This worked for me, which you can use in place of both the is_corr_user() and wpse69369_is_correct_user() functions:

add_action( 'template_redirect', 'librarian_dashboard_redirect' );
function librarian_dashboard_redirect() {
    if ( is_user_logged_in() && is_page( 'library-dashboard' ) ) {
        $user = wp_get_current_user();
        $valid_roles = [ 'administrator', 'librarian' ];

        $the_roles = array_intersect( $valid_roles, $user->roles );

        // The current user does not have any of the 'valid' roles.
        if ( empty( $the_roles ) ) {
            wp_redirect( home_url( '/subscription-needed/' ) );
            exit;
        }
    }
}

Check with below code.

add_action('wp', 'redirectUserOnrole');
function redirectUserOnrole() {
 //First i am checking user logged in or not
 if (is_user_logged_in()) {
    $user = wp_get_current_user();
    $role = (array) $user->roles;
    //checking for the user role you need to change the role only if you wish
    if ($role[0] != 'librarian' || $role[0] != 'administrator') {
        global $post;
        if ($post->post_name == 'library-dashboard') {
            wp_redirect('/subscription-needed/');
            exit;
        }
    }
 } else {
    return true;
 }
}
