WordPress how to give access to a page only for subscribers

Question

I am trying to give access of the specific page just for my subscriber user role, if someone else with other then subscriber role or non role user want to access to this page redirect them to a custom login page, I tried with below snippet but I think something is wrong with it, can you please help me to fix this

Example : Restrict access to specific pages

add_action( 'template_redirect', function() {

    // Get global post
    global $post;

    // Prevent access to page with ID 1052
    $page_id = 1052;
    if ( is_page() && ( $post->post_parent == $page_id || is_page( $page_id ) ) ) {

        // Set redirect to true by default
        $redirect = true;

        // If logged in do not redirect
        // You can/should place additional checks here based on user roles or user meta
        if ( current_user_can( 'subscriber' ) || !is_user_logged_in()) {
            $redirect = false;
        }

        // Redirect people without access to login page
        if ( $redirect ) {
            wp_redirect( get_site_url().'/custom-url-login' ); exit;
        }


    }

} );

You could refactor your code like this:

add_action( 'template_redirect', 'checking_current_user' );

function checking_current_user() 
{

  global $post;

  global $current_user;
  
  $page_id = 1052;

  if ( 
      ( $post->post_parent == $page_id || is_page( $page_id ) )
      &&  
      ( !in_array('subscriber', $current_user->roles) )
     ) 
  {
    wp_safe_redirect( site_url('/custom-url-login') );
    exit;
  }
  
}

This answer has been tested and works fine!

Wouldn't this do what you asked for?

// If user role 'subscriber' & logged in do not redirect
    // You can/should place additional checks here based on user roles or user meta
    if ( current_user_can( 'subscriber' ) && is_user_logged_in()) {
        $redirect = false;
    }

First of all you must need to check user is logged-in or not, If user is not logged-in then you need to redirect user to login page, After to login you need to apply code code then it will work fine.

add_action( 'template_redirect', 'check_current_user' );
function check_current_user(){
 global $post, $current_user;
$page_id = 1052;
if ( is_page() && ( $post->post_parent == $page_id || is_page( $page_id ) ) ) {
   if ( is_user_logged_in() ) {
      /*==Now check user is subscriber==*/
      $current_user = wp_get_current_user();
      $role = $current_user->roles;
      $currentRole = $role[0];
      if($currentRole == "subscriber"){
         $redirect = false;
      }else{
         $redirect = true;
      }
  }else{
     wp_safe_redirect( site_url('/custom-url-login') );
  }
 }
}
