Redirect not logged in users if they are on a specific page and category

Question

Following code is working fine for pages but how to add category id as well with pages in the following code.

add_action( 'template_redirect', function() {

  if ( is_user_logged_in() || ! is_page() ) return;

  $restricted = array( 250, 253 ); // all your restricted pages

  if ( in_array( get_queried_object_id(), $restricted ) ) {
    wp_redirect( site_url( '/user-registration' ) ); 
    exit();
  }

});

Answer 1

In you actual code you can see this:

if ( is_user_logged_in() || ! is_page() ) return;

This code does this: if user is logged in or is not in a page, then return/do nothing. You need to remove ! is_page():

add_action( 'template_redirect', function() {

    if ( is_user_logged_in() ) return;

    $restricted = array( 250, 253 ); // all your restricted pages

    if ( in_array( get_queried_object_id(), $restricted ) ) {
        wp_redirect( site_url( '/user-registration' ) ); 
        exit();
    }

});

Alternatively you can leave is_page() and add also the check for is_category() as your needs.
