Redirect guest if he tries to access a specific page

Question

While I'm developing a website and doing some testing I would like to block access to non-admin (and eventually non-editors) to specific pages such as the woocommerce shop and related pages.

Is there a way, without using plugins, in the functions.php to check:

$list_of_blocked_pages = [ 'shop', 'cart', 'checkout', 'etc...' ];

if ( current_page_is_in( $list_of_blocked_pages ) && !admin && !editor ) {
    redirect_to_page( $url );
}

Answer 1

You can use template_redirect action to redirect Specific users based on your terms. This action hook executes just before WordPress determines which template page to load. It is a good hook to use if you need to do a redirect with full knowledge of the content that has been queried.

You can use is_page function to check weather the current page is in your list of pages or not.

add_action( 'template_redirect', 'redirect_to_specific_page' );

function redirect_to_specific_page() {
    if ( is_page('slug') && ! is_user_logged_in() ) {
        wp_redirect( 'http://www.example.dev/your-page/', 301 ); 
        exit;
    }
}

Answer 2

I ended up solving like this:

function block_woocommerce_pages_for_guest() {
    $blocked_pages =  is_woocommerce() || is_shop() || is_cart() || is_checkout() || is_account_page() || is_wc_endpoint_url();
    if( !current_user_can('administrator') && !current_user_can('editor') && $blocked_pages ) {
        wp_redirect('/');
        exit;
    } 
}
add_action( 'wp', 'block_woocommerce_pages_for_guest', 8 );

This way all non-admin and non-editor will be redirected to the homepage.
