Show WooCommerce products only to multiple authorized user roles

问题

I'm trying to adapt "Completely hide products from unauthorized users in WooCommerce" answer code to also allow several custom user roles to view this products. I believe the best way to accomplish this is to expand the authorized user function to include this user roles.

This is the changes that I have tried to implement with no success. Can someone shine a light on how to proceed?

// Conditional function checking for authorized users

function is_authorized_user() {

    if ( is_user_logged_in() ) {

        $user = wp_get_current_user();
        $caps = $user->allcaps;

        if ( ( isset($caps['edit_product']) && $caps['edit_product'] ) ||
        array( 'custom_user_role1', 'custom_user_role2', $user->roles ) )
           return true;
    } else 
        return false;
}

How to make it work for an array of user roles, instead of just one? Any help is appreciated.

回答1:

As you have 2 arrays to compare:

• your 2 custom roles (in an array)
• the current user roles (that is an array)

you can use array_intersect() php function to make it work this way:

// Conditional function checking for authorized users
function is_authorized_user(){

    if ( is_user_logged_in() ) {

        $user = wp_get_current_user();
        $caps = $user->allcaps;

        if ( ( isset($caps['edit_product']) && $caps['edit_product'] ) || 
        array_intersect( ['custom_user_role1', 'custom_user_role2'], $user->roles ) ) {
            return true;
        }

        return false; 
    } 
    else {
        return false; 
    }
}

It should work now for multiple user roles.
