Change the user role after x days

Question

Is there a way to change back the user role after x days? When people register at my site, they have an 2 options to choose: seller or customer. I want to put an additional user role member1, and if I make them user role member1, after 14 days the user role should automatically change back to their default user role (either seller or customer). Is this possible?

Here is an idea that you can implement. I think it will work just fine.

1. Save the expiration time in user meta. Say the meta name is change_role. What you save in the meta is unix time. If you want to change them back in 14 days. Set the meta value to time() + 60 * 60 * 24 *14

code example update_user_meta($user_id, 'change_role', time() + 60 * 60 * 24 *14);

2. Register a wp cron to search for expired accounts and change their roles back. Run the cron every hour or so. The search query will search for users who have the change_role meta value less then the current unix timestamp value.

Code Example

The cron function may look like this.

function change_expired_users_role(){
    $args = array(
        'meta_key' => 'change_role',
        'meta_value' => time(),
        'meta_compare' => `<=`,
        'fields' => array('ID')
    );

    $users = get_users($args);

    if(empty($users))
        return;

    foreach($users as $user){
       // change user role
       // delete the user meta
    }
}

Hope this helps.
