我有一个自定义插件，可以根据保存的搜索功能发送电子邮件。当我输入一封特定的电子邮件时，该功能似乎起作用，但在浏览个人资料时却不起作用。

代码如下：

function saved_search_send_event_hook($timeslot = \'onceaday\') {
    $blogname = get_bloginfo();
    global $wpdb;
    $users = $wpdb->get_results( "SELECT * FROM $wpdb->users AS u
        LEFT JOIN wp_m_membership_relationships AS mmr ON mmr.user_id = u.id
        LEFT JOIN wp_m_subscriptions AS s ON mmr.sub_id = s.id
        WHERE s.sub_name = \'AnActiveWithMembership\'" );
    foreach($users as $user) {
        $profiles = erns_saved_search_getprofiles($user->ID, $timeslot);
        if(!empty($profiles[\'count\'])) {
            // The code works with \'[email protected]\' on this line instead of $user->email
            $to = $user->email; 
            $subject = \'[\' . $blogname . \'] \' . trim(\'Saved Searches\');
        }
    } 
}

我觉得我忽视了这里的一些东西。如果您需要任何其他信息，请告诉我。Wordpress v4。1.
