如何在WordPress中获取博客的当前登录用户详细信息？

Question

当我登录到特定的多站点博客时，我试图获取当前登录用户的详细信息，我已经在下面使用了一个，但是此函数返回null。如何，我可以获得用户信息中记录的电流。其实我只是想获得用户的电子邮件

$logged_in_user = wp_get_current_user(); 
    wp_get_current_user(); is return below object with empty values 
    WP_User object { 
     back_compat_keys => array(6) ( 
        [user_firstname] => (string) first_name 
        [user_lastname] => (string) last_name 
        [user_description] => (string) description 
        [user_level] => (string) wp_user_level 
        [wp_usersettings] => (string) wp_user-settings 
        [wp_usersettingstime] => (string) wp_user-settings-time 
       ) 
     data => stdClass object 
     ID => (int) 0 
     caps => array(0) 
     cap_key => null 
     roles => array(0) 
     allcaps => array(0) 
     filter => null 
    }; 

    //email is 
    if($logged_in_user->ID != 0){ 
     $email = $logged_in_user->user_email; 
    } 

Answer 1

首先，注释掉该行：

wp_get_current_user(); is return below object with empty values 

然后，为了获取用户详细信息做到这一点：

$userID = $logged_in_user->ID; 
$userEmail = $logged_in_user->user_email; 
//and so on from there.
