不，不正确-get_user_meta() 返回基于$user_id 您提供的参数。您可以将其与get_current_user_id() 检查用户是否已登录，如果已登录，则获取post meta。E、 g.这样：

$curr_user_id = get_current_user_id();
// the value is 0 if the user isn\'t logged-in
if ( $curr_user_id != 0 ) {
    // we know now the user is logged-in, so we can use his/her ID to get the user meta
    $um_value = get_user_meta( $curr_user_id, \'your-key\', true );
    // now we check if the value is correct
    if ( ! empty( $um_value ) && $um_value == \'your-value\' ) {
        // if so we can output something
        echo \'user meta has the value\';
    }
}
