我是php和web开发的新手。我为用户制作了一个前端编辑配置文件页面，每个字段都会更新，除了电子邮件（但其他所有内容都是用户元）。我在这件事上花了太长时间，但都没有用。

有很多关于这个的帖子，比如这篇How do you update user_email on the front end in WP 3.3?, 但我无法找到任何适合我的方法。我正在使用WP 4.7.3。

这是上面的帖子。它确实会更新电子邮件，但在我提交表单后，我的页面会无限期挂起：

wp_update_user( array( \'ID\' => $current_user->ID, \'user_email\' => $_POST[\'email\'] ) );

我也试过这种方法。它不会更新用户的电子邮件，也不会挂起：

$wpdb->update($wpdb->users, array(\'user_email\' => $_POST[\'email\']), array(\'ID\' => $current_user->ID));

如有任何建议，将不胜感激。我很确定问题就在于这段代码，但如果这有帮助的话，我可以包含更多的代码。

已编辑：更新用户配置文件代码。原来密码也会无限期挂起。
