WordPress 用户管理 完全移除email邮箱 代码实例

WordPress一般情况下用户的邮箱Email字段为必填项。明升手机版记录一下在用户注册管理中，如何将email字段去除。

在functions.php中添加如下代码（ 如何方便的在更新主题时保留 functions.php 里的自定义 ）：

// This will suppress empty email errors when submitting the user form
add_action('user_profile_update_errors', 'my_user_profile_update_errors', 10, 3 );
function my_user_profile_update_errors($errors, $update, $user) {
    $errors->remove('empty_email');
}

// This will remove javascript required validation for email input
// It will also remove the '(required)' text in the label
// Works for new user, user profile and edit user forms
add_action('user_new_form', 'my_user_new_form', 10, 1);
add_action('show_user_profile', 'my_user_new_form', 10, 1);
add_action('edit_user_profile', 'my_user_new_form', 10, 1);
function my_user_new_form($form_type) {
    ?>
    <script type="text/javascript">
        jQuery('#email').closest('tr').removeClass('form-required').find('.description').remove();
        // Uncheck send new user email option by default
        <?php if (isset($form_type) && $form_type === 'add-new-user') : ?>
            jQuery('#send_user_notification').removeAttr('checked');
        <?php endif; ?>
    </script>
    <?php
}

remove_filter( 'authenticate', 'wp_authenticate_email_password', 20 );
