How to Disable New User Notifications in WordPress

我的 WordPress 網站有安裝「Social Login WordPress Plugin – AccessPress Social Login Lite」外掛,也造成每天都有大約 1~3人的新會員註冊。已經在AccessPress Social Login Lite 裡設定不要收到通知信:「Do not send email notification to both user and site admin.」,但還是一直收到通知信,然後在WordPress 的設定裡找不到可以關掉通知的地方,所以每天都會收到超多的這種垃圾信:《摩卡平價小舖》通知:新使用者註冊

由於是寄到 Gmail,手機三不五時會彈通知出來,實在很煩。試著安裝外掛:
Better Notifications for WordPress
https://tw.wordpress.org/plugins/bnfw/

但找不到可以設定的地方。

改安裝外掛:
Disable New User Notification Emails
https://wordpress.org/plugins/disable-new-user-notifications/

這個外掛,完全沒有地方可以設定,因為:This plugin disables new user notification emails in WordPress. That is all.

經測試在 wordpress 5.2,還是會收到信 Q_Q;

再挑戰看看使用:Tweakr – Utility Toolkit

只好直接在Gmail 裡設定「篩選條件」,直接在伺服器刪除。


其他解法:透過修改外觀主題的 functions.php:
https://wordpress.stackexchange.com/questions/236122/turn-off-new-user-registration-emails

add_action( 'init', function() {
     remove_action( 'register_new_user', 'wp_send_new_user_notifications' );
     add_action( 'register_new_user', 'wpse236122_send_new_user_notifications' );
 } );

function wpse236122_send_new_user_notifications( $user_id, $notify = 'user' ) {
     wp_send_new_user_notifications( $user_id, $notify );
 }

修改 functions.php 的解法 2:
Turn off admin emails for new user registrations
https://wordpress.stackexchange.com/questions/90311/turn-off-admin-emails-for-new-user-registrations

The function that you’re looking for is wp_new_user_notification it’s a pluggable function. Pluggable functions are function that let you override WordPress Core functionalities.

You can override, simply by:

  1. Create a file in mu-plugins folder, you can call whatever you want, but you should give a meaningful name, like custom-new-user-notification.php
  2. Copy the default function and wrapping it in a if statement checking if the function doesn’t exist. (it’s a best practice if not it can produce errors)
  3. Change the message and subject ( or whatever you want to change)

Example:

   <?php
        /*
        Plugin Name:     Custom User Notification
        Plugin URI:      http://www.example.com
        Description:     Pligin description
        Version:         1.0
        Author:          Your Name
        Author URI:      http://www.authorurl.com
        */


        if( !function_exists( 'wp_new_user_notification' ) ){

            function wp_new_user_notification( $user_id, $deprecated = null, $notify = '' ) {
                if ( $deprecated !== null ) {
                    _deprecated_argument( __FUNCTION__, '4.3.1' );
                }

                global $wpdb, $wp_hasher;
                $user = get_userdata( $user_id );

                // The blogname option is escaped with esc_html on the way into the database in sanitize_option
                // we want to reverse this for the plain text arena of emails.
                $blogname = wp_specialchars_decode(get_option('blogname'), ENT_QUOTES);

                if ( 'user' !== $notify ) {
                    $switched_locale = switch_to_locale( get_locale() );
                    $message  = sprintf( __( 'New user registration on your site %s:' ), $blogname ) . "\r\n\r\n";
                    $message .= sprintf( __( 'Username: %s' ), $user->user_login ) . "\r\n\r\n";
                    $message .= sprintf( __( 'Email: %s' ), $user->user_email ) . "\r\n";

                    @wp_mail( get_option( 'admin_email' ), sprintf( __( '[%s] New User Registration' ), $blogname ), $message );

                    if ( $switched_locale ) {
                        restore_previous_locale();
                    }
                }

                // `$deprecated was pre-4.3 `$plaintext_pass`. An empty `$plaintext_pass` didn't sent a user notification.
                if ( 'admin' === $notify || ( empty( $deprecated ) && empty( $notify ) ) ) {
                    return;
                }

                // Generate something random for a password reset key.
                $key = wp_generate_password( 20, false );

                /** This action is documented in wp-login.php */
                do_action( 'retrieve_password_key', $user->user_login, $key );

                // Now insert the key, hashed, into the DB.
                if ( empty( $wp_hasher ) ) {
                    require_once ABSPATH . WPINC . '/class-phpass.php';
                    $wp_hasher = new PasswordHash( 8, true );
                }
                $hashed = time() . ':' . $wp_hasher->HashPassword( $key );
                $wpdb->update( $wpdb->users, array( 'user_activation_key' => $hashed ), array( 'user_login' => $user->user_login ) );

                $switched_locale = switch_to_locale( get_user_locale( $user ) );

                $message = sprintf(__('Username: %s'), $user->user_login) . "\r\n\r\n";
                $message .= __('To set your password, visit the following address:') . "\r\n\r\n";
                $message .= '<' . network_site_url("wp-login.php?action=rp&key=$key&login=" . rawurlencode($user->user_login), 'login') . ">\r\n\r\n";

                $message .= wp_login_url() . "\r\n";

                wp_mail($user->user_email, sprintf(__('[%s] Your username and password info'), $blogname), $message);

                if ( $switched_locale ) {
                    restore_previous_locale();
                }
            }

        }

再進階一點的問題,就是「如何客製化歡迎使用者加入的確認信」,客製化Welcome email 的 plugin 還滿多的。
