I have been putting up with the emails automatically sent by this website for a long time. I can’t bear to look directly at the machine-translated Chinese and ugly text layout interface. Take advantage of the free time this weekend to manually adjust it. Show off the finished product first, it feels pretty good:

Share the email template html source code:

Setting up unattended self-response emails can be achieved through third-party WordPress plug-ins, such as WP Mail SMTP, etc. It is very simple to get started. After installing the plug-in, just adjust each email module page by referring to the above email HTML template. Of course, you can also implement it in pure code without using plug-ins. Just use hooks to replace the WordPress native email content and style.

Due to limited space, the following is an excerpt of the password retrieval email content and format replacement implemented by me using the hook function. The content and format settings of email verification codes, new user registration notifications, and account deactivation emails have similar principles and are omitted here.

//Password retrieval email text customization
function dmd_filter_retrieve_password_notification_email( $defaults, $key, $user_login, $user_data ){

// Use the three parameters $key, $user_login, $user_data to obtain and transfer user information to achieve dynamic email content
//Automatically obtain the current time as the email sending time and manually set the time zone to PRC China
date_default_timezone_set('PRC');
$sendtime = date("Y-m-d H:i:s");
$defaults['headers'] = "MIME-Version: 1.0\n" . "Content-Type: text/html;"; //Normally no modification is required
//$defaults['title'] = "Password Retrieval - IT Lullaby"; //Doesn't work... The following is implemented through a custom email title hook function
$defaults['message'] = '
<meta charset="UTF-8">
