在更改密码时，我无法更改发送的电子邮件的主题。我已通过以下操作成功更改消息：
// Change Email to HTML function
function set_email_html_content_type() {
return \'text/html\';
}
// Replace the default password change email
add_filter(\'password_change_email\', \'change_password_mail_message\', 10, 3);
function change_password_mail_message( $change_mail, $user, $userdata ) {
// Call Change Email to HTML function
add_filter( \'wp_mail_content_type\', \'set_email_html_content_type\' );
$message = "<p>Test HTML email</p>";
$change_mail[ \'message\' ] = $message;
return $change_mail;
// Remove filter HTML content type
remove_filter( \'wp_mail_content_type\', \'set_email_html_content_type\' );
}
但是我如何更改默认为的主题
[Sitename] Notice of Password Change非常感谢。

这个$change_mail 正在筛选的变量具有subject 值，您可以使用与修改消息相同的方式修改该值：
// Replace the default password change email
add_filter(\'password_change_email\', \'change_password_mail_message\', 10, 3);
function change_password_mail_message( $change_mail, $user, $userdata ) {
// Call Change Email to HTML function
add_filter( \'wp_mail_content_type\', \'set_email_html_content_type\' );
$message = "<p>Test HTML email</p>";
$change_mail[ \'message\' ] = $message;
$change_mail[ \'subject\' ] = \'My new email subject\';
return $change_mail;
}
（我取消了您对的呼叫
remove_filter() 因为它什么都做不了。之后什么都没有
return 将运行。）

Try this:
/**
* Hooked into `password_change_email` filter hook.
*
* @param array $pass_change_email {
* Used to build wp_mail().
*
* @type string $to The intended recipients. Add emails in a comma separated string.
* @type string $subject The subject of the email.
* @type string $message The content of the email.
* The following strings have a special meaning and will get replaced dynamically:
* - ###USERNAME### The current user\'s username.
* - ###ADMIN_EMAIL### The admin email in case this was unexpected.
* - ###EMAIL### The user\'s email address.
* - ###SITENAME### The name of the site.
* - ###SITEURL### The URL to the site.
* @type string $headers Headers. Add headers in a newline (\\r\\n) separated string.
* }
*
* @param array $user The original user array.

function change_password_mail_message( $pass_change_email, $user, $userdata ) {
$subject = "Your new subject";
$message = "<p>Test HTML email</p>";
$headers[] = \'Content-Type: text/html\';
$pass_change_email[\'subject\'] = $subject;
$pass_change_email[\'message\'] = $message;
$pass_change_email[\'headers\'] = $headers;
return $pass_change_email;
}
/**
* Filters the contents of the email sent when the user\'s password is changed.
*
* @see change_password_mail_message()
*/
add_filter( \'password_change_email\', \'change_password_mail_message\', 10, 3 );
