我正在尝试更改新网站通知（wpmu\\u welcome\\u通知）的文本：
在核心文件中，我看到wordpress在创建新网站时使用此功能发送电子邮件：
问题是，我如何挂接此函数以更改“$welcome\\u email”中使用的正文文本
function wpmu_welcome_notification( $blog_id, $user_id, $password, $title, $meta = array() ) {
$current_site = get_current_site();
/**
* Filter whether to bypass the welcome email after site activation.
*
* Returning false disables the welcome email.
*
* @since MU
*
* @param int|bool $blog_id Blog ID.
* @param int $user_id User ID.
* @param string $password User password.
* @param string $title Site title.
* @param array $meta Signup meta data.

if ( ! apply_filters( \'wpmu_welcome_notification\', $blog_id, $user_id, $password, $title, $meta ) )
return false;
$welcome_email = get_site_option( \'welcome_email\' );

$welcome_email = __( \'Howdy USERNAME,

下面是一个未经测试的示例，您如何根据需要修改电子邮件正文：
add_filter( \'update_welcome_email\',
function( $welcome_email, $blog_id, $user_id, $password, $title, $meta )
{
// Override the email body:
$welcome_email = __( \'Dear User,
Your new SITE_NAME site has been successfully set up at:
BLOG_URL
You can log in to the administrator account with the following information:
Username: USERNAME
Password: PASSWORD
Log in here: BLOG_URLwp-login.php
We hope you enjoy your new site. Thanks!
--The Team @ SITE_NAME\' );
$current_site = get_current_site();
$url = get_blogaddress_by_id($blog_id);
$user = get_userdata( $user_id );
return str_replace(
array( \'SITE_NAME\', \'BLOG_TITLE\', \'BLOG_URL\', \'USERNAME\', \'PASSWORD\' ),
array( $current_site->site_name, $title, $url, $user->user_login, $password ),
$welcome_email
);
}
, 10, 6 );
