How to use wpmu_signup_blog_notification function to send a notification for a new blog signup
The wpmu_signup_blog_notification function is used to send a notification email to a user who has signed up for a new blog. Here is an example of how to use it:
$domain = 'mynewblog.com';
$path = '/mynewblog/';
$title = 'My New Blog';
$user_login = 'newuser';
$user_email = '[email protected]';
$key = 'activationkey123';
$meta = array('lang_id' => 1);
wpmu_signup_blog_notification($domain, $path, $title, $user_login, $user_email, $key, $meta);
In this example, we are sending a notification to the email address [email protected] about the creation of a new blog with the domain mynewblog.com. The activation key for this blog is activationkey123. The meta data contains information about the blog’s language id.
How to check if wpmu_signup_blog_notification function is successful
We can check if the wpmu_signup_blog_notification function is successful by checking its return value. If it returns true, the function is successful. If it returns false, the function has failed.
$domain = 'mynewblog.com';
$path = '/mynewblog/';
$title = 'My New Blog';
$user_login = 'newuser';
$user_email = '[email protected]';
$key = 'activationkey123';
$meta = array('lang_id' => 1);
if (wpmu_signup_blog_notification($domain, $path, $title, $user_login, $user_email, $key, $meta)) {
echo "<p>Notification sent successfully</p>";
} else {
echo "<p>Failed to send notification</p>";
}
In this example, we send the notification as before. But this time, we check the return value of the function. If it’s true, we print a success message. If it’s false, we print a failure message.
How to use wpmu_signup_blog_notification function without metadata
The $meta parameter is optional in the wpmu_signup_blog_notification function. If we don’t provide it, the function will use its default value. Here is an example of how to use the function without the $meta parameter:
$domain = 'mynewblog.com';
$path = '/mynewblog/';
$title = 'My New Blog';
$user_login = 'newuser';
$user_email = '[email protected]';
$key = 'activationkey123';
wpmu_signup_blog_notification($domain, $path, $title, $user_login, $user_email, $key);
In this example, we don’t provide the $meta parameter when calling the function. So, the function will use its default value for the $meta parameter.
