Examples

// Redefine user notification function
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);

	$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(__('E-mail: %s'), $user->user_email) . "\r\n";

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

	if ( 'admin' === $notify || 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 ) );

	$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\r\n";
        $message .= sprintf( __('If you have any problems, please contact us at %s.'), get_option('admin_email') ) . "\r\n\r\n";
	$message .= __('Adios!') . "\r\n\r\n";

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

Notes

• This function can be replaced via plugins. If plugins do not redefine these functions, then this will be used instead.
• As of WP 4.3, a plain text password is no longer passed to the function. If you have a plugged version of this function and are assuming that the second function argument is `$plaintext_pass`, the password displayed in your email to the user will be "admin" or "both".
• As of WP 4.3.1, null value is passed as second function argument. So if you have a plugged version of this function and are assuming that the second function argument is `$plaintext_pass` then the newly registered user will not receive their welcome email.

Change Log

• Since: 2.0
• Since: 4.3 The $plaintext_pass parameter was changed to $notify
• Since: 4.3.1 The $plaintext_pass parameter was deprecated. $notify added as a third parameter.
