Multisite 'Welcome User Email' SITE_NAME returns 'network' name, not the name of the blog

The technique is basically the same as in the case of wpmu_signup_user_notification().

function wpmu_welcome_user_notification($user_id, $password, $meta = '') { global $current_site; $welcome_email = get_site_option( 'welcome_user_email' ); $user = new WP_User($user_id); $welcome_email = apply_filters( 'update_welcome_user_email', $welcome_email, $user_id, $password, $meta); // Get the current blog name $blogname = get_option( 'blogname' ); $welcome_email = str_replace( 'SITE_NAME', $blogname, $welcome_email ); $welcome_email = str_replace( 'USERNAME', $user->user_login, $welcome_email ); $welcome_email = str_replace( 'PASSWORD', $password, $welcome_email ); $welcome_email = str_replace( 'LOGINLINK', wp_login_url(), $welcome_email ); $admin_email = get_site_option( 'admin_email' ); if ( $admin_email == '' ) $admin_email = 'support@' . $_SERVER['SERVER_NAME']; $from_name = get_site_option( 'site_name' ) == '' ? 'WordPress' : esc_html( get_site_option( 'site_name' ) ); $message_headers = "From: \"{$from_name}\" <{$admin_email}>\n" . "Content-Type: text/plain; charset=\"" . get_option('blog_charset') . "\"\n"; $message = $welcome_email; $subject = apply_filters( 'update_welcome_user_subject', sprintf(__('New %1$s User: %2$s'), $blogname, $user->user_login) ); wp_mail($user->user_email, $subject, $message, $message_headers); return false; // make sure wpmu_welcome_user_notification() doesn't keep running } add_filter( 'wpmu_welcome_user_notification', 'bbg_wpmu_welcome_user_notification', 10, 3 );
