we have a gravityform which has a multiple upload field and want when user upload files the files upload to a second host via ftp connection how can we implement this? here what we do until now the main site is mysite.com and the subdomain which hosted on another hsoting is files.mysite.com add_filter( 'gform_upload_path', 'change_upload_path', 10, 2 ); function change_upload_path( $path_info, $form_id ) { // FTP credentials for host two $ftp_host = '***'; $ftp_username = '***'; $ftp_password = '***'; // Remote path on host two where files should be uploaded $remote_path = '/public_html/guaranty_uploads/'; // Connect to host two via FTP $ftp_connection = ftp_connect($ftp_host); ftp_login($ftp_connection, $ftp_username, $ftp_password); // Set the FTP upload directory on host two ftp_chdir($ftp_connection, $remote_path); // Update the path_info array with the FTP details $path_info['path'] = $remote_path; $path_info['url'] = 'http://files.mysite.com/guaranty_uploads/'; $path_info['ftp_connection'] = $ftp_connection; return $path_info; } best regards
