How to upload data and string to sderver [Swift,Php]

In my swift app I've the following function:

func imageUploadRequest(imageView: UIImageView, uploadUrl: NSURL, param: [String:String]?) { let request = NSMutableURLRequest(url:uploadURL! as URL); request.httpMethod = "POST" let postParameters = "email=" + String(email) request.httpBody = postParameters.data(using: String.Encoding.utf8) let boundary = generateBoundaryString() request.setValue("multipart/form-data; boundary=\(boundary)", forHTTPHeaderField: "Content-Type") let imageData = UIImageJPEGRepresentation(imageView1.image!, 1.0) if (imageData == nil) { return } request.httpBody = createBodyWithParameters(parameters: param, filePathKey: "file", imageDataKey: imageData! as NSData, boundary: boundary) as Data let task = URLSession.shared.dataTask(with: request as URLRequest, completionHandler: { (data, response, error) -> Void in if let data = data { _ = try!JSONSerialization.jsonObject(with: data, options: .mutableContainers) as? NSDictionary } else if let error = error { print(error.localizedDescription) } }) task.resume() } 

func createBodyWithParameters(parameters: [String: String]?, filePathKey: String?, imageDataKey: NSData, boundary: String) -> NSData { let body = NSMutableData();

 if parameters != nil { for (key, value) in parameters! { body.appendString(string: "--\(boundary)\r\n") body.appendString(string: "Content-Disposition: form-data; name=\"\(key)\"\r\n\r\n") body.appendString(string: "\(value)\r\n") } } let filename = profilePicturePath let mimetype = "image/jpg" body.appendString(string: "--\(boundary)\r\n") body.appendString(string: "Content-Disposition: form-data; name=\"\(filePathKey!)\"; filename=\"\(filename)\"\r\n") body.appendString(string: "Content-Type: \(mimetype)\r\n\r\n") body.append(imageDataKey as Data) body.appendString(string: "\r\n") body.appendString(string: "--\(boundary)--\r\n") return body } func generateBoundaryString() -> String { return "Boundary-\(NSUUID().uuidString)" } func downloadImage(url: URL) { getDataFromUrl(url: url) { data, response, error in guard let data = data, error == nil else { return } print(response?.suggestedFilename ?? url.lastPathComponent) DispatchQueue.main.async() { self.imageView1.image = UIImage(data: data) self.tableView.reloadData() } } } 

USER_IMG_SET.php

$email = $_POST['email']; //$email = "[email protected]"; $target_dir = "../usersAccountData/".$email; if(!file_exists($target_dir)) { mkdir($target_dir, 0755, true); } $target_dir = $target_dir . "/" . basename($_FILES["file"]["name"]); if (move_uploaded_file($_FILES["file"]["tmp_name"], $target_dir)) { echo json_encode([ "Message" => "The file ". basename( $_FILES["file"]["name"]). " has been uploaded.", "Status" => "OK", "userId" => $_REQUEST["userId"] ]); } else { echo json_encode([ "Message" => "Sorry, there was an error uploading your file.", "Status" => "Error", "userId" => $_REQUEST["userId"] ]); } 

I uploaded image data and I also want to upload the user email in php ($email = $_POST['email'];) with the same request. How can I do it?
