私が行っていることは次のとおりです。ユーザーがiPhoneアプリを使用して写真と写真の2つの説明フィールドをMySQLにアップロードできるようにします。2つの説明フィールドからのテキストがアップロードされるようにアプリを構成する方法をすでに理解しました（PostURLとそれに付随するWebサーバー上の.phpファイルを使用）。
私が問題に直面しているのは、写真をミックスに追加し、写真とテキストのフィールドをデータベースの対応する列（画像、名前、メッセージ）に一緒に送信する方法です。
ヘッダーファイルと実装ファイルはどのようになりますか？そして、追加のボーナスとして、私の.phpファイルはどのように見えるべきですか？現在の状況は次のとおりです。参考までに、これは写真ではなくテキストの送信にのみ機能します。
ヘッダーファイル：
#import <UIKit/UIKit.h>
#define kPostURL @"http://www.example.com/upload.php"
#define kName @"name"
#define kMessage @"message"
@interface FirstViewController : UIViewController<UINavigationControllerDelegate, UIImagePickerControllerDelegate>{
IBOutlet UITextField *nameText;
IBOutlet UITextView *messageText;
NSURLConnection *postConnection;
UIImageView * theimageView;
UIButton * choosePhoto;
