Java android如何使用php制作上传图片并将标题插入mysql

我不能在我的项目上插入标题，我希望我的项目可以上载图像并将一些数据插入web服务器上的数据库，我可以插入，但我的数据有一个副本。。请帮帮我

这里是MainActivity.java的源代码

public class MainActivity extends Activity implements OnClickListener{

private TextView messageText;
private EditText Txnama, Txtanggal, Txcaption;
private Button uploadButton, btnselectpic;
private ImageView imageview;
private int serverResponseCode = 0;
private ProgressDialog dialog = null;

private String upLoadServerUri = null;
private String imagepath=null;
@Override
public void onCreate(Bundle savedInstanceState) {

    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);

    uploadButton = (Button)findViewById(R.id.uploadButton);
    btnselectpic = (Button)findViewById(R.id.button_selectpic);
    messageText  = (TextView)findViewById(R.id.messageText);
    imageview = (ImageView)findViewById(R.id.imageView_pic);
    Txnama = (EditText)findViewById(R.id.nama);
    Txtanggal = (EditText)findViewById(R.id.tanggal);
    Txcaption = (EditText)findViewById(R.id.caption);


    btnselectpic.setOnClickListener(this);
    uploadButton.setOnClickListener(this);
    upLoadServerUri = "http://aplikasilaras.esy.es/php/Uploadcoba.php";
    ImageView img= new ImageView(this);        
}

试着用这个来改变php代码，这对我来说很有用

<?php

$conn = mysql_connect('YOUR_HOST', 'YOUR_USERNAME', 'YOUR_PASSWORD') or die(mysql_error());
$db = mysql_select_db('YOUR_DB_NAME') or die(mysql_error());

$file_path = "uploads/"; //YOUR FOLDER FOR SAVING IMAGE, MY FOLDER NAME IS uploads

$file_path = $file_path . basename( $_FILES['uploaded_file']['name']);
if(move_uploaded_file($_FILES['uploaded_file']['tmp_name'], $file_path)) {
    $query = "insert into YOUR_TABLE_NAME values('', '$file_path')"; 
    mysql_query($query);
    echo "success";
} else{
    echo "fail";
}
?>
