I'm trying to upload Image to the Server, Which I have done and works very well. But the problem I'm facing is I want to Upload Image as well as pass some parameter with that Image like Mobile Number..
I'm very new to android and also don't know anything about PHP side coding,,
I have tried the following code to upload Image, I added few more lines to pass Mobile Number with that Image. I really don't know is that right way or not but please correct me if I'm wrong...
public class MainActivity extends Activity implements OnClickListener{
private TextView messageText;
private Button uploadButton, btnselectpic;
private ImageView imageview;
private int serverResponseCode = 0;
private ProgressDialog dialog = null;
private String upLoadServerUri = null;
private String imagepath=null;
private String usernumber="3333333333";
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
uploadButton = (Button)findViewById(R.id.uploadButton);
messageText = (TextView)findViewById(R.id.messageText);
btnselectpic = (Button)findViewById(R.id.button_selectpic);
imageview = (ImageView)findViewById(R.id.imageView_pic);
btnselectpic.setOnClickListener(this);
uploadButton.setOnClickListener(this);
upLoadServerUri = "http://XXX.XX.X.XXX/Images/UploadToServer.php";
}
@Override
public void onClick(View arg0) {
if(arg0==btnselectpic)
{
Intent intent = new Intent();
intent.setType("image/*");
intent.setAction(Intent.ACTION_GET_CONTENT);
startActivityForResult(Intent.createChooser(intent, "Complete action using"), 1);
}
else if (arg0==uploadButton) {
dialog = ProgressDialog.show(MainActivity.this, "", "Uploading file...", true);
//messageText.setText("uploading started.....");
new Thread(new Runnable() {
public void run() {
UploadImageController.execute(,usernumber);
uploadFile(imagepath,usernumber);
}
}).start();
}
}
@Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
if (requestCode == 1 && resultCode == RESULT_OK) {
//Bitmap photo = (Bitmap) data.getData().getPath();
Uri selectedImageUri = data.getData();
imagepath = getPath(selectedImageUri);
Bitmap bitmap=BitmapFactory.decodeFile(imagepath);
imageview.setImageBitmap(bitmap);
// messageText.setText("Uploading file path:" +imagepath);
}
}
public String getPath(Uri uri) {
String[] projection = { MediaStore.Images.Media.DATA };
Cursor cursor = managedQuery(uri, projection, null, null, null);
int column_index = cursor.getColumnIndexOrThrow(MediaStore.Images.Media.DATA);
cursor.moveToFirst();
return cursor.getString(column_index);
}
public int uploadFile(String sourceFileUri) {
String fileName = sourceFileUri;
DataOutputStream dos = null;
String lineEnd = "\r\n";

// Responses from the server (code and message)

private static String convertStreamToString(InputStream is) {
BufferedReader reader = new BufferedReader(new InputStreamReader(is));
StringBuilder sb = new StringBuilder();
String line = null;
try {
while ((line = reader.readLine()) != null) {
sb.append(line + "\n");
}
} catch (IOException e) {
e.printStackTrace();
} finally {
try {

} catch (IOException e) {

return sb.toString();
}
}
}
This is the server side code to save the Image..
<?php
$file_path = "uploads/";
$file_path = $file_path . basename( $_FILES['uploaded_file']['name']);
if(move_uploaded_file($_FILES['uploaded_file']['tmp_name'], $file_path)) {
echo "success";
} else{
echo "fail";
}
?>
Please tell me how I can fetch that Mobile Number at server side???
I have done this recently with PHP CodeIgniter:
Android Side:
/*** POST THIS CODE AFTER
dos = new DataOutputStream(conn.getOutputStream());
***/
dos.writeBytes(twoHyphens + boundary + lineEnd);
dos.writeBytes("Content-Disposition: form-data; name=mobile_no" + lineEnd); // name=mobile_no so you have to get PHP side using mobile_no
dos.writeBytes(lineEnd);
dos.writeBytes(mobile_number); // mobile_no is String variable
dos.writeBytes(lineEnd);
PHP Side (Core PHP):
$mobile_no = $_POST['mobile_no'];
PHP Side (Using CodeIgniter Framework):
$mobile_no => $this->input->post('mobile_no');
Try this:
$mobileNumber = $_POST['userNumber']; // get mobile number from post
Since you are using POST method:
conn.setRequestMethod("POST");
And setting mobile number as:
conn.setRequestProperty("userNumber", usernumber);
