In this example uploading an image from sdcard to web server.
Steps :
1. place an image on sdcard.
2. place sdcard image path and image name in UploadToServer.java. ( see below )
3. create a php script (UploadToServer.php) at server. ( see below )
4. place php script path in UploadToServer.java. ( see below )
5. create folder name uploads on server where you have placed php script.
6. give permission 777 (read/write/execute) to uploads folder.

Php script at server :
File : UploadToServer.php
<?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"; } ?> |
