Upload file from device to server using PhoneGap

I have implemented this in Android and it works really well. You may need to customize client side implementation little as per you requirement and it should work fine.
Since we dont have file structure in iPhone, I am not sure how to implement it in iPhone.

 1. Client(device) side implementation
PhoneGap provides file transfer API to transfer file to server, PHP is recommended for server implementation.

function uploadFile() {
   window.requestFileSystem(LocalFileSystem.PERSISTENT, 0, function(fs) {
   var directoryReader = fs.root.createReader();
   directoryReader.readEntries(function(entries) {
   imageURI=entries[0].toURI(); // Selected File path
   var options = new FileUploadOptions();
   options.chunkedMode = false;
   options.fileKey="file";
   options.fileName=imageURI.substr(imageURI.lastIndexOf('/')+1);
   alert(options.fileName);
   options.mimeType="text/plain";
   var params = new Object();
   params.value1 = "test";
   params.value2 = "param";
   options.params = params;
   var ft = new FileTransfer();
   ft.upload(imageURI, "ServerIP/Upload.php", win, fail, options,true);
   }, function (error) {
      alert(error.code);
   })}, function (error) {
      alert(error.code);
   });
}

function win(r) {
   alert("success");
   alert("Sent = " + r.bytesSent);
}

function fail(error) {
   alert("error");
   switch (error.code) {
     case FileTransferError.FILE_NOT_FOUND_ERR:
        alert("Photo file not found");
        break;
     case FileTransferError.INVALID_URL_ERR:
       alert("Bad Photo URL");
       break;
     case FileTransferError.CONNECTION_ERR:
       alert("Connection error");
       break;
   }
   alert("An error has occurred: Code = " + error.code);
}

2. Server side implementation
Create a php page(Upload.php) and host it in IIS

<?php
if ($_FILES["file"]["error"] > 0) {
  echo "Return Code: " . $_FILES["file"]["error"] . "";
} else {
  echo "Upload: " . $_FILES["file"]["name"] . "";
  echo "Type: " . $_FILES["file"]["type"] . "";
  echo "Size: " . ($_FILES["file"]["size"] / 1024) . " Kb";
  echo "Temp file: " . $_FILES["file"]["tmp_name"] . "";
  if (file_exists("D:/PHPUPLOAD/" . $_FILES["file"]["name"])) {
    echo $_FILES["file"]["name"] . " already exists. ";
  } else {
    move_uploaded_file($_FILES["file"]["tmp_name"], "C:/PHPUPLOAD/" . $_FILES["file"]["name"]); //Save location
    echo "Stored in: " . "upload/" . $_FILES["file"]["name"];
  }
}
?>
For example: Create a php file(Upload.php) at – C:\inetpub\wwwroot
