title: Upload image , video and audio file to a php web service in iphone
body: <p>I am facing issues in uploading media files to a web service built in php.
  I have an app along with source code in android and I am suppose to replicate it in iphone.
  There is this part where I am supposed to upload media files along with some strings to a web service.
           The code in android uses a class called MultiPartEntity and HTTPPost to upload it.
  There are several tags , and the tags are associated with some strings.</p>
  
  <p>for ex.MultiPartEntity mpEntity.addPart("username", "abc");, similarly for password and other tags.</p>
  
  <p>I made some research and I found ASIFormDataRequest which deals with similar things.</p>
  
  <p>here is the sample code I am using to upload media along with some other detials,</p>
  
  <p>NSData *imageData = UIImageJPEGRepresentation(image.image, 90);
      NSMutableURLRequest *request = [[[NSMutableURLRequest alloc] init] autorelease];
      [request setURL:[NSURL URLWithString:@"http://my.url.com/somephpwebservice.php"]];
      [request setHTTPMethod:@"POST"];</p>
  
  <pre><code>NSString *boundary = [NSString stringWithString:@"---------------------------14737809831466499882746641449"];
  NSString *contentType = [NSString stringWithFormat:@"multipart/form-data; boundary=%@",boundary];
  [request addValue:contentType forHTTPHeaderField: @"Content-Type"];
  
  // now lets create the body of the post 
  NSMutableData *body = [NSMutableData data];
  
  //................................ Append the image data here//u= \"TP\";p= \"7012\";o= \"DEMO\";j= \"1151\"...........................
  //if (!([htmlCodeToWrite rangeOfString:@"SignatureShouldBeDoneHere"].location == NSNotFound))
  //{
      [body appendData:[[NSString stringWithFormat:@"\r\n--%@\r\n",boundary] dataUsingEncoding:NSUTF8StringEncoding]];    
      [body appendData:[[NSString stringWithFormat:@"Content-Disposition: form-data;name=\"userfile\";username=\"TP\";p=\"7012\";filename=\"%@\"\r\n",@"superman.jpg"] dataUsingEncoding:NSUTF8StringEncoding]];
      //[body appendData:[[NSString stringWithString:@"Content-Type: application/octet-stream\r\n\r\n"] dataUsingEncoding:NSUTF8StringEncoding]];
      [body appendData:[@"Content-Type: image/jpeg\r\n\r\n" dataUsingEncoding:NSUTF8StringEncoding]];
      [body appendData:[NSData dataWithData:imageData]];
  //}
  //NSString *content = [NSString stringWithUTF8String:[imageData bytes]];
  NSLog(@"%@",imageData);
  [body appendData:[[NSString stringWithFormat:@"\r\n--%@--\r\n",boundary] dataUsingEncoding:NSUTF8StringEncoding]];
  
  //data into the string..... verifying............
  NSString *strTest = [[NSString alloc] initWithData:body encoding:NSASCIIStringEncoding];
  NSLog(@"%@ %@",@".....the request for webService",strTest);
  
  // setting the body of the post to the request
  [request setHTTPBody:body];
  
  // now lets make the connection to the web
  NSData *returnData = [NSURLConnection sendSynchronousRequest:request returningResponse:nil error:nil];
  
  NSString *returnString = [[NSString alloc] initWithData:returnData encoding:NSUTF8StringEncoding];
  
  NSLog(@"%@ %@",returnString,@".....the response from webService");
  </code></pre>
  
  <p>Is this the proper procedure.??</p>
  
  <p>The php developer says the image is not getting uploaded.</p>
  
  <p>Please help.
  Thanx in advance.</p>
