title: Trouble Passing Variables to PHP Script on Image Upload
body: <p>I have a script that successfully uploads an image to my server via PHP. THe upload part works, but I am also trying to pass variables to the PHP script that is uploading the image.</p>
  
  <p>I am pretty confident that my PHP code is just fine, I just dont know whats going wrong with the Objective-C. I also notice that I never call NSData *... = [NSData dataWithContentsOfURL:[NSURL URLWithString:...]]; But I dont know if thats the problem...</p>
  
  <pre><code>NSData *data = UIImageJPEGRepresentation(twitterImage, 90);
  
  NSString *profileId = [[NSUserDefaults standardUserDefaults] stringForKey:@"passedId"];
  NSString *userId = [[NSUserDefaults standardUserDefaults] stringForKey:@"userId"];
  NSString *urlString = [NSString 
  stringWithFormat:@"http://www.website.com/user_photo_upload.php?
  member_id=%@&amp;profile_id=%@",userId, profileId];
  
      NSMutableURLRequest *request = [[NSMutableURLRequest alloc] init];
      [request setURL:[NSURL URLWithString:urlString]];
      [request setHTTPMethod:@"POST"];
  
      NSString *boundary = @"_783465873689273842734";
      NSString *contentType = [NSString stringWithFormat:@"multipart/form-data; 
      boundary=%@",boundary];
      [request setValue:contentType forHTTPHeaderField: @"Content-Type"];
      [request setValue:@"text/html,application/xhtml+xml,application/xml;q=0.9,*/*;q=0.8" 
      forHTTPHeaderField:@"Accept"];
      [request setValue:@"Mozilla/5.0 (Macintosh; Intel Mac OS X 10_7_5)

      forHTTPHeaderField:@"User-Agent"];
      [request setValue:@"http://google.com" forHTTPHeaderField:@"Origin"];
  
      NSMutableData *body = [NSMutableData data];
      [body appendData:[[NSString stringWithFormat:@"Content-Length %d\r\n\r\n", [data 
      length] ] dataUsingEncoding:NSUTF8StringEncoding]];
      [body appendData:[[NSString stringWithFormat:@"\r\n--%@\r\n",boundary] 
      dataUsingEncoding:NSUTF8StringEncoding]];
      [body appendData:[[NSString stringWithFormat:@"Content-Disposition: form-data; 
      name=\"picture\"; filename=\"%@.png\"\r\n", @"newfile"] 
      dataUsingEncoding:NSUTF8StringEncoding]];
  
      [body appendData:[@"Content-Type: application/octet-stream\r\n\r\n" 
      dataUsingEncoding:NSUTF8StringEncoding]];
  
      [body appendData:[NSData dataWithData:data]];
  
      [body appendData:[[NSString stringWithFormat:@"\r\n--%@--\r\n",boundary] 
      dataUsingEncoding:NSUTF8StringEncoding]];
  
      [request setHTTPBody:body];
      [request addValue:[NSString stringWithFormat:@"%d", [body length]] 
      forHTTPHeaderField:@"Content-Length"];
  
      NSData *returnData = [NSURLConnection sendSynchronousRequest:request 
      returningResponse:nil error:nil];
      NSString *returnString = [[NSString alloc] initWithData:returnData 
      encoding:NSUTF8StringEncoding];
      NSLog(@"%@", returnString);
