AFNetworking Uploading Image

I've look at a few examples but I think my problem may be with in the PHP. I am trying to upload an image to a server from the iphone using AFNetworking. Here is my obj-c code: ``` -(IBAction)uploadButtonClicked:(id)sender { NSData *imageToUpload = UIImageJPEGRepresentation(mainImageView.image, 90); AFHTTPClient *client= [AFHTTPClient clientWithBaseURL:[NSURL URLWithString:@"http://www.THESERVER.com"]]; NSMutableURLRequest *request = [client multipartFormRequestWithMethod:@"POST" path:@"/PROJECT/upload.php" parameters:nil constructingBodyWithBlock: ^(id <AFMultipartFormData>formData) { [formData appendPartWithFileData: imageToUpload name:@"file" fileName:@"temp.jpeg" mimeType:@"image/jpeg"]; }]; AFHTTPRequestOperation *operation = [[AFHTTPRequestOperation alloc] initWithRequest:request]; [operation setCompletionBlockWithSuccess:^(AFHTTPRequestOperation *operation, id responseObject) { NSString *response = [operation responseString]; NSLog(@"response: [%@]",response); [MBProgressHUD hideHUDForView:self.view animated:YES]; } failure:^(AFHTTPRequestOperation *operation, NSError *error) { [MBProgressHUD hideHUDForView:self.view animated:YES]; if([operation.response statusCode] == 403){ NSLog(@"Upload Failed"); return; } NSLog(@"error: %@", [operation error]); }]; [operation start]; } ``` This is my upload.php: ``` function upload(){ $uploaddir = '/uploads/'; $file = basename($_FILES['file']['name']); $uploadfile = $uploaddir . $file; if (move_uploaded_file($_FILES['file']['tmp_name'], $uploadfile)) { sendResponse(200, 'Upload Successful'); return true; } sendResponse(403, 'Upload Failed'); return false; } ``` When I try to upload it fails at ``` if (move_uploaded_file($_FILES['file']['tmp_name'], $uploadfile)) { ``` and returns the 403 / false status code that I set
