Error sending http post request with image - iphone

Question

I'm stucked in this problem since days and i really need your help.
I'm actually trying to upload a file from my iphone app to a webserver trough a php script.
this is my method in Xcode:
-(void)sendPost{
UIImageView *imageView = [[UIImageView alloc] init];
imageView.image = [UIImage imageNamed:#"back.png"];
NSData *imageData = UIImageJPEGRepresentation(imageView.image, 90);
NSString *urlString = #"myscriptishere.php";
NSMutableURLRequest *request = [[NSMutableURLRequest alloc]init];
[request setTimeoutInterval:60.0];
[request setURL:[NSURL URLWithString:urlString]];
[request setHTTPMethod:#"POST"];
NSString *boundary = [NSString stringWithString:#"---------------------------14737809831466499882746641449"];
NSString *contentType = [NSString stringWithFormat:#"multipart/form-data; boundary=%#",boundary];
[request addValue:contentType forHTTPHeaderField:#"Content-Type"];
NSMutableData *body = [NSMutableData data];
[body appendData:[[NSString stringWithFormat:#"\r\n--%#\r\n",boundary] dataUsingEncoding:NSUTF8StringEncoding]];
[body appendData:[[NSString stringWithString:#"Content-Disposition: form-data; name=\"userfile\";filename=\"myfile.png\"\r\n"]
dataUsingEncoding:NSUTF8StringEncoding]];
[body appendData:[[NSString stringWithString:#"Content-Type: application/octet-stream\r\n\r\n"] dataUsingEncoding:NSUTF8StringEncoding]];
[body appendData:[NSData dataWithData:imageData]];
[body appendData:[[NSString stringWithFormat:#"\r\n--%#\r\n",boundary] dataUsingEncoding:NSUTF8StringEncoding]];
[request setHTTPBody:body];
NSLog(#"%#",[[NSString alloc] initWithData:[NSURLConnection sendSynchronousRequest:request returningResponse:nil error:nil] encoding:NSUTF8StringEncoding]);
// Do any additional setup after loading the view.
}
and my php code is:
<?php
$domainpath = $_SERVER['DOCUMENT_ROOT'];
$target = "./upload";
$public = "/public/upload/";
$target = $target.basename( $_FILES['userfile']['name']) ;
$check = getimagesize($_FILES['userfile']['tmp_name']);
if (move_uploaded_file($_FILES["file"]["tmp_name"],
$domainpath. $public . $_FILES["file"]["name"]))
echo "YES";
else
echo "NO";
?>
I always receive (after few seconds, so I guess I'm uploading something) the server reply "NO".
I already checked I have permission on the folder I'm going to write in.
Any ideas on where the problem could be hidin?
Thanx in advance

Your problem is here:
NSString *urlString = #"myscriptishere.php";
NSMutableURLRequest *request = [[NSMutableURLRequest alloc]init];
[request setTimeoutInterval:60.0];
[request setURL:[NSURL URLWithString:urlString]];
You are posting to a filename. Your urlString variable should hold full address including protocol and domain (like #"http://localhost/myscriptishere.php").
