Problems while trying to upload image to server.

viperozza · May 2012

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<br /> $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

I had an issue with the boundary when trying to upload. I was uploading to a .net web service and not php. So, this may not work for you. My code stripped out a lot of what yours has and it is working. Here is how mine looked after I got it to work... My service expected a URL in the format:
http://www.domain.com/service1.svc/UploadPhotoOne/filename/jpg"
This is the format that I send as the url. The only thing I send in the body is the image data. I would save your original code and then test adding back in the other data elements within the body until you can get it to work.


-(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 *contentType = [NSString stringWithFormat:@"text/plain"];
[request addValue:contentType forHTTPHeaderField:@"Content-Type"];

NSMutableData *body = [NSMutableData data];

[body appendData:[NSData dataWithData:imageData]];
[request setHTTPBody:body];

[NSURLConnection sendSynchronousRequest:request returningResponse:nil error:nil];

// Do any additional setup after loading the view.

}

Howdy, Stranger!
