Data uploaden

[Tim14ww]

Hoi,

Ik probeer data te uploaden in m'n database, met de volgende code:

-(IBAction)update{
		NSString *post = @"key1=val1&key2=val2";
		NSData *postData = [post dataUsingEncoding:NSASCIIStringEncoding allowLossyConversion:YES];
		
		NSString *postLength = [NSString stringWithFormat:@"%d", [postData length]];
		
		NSMutableURLRequest *request = [[[NSMutableURLRequest alloc] init] autorelease];
		[request setURL:[NSURL URLWithString:[NSString stringWithFormat:@"http://www.marvinvdgraaff.nl/onsys/test.php?naam=%@",[userName text]]]];
		[request setHTTPMethod:@"POST"];
		[request setValue:postLength forHTTPHeaderField:@"Content-Length"];
		[request setValue:@"application/x-www-form-urlencoded" forHTTPHeaderField:@"Content-Type"];
		[request setHTTPBody:postData];
		
		NSURLConnection *conn=[[NSURLConnection alloc] initWithRequest:request delegate:self];
		if (conn) 
		{
			NSLog(@"Gelukt!");
		} 
		else 
		{
			// inform the user that the download could not be made
			NSLog(@"Mislukt!!");
		}
		
	}

[userName text] is dus het textfield dat ik verzonden wil hebben, maar nu krijg ik dus in m'n database een leeg veld aan, dus wat doe ik fout?

moet ik niets veranderen aan: NSString *post = @"key1=val1&key2=val2"; ??

Alvast bedankt,

Tim!
