unable to get data from iphone application

Question

Hi, I have made a php web services that takes the username and password from iPhone application and saves the data in the users table.

I call that web service from my button touchup event like this:

 NSLog(userName.text);
 NSLog(password.text);

 NSString * dataTOB=[userName.text stringByAppendingString:password.text];

 NSLog(dataTOB);

 NSData * postData=[dataTOB dataUsingEncoding:NSUTF8StringEncoding allowLossyConversion:YES];

 NSString *postLength = [NSString stringWithFormat:@"%d", [postData length]];

 NSLog(postLength);

 NSMutableURLRequest *request = [[[NSMutableURLRequest alloc] init] autorelease];

 NSURL *url = [NSURL URLWithString:[NSString stringWithFormat:@"http://localhost:8888/write.php"]];

 [request setURL:url];
 [request setHTTPMethod:@"POST"];
 [request setValue:postLength forHTTPHeaderField:@"Content-Length"];
 [request setValue:@"application/x-www-form-urlencoded" forHTTPHeaderField:@"Content-Type"];
 [request setHTTPBody:postData];

 NSURLResponse *response;
 NSError *error;

 [NSURLConnection sendSynchronousRequest:request returningResponse:&response error:&error];

 if(error==nil)    
   NSLog(@"Error is nil");   
 else
   NSLog(@"Error is not nil");
 NSLog(@"success!");

I am getting nothing from Iphone side into the web service and I am unable to understand why this is happening. Although i debugged and found that everything is fine at the iphone application level but the call to the web service doesn't works as expected......

Please suggest.....

Thanks Ashish

Try logging localizedFailureReason or localizedRecoverySuggestion or localizedRecoveryOptions properties of 'error', if error is not nil. This may give you the reason if there is a failure encountered in sending the request or receiving the response.
