Failed to get data from iphone application

Question

I made php web services that take username and password from iPhone application and save data in user table.

I call this web service from the touchup event for this button as follows:

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 don’t get anything from Iphone in the web service and I can’t understand why this is happening. Although I debugged and found that at the iphone level everything is fine, but the web service call does not work as expected ......

Please suggest .....

Thanks Ashish

Try registering localizedFailureReason or localizedRecoverySuggestion or localizedRecoveryOptions of the "error" property if the error is not zero. This may indicate the cause of the failure when sending a request or receiving a response.
