NSURL *url=[NSURL URLWithString:#"http://myserver.net/projects/mobile/test_login.php?name=abcd&password=123"];
NSData *postData = [post dataUsingEncoding:NSASCIIStringEncoding allowLossyConversion:YES];
NSString *postLength = [NSString stringWithFormat:#"%d", [postData length]];
NSMutableURLRequest *request = [[NSMutableURLRequest alloc] init];
[request setURL:url];
[request setHTTPMethod:#"POST"];
NSString *contentType = [NSString stringWithFormat:#"multipart/form-data"];
[request addValue:contentType forHTTPHeaderField: #"Content-Type"];
[request setValue:postLength forHTTPHeaderField:#"Content-Length"];
[request setValue:#"application/json" forHTTPHeaderField:#"Accept"];
[request setValue:#"application/x-www-form-urlencoded" forHTTPHeaderField:#"Content-Type"];
[request setHTTPBody:postData];
NSError *error = [[NSError alloc] init];
NSHTTPURLResponse *response = nil;
NSData *urlData=[NSURLConnection sendSynchronousRequest:request returningResponse:&response error:&error];
NSString *responseData = [[NSString alloc]initWithData:urlData encoding:NSUTF8StringEncoding];
NSLog(#"Response code: %d", [response statusCode]);
if ([responseData length]){
NSLog(#"Response ==> %#", responseData);
NSMutableDictionary *dict=[responseData JSONValue];
NSInteger success = [(NSNumber *) [dict objectForKey:#"success"] integerValue];
NSLog(#"%d",success);
if(success == 1){
//save the ID
NSInteger id1 = [(NSNumber *) [dict objectForKey:#"id"] integerValue];
NSUserDefaults *userData = [NSUserDefaults standardUserDefaults];
[userData setInteger:id1 forKey:#"id"];
[userData synchronize];
NSLog(#"id1 data is %#",userData);
NSLog(#"Login SUCCESS");
[self alertStatus:#"Logged in Successfully." :#"Login Success!"];
[self.navigationController pushViewController:overlay animated:YES];
} else {
NSString *error_msg = (NSString *) [dict objectForKey:#"error_message"];
[self alertStatus:error_msg :#"Login Failed!"];
}
