Question

i am trying to create a login page for iPad by using Mysql through PHP, But it is not logging in even though there is no error in page, please find the code below:

//-(IBAction)homePage: (id)sender{

NSString *post =[NSString stringWithFormat:@"username=%@&password=%@",loginName.text, password.text];

NSString *hostStr = @"http://localhost/iddb.php";
hostStr = [hostStr stringByAppendingString:post];
NSData *dataURL =  [NSData dataWithContentsOfURL: [ NSURL URLWithString: hostStr ]];    
NSString *serverOutput = [[NSString alloc] initWithData:dataURL encoding: NSASCIIStringEncoding];
if([serverOutput isEqualToString:@"Yes"]){{ 


    homepage *hvc = [[homepage alloc]initWithNibName: nil bundle: nil];
    hvc.modalTransitionStyle=UIModalTransitionStyleFlipHorizontal;
    [self presentModalViewController:hvc animated: YES];}

    UIAlertView *alertsuccess = [[UIAlertView alloc] initWithTitle:@"success" message:@"You are authorized"
                                                          delegate:self cancelButtonTitle:@"No" otherButtonTitles:@"Yes", nil];
    [alertsuccess show];


} else {
    UIAlertView *alertsuccess = [[UIAlertView alloc] initWithTitle:@"Fail" message:@"Invalid Access"
                                                          delegate:self cancelButtonTitle:@"No" otherButtonTitles:@"Yes", nil];
    [alertsuccess show];


}

PHP Code:

<?php
    $username = $_GET['username'];
    $password = $_GET['password'];
    $check = "select username, password from login where username='$username' and password='$password'";
    {
      mysql_connect("localhost", "root","") or die();
      mysql_select_db("dadsdb") or die (mysql_error());
    }

    $login = mysql_query($check) or die (mysql_error());

    if (mysql_num_rows($login)==1) {
      $row = mysql_fetch_assoc($login);
      echo 'yes';
      exit;
    } else {
      echo 'No';
      exit;
    }
?>
