title: $.ajax Post Request not sending POST data
body: <p>I'm trying to streamline my login system by using ajax to handle to back and form requests to the server. I want to POST my form data to a PHP page, then return true/false and 'Not Enough Data' if the correct parameters didn't get passed.</p>
  
  <p>My problem is that my AJAX request isn't sending the data that I'm giving it to send.</p>
  
  <p>Here is my JavaScript function:</p>
  
  <pre><code>function confirm_login()
  {
     val_UName = document.login_form.username.value;
     val_Pwd = document.login_form.password.value;
  
     var result = null;
     var scriptUrl = "login_confirm.php";
     $.ajax({
       url: scriptUrl,
       type: 'post',
       data: ({username : val_UName, password : val_Pwd}),
       dataType: 'html',
       async: false,
       success: function(data) {
           result = data;
       }
     });
     result = result.split('|');
     if(result[1] == 'true')
       window.location = "index.php";
     else
       alert('Could not log you in!\n\n'+result[0]);
  }
  </code></pre>
  
  <p>This function is called in the onclick event of the submit button on the form. Now, I've used the debug tools in Chrome and I KNOW that val_UName and val_Pwd are getting the form values. So it's definitely a breakdown between here and the login_confirm.php</p>
  
  <p>Just for completeness' sake, here's what's going on in login_confirm.php (I left out the lines that are connecting to the DB and closing the connection):</p>
  
  <pre><code>$username = mysql_real_escape_string($_POST['username']);
  $password = mysql_real_escape_string($_POST['password']);
  
  if($username == '' || $password == '')
        echo 'Not Enough Data|';
  
  $login_query = "SELECT * FROM users WHERE u_name = '$username' AND pwd = '$password'";
  $result = mysql_query($login_query);
  $result_rows = mysql_num_rows($result);
  
  if($result_rows &gt; 0)
  {
     session_start();
     $row = mysql_fetch_assoc($result);
     $_SESSION['loggedin'] = true;
     $_SESSION['uname'] = $row['u_name'];
     $_SESSION['uID'] = $row['pkid'];
     $_SESSION['email'] = $row['email'];
     $_SESSION['roleID'] = $row['fk_roleid'];
     echo 'true';
  }
  else
  {
     echo 'false';
  }
  </code></pre>
  
  <p>Anyone know what's going on here or seen anything like this before?</p>
  
  <p>PS. I've even tried changing to using GET and that still doesn't work...</p>
