PHP won't return a response

Question

It's probably something really basic but I've been at it for a while and it's not jumping out at me and I guess I'm tired...please help.

I'm trying to create a simple login html page, read it using jquery/ajax and have php verify it. Here are the 2 pieces the javascript/jquery and the php. While firebug seems to correctly report that "message" is being set, nothing comes back as response...what am I doing incorrectly? And if php did report an error, where do I look for it?

login.js

$(document).ready(function(){  
    $('#loginForm').submit(function(){  
        var usern=$('#username').val();  
        var pword=$('#password').val();  
       $.ajax({  
            url: 'mylogin.php',  
            data: 'action=login&usern='+usern+'&pword='+pword,  
            dataType: 'json',  
            type: 'post',  
            success: function (j) {  
                $('#loginmessage').html(j.msg);  
            },  
       });  
    });  
});`

mylogin.php

<?php   
    $username=$_POST['username'];  
    $password=$_POST['password'];  
    $retval['msg']="in mylogin.php";  
    fb($retval,"return output from login");  
    echo json_encode($retval);  
?>

Answer 1

Its very simple you are posting your username as usern and password aspword

So it should be

<?php   
    $username=$_POST['usern'];  
    $password=$_POST['pword'];
