checking for successful login

[droidus]

I am trying to check if the user is successfully logged in. here is my code:

"loginUser.php",
    				{ 
        				username: $("#username").val(), password: $("#password").val() 
        			},
    				function(data){  
        				$("#loginStats").html(data);
						var success = (data == true ? $('#login').html('<img src=images/loader.gif width=16 height=16 /> Now taking you to the member area...') : $('#login').html('<img src="images/red_x.png" width="24" height="24" /> Invalid Login.')); 
						if(success) {
							
						}
        			}

loginUser.php

foreach($_GET as $key => $value) {
	$get[$key] = $value;
}

$username = $get['username'];
$password = $get['password'];

if(!empty($username) && !empty($password)) {
	return true;
} else {
	return false;
}
}

i enter values for both fields, but it is still returning false - invalid login. why?

remove

var success = (data == true ? $('#login').html('<img src=images/loader.gif width=16 height=16 /> Now taking you to the member area...') : $('#login').html('<img src="images/red_x.png" width="24" height="24" /> Invalid Login.')); 
						if(success) {
							
						}

insert

var content = (data == true) ? '<img src="images/loader.gif" width="16" height="16" /> Now taking you to the member area...' : '<img src="images/red_x.png" width="24" height="24" /> Invalid Login.';

$('#login').html(content);

what does this do?

foreach($_GET as $key => $value) {
    $get[$key] = $value;
} 

try this one

$username = $_GET['username'];
$password = $_GET['password'];

if(!empty($username) && !empty($password)){return true;}
else{return false;}

hm, stll always returns false, even if i fill in values, or set values in the loginUser.php page...

here is my code for each page:

$.get
    			(
    				"loginUser.php",
    				{ 
        				username: $("#username").val(), password: $("#password").val() 
        			},
    				function(data){  
        				$("#loginStatus").html(data);
						
						var success = (data == true) ? '<img src="images/ajax-loader.gif" width="16" height="16" /> Valid Login!  Now taking you to the members area...' : '<img src="images/red_x.png" width="24" height="24" /> Invalid Login.  Please try again.';

						$('#loginContainer').html(success);

						if(success) {
							// do something here, like log them in - update db, set cookies, and redirect
						}
        			}
    			)

<?php

include 'db_connect.php';
$username = $_GET['username']; 
$password = $_GET['password']; 

if(!empty($username) && !empty($password)){return true;} 
else{return false;} 

?>
