No idea why I have ran it thru the validator. everything looks good except for it saying that my tags dont match and thats because they are in and out of php i think.


<?php
//clear error message
$error_msg = "";

//if user is not logged in attempt to log in
if (!isset($_COOKIE['user_id'])){
if (isset($_POST['submit'])){

//connect to database
$dbc = mysqli_connect('localhost', 'root', '', 'kickado')
or die('Error connecting to MySQL server.');

//grab login from form input
$user_username = mysqli_real_escape_string($dbc, trim($_POST['user_name']));
$user_password = mysqli_real_escape_string($dbc, trim($_POST['password']));

if (!empty($user_username) && !empty($user_password)){
//compare the input with whats stored in database
$query = "SELECT user_id, user_name FROM kickado_user WHERE user_name = '$user_username' AND" .
"password = SHA('$user_password')";
$data = mysqli_query($dbc, $query);

if (mysqli_num_rows($data) == 1){
//Log in is confirmed set cookies and redirect to home page
$row = mysqli_fetch_array($data);
setcookie('user_id', $row('user_id'));
setcookie('username', $row('user_name'));
$home_url = 'http://' . $_SERVER['HTTP_HOST'] . dirname($_SERVER['PHP_SELF']) . '/index.php';
header('Location: ' . $home_url);
}else {
//username and password are incorrect display an error message
$error_msg = 'Sorry, you must enter a valid username and password to log in';
}
}else {
//username and password are blank display an error message
$error_msg = 'Sorry, you must enter a valid username and password to log in';
}
}
}
?>
