My php host site is runing php 4.4.4 and that is a problem because when i run the script in wamp on localhost there is no problem. But When I got it on the php host, problems popped up. I know there is alot of new function in php 5.02 >
but i don't think that is the problem, or is it?
functions.inc.php
<?php
function redirect($page) {
header('Location: ' . $page);
exit();
}
function check_login_status() {
// If $_SESSION['logged_in'] is set, return the status
if (isset($_SESSION['logged_in'])) {
return $_SESSION['logged_in'];
}
return false;
}
?>
login.inc.php
<?php
require_once('config.inc.php');
require_once('functions.inc.php');
session_start();
// Check if user is already logged in
if ($_SESSION['logged_in'] == true) {
// If user is already logged in, redirect to main page
redirect('../index.php');
} else {
// Make sure that user submitted a username/password and username only consists of alphanumeric chars
if ( (!isset($_POST['username'])) || (!isset($_POST['password'])) OR
(!ctype_alnum($_POST['username'])) ) {
redirect('../login.php');
}
// Connect to database
$mysqli = @new mysqli(DB_HOSTNAME, DB_USERNAME, DB_PASSWORD, DB_DATABASE);
// Check connection
if (mysqli_connect_errno()) {
printf("Unable to connect to database: %s", mysqli_connect_error());
exit();
}
// Escape any unsafe characters before querying database
$username = $mysqli->real_escape_string($_POST['username']);
$password = $mysqli->real_escape_string($_POST['password']);
// Construct SQL statement for query & execute
$sql = "SELECT * FROM users WHERE username = '" . $username . "' AND password = '" . md5($password) . "'";
$result = $mysqli->query($sql);
// If one row is returned, username and password are valid
if (is_object($result) && $result->num_rows == 1) {
// Set session variable for login status to true
$_SESSION['logged_in'] = true;
redirect('../index.php');
} else {
// If number of rows returned is not one, redirect back to login screen
redirect('../login.php');
}
}
?>
First there where no errors when i tried loggin in but after hitting enter it just the blank login.inc.php I get. Then I tried an easy error handling:
function customError($errno, $errstr)
{
echo "<b>Error:</b> [$errno] $errstr";
}
set_error_handler("customError");
at the top of my login.inc.php (After requiere and session_start()😉
Now i got something. There is and undefined index: logged_in. Aha!
So scripts is making an error because i have'nt defined the session and therefore it is returning NULL session.
Then i tried session_is_registred(logged_in) strangly the error messeage disapered but I still get the blank login.inc.php and I am getting pretty blank.
So if there is anyone who can help me out with this problem i will be very greatful.
