Hey,

A friend of mine edited the script to display an error inline via PHP rather than the JavaScript popup "wrong Password..." replace the JavaScript <script></script> tags with the following...

PHP Code:


			
exit;

    } 

    else {

        $error="Wrong password, please try again.";

    }

}

?>

then place anywhere in the page you want the error to show up:

PHP Code:


			
<?

    if(strlen($error) > 0) {

        print "

        <p style=\"border: 1px dotted #000; padding: 4px; background-color: #FFFFE6;\">".$error."</p>";

    }

    ?>

I found the <script></script> tags above the Doctype causing issues in IE

I'm using a script that is similar to this one and it works perfect. Only recently a problem raised when going to one of the new pages I created.

The file is located in the same folder as the one I'm directing the people from,
it's source:

PHP Code:


			
<?php

session_start();

if (empty($_SESSION['ingelogd']) || $_SESSION['ingelogd'] != true)  {

    header('Location: ../login.php');

    exit;

} else { ?>

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">

<html xmlns="http://www.w3.org/1999/xhtml">

<head>

<meta http-equiv="Content-Type" content="text/html; charset=utf-8" />

<title>Untitled Document</title>

</head>

<body>

<pre>

<?php print_r($_SESSION); ?>

</pre>

</body>

</html>

<?php } ?>

The check is exactly the same as on all the other pages I created but each time I go to this page the array is empty and I'm sent back to the login-page. (I tried without redirecting, just by using session_start(); and failed aswell)

I even tried by using the code of one of the other (working) pages but without result.
This all on the hosted site.

When I try to access the page on my loal machine there is no problem.

Does anyone have a clue?

PHP Code:


			
<?php session_start();

$host = 'localhost';

$database = 'my_database';

$dbuser = 'db_username';

$dbpassword = 'db_password';



$db_conn = mysql_connect($host, $dbuser, $dbpassword) or die('Not connected : ' . mysql_error());





if(isset($_POST['username']) && $_POST['username'] != ''){

   if(isset($_POST['password']) && $_POST['password'] != ''){

       mysql_select_db($database, $db_conn);

       $query_rs_userdetails = "SELECT * from `users` WHERE userid='$_POST['username']' AND password = '$_POST['password']' LIMIT 1": //I limit it allways to 1 to be sure I only get 1 or 0 results

       $rs_userdetails  = mysql_query($query_rs_userdetails, $db_conn) or die(mysql_error());

       $row_rs_userdetails = mysql_fetch_assoc($rs_userdetails);

       $totalRows_rs_userdetails = mysql_num_rows($rs_userdetails );



       if($totalRows_rs_userdetails  == 1){

             $_SESSION['myloggedstate'] == true;

             // set any other session parameter you want to set with the result here (like the emnail-address etc)



            $location = 'inlogged_page.php';

      } else {

            $location = 'not_inlogged_page.php';

     }

      header('Location: '.$location);

      exit();

   }

}

.......html of the page

I hope this is helpfull

Ok, I think I've got myself into a corner on this one. Just came across your script the other day and started playing with it. On the login.php page I changed the "index.php" to the html page I was using. It works fine on my Mac but on my boss's PC just loops him back to the login.php page.

I changed index.php to directory.php, then changed my index.php page to directory.php as well, to which I added my html. same result. Other than that I haven't changed anything. Have any idea what I might be doing wrong?
Thanks!

Make sure the variable in the session you check looks for is mentioned in the page you are headering to:

PHP Code:


			
if($totalRows_rs_userdetails  == 1){ 

             $_SESSION['myloggedstate'] == true; 

             // set any other session parameter you want to set with the result  here (like the emnail-address etc) 



            $location = 'inlogged_page.php'; 

}

on the new page the checked must be:

PHP Code:


			
session_start(); 

if (empty($_SESSION['myloggedstate']) || $_SESSION['myloggedstate'] != true)  { 

    header('Location: ../login.php'); 

    exit; 

} else { 

?>

rest of page
