Logining Out - Session_destroy	View Content

I have coded an 'admin system' that uses sessions. When the user logs out, I don't want them to be able to use the browser's back button to get back into the system. I use the following code for this.

Code: [Select]
<?php
session_start();

$_SESSION = array();

if (ini_get("session.use_cookies"))
{
$params = session_get_cookie_params();
setcookie(session_name(), '', time() - 42000, $params["path"], $params["domain"], $params["secure"], $params["httponly"]);
}

session_destroy();
?>

This works great to make sure someone else can't just walk up to the computer, hit the back button and get into the admin system. The problem is, now no one can login legitimately through the login page either! It seems to disable either sessions or cookies or both.

Any ideas????

Hey phpfreaks,

I have a session, to add words to an array. But my session_destroy() won't work at the end!

This is my code:

Code: [Select]
//at the very top of my index.php
<?php
session_start();
header('Content-type: text/html; charset=UTF-8');
?>

//then some html and javascript code (not affecting my array)
//........
//........

//then my actual form and php code, for adding a word to an array

<form id="arrayForm" method="post" action="index.php">
<input type="text" name="word" maxlength="12" />
<input class="btn" type="submit" name="submit" value="submit" />
<input class="btn" type="reset" name="reset" value="clear array" />
</form>

<p>
<?php
  function sanitize($input) {
   if (!empty($input)) {
    $input = strip_tags($input);
    $input = htmlentities($input);

    return trim($input);
   }
   else {
    return FALSE;
   }
  }

  if (isset($_POST['submit'])) {
   $word = $_POST['word'];

   if (sanitize($word)) {
    $_SESSION['words'][] = $word;
    //display words in array - this works
    for($i=0; $i < count($_SESSION['words']); $i++){
     echo $_SESSION['words'][$i] . " ";
    }
   }
   else {
    echo 'Please enter a word';
   }
  }
  //the below won't work
  elseif (isset($_POST['reset'])) {
   $_SESSION['words'] = '';
   unset($_SESSION['words']);
   session_destroy();
  }
?>
</p>

here is the code
Code: [Select]
<?php
session_start();
/*

*/
require_once '../database/db_connecting.php';
$dbname="sahansevena";//set database name
$con=  setConnections();//make connections use implemented methode in db_connectiong.php
mysql_select_db($dbname, $con);
//update the time and date of the admin table
$update_time="update admin set last_logged_date =CURDATE(), last_log_time=CURTIME() where username='$uname'limit 3,4";
//my admin table contain 5 colums they are id, username,password, last_logged_date, last_log_time
$link= mysql_query($update_time);
// mysql_select_db($dbname, $link);
//$con=mysql_connect('localhost', 'root','ijts');

       $result="select * from admin where username='a'";

        $result=mysql_query($result);
mysql_close($con);
//here i just check after closing data baseconnection whether i do get reselts but i do, why?
echo "after the cnnection was closed";
