logout confirmation

verN

hi,

i have the following code that enables a user to be logged out. This works perfectly however i now wish a confirmation dialog to appear asking to user to confirm thier actions but how do I do this in this code:

<?php
   session_start();
   session_destroy();


   $logout = "login.php";		
   header("Location: $logout");

?>

thanks in advance

Create a new page, let's say "login_confirm.php"...

Simply write :

Are you really sure you want to logout?

Yes -> logout.php
No -> another_page.php

Logout being the code you wrote above...

isn't there a way i could use it on the same script

Of course...

<?php
 if(isset($_GET['logout'])) {
   session_start();
   session_destroy();


   $logout = "login.php";        

   header("Location: $logout");
   exit();
 }
 echo 'Are you sure you want to logout?' . "\n";
 echo '<p>' . "\n;
 echo '    <a href="' . $_SERVER['SCRIPT_NAME'] . '?logout=1">Yes</a> | <a href="another_page.php">No</a>
 echo '</p>' . "\n;
?>

isn't there a way to do this with javascript since it will be alot neater
<?php
session_start();
session_destroy();

// redirects the user
//$logout = "login.php";
//header("Location: $logout");
//exit();

?>
<script language="javascript">
function confirmlink(link) {
if ( confirm("Are you sure you want to log out?"))
window.location = "login.php";
}
</script>

thanks

Yes...

<a href="logout.php" onclick="return confirm('Are you sure ?');">Logout</a>

Will work as long as someone has JavaScript activated. Otherwise, it will log out without confirmation.

it doesn't work it takes the user back to login page without confirming.

<?php
   session_start(); 
   session_destroy(); 


   $logout = "login.php";         

   header("Location: $logout"); 
   exit(); 


?>
<script language="javascript">
function confirm() {
    if ( confirm("Are you sure you want to log out?"))
      window.location = "login.php";
}
</script>

No, the JavaScript stuff needs to be put in a NORMAL webpage, not in the logout page !

Look at your code... you wrote header("Location: ..."), and then exit() ! How do you want the rest of the code to be executed after calling exit() ?!

When I wrote the little link above, I had in mind you would put it in every page of your site, just like on many forums where there's always a logout button !

Also, you can't create a JavaScript function confirm() since there's a built-in function with that name...
