retain the same page after logout

[vikaspa]

dear All

 

I have typical problem here

refer

 

http://www.ethnicjewel.in/subcategory.php?cid=13

 

one can login using following details

user : orton@rdiffmail.com

password 12345678

 

and wel come etc details appears

 

when I click on logout it logs out perfectly fine

but

the page cannot be displayed properly as its parameter for query is nullified

and we get following error

 

You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near '' at line 1

 

when i saw address ontop it was

http://www.ethnicjewel.in/subcategory.php

 

and not

http://www.ethnicjewel.in/subcategory.php?cid=13

 

can we avoid this ?

 

script in loout.php

<?php

session_start();

 

 

  session_unregister('Username');

  session_unregister('UserGroup');

 

  unset($_SESSION['Username']);

  unset($_SESSION['UserGroup']);

 

  $loginstatus = 0;

 

  $logoutGoTo = $_SESSION['referpage'];

 

    header("Location: $logoutGoTo");

  ?>

 

I  noticed that the $logoutGoTo has correct page value but the parameter for the query is null

Why not only run the query if $_GET['cid'] is set? Otherwise, echo something like "you need to select a subcat"?

Post your SQL query & content of $_SESSION['referpage']
