logout to retain the same page

[vikaspa]

dear All

I have typical problem here
refer

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

one can login using following details
user : [e-mail]
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

You'd have to show us the code for the query since that's where the problem seems to be.
