Clear Cookies

Hello again.

I am trying to make a button to clear all cookies (partner_id primery).
i used this code in a blank module (PHP enabled):

function deleteCookies()
{
if (isset($_SERVER)) {
$cookies = explode(';', $_SERVER);
foreach($cookies as $cookie) {

$parts = explode('=', $cookie);
$name = trim($parts[0]);
setcookie($name, '', time()-1000);
setcookie($name, '', time()-1000, '/');
}
}
echo '<script type="text/javascript">';
echo 'alert("Cookies Deleted!")';
echo '</script>';

}

echo '<input type="button" onClick="'.deleteCookies().'" value="Clear Cookie" /><br>';


but when i am runing it, it does not clear the most importent cookie, the partner_id..
So i am asking, can something close to this can be done to clear the partner_id cookie?

thanks alot.

thanks for replay.
I checked again and both $_COOKIE and $_SERVER contains only the basic joomla cookies.. not login info,hikashop, languague or anything else (__utma,__utmb...), i guess because this is external page without joomla authentication.. (blank module display the same cookies with $_SERVER).

I elso cannot use $_COOKIE at the blank module because i cannot start session in there..

Any ideas?

Ok now i know why that happened.. thanks

I cant use form because i need link that will do the clearing (unvisible link), although i changed to form to see and it is working, but still the cookies that are being cleaned are the basics, and not hikashop_affiliate..

I got no ideas what to do, so i can see all of my website cookies...
