Cookies?

[Anon]

Hi there,

I'm developing a login-system for my brandnew site. Users may login and then two cookies are saved, one containing username and one with password (md5-encrypted).

I want to make a page for logging out. On that page, I want to "reset" or rather "unset" my cookie. How do I do it? I tried doing this:

1.) setcookie("mycookie");
2.) setcookie("mycookie", "");
3.) setcookie("mycookie", "", 0, "", "", 0);
4.) unset($mycookie);

But they don't work! Giving the cookie another value causes no problem, but I cannot throw-away the cookie!

Can anybody help me? TIA.

Hmmm... there are two things I have to suggest.

First: if you are using PHP3, then you have to keep in mind that all calls to setcookie() are resolved in reverse order. Don't know why, but it's like that. So, if you maybe set that cookie in the same file before deleting it, you should skip the order of the setcookie() calls.

Second: try to set the cookie you want to delete with a time stamp rougly ten seconds later than current time - that should delete it, too.

Here's what I use:

// Delete all cookies
deleteCookies() ;
setcookie("cookie_user","");
setcookie("cookie_passwd","");

// Redirect to the main page
header("Location:http://$HTTP_HOST/$DOCROOT/default.htm");
exit();
?>

Hope that helps...

Hi Chris,

// Delete all cookies
deleteCookies() ;
setcookie("cookie_user","");
setcookie("cookie_passwd","");

What do you mean by deleteCookies()? Is it a PHP function? Coz it's not in the manual. Or do you mean this:

function deleteCookies() {
   setcookie("cookie_user","");
   setcookie("cookie_passwd","");
}

I tried setting a cookie to "", but it didn't work.

Oops,

xcuse the absentmindedness...

here's the function:

function deleteCookies()
{

// delete all the old cookies
for($i=0; $i<$total_items; $i++)
{
setcookie("items_tray[$i]", "");
setcookie("quantity[$i]", "");
}
setcookie("items_tray", "");
setcookie("total_items", "");
setcookie("quantity", "") ;

}

Hope that helps! 🙂

Regards,

Chris
