Cookie Help
I am having problems deleting cookies...

this is how I am setting them, and this is working fine.
PHP Code:
 setcookie("cookie1",$var1,time()+((3600*24)*30),$path,$domain);
setcookie("cookie2",$var2,time()+((3600*24)*30),$path,$domain); 


This is how I am deleting them,..err trying to delete them

PHP Code:
 setcookie("cookie1", $_SESSION[var1], time()-((3600*24)*30));
setcookie("cookie2", $_SESSION[var2], time()-((3600*24)*30)); 


The cookies will not delete. I can update them with new vars with no problem, they just won't delete.

Any help is greatly appreciated.

To delete cookies, you set them with a value of nothing or blank

setcookie("cookie1", $_SESSION[var1], time()-((3600*24)*30));
setcookie("cookie2", $_SESSION[var2], time()-((3600*24)*30));

wont delete them, because your setting a value, you need to do something like this

@setcookie("cookie1", , time()-((3600*24)*30));
@setcookie("cookie2", , time()-((3600*24)*30));

or

@setcookie("cookie1", 0, time()-((3600*24)*30));
@setcookie("cookie2", 0, time()-((3600*24)*30));

depends if your running it on a window or *nix server

here is what I have for my logout page,...

PHP Code:
 session_unset("var1");
session_unset("var2");
session_unset("var3");
session_unset("var4");
session_start();
session_destroy();

setcookie("cookie_var1","",time()-((3600*24)*30));
setcookie("cookie_var2","",time()-((3600*24)*30));

header("Location: index.php"); 


Cookie is still not deleting. Am I doing something wrong here?

try that, that should work, unless you have some funny options turned on your sever,

also as a security note, you shouldnt use cookies for a login area, as they are the far easiest to hack into.

Jason,

What version of PHP are you running? Do you have register_globals set on or off?

What if you were to try:

setcookie("cookie1", "", time()-((3600*24)*30), "", "");

Try resetting the path and domain as well.

This is What I have,...logout.php

PHP Code:
 setcookie("var1","",time()-((3600*24)*30),"","");
setcookie("var2","",time()-((3600*24)*30),"","");

session_unset("var1");
