delete cookies [RESOLVED]

[yair24]

hello,
I have 3 pages that deals with cookies:

addcookies.php
<?
$i=0;
$prod=$_COOKIE['prod'];
while (list ($name, $value) = each ($prod))
$i++;

$prod=$_GET['prod'];
setcookie("prod[$i]",$prod);
?>

delcookies.php
<?
$prod=$_COOKIE['prod'];
while (list ($name, $value) = each ($prod))
setcookie("prod[$name]","");
?>

showcookies.php
<?
$prod=$_COOKIE['prod'];
while (list ($name, $value) = each ($prod))
echo "$name == $value<br>\n";
?>

this cookies are holding array as values
I am keep failing to delete all the array there is always one cell in the array that is left...

anybody see something wrong in this code?

if you cant help me base only on this code then tomorrow I will upload it to my server and you will see what I mean...

first you have to set the cookie correcty. you set the name and value but not the time. and deleteing a cookie doesn't mean just delete the value.

to set a cookie you have to do this

setcookie("name_of_cookie", "value_of_cookie", time(),"/");

to delete a cookie you have to do the exact oposite of when you set it. but the only thing that changes is teh time as you do the same time but just minus it.

setcookie("name_of_cookie", "value_of_cookie", -time(),"/");

your way will not work.

Not necessarily. You can delete a cookie just by doing:

setcookie('cooke_name', '', time() - 3600);

You don't have to specify the value or path.

[phpman]

I know but he was deleting the value only with no time.

you should have a path as I have seen many problems arise because the path was forgotten.

why dont they just make a "deletecookie()" function?

I've never had a problem with it.

Why don't ya ask them?

For SETTING the cookie, yes, I agree with you and do understand why you should do that.

For DELETING the cookie, I don't see why you would have a problem with not specifying the path?

[morrowasted]

phpman, you go to htmlforums?

ah, the days of my PHP youth... i'd probably make the same mistake today, actually, if i had never done cookies before!

because it has to be the same as when you created it. so specifing the path should be in there. I guess if you delete it without the path and it works that is fine, I just don't do it that way. if I create it one way I delete it the same way. save all teh trouble.

but the fact remains that he didn't set the cookie correctly anyway.

morrowasted: think about it

If no trouble exists, no trouble can be saved.
