Setting Cookies in Javascript, Then Clearing them in PHP

[Gafaddict]

I am using the Tool Man script, a script that allows one to "drag and drop" the position of a list of elements. It uses cookies to pass the information from one page to the next.

 

When I try to use PHP to clear the value of this cookie, it doesn't work.

I have a suspicion that this has something to do with the fact that the cookie was set in JavaScript, because if I try to clear a cookie which I set in PHP, it clears easily.

 

The code I am using to clear is: setcookie("list_boxes", "", time() - 3600);

 

The script that Tool Man uses to set cookies can be found at: http://tool-man.org/source/org/tool-man/cookies.js

 

Any ideas?

There should be no difference in a cookie just because of where it came from.  Have you looked at the actual cookie contents at each stage inside your browser?

 

Another thought is whether the JavaScript is recreating the cookie based on the presence of other cookies or another factor.

You must use the same parameters that were used when the cookie was created. When the parameters don't match, you are trying to clear a different cookie that probably doesn't exist.

 

The set function is setting the path to /. In order to match that cookie, you need to set the 4th parameter in the setcookie() function call to '/'
