PHP Code from JavaScript ???

Anon

Can I call a php function built-in or own-created, from a javascript function ?

I mean, I want to delete a cookie(setcookie - php function) when unloading a window. On closing the window, javascript unload event is triggered in which i want to delete the cookie.
If there any alternative method to delete a cookie on closing the browser window, please let me know.

The javascript document.cookie with the same name of the php given cookie has NO effect on cookies.
Basically, my main problem is that Cookie exists even if my browser window is closed. I don't want to keep it active, for security reasons.

Any idea how to do it ? i think a combination of Javascript with PHP should work, but how ?

Thanks.

Here is a little javascript for deleting a cookie:

function DeleteCookie (name,path,domain) {
if (GetCookie(name)) {
document.cookie = name + "=" +
((path) ? "; path=" + path : "") +
((domain) ? "; domain=" + domain : "") +
"; expires=Thu, 01-Jan-70 00:00:01 GMT";
}
}

Note: path and domain are both optional. All you need to pass the function is the name of the cookie.

Or, alternatively, you could use the onunload to open another window notifying them that they have logged out of the site, which is also a php script that deletes the cookie. Hope that helps!

Chris,

I am getting object expected error from the code, i borrowed from you. I am calling a function forumClose where i place your if GetCookie code...

any idea what's wrong ?

Why not simply set the expiry date for the cookie to 0. That way when your session (browser closes) finished the cookie will automatically expire

Thanks Gary,

That was a simple but very effective solution in getting rid of cookie. I somehow forgot the significance of 0 in cookie. I had time based earlier, it just didn't get expired at all till the expiry time had reached.

Thanks
