How to add Remember Me In Login Functionality
That would be done client side using JavaScript and a cookie.
It doesn’t have to be client side. You can use PHP to set the timeout of a cookie to a really long integer whenever the user selects the Remember Me checkbox.
Usually it’s done server-side, by setting a cookie after the user is successfully logged in. There’s some example PHP code here, but I’d recommend reading [URL=“http://fishbowl.pastiche.org/2004/01/19/persistent_login_cookie_best_practice/”]this article first.
I’d avoid using JS for this sort of functionality, as some users may have it disabled in their browsers.
