How to remember (save in cookie) action from user for a day?


New Member
I have created some web-interface. And have created a little preload feature (pre-saver) for it, before logging in interface.Trouble is when user came to this interface he must see pre-saver every time - that's annoying. How to do the pre-saver appear one time in a day?As I understand I must use cookie for that, save some parameter in it? Can I do it via jQuery, or I must use php?I had never worked with cookie before, need your help.Thank you!
