Question

I have a web php web site. I want to show a message on the pop up div when a user browse my site (home page). I need to show the message only the first time with in a browser.
Does anyone know?

Answer 1

There is no php in your question, it is only js and cookies.

The logic you want is:

• Does cookie <name> exist?
• yes
  • The user has been to your page/site before
  • do nothing
• no
  • The user is new
  • write cookie <name> with any value
  • run your “display message” function
