The site I am working on uses banner/popup alerts for emergency situations in the community. I need to set a cookie so the user sees the alert only once, and upon closing the alert won't see it again. However, I need to ensure the user sees any new alerts that may be created, either on the same day or on subsequent days. So the cookie event needs to be per alert.
Currently I'm loading the alert using theme options in the page header. Also, these are site visitors not admin users, so there is no login info to capture.
Thank you.
