I am looking for a tutorial for a an Announcement style app.

 

I am using php and MySql and am guessing that I will need to use Javascript or MooTools or something similar.

 

I would like a div that displays a message when a user logs in, however the message will disappear when they click the x icon. No further messages will be displayed until I add a new one into the database.

 

I have tried googling, but don't know what this type of app/script woiuld be called.

 

Could somebody point me in the right direction please?

I wouldn't use Javascript. I would use PHP, so when they click on the close link it loads a script to create a cookie. Then the page with the announcement can check if the cookie exists or not, if it does, don't show the announcement, otherwise do.

 

You could use a MYSQL database but cookies are adequate. If you don't want the page to reload you'll need to use Ajax. Although you should be able to create cookies with basic Javascript.
