Hi.

What have you tried so far?

We are always happy to help, but we are not about to do your work for you. You are at least going to have to try it yourself, and if you run into something you need help with, we will need to know what you are doing and how it isn't working. Error messages and code samples are very helpful to.

1. You get the data from the database and display it.

2. When a user logs in, you must be setting a session or cookie. Therefore, to log the user out, simply destroy the cookie or session.

sreenisha, what you're asking is a rather complicated question and requires a rather complicated answer.

Markus is right, you're going to need to interact with a database to compare user name and password against. If the information matches, you'll want to save a piece of authentication information in their browser called a cookie.

Next, on the pages you want to display this welcome block, you'll check for the cookie, make sure it's valid (by comparing it with the database,) and then display the block.

If you want me to give you a simply example just get a hold of me and I'll write up something simple for you to get you on your way! :)

Please do not offer programming help through emails or private messages. Help offered on the forum is better because it benefits everyone else facing similar problems. (See How To Respond To A Question).

Having said that, I actually wrote an example as a part of my PHP Session HowTo that might help. It's very simple but might help point in the right direction.
