Creating a Login Screen

[lyndonlegend]

Hello. I was wondering if someone could point be down the correct path here. I am creating database and tables in mysql through phpadmin. I am assigning users that would be able to update the tables. I want them to be able to update the tables through screens on our website. Therefore, I want them to login and the login be verified as to what they can update. I don't want to hardcode passwords and usernames in my php code. Can someone tell me where I can find examples for this?

Create a form that passes two values to the PHP script.. namely username and password.

Then use the following query: SELECT * FROM user_table WHERE username='$username' AND password='$password'

If MySQL returns any results, let them in. Otherwise, don't.
