This script will allow you to let people login using a pre-specified login and password. More passwords and logins can be added later, and can when you type in a certain login, you are directed to a specific page only for that login.
If they type in an incorrect user or password, a nice message is displayed teling them to try again.
When you visit the page with this script on it, your IP is temporarily recoded and made into a jpeg which is then displayed on the page. You can choose the font color, size, and background of the jpeg.
ADODB_login is a set of classes and functions (released under the GPL license) that can be used to authenticate a user to a system or application using the excellent ADODB database abstraction layer. The user login function reads md5 hashed passwords from the database. Help on how to implement these classes into your own applications is included in the archive. Happy coding !
