1. User Authentication with DB Cs346 Fall 2010

2. Requirements Web site is for registered users only – Username and password – Password is encripted

3. Design Database student – Table auth_user – Re-use m12 scripts to create the table MVC – GUI: xhtml for registration entry – PHP: process the input and insert the entry into DB table auth_user – DB: auth_user – GUI: xhtml for existing user login – PHP: process the username-password, query auth_user

4. Development stages

6. Specify name of table and # columns

7. Define field for auth_user

8. Add table ‘auth_user’ to DB ‘student’ The above message was generated by the PHP sript. Is it really true? Use m11 script to list tables
