Each intranet application you develop must be able to authenticate and autho- rize different types of users. So far, our intranet application framework has the following requirements:. When a user attempts to access an intranet application without logging in first, the application should automatically redirect the user to the login application. Employee access to an intranet application will vary.. Because...

Also note that the database abstraction uses DB.php from the PEAR.. Here, we will cre- ate a class called class.DBI.php that will implement a database abstraction layer for our application framework. Listing 4-1 shows class.DBI.php , which implements the database abstraction using PEAR DB.. See http://pear.php.net/manual/en/core.db.php for details on PEAR DB, a unified API for accessing SQL-databases.. Listing 4-1: class.DBI.php....

Every application needs to display error messages. In the old days, error messages were usually hard-coded in the executable programs and were very difficult to understand, let alone modify!. Error messages written in English are just not friendly enough for the world in this Internet age. So applications that have internationalizable error message support will have broader reach.. Listing 4-2...

If the sample appli- cation is to be used in a different language region, say in Spain, then this file can be modified to create the ES (shorthand for Spanish) language-specific errors by replacing US as ES and also translating the actual error messages.. The sample application then loads the sample.messages file, which is shown in Listing 4-8.. The sample.conf...

Central Authentication System. A CENTRAL AUTHENTICATION SYSTEM consists of two applications: login and logout.. The login application allows users to login and the logout application is used to ter- minate the login session. When such an application starts up, it checks to see if the user is already authen- ticated. If such a user session is found, the user is...

Before you can use the login and logout applications, you need to create the central authentication database and then add a user to it. $AUTH_DB_TYPE = ‘mysql’;. $AUTH_DB_HOST = ‘localhost’;. $AUTH_DB_NAME = ‘auth’;. $AUTH_DB_TBL = ‘users’;. $AUTH_DB_USERNAME = ‘root’;. $AUTH_DB_PASSWD = ‘foobar’;.
