Web site design - Chapter 15: E-campaign System 547 Using this checksum
Chapter 15: E-campaign System 547 Using this checksum technique, you can avoid invalid requests from unfriendly users who want to distort the unsubscription tracking data. askForConfirmation() This method displays a confirmation screen to allow the user to confirm that she wants to unsubscribe from this e-mail list. unsubUser() This method uses an unsubscription object, which calls the storeUnsub() method to unsubscribe the user from this list in the database. This user will not receive an e-mail from this list again. Creating a Campaign Reporting Application The campaign report application displays the data collected for each campaign. The user selects the campaign from the main e-campaign interface displayed by the e-campaign user interface application. A sample report is shown in Figure 15-10. Figure 15-10: Sample campaign report.
