In Part 3 of this tutorial, you learned how to create a form that enables users to post messages to the forum. The insert form has been created using the Insert Record Form Wizard from ImpAKT.

In Part 4, the last part in this series, you will create a similar insert form which also inserts into the message_msg table details about the parent message—that is, the message being replied to—and the original message—that is, the message that started the thread.

You will also learn how to send automatic e-mail notifications to all users who subscribed to a thread when a reply is posted to one of the messages in that thread.

 Note: You can build this application on any of the supported server models—ColdFusion, ASP VBScript, PHP ADODB—using any of the supported databases (including Microsoft Access). The steps are similar. However, for this article, we used PHP 5 and MySQL as the development framework.
