Chapter 22. Web Pages that Manipulate Database Records
| Just displaying database information on a Web page is useful, but you may be more interested in using the Web to collect information from your site's visitors (see Figure 22-1). Maybe something as simple as an online registration form will do the trick. Other times, you may have something more ambitious in minda full-fledged e-commerce system, for example, which doesn't pay the bills unless it provides a way to collect product orders and credit card numbers . Once you've got data in the database, clearly you'll need a way to update and delete that information. After all, prices change, products are discontinued, and you may suddenly want to remove any record of "Harvey the Wise Guy" from your site's online guestbook. Thankfully, Dreamweaver makes changing information in a database simple and painless. Tip: You may feel more comfortable learning these concepts by doing them. If so, turn to the tutorial on Section 22.5 before reading this next section. |
