DREAMWEAVER CS3
User Guide
660
The final step in creating a registration page is to make sure the user name is not used by another registered user.
See also
“Build an insert page block by block” on page 633
Add a server behavior to ensure a unique user name (ColdFusion, ASP, JSP, PHP)
You can add a server behavior to a user registration page that verifies that the user name is unique before adding that
user to your database of registered users.
When the user clicks the Submit button on the registration page, the server behavior compares the user name entered
by the user against the user names stored in a database table of registered users. If no matching user name is found
in the database table, the server behavior carries out the insert record operation normally. If a matching user name
is found, the server behavior cancels the insert record operation and opens a new page (usually a page alerting the
user that the user name is already taken).
1
In the Server Behaviors panel (Window > Server Behaviors), click the Plus (+) button and select User
Authentication > Check New Username from the pop-up menu.
2
In the Username Field pop-up menu, select the form text field that your visitors use to enter a user name.
3
In the If Already Exists, Go To box, specify a page to open if a matching user name is found in the database table,
and click OK.
The opened page should alert the user that the user name is already taken and let the user try again.
Building a login page (ColdFusion, ASP, JSP, PHP)
About login pages
Your web application can contain a page that lets registered users log in to the site.
A login page is made up of the following building blocks:
A database table of registered users
An HTML form to let users enter a user name and password
A Log In User server behavior to make sure the entered user name and password are valid
A session variable consisting of the user name is created for the user when the user logs in successfully.
The method you use is identical for ColdFusion, ASP, JSP, and PHP pages. Dreamweaver does not have authenti-
cation server behaviors for ASP.NET pages.
