Example: loginform.cfm
The loginform.cfm page consists of the following:
Description
Runs if the user submitted a login form.
Tests to make sure that both name and password have data. If either
variable is empty, displays a message, followed by the login form.
The tag prevents processing of any code that follows on this
cfabort
page.
Runs if the user submitted a login form and both fields contain data.
Uses the cflogin structure's
user record in the database and get the user's roles.
If the query returns data in the Roles field, logs in the user using the
user's name and password and the Roles field from the database. In
this application, every user must be in some role.
Runs if the query did not return a role. If the database is valid, this
means there was no entry matching the user ID and password.
Displays a message, followed by the login form.
The tag prevents processing of any code that follows on this
cfabort
page.
Ends the loginquery.Roles test code.
Ends the form entry empty value test.
Ends the form entry existence test.
Ends the
cflogin
If a user is logged-in, displays the Logout button.
If the user clicks the button, posts the form to the application's
(theoretical) entry page, index.cfm.
Application.cfc then logs out the user and displays the login form. If
the user logs in again, ColdFusion displays index.cfm.
Ends the onRequestStart
Ends the Application component.
