Define session variables
You can use session variables to store and display information maintained for the duration of a user’s visit (or session).
The server creates a different session object for each user and maintains it for a set period of time or until the object is
explicitly terminated.
Before defining session variables for a page, you must create them in the source code. After you create a session variable
in the web application’s source code, you can use Dreamweaver to retrieve its value and use it in a web page.
1 Create a session variable in the source code, and assign a value to it.
For example, this ColdFusion example instantiates a session called username, and assigns it the value Cornelius:
2 Select Window > Bindings to display the Bindings panel.
3 Click the Plus (+) button, and select Session Variable from the pop-up menu.
4 Enter the name of the variable you defined in the application’s source code, and click OK.
Define application variables for ASP and ColdFusion
In ASP and ColdFusion, you can use application variables to store and display information that is maintained for the
lifetime of the application and persists from user to user. After you define the application variable, you can use its value
in a page.
Note: There are no application variable objects in PHP.
1 Open a dynamic document type in the Document window.
2 Select Window > Bindings to display the Bindings panel.
3 Click the Plus (+) button, and select Application Variable from the pop-up menu.
4 Enter the name of the variable as defined in the application’s source code, and click OK.
The application variable appears in the Bindings panel under the Application icon.
