Define PHP server variables
Define server variables as a source of dynamic content for PHP pages. The PHP server variables appear in the Bindings panel.
1. Open the Bindings panel (Window > Bindings).
2. Click the Plus (+) button, and select the variable from the pop-up menu.
3. In the Request Variable dialog box, enter the name of the variable (for example, REQUEST_METHOD), and click OK.
For more information, search for the keyword $_SERVER in the PHP documentation.
Define a ColdFusion client variable
Define a ColdFusion client variable as a source of dynamic content for the page. The newly defined ColdFusion client variables appear in the
Bindings panel.
In the Client Variable dialog box, enter the name of the variable, and click OK.
For example, to access the information in the Client.LastVisit ColdFusion variable, enter LastVisit.
Client variables are variables created in the code to associate data with a specific client. Client variables maintain the application’s state as the
user moves from page to page within the application, as well as from session to session.
Client variables can be user-defined or built-in. The following table lists the built-in ColdFusion client variables:
Variable Description
Client.CFID An incremental ID for each client that connects to the server.
Client.CFTOKEN A randomly generated number used to uniquely identify a
particular client.
Client.URLToken A combination of CFID and CFTOKEN to be passed between
templates when cookies are not used.
Client.LastVisit Records the timestamp of the last visit made by a client.
Client.HitCount The number of page requests tied to a single client (tracked using
CFID and CFTOKEN).
Client.TimeCreated Records the timestamp when CFID and CFTOKEN were first
created for a particular client.
Define a ColdFusion cookie variable
Cookie variables are created in the code, and access information contained in cookies passed to the server by a browser. The defined cookie
variable appears in the Bindings panel.
In the Cookie Variable dialog box, enter the name of the cookie variable, and click OK.
Define a ColdFusion CGI variable
The defined CGI variable appears in the Bindings panel.
In the CGI Variable dialog box, enter the name of the variable, and click OK.
For example, if you want to access the information in the CGI.HTTP_REFERER variable, enter HTTP_REFERER.
The following table lists the most common ColdFusion CGI variables that are created on the server:
Variable Description
SERVER_SOFTWARE The name and version of the information server software
answering the request (and running the gateway). Format:
name/version.
SERVER_NAME The server's hostname, DNS alias, or IP address as it appears in
self-referencing URLs.
GATEWAY_INTERFACE The revision of the CGI specification to which this server
complies. Format: CGI/revision.
SERVER_PROTOCOL The name and revision of the information protocol this request
came in with. Format: protocol/revision.
