CFFTP operation. Variables are usually referenced by "scoping" the variable according to its type, as in Session. varname, or Application. varname. Variable scope ColdFusion supports the Variables scope. Unscoped variables created with the CFSET tag acquire the Variables scope by default. For example, the variable created by: <CFSET linguist = Chomsky> can be referenced as: #Variables. linguist# Client variables These client variables are read-only: Client. CFID Client. CFToken Client. HitCount Client. LastVisit Client. TimeCreated Client. URLToken Server variables Use the Server. prefix to reference server variables: Server. ColdFusion. ProductName Server. ColdFusion. ProductVersion Server. ColdFusion. ProductLevel Server. ColdFusion. SerialNumber Server. ColdFusion. SupportedLocales Server. OS. Name Server. OS. AdditionalInformation Server. OS. Version Server. OS. BuildNumber Application and session variables Use CFAPPLICATION to enable application and session variables. They are referenced as: Application. myvariable Session. myvariable Use CFLOCK to ensure that modifications to shared data occur one after another. See CFML Language Reference description of CFLOCK for details. The predefined application and session variables are: Application. ApplicationName Session. CFID Session. CFToken Session. URLToken 20 CFML Quick Reference Custom tag variables Any ColdFusion custom tag returns the following variables: ThisTag. ExecutionMode ThisTag. HasEndTag ThisTag. GeneratedContent ThisTag. AssocAttribs[index] A custom tag can also set a Caller variable to provide information to the caller. The Caller variable is set as follows: <CFSET Caller. variable_name = "value"> The calling page can access the variable with the <CFOUTPUT> tag: <CFOUTPUT>#Caller. variable_name#</CFOUTPUT> Request variable Request variables store data that pertains to the processing of a single page request. Request variables allow you to store data in a structure that can be passed to nested tags, such as Custom Tags, and processed once. Set a Request variable to provide information to nested tags. The Request variable is set as follows: <CFSET Request. field_name1 = "value"> <CFSET Request. field_name2 = "value"> <CFSET Request. field_name3 = "value"> . . . Each nested tag can access the variable with the <CFOUTPUT> tag: <CFOUTPUT>#Request. field_name1#</CFOUTPUT> Form variable ColdFusion supports the Form variable FieldNames. FieldNames returns the names of the fields on a form. You can use it on the action page associated with a form. Form. FieldNames CFML Quick Reference 21 ColdFusion Tag-Specific Variables A number of ColdFusion tags return data as variables. [. . . ] Searchname is the value of the NAME attribute used in the CFSEARCH operation. searchname. URL searchname. Key searchname. Title searchname. Score searchname. Custom1 and Custom2 searchname. Summary searchname. RecordCount searchname. CurrentRow searchname. RecordsSearched searchname. ColumnList CFSERVLET variables If the WRITEOUTPUT attribute is NO, CFSERVLET returns the text output of the servlet in the following variable: CFSERVLET. Output If the servlet returns any response headers, they are in the CFSERVLET return structure. Each response header can be accessed through a key. In the following syntax, servletResponseHeader is a key, which is the name of the response header set in the servlet: CFSERVLET. servletResponseHeader 26 CFML Quick Reference Standard CGI Variables This is a list of CGI 1. 1 variables many Web servers create when a CGI script is called. NOTE: The CGI variables that are available for your use vary with the Web server and configuration. [. . . ]
