Questions tagged [cffunction]

is used in ColdFusion Markup Language (CFML) to create user defined functions.

<cffunction> is used in ColdFusion Markup Language to create user defined functions. The basic syntax is

<cffunction name="myFunc" returntype="string" output="false">

  <cfreturn "Hello, World!">
</cffunction>

Functions may be created as a global function or as apart of an object (cfc). Functions typically include business logic and not presentation logic.

Functions can also be defined in <cfscript> via

string function myFunc() output="false" {
   return "Hello, World!";
}
