the keys in the struct that comprises the argumentCollection are received by
the method as individual cfarguments.
so if your form struct has keys 'firstName' and 'lastName', and the form was
passed in as an argumentCollection, you'd have arguments.firstName and
arguments.lastName.
also you need to var that <cfset form_errors = structNew()>
it also -might- not be a bad idea, if only for documentation purposes, to
specify your cfarguments inside of the cffunction.
so you'd have:
<cffunction name="validate_comment_data" output="false" returntype="struct"
hint="i validate comment form data">
<cfargument name="firstName" type="string" required="true" />
<cfargument name="lastName" type="string" required="true" />
<cfset var errorStruct = structNew() />
<cfif not len(trim(arguments.firstName)) gt 0>
<cfset errorStruct.firstName = "first name is required" />
</cfif>
<cfif not len(trim(arguments.lastName)) gt 0>
<cfset errorStruct.lastName = "last name is required" />
</cfif>
<cfreturn errorStruct />
</cffunction>
