I've been trying to figure out how to use a CFC for validating form
data, but I can't find any info on how the code should be constructed.
I've been using the CFC and the form variables in the code, but I'm
trying to get away from accessing data directly in the CFC.
The invocation I'm using:
<cfinvoke component = "components.comments"
method =
"validate_comment_data"
argumentCollection = "form"
output = "false"
access = "public"
returnVariable = "form_errors">
Then I just use the CFC like this:
<cffunction name = "validate_comment_data"
displayname = "validate_comment_data"
hint = "Validate comment form data
before inserting or updating"
output = "false"
access = "public">
<cfset form_errors = structNew()>
<cfif not len(trim(form.first_name))>
<cfset form_errors.first_name = "Please enter your first name.">
</cfif>
<cfif not len(trim(form.last_name))>
<cfset form_errors.last_name = "Please enter your last name.">
</cfif>
etc....
<cfreturn form_errors />
</cffunction>
But how would I change the cffunction code to make use of the
argumentCollection = "form"
variables?
<cfif not len(trim(arguments.first_name))> ???
Some clues for the clueless, anyone?
Thanks,
Rick
