> Can this be done?
Create a "Validator" CFC.
This would contain the structure (preferrably an array of structs) that
holds all the errors plus a method (like validateForm) that does each of
the validations and populates the error info. Then you would also have a
method (like errorDisplay) that would take all of the errors stored and
then return an appropriate string for rendering in whatever area you have
your error output.
Like (not tested):
<CFCOMPONENT>
<CFSET this.errors = ArrayNew(1)>
<CFFUNCTION name="validate">
<!--- check a field here - need parameters for the method
--->
<!--- call addError if there is something wrong --->
</CFFUNCTION>
<CFFUNCTION name="addError">
<!--- creates an error struct and adds it to the
this.errors array --->
</CFFUNCTION>
<CFFUNCTION name="getErrors" returnType="string">
<!--- create an empty string to return --->
<!--- loop over the array of errors - concatenate whatever
output you want to produce --->
<!--- return the string - if the string is empty there are
no errors (alternative would be to have an HasErrors method ---->
</CFFUNCTION>
</CFCOMPONENT>
Then what you could do is subclass this component and override the
"getErrors" method to render the errors in different ways for different
situations.
