This is off the top of my head so do not trust it 100%
<cfscript>
objBlah = CreateObject("component", "Blah").Init();
objBlah.ValidateStuff(FORM);
if(objBlah.GetValidated() IS false) {
WriteOutput(objBlah.GetValidatedMsg());
}
else {
objFoo = CreateObject("component", "Foo").Init();
objFoo.InsertMyStuff(FORM);
}
</cfscript>
So you instantiate the object, within that you have a method named
ValidateStuff and that method requires a structure to be passed in for its
one argument. It does whatever your validation is over that structure and
if any of it fails then within the object it appends to a
Variables.ValidatedMsg and it sets a Variables.Validated flag to false.
Then you have two other methods and they simply return those Variables from
within the CFC. One of those Variables is just a boolean flag to tell you
if validation passed or failed and the other has the failing message.
