Custom Error Messages - CGI::Applicaiton::Plugin::ValidateRM

[Adam-44]

I have a <textarea> field to evaluate and peg errors line by line.  So
if line 2 and line 5 are invalid, I want to note that as two different
errors.


Can I do this with CGI::Application::Plugin::ValidateRM?


I use an anonymous subroutine as the constraint for the textarea input
so I think that would be the right place to do that.  I see that you get
a Data::FormValidator::Results object passed to the anonymous subroutne
via the constraint, but can I insert multiple error messages with that?


Thanks,
Adam

It is normal for fields to have more than one constraint, with the possiblity
that more than one of them can fail at a time. Usually this is still considered one
constraint with one name, but the error messages get appended together.

If you want separate tokens for each error message, then that's another story.
You could use a field_filter to split the text area into multiple fields before it gets
processed by the constraint_methods, and then define unique constraints for each line.
