mp2: processing a subrequest with HTML::FillInForm

[Stephen Howard <st...@enterity.com>]

I have a form validator PerlResponseHandler (using Data::FormValidator) 
that needs to repopulate a form upon failure.  Problem is, the original 
form is not generated by the handler, but by other pages on the site.  
My thinking is that I ought to be able to do a lookup_uri and pass it a 
filter that can repopulate the html correctly, but the online docs for 
filters is failing me. 

The lookup_uri documentation says that it takes an Apache2::Filter 
object, but nowhere can I find information on how to create one of 
these.  Whatever filter I build I'll need to be able to pass into it 
data specific to the parent request in order to repopulate the html form 
correctly.  How do I do this?

thanks,
- Stephen

Hi Mark,

The other pages on the site are not broken.  I appreciate your attempt 
to identify an underlying flaw, but that is not the case here, and I am 
aware of the vagaries of html parsing (which is why I leave it in the 
capable hands of HTML::FillInForm).

My question is how do I create a Apache2::Filter "object" to pass into 
lookup_uri() when all the filter documentation i've seen suggests that 
filters are subroutines.  I'd love to be able to just pass in a 
subroutine as the second argument to lookup_uri, but none of the 
documentation suggests that as the way to go.

Have you considered fixing the "other pages on the site"?

Pattern-matching HTML that will then be subject to change by
other people on these "other pages" is going to drive you
crazy.  Why not just make the forms do what they're supposed
to do?
