is there any update on the "runner class" discussed in the comments?
From what I've read there this would seem to provide the functionality
that I described in my earlier posts on Zend_Validate (which seem to
have been ignored/overlooked :-)).
As I think this component is needed by practically everyone who has to
do form validation and filtering, I'm very interested in seeing this
thing move forward :-)
I agree that some form of runner would make using Zend_Filter /
Zend_Validate much easier to use for certain use cases. The current
implementation is kind of low-level; an application developer needs to
apply each filter or validator independently.
We've done quite a bit of discussion about runners for validators
internally here at Zend. We realized that there are many use cases that
need validation or filtering (filtration?). One common use case is
processing input from web forms, like $_GET and $_POST. But one might
want to filter or validate data that comes from a file, a database, or
user input of other types. One might also want to filter or validate
data that is being output to a database, a file, or user output other
than web presentation. There are also individual cases of using
validators, such as the usage of isHostname() in Zend_Uri_Http. The
application of validation and filtering may be different in these
different use cases.
Because the use cases are so diverse, there may be no single "runner"
solution that solves all of these, and we should not try to make a
single solution.
I suggest that we try to write proposals for solving different use
cases, and treat them as separate components that utilize Zend_Filter
and Zend_Validate. That would be a good way to apply object-oriented
decomposition, and keep Zend_Filter / Zend_Validate classes separate
from the concerns of consumer classes.
I started some notes for a solution similar to the Perl module
HTML::FormValidator, which I used with success on a project some years
ago. I'll write up a brief proposal describing how we might make a
similar solution for Zend Framework.
