I've been working on a couple modules that modify and enhance the
commenting system (file attachments in comments, and custom comment
validation for specific nodetypes). Another patch
(http://drupal.org/node/14708) would add limited form and validation
customizatoin, but this one adds nodeapi-style form_pre, form_post,
validate, and view hooks.

It's my first patch offered to the Drupal core, hope it's useful.

Found the problem: the patch file had DOS format line-endings. Corrected
in new version: 11.

Patch applies, but captcha is not appearing on comment form (it did
with the older patches, see http://drupal.org/node/14708). Have to
investigate further ....

after some investigation it appears that captcha is expecting a general
'form' $op for the hook, rathre than the 'form_pre' and 'form_post' ops
that this patch supplies.

I added the pre and post operations to mirror the nodeapi form hooks,
I'm not sure that a third general 'form' op would be a good idea. Any
thoughts?

i think consistency with nodeapi is important, so no 'form' operation
... this patch looks simple and useful to me.

+1 for consistency; we can (I will) modify captcha to form_post once
this hits core.

An updated version of the patch with some tweaks. First, the 'form_pre'
and 'form_post' operations have been changed to 'form pre' and 'form
post' to reflect the nodeapi naming conventions.

Second, a 'form param' hook has been added, mirroring nodapi's form
param hook. This allows modules that modify the comment form to
integrate file uploading and other niceties.

In the beginning comments were supposed to be simple texts.. If you add
files, how do you display without 'load' and 'view' operations? If you
add 'load' and 'view', then why not create a 'comment' node type?

------------------------------------------------------------------------

Your point is a good one. I'd like to work on a comprehensive comment
node type rewrite, but this was a 'good enough' solution that helped
out existing modules like captcha and doesn't break existing
comment-based solutions.

the comment file-attachment stuff is just a possible use of some of the
hooks; right now it's impossible. in the future a much cleaner solution
would be nice. i've also used the validation hooks in implementing
debate.module and microfiction.module.

I've checked in a proof of concept module called image_thread that
relies on this patch to provide image uploading in a node's comments.
I'm using it on a small site for photoshop image contests. That module
is rough, but it gives an example of how the new hooks might be used to
provide more complex enhancements.

Important notice: if this gets in, then project module can be overhauled
to use the comment system!
