Module development and code questions

Hello,

I am developing a Karma module. I need to have an extra field while editing a comment (or adding one). I also need to be able to know what the ENTERED value was (once the user has entered "submit"), in order record it into the database.

Does Drupal allow you to do this?

Thanks,

Merc.

I`ve developed this weather module for learning purposes, and it would probably benefit a lot from some testing.
In case some of you guys want it, it`s free to use/modify/whatever.

Details:
forecasts are fetched from the yahoo weather RSS feed
settings page is not validating country code (checking for existence in yahoo weather location DB)
module is using SimplePie to parse RSS, that means, you'll need to meet it's server requirements.

Im trying to build a form for a module i am working on. No problem, all of my fields show up okay *except* checkboxes and radios. It is fine if I use a single radio button via the 'radio' form type, but when I try creating a set I get no radio buttons at all. I have tried copying and pasting directly from the forms api example page, and it generates the following code for my $form array:

Hello,

I am using 5.x and have named some CCK fields and then changed the labels such that the field names and label do not correspond well.

Does anybody know the steps to change a field name either in Drupal or Directly in DB. I expect I may have to change in several tables of the DB but was not sure.

Thanks in advance
