Drupal 7 allows us to add fields to comments; it was not possible to do this in Drupal 6 and earlier versions. Though you can write a custom module, by default Drupal 6 doesn't allow adding of fields in the comments form. In the cooking website, our client wants to add a text field that contains commenter e-mail addresses when they post a comment on the website.
We just learnt how to add a text field to the Cooking Tip content type. In this section, we will create a text field and attach it to the comments form.
