I am in the process of trying to convert the ezmlm module to the new forms API. I am doing this so I can learn the forms API. I am one of the maintainers of the ezmlm module and it is a very, very simple module. Once I learn the forms API fairly well, I will be happy to help other people with their conversion efforts, write more documentation on the API and/or convert more modules. I just need to get it all clear in my head first. However, I'm having some problems converting a simple form in my module. I spent several hours reading all the latest documentation and working on it last night, and I've run into a few things where I am not clear on how it should work. If anyone is willing to give me some help, you can view the before and after code here: http://phpfi.com/82366 Questions: 1. Is the #action key in the first form[] element the right way to specify where to post the form? 2. What's the proper array element index where it says "WHAT_GOES_HERE" for a non-form item message that needs to be injected into the form at that point? Is #markup the right type? Seems like it is. 3. What's the correct #type for my hidden form element? 4. What's the correct form array secondary index for an array of checkboxes? In the old form API, one used names like 'my_checkbox_list][' in order to generate HTML like this: <input type="checkbox" name="edit[my_checkbox_list][]"> How is that done with the new API? Thanks, Chris Johnson 31 hours until I leave for Amsterdam! :-)
