Jan 3, 2014 at 21:42 comment added Russell Ormes Having poked around drupal for a week or so now, I also find that the dpm() function from the development module is excellent for seeing the structure of the form fields. I add dpm($form) to my hook_form_alter() implementation and get to see the whole array.

Dec 28, 2013 at 19:46 comment added Russell Ormes Perfect answer, thank you very much. Makes sense to me now. Could this be put somewhere on the module's API page? I am sure it would help a lot of us newbies no end. Is the technique of looking at the _schema() function in an .install file a good one to use for understanding custom fields and entities?
