  • First, thanks for a great answer. I must add however, that it would have been even better if you had written a book on the subject. :) Between your answer and the references to userpoints_list_transactions, hook_element, & system_element_info, I must have a thousand follow up questions on what those parts are doing. A few basic ones follow: Commented Nov 24, 2011 at 1:38
  • The system_element_info is really nice in that it shows the range of #properties associated with system form elements. Is there more documentation that outlines what is used elsewhere? And how render uses it? Commented Nov 24, 2011 at 1:41
  • You're right, I am a bit confused by your statement that I need to enter the content into the node. In your render array example above you have text in the child element, and a table with content in $rows. The content I want to place will have similar sections of paragraphs, lists and tables all within a single body field. Commented Nov 24, 2011 at 1:48

    If you have follow-up questions, it's best to create separate questions and refer to this one, comments don't work well for long explanations. A render array is basically a subset of a $form definition, so you can use the form api documentation api.drupal.org/api/drupal/…. Commented Nov 25, 2011 at 20:40

    And yes, as I said, you can not store render arrays, that just doesn't make sense. You only have two options, creating a number of fields which only works if your structure is static. If you have dynamic, complex content structures, you really only have one choice. Write it in the body or another text field. As HTML. Render arrays are designed to convert data structures into something that can be rendered to HTML but still be altered/themed differently. Commented Nov 25, 2011 at 20:41
