In Chapter 4, we created the Quote content type. Creating new content was easy. The form displayed in Create content | Quote was the same form used by Create content | Page and Create content | Story.

Now, however, we have a more complex content type. We need a form that will display all the biography fields: Biography of (stored as the document's title), Overview (stored in the document's body), Dates, Life, and Works.

To specify how the form for our new content type ought to look, we will implement hook_form(). Drupal will call this hook whenever a user creates a new biography.

In the last chapter, we looked at the Forms API (FAPI) in some detail. Here, we will make use of many of the same features. Since we have seen this API before, I will keep the explanation brief.
