Use hook_node_info to setup content types

subscribe

I'm working on multiple issues related to this module today, and will supply a full zip of the changes latter today or tomorrow.

To resolve the installation pain and to ensure the types are always present, I wrote an implementation of hook_node_info() and used hook_enable to create the fields:

<?php

/**
 * Implementation of hook_node_info().
 */
function pageflip_node_info() {
  return array(
    'pageflip_page' => array(
      'name' => t('PageFlip Page'),
      'module' => 'node',
      'description' => t("A page in a %chapter.", array('%chapter' => t('PageFlip Chapter'))),
      'title_label' => t('Title'),
      'has_title' => 1,
      'body_label' => '',
      'has_body' => 0,
      'min_word_count' => 0,
      'locked' => 1,
    ),
    'pageflip_chapter' => array(
      'name' => t('PageFlip Chapter'),
      'module' => 'node',
      'description' => t("A page in a %chapter.", array('%chapter' => t('PageFlip Chapter'))),
      'title_label' => t('Title'),
      'has_title' => 1,
      'body_label' => '',
      'has_body' => 0,
      'min_word_count' => 0,
      'locked' => 1,
    ),
    'pageflip_book' => array(
      'name' => t('PageFlip Book'),
      'module' => 'node',
      'description' => t('A comic book, magazine, or other type of book.'),
      'title_label' => t('Title'),
      'has_title' => 1,
      'body_label' => '',
      'has_body' => 0,
      'min_word_count' => 0,
      'locked' => 1,
    ),
  );
}

/**

function pageflip_enable() {
  module_load_include('inc', 'pageflip', 'pageflip.import');
  module_load_include('inc', 'imagefield', 'imagefield_widget');

Cross posting #915878: Combined issue queue patch

This was fixed a while back.
