I have created multiple node types for a recent project, that are all pretty much dependant on one another to function as they form a heirarchy.

I've put them all in the same project as seperate modules for the installer, but if I set them up as all dependant on each other, you can never uninstall them. :)

For simplicities sake, is it possible to have multiple node types and the corresponding _hooks for each to be all within one module?

Thank you for your time.

Yes, it's certainly possible. The trick is correctly defining multiple types in hook_node_info().

Here's an example based on a module I'm developing with 2 types:


/**
 * Implementation of hook_node_info().
 */
function synth_products_node_info() {
  return array(
    'synth_product' => array(
      'name' => t('Synthesized product'),
      'module' => 'synth_product',
      'description' => t('Add a new product to the inventory.'),
      'title_label' => t('Short name'),
      'body_label' => t('Details and more information'),
    ),
    'synth_transaction' => array(
      'name' => t('Product transaction'),
      'module' => 'synth_transaction',
      'description' => t('Add a new transaction for a product.'),
      'title_label' => t('Brief description'),
      'body_label' => t('Details and more information'),

    ),
  );
}

You'll notice that neither of the "module" attributes are the same as the name of the module (synth_products.module), so for the node type hooks, I implement functions like: synth_transaction_load() and synth_product_load(), but the usual module hooks are implemented like synth_products_menu().

Note also, that the "module" attribute does NOT have to be the same as the node type. So, all your different node type could get loaded/saved using the same one set of hooks (as the new code in node module does for user-defined types).

I tried what you said earlier in my dev of these modules, but I must have had some errors. Specifically the parts that relate to the main module name versus the individual node types were confusing me. I think I understand now. Thank you.

Ok. Basically I took my three working modules, put all three node types in main_module_node_info(), and copied the rest of the code into the one .module file keeping the same naming.

When I do this, only the hook_block type defined as related to the main_module now will show up in the blocks menu.
The others are not in there anymore...

Can the module define more than one block type?

EDIT: I found my own answer here just after I wrote this. http://drupal.org/node/84213 which references the hook_block api page: http://api.drupal.org/api/HEAD/function/hook_block

What I didn't get before is that the first parameter in the array returned from the 'list' op defines what the DELTA's will be used for later.... now I get it..
