[Solved] Drupal Commerce - Programagical types and products.

Hi All,

i have a need to programmatically create a product type on install, and then create products based on user content. Right now, im stuggling with getting the product type to work, here is the code i have for product types:

/**
* Implements hook_install().
*/
function cg_commerce_signs_install() {
  drupal_static_reset();
  commerce_product_configure_product_types();

  $product_type = commerce_product_ui_product_type_new();

  $product_type['type'] = 'commerce_sign';
  $product_type['name'] = t('Commerce Sign');
  $product_type['description'] = t('A commerce sign product type.');
  $product_type['is_new'] = TRUE;

  commerce_product_ui_product_type_save($product_type, TRUE);
}

and for generating a product (in the module file) - This works fine, it gets stored in the database, but never shows yup as the type its assigned to doesn't exist.:

/**
 * Create a product programmatically.
 */
function cg_commerce_signs_create_product($product_type, $extras) {
  // Generate a new product object
  $new_product = commerce_product_new($product_type);

  $new_product->status = $extras['status'];
  $new_product->uid = $extras['uid'];

  $new_product->sku = $extras['sku'];
  $new_product->title = $extras['title'];
  $new_product->created = $new_product->changed = time();

  commerce_product_save($new_product);
  return $new_product->product_id;
}

the process i need to complete is:

On install build product type.
In the admin area, create products assign prices etc
On save of user content, generate a product variant that can be bought via the checkout.

Something like vistaprint where you have a product that you can customise and then buy.

does anyone have any pointers on what im missing here? - the first time i've used commerce API..

Thanks
