[SOLVED][Drupal CCK] "An error has occurred adding the content type " message is displayed when importing a product type from Ubercart

First let us look at the problem. If you try to export a product directly from Ubercart the array structure will look somewhat similar to this:

$content['type']  = array (
  'name' => 'Product',
  'type' => 'product',
................
.................
  'old_type' => 'product',
  'orig_type' => 'product',
  'module' => 'uc_product',
  'custom' => '0',
[... snip ...]
);

Now the thing is the uc_product module currently does not supply any methods to import the data in the correct format which is likely to be the cause of the error.

Now the solution

• So you have to manually make changes to the the array structure to get it working again.
• The product type should be imported only after changing the 'name', type', 'old_type', 'orig_type' to match the values of the new content type you want to make.
• Next the most important change - Change the value of the 'module' key to 'node'. Some users have reported that this is the only thing you need to do.
• Checkout the following example for product type books

$content['type']  = array (
  'name' => 'Book',
  'type' => 'book',
[... snip ...]
  'old_type' => 'book',
  'orig_type' => 'book',
  'module' => 'node',
  'custom' => '0',
[... snip ...]
);

• Now you can import your new content type
• After successful importing it you will need to set the content type module back to uc_product via MYSQL using the sample code below.

mysql> update node_type set module="uc_product" where type="book";

• If you want to create a new product class you will also need to do the following like this in your db:

mysql> insert into uc_product_classes (pcid,name,description) values ("book id","Name of the book","Description of the book");

• Tip: You can also avoid the error by creating the product content type through Store Administration and then applying the CCK import.

Hope that helps.
