function _commerce_bpc_get_reference_field_name in Commerce Bulk Product Creation 7

Determine the name of the product reference field (if any) on a node type.

This is used, for example, to determine which field to prepopulate in the node form after bulk creation.

@todo Right now, we simply return the first product reference field we find. What is the best way to deal with multiple product reference fields?

Parameters

object $node_type: The bundle name of the node type for which the product reference field is to be determined.

Return value

string|NULL The machine name of the product reference field, if there is one, NULL otherwise.
