Price Field Type from the Commerce module package is not exportable for Feeds. So as a work-around, I saved my prices ('min price', 'hot price' and "deposit price') into normal Float fields and just move the values to the Price Field Types on-the-fly. And so here it is (set using Rules: After an item is saved of content type 'Property'):
$node->field_price_amount['und']['value'] = [node:field-current-price-temp]; $node->field_hot_price_amount['und']['value'] = [node-field-hot-price-temp];
and then applying the node_save($node) with $node->is_new set to FALSE.
All the other values are saving properly except for the field type defined by the Commerce module. No actual data saved to tables at all.
"$node->field_price" should be the right machine name I have defined for this field. But for some reason importing leads to error field_price_amount cannot be NULL. This is also weird. So I changed it to field_price_amount so it won't complain but still not saving despite no more errors in importing. (The db table is still named field_data_field_price but for some reason it is complaining as 'field_price_amount should not be null ).
Anyone have ideas?
