Magento：无法保存属性的选定值（其他属性中使用的制造国属性）

Question

I created dropdown, and changed source_model column in SQL

catalog/product_attribute_source_countryofmanufacture

My new attribute shows country list in backend, but when I select country and save product value disappears.

All parameters of dropdown are same like country_of_manufacture attribute.

What might be a problem for that? I’m using 1.7.0.2 ver.

Answer 1

check whether it returns or not
SELECT * FROM eav_attribute WHERE attribute_code = 'country_of_manufacture';

it's better to create attribute using installer for this you can refer below link
