Hello to all.
Hope everybody is fine. Today I faced a problem that is in our store (www.stylebdonline.com) we dont need the state/province option in billing and shipping option, as we planned this store for Banlgadesh primarily.
First I thought about hide the input from template/persistent/checkout/onepage/billing.phtml but after searching I found that the validation will still there and make your submit invalid. For this reason I dont go with this solution rather search again and found a little solution for this with 2 SQL.
1 update core_config_data set `value`=0 where path = 'general/region/display_all';
1 update core_config_data set `value`= '' where path = 'general/region/state_required';
With running this two sql I can get rid of state/province 🙂
