Thank you for the clarification.
Anyway, I seem to remember that I tried setting 21 as $config[‘defaults’][‘shipping’][‘tax_rate’] and it did not work as expected.
I’m setting it to false now, so it should use the cart tax value, plus I’m manually setting ‘tax_rate’ when calling set_shipping, too.
Here goes about orders:
Note that discount_methods, types and tax_methods are default.
I added a new 10% code:
INSERT INTO `flexi_discounts`(`disc_id`,`disc_type_fk`,`disc_method_fk`,`disc_tax_method_fk`,`disc_user_acc_fk`,`disc_item_fk`,`disc_group_fk`,`disc_location_fk`,`disc_zone_fk`,`disc_code`,
`disc_description`,`disc_quantity_required`,`disc_quantity_discounted`,`disc_value_required`,`disc_value_discounted`,`disc_recursive`,`disc_non_combinable_discount`,`disc_void_reward_points`,
`disc_force_ship_discount`,`disc_custom_status_1`,`disc_custom_status_2`,`disc_custom_status_3`,`disc_usage_limit`,`disc_valid_date`,`disc_expire_date`,`disc_status`,`disc_order_by`)
VALUES (1,2,7,1,0,0,0,0,0,‘TEST’,‘Test description’,0,0,0.00,10.00,0,0,0,0,‘0’,‘0’,‘0’,5,‘2012-11-12 14:50:20’,‘2012-11-22 14:51:55’,1,100);
disc_type_fk = 2, Summary Discount
disc_method_fk = 7, Summary Item Total - Percentage Based
disc_tax_method_fk = 1, Apply Tax Before Discount
var_dump($this->flexi_cart->cart_contents());
output:

The order total (last line) is correct, as it is (99.99 + 17.83 - (99.99*0.10)).
I don’t understand where that €25.61 in savings is coming from.
About custom statuses: I understood how they work, but they directly relate to the current user session and not to the cart contents.
For example, I’d like to be able to set a discount for a specific brand, for a specific category of products, for a group of users based on some filters (i.e. users that didn’t buy anything in the last 30 days), etc.
I think the best way to achieve this would be to add custom fields to the ‘discounts’ table (or a new table with a fk), then manually check cart contents and querying the db for a discount that matches these filters.
Do you think it would be a viable solution?
About enabling joins: let’s say I want to offer free shipping to users in the UK. I see you do that in the examples.
I disabled the ‘flexi_locations’ table since I’m using one of my own (not used by flexi anyway, as I use my own calculate_shipping() method).
How do I setup a join for my own locations table?
Sorry about the length of this post (and this discussion), I hope it will be useful for everyone
