问题
I have one little problem that dont know how to fix myself. I want to use this logic into my Woocommerce store just for one product.
I have use link like this to autmatically apply coupon code and add to cart:
https://testsite.com/checkout/?add-to-cart=Product_ID&quantity=1&coupon=Coupon_Code
and this seems to work, when quantity is 1. But i want discount (30%) that is automatically placed when click on direct link from before, to make dynamic, for ex:
- Increase quantity to 2 in cart page, and coupon automatically to calculate
2 x 30$ = 60$
discount, - buy 3 from same product, and calculate
3 X 30$ = 90$
coupon discount and so on..
I searched, and found this usefull thread, but there situation is little different then mine.
How can I make to have a specific coupon? Some advice or start point. Thanks

This is possible with that 2 steps:
1) Add a unique coupon with:
- In General settings > Type = Fixed Product discount
- In General settings > Amount =
30
- In Usage restrictions > Products ==> set your desired product(s)
2) Add this code (where you will set your coupon code in the function (in lowercase)):
add_filter( 'woocommerce_coupon_get_discount_amount', 'custom_coupon_get_discount_amount', 10, 5 );
function custom_coupon_get_discount_amount( $rounded_discount, $discounting_amount, $cart_item, $single, $coupon ){
## ---- Your settings ---- ##
// Related coupons codes to be defined in this array (you can set many)
$coupon_codes = array('30perqty');
## ------ The code ------- ##
if ( $coupon->is_type('fixed_product') && in_array( $coupon->get_code(), $coupon_codes ) && $cart_item['quantity'] > 1 ) {
if( in_array( $cart_item['product_id'], $coupon->get_product_ids() ) ){
$discount = (float) $coupon->get_amount() * (int) $cart_item['quantity'];
$round = round( min( $discount, $discounting_amount ), wc_get_rounding_precision() );
}
}
return $rounded_discount;
}
Code goes in function.php file of your active child theme (or active theme). Tested and works.
