How to create coupon with multiple discount rules

[Kit Shum]

Hi,

I would like to know if there’s any way to create a coupon with multiple discount rules. Currently I need to have the following discount rules:

Cart minimum amount $1000 = 5% off all items on cart (except discount items and category B items)
Cart minimum amount $2000 = 10% off all items on cart (except discount items and category B items)
Cart minimum amount $3000 = 15% off all items on cart (except discount items and category B items)
Cart minimum amount $4000 = 20% off all items on cart (except discount items and category B items)
Cart minimum amount $5000 = 20% off all items on cart (except discount items and category B items)

But to achieve just this alone I had to create 5 separate coupons (we also have another 30 separate coupon rules for our other discounts for the month). Is there any way to group the above discount rules into 1 coupon?

Thank you.

That would need a custom php snippet. Create a 5% discount coupon which excludes discount items and category B items. Add the following snippet to your child theme’s functions.php, replace THE_COUPON_CODE with the actual coupon code.

add_filter('woocommerce_coupon_get_amount', 'custom_tiered_coupon_amount', 10, 2);
function custom_tiered_coupon_amount($amount, $coupon) {
    if (is_admin() && !defined('DOING_AJAX')) return $amount;
    if ($coupon->get_code() !== 'THE_COUPON_CODE') {
        return $amount;
    }
    $cart_total = WC()->cart->get_subtotal();
    if ($cart_total >= 5000) {
        $amount = 20;
    } elseif ($cart_total >= 4000) {
        $amount = 20;
    } elseif ($cart_total >= 3000) {
        $amount = 15;
    } elseif ($cart_total >= 2000) {
        $amount = 10;
    } elseif ($cart_total >= 1000) {
        $amount = 5;
    } else {
        $amount = 0;
    }
    return $amount;
}

That should do the trick. I didn’t test it though.

Hi,

Many thanks that did the trick! One last question what about items based on the quantity purchased?

(e.g.)
buy 2 category A items, those items get 5% off
buy 4 category A items, those items get 10% off
buy 6 category A items, those items get 15% off
etc etc….

Would you be able to kindly provide the custom php snippet for this scenario? Thank you!

I will get back to this…

That may work with a similar script. Create a 5% discount coupon for items in category A and replace the previous snippet with the following snippet.

Replace COUPON_CODE_B with the category B coupon code and replace COUPON_COUDE_A with the category A coupon code.

add_filter(
    'woocommerce_coupon_get_amount', 
    function ($amount, $coupon) {
        if ($coupon->get_code() !== 'COUPON_CODE_B') return $amount;
        if (is_admin() && !defined('DOING_AJAX')) return $amount;
        $cart_total = WC()->cart->get_subtotal();
        if ($cart_total >= 5000) return 20;
        if ($cart_total >= 4000) return 20;
        if ($cart_total >= 3000) return 15;
        if ($cart_total >= 2000) return 10;
        if ($cart_total >= 1000) return 5;
        return 0;
    }, 10, 2
);
add_filter(
    'woocommerce_coupon_get_amount',
    function ($amount, $coupon) {
        if ($coupon->get_code() !== 'COUPON_CODE_A') return $amount;
        if (is_admin() && !defined('DOING_AJAX')) return $amount;
        if (!function_exists('WJECF')) return $amount;
        $n_items = WJECF()->get_quantity_of_matching_products();
        if ($n_items >= 6) return 15;
        if ($n_items >= 4) return 10;
        if ($n_items >= 2) return 5;
        return 0;
    }, 10, 2
);
