Do not give discounts on certain product categories when choosing “local pickup” in WooCommerce

Question

I use a code that adds a 20% discount when choosing "Local Pickup" in the cart and at checkout based on Do not give discounts for on sale products when selecting “local pickup” in WooCommerce

/**
* Discount for Local Pickup
*/
add_action( 'woocommerce_cart_calculate_fees', 'custom_discount_for_pickup_shipping_method', 10, 1 );
function custom_discount_for_pickup_shipping_method( $cart ) {
    if ( is_admin() && ! defined( 'DOING_AJAX' ) )
        return;

    $percentage = 20; // Discount percentage

    $chosen_shipping_method_id = WC()->session->get( 'chosen_shipping_methods' )[0];
    $chosen_shipping_method    = explode(':', $chosen_shipping_method_id)[0];

    // Only for Local pickup chosen shipping method
    if ( strpos( $chosen_shipping_method_id, 'local_pickup' ) !== false ) {

        // Set variable
        $new_subtotal = 0;

        // Loop though each cart items and set prices in an array
        foreach ( $cart->get_cart() as $cart_item ) {

            // Get product
            $product = wc_get_product( $cart_item['product_id'] );

            // Product has no discount
            if ( ! $product->is_on_sale() ) {
                // line_subtotal
                $line_subtotal = $cart_item['line_subtotal'];

                // Add to new subtotal
                $new_subtotal += $line_subtotal;
            }
        }

        // Calculate the discount
        $discount = $new_subtotal * $percentage / 100;

        // Add the discount
        $cart->add_fee( __('Discount') . ' (' . $percentage . '%)', -$discount );
    }
}

Tell me how to make sure that the local-pickup discount is not taken if the product is from certain categories? I must specify the category name manually, for example, "steak", "sauce" and "bread".

And how to make a notice to customers "Pickup discount does not apply to products from the" Category Name "category"?

I will be glad for your help!

Try below code

/**
* Discount for Local Pickup
*/
add_action( 'woocommerce_cart_calculate_fees', 'custom_discount_for_pickup_shipping_method', 10, 1 );
function custom_discount_for_pickup_shipping_method( $cart ) {
    if ( is_admin() && ! defined( 'DOING_AJAX' ) )
        return;

    $percentage = 20; // Discount percentage

    $chosen_shipping_method_id = WC()->session->get( 'chosen_shipping_methods' )[0];
    $chosen_shipping_method    = explode(':', $chosen_shipping_method_id)[0];
    

    // Only for Local pickup chosen shipping method
    if ( strpos( $chosen_shipping_method_id, 'local_pickup' ) !== false) {

        // Set variable
        $new_subtotal = 0;
        
        // Set discount excluded categories list
        $arr_discount_excluded_category = ['Category 1', 'Test Category'];

        // Set variable for matched excluded category from the cart list
        $arr_discount_excluded_category_matched = [];

        // Loop though each cart items and set prices in an array
        foreach ( $cart->get_cart() as $cart_item ) {

            // Get product
            $product = wc_get_product( $cart_item['product_id'] );

            // Get product category
            $category_list = wp_get_post_terms($cart_item['product_id'],'product_cat',array('fields'=>'names'));
            
            // Product has no discount
            $arr_discount_excluded_category_matched_by_item = array_intersect($category_list, $arr_discount_excluded_category);
            if ( ! $product->is_on_sale() && empty($arr_discount_excluded_category_matched_by_item)) {
                // line_subtotal
                $line_subtotal = $cart_item['line_subtotal'];

                // Add to new subtotal
                $new_subtotal += $line_subtotal;
            }
            else{
                $arr_discount_excluded_category_matched = array_merge($arr_discount_excluded_category_matched, $arr_discount_excluded_category_matched_by_item);
            }
        }
        
        // Calculate the discount
        $discount = 0;
        if($new_subtotal > 0){
            $discount = $new_subtotal * $percentage / 100;
        }
        
        //Add notification
        if(!empty($arr_discount_excluded_category_matched)){
            $str_message = 'Pickup discount does not apply to products from the Category "' . implode('", "', array_unique($arr_discount_excluded_category_matched)) . '"';
            wc_add_notice($str_message, 'notice');
        }

        // Add the discount
        $cart->add_fee( __('Discount') . ' (' . $percentage . '%)', -$discount );
    }
}

Based my update discount will not apply Category 1, Test Category when shipping method is local_pickup and if any of those category products found from the cart list, it will show notification to customer on the success page.

Thank you.

Everything works just fine! Many thanks! Only there is a question. As I understand it, I can specify any number of categories here? — Dmitry, Feb 02 '21 at 18:15
You can list down all the excluded categories in variable $arr_discount_excluded_category as an array — Karthik Sekar, Feb 02 '21 at 18:30

As i can see your code, you have already used below function to get all product added in cart

/* Get product */ $product = wc_get_product( $cart_item['product_id'] );

now you just need to check that your product belongs to any of that category you want to check

i think this way you can figure out
