Tambahkan biaya tambahan untuk pengiriman flat rate setiap 2 item dari kategori tertentu di WooCommerce

Question

Berdasarkan Tambahkan biaya tambahan untuk pengiriman tarif tetap setiap 3 item dalam kode jawaban Woocommerce , saya telah membuat beberapa perubahan untuk menambahkan biaya tambahan ke metode pengiriman rata-rata masing-masing 2 item (bukan masing-masing 3 item) dan hanya jika ada item eksklusif dari kategori tertentu (di sini kategori "Kaos").

Ini percobaan kode saya:

// add X amount to shipping for every 2 items added to the cart (flat rate only)
add_filter('woocommerce_package_rates', 'shipping_additional_cost_each_three_items', 100, 2);
function shipping_additional_cost_each_three_items( $rates, $package ){
    if ( is_admin() && ! defined( 'DOING_AJAX' ) )
        return $rates; // HERE set your additional shipping cost $additional_cost = 8.40;
    $items_count = WC()->cart->get_cart_contents_count(); // Define/replace here your correct category slug (!) $product_category = 't-shirts';
    $prod_cat = false; // Going through each item in cart to see if there is anyone of your category foreach ( WC()->cart->get_cart() as $cart_item ) {
        $product_id = $cart_item['product_id'];
        if ( has_term( $product_category, 'product_cat', $product_id ) ){
            $prod_cat = true; } } // Loop through the shipping taxes array foreach ( $rates as $rate_key => $rate ){
        $has_taxes = false; // Targetting "flat rate" if( 'flat_rate' === $rate->method_id ){

            // Get the initial cost
            $initial_cost = $new_cost = $rates[$rate_key]->cost;

            // Adding the additional cost if product in T-Shirt category after every 2 items (3, 6, 9 …)
            if ( $prod_cat ) { for($i = 0; $i <= $items_count; $i+=3){ $new_cost += $additional_cost; } } // Set the new cost $rates[$rate_key]->cost = $new_cost;

            // Taxes rate cost (if enabled)
            $taxes = []; // Loop through the shipping taxes array (as they can be many) foreach ($rates[$rate_key]->taxes as $key => $tax){ if( $rates[$rate_key]->taxes[$key] > 0 ){
                    // Get the initial tax cost
                    $initial_tax_cost = $new_tax_cost = $rates[$rate_key]->taxes[$key]; // Get the tax rate conversion $tax_rate    = $initial_tax_cost / $initial_cost;

                    // Set the new tax cost
                    $taxes[$key] = $new_cost * $tax_rate;
                    $has_taxes = true; // Enabling tax } } } if( $has_taxes )
            $rates[$rate_key]->taxes = $taxes; return $rates;
    }
}

Untuk metode pengiriman yang dipilih "Tarif tetap", kode berfungsi dengan baik saat item dari kategori "kaos" ada di keranjang. Namun jika ada item yang tidak termasuk dalam kategori "kaos", harga tersebut akan hilang begitu saja dan judulnya tidak menunjukkan jumlahnya.

Dapatkah seseorang memberi tahu saya di mana saya harus menempatkan kondisi 'jika kategori adalah X', untuk membuat kode itu berfungsi?

Ada beberapa kesalahan dalam kode Anda (seperti return $rates;itu harus terjadi tepat sebelum tanda kurung tutup terakhir). Coba kode revisited berikut sebagai gantinya:

add_filter('woocommerce_package_rates', 'shipping_additional_cost_each_three_items', 100, 2);
function shipping_additional_cost_each_three_items( $rates, $package ){ if ( is_admin() && ! defined( 'DOING_AJAX' ) ) return $rates;

    // HERE set your additional shipping cost
    $additional_cost = 8.40; $each_items      = 2; // Number of items (for additional cost)

    // Her set your category(ies) (can be term Ids slugs or names)
    $product_categories = array('t-shirts'); $items_cat_count    = 0; // Initializing

    // Loop through cart items for the current shipping package        
    foreach( $package['contents'] as $cart_item ) {
        if ( ! has_term( $product_categories, 'product_cat', $cart_item['product_id'] ) ){
            $items_cat_count += $cart_item['quantity']; // Count items from defined category
        }
    }
    
    if ( $items_cat_count >= $each_items ) {
       // Loop through the shipping taxes array
        foreach ( $rates as $rate_key => $rate ){ // Targetting "flat rate" if( 'flat_rate' === $rate->method_id ){
                $initial_cost = $new_cost = $rate->cost; // Get the initial cost $has_taxes    = false; // Initializing
                $taxes = array(); // Initializing // Adding to cost the additional cost each 2 items (2, 4, 6 …) for($i = 0; $i <= $items_cat_count; $i += $each_items){
                    $new_cost += $additional_cost;
                }
                $rates[$rate_key]->cost = $new_cost; // Set the new cost // Taxes rate cost (if any) - Loop through taxes array (as they can be many) foreach ($rate->taxes as $key => $tax){
                    if( $tax > 0 ){ // Get the initial tax cost $initial_tax_cost = $new_tax_cost = $tax;
    
                        // Get the tax rate conversion
                        $tax_rate = $initial_tax_cost / $initial_cost; // Set the new tax cost in the array $taxes[$key] = $new_cost * $tax_rate; $has_taxes   = true; // Enabling tax changes
                    }
                }
                // set array of shipping tax cost
                if( $has_taxes ) { $rates[$rate_key]->taxes = $taxes; 
                }
            } 
        }
    }
    return $rates;
}

Kode masuk ke file functions.php dari tema anak aktif (atau tema aktif). Ini harus berhasil.

Jangan lupa untuk mengosongkan keranjang Anda untuk menyegarkan data pengiriman yang disimpan dalam cache.
