Programming guide on adding per product shipping price

Hi esia168,

The shipping feature is, by far, the most complex piece of code of our plugin and cannot be captured into a single line of code but exists out of multiple funtions.

The code can be found in the /woo-product-feed-pro/classes/class-get-products.php file. The main function is woosea_get_shipping_cost();

Btw, you could checkout this shipping calculator plugin that display shipping info on product page https://codecanyon.net/item/woocommerce-shipping-calculator-on-product-page/11496815 , how they implement is quite simple but smart, basically what they did is add an item into the Woocommmerce (WC) cart programmatically, then use the existing WC code that is used in the checkout page to get the shipping information. So there’s no need to reinvent the wheel/functions on getting the shipping information. I have improvise their code to generate the string of shipping for multiple countries on a product. Wonder if you can follow some inspiration/solution from them. Here is roughly how

        public function googleShippingFeedStr(){
            $originalSetting = $_POST['calc_shipping_country'];
            $countries = ['US','CA', 'AU', 'GB', 'CH', 'SE', 'DK', 'FR', 'DE', 'AT', 'BE', 'IE', 'IL', 'IT', 'JP',
                'NL', 'NZ', 'NO', 'PL', 'PT', 'ZA', 'ES', 'TR', 'SG', 'MY', 'ID', 'AE', 'SA', 'KR', 'TH', 'VN', 'MX'];
            $shipCountryFeed = [];
            foreach($countries as $country){
                $_POST['calc_shipping_country'] = $country;

                WC_Shortcode_Cart::calculate_shipping();

                if (isset($_POST["product_id"]) && $this->check_product_incart($_POST["product_id"]) === false) {
                    $qty = (isset($_POST['current_qty']) && $_POST['current_qty'] > 0) ? $_POST['current_qty'] : 1;
                    if (isset($_POST['variation_id']) && $_POST['variation_id'] != "" && $_POST['variation_id'] > 0) {
                        $cart_item_key = WC()->cart->add_to_cart($_POST["product_id"], $qty, $_POST['variation_id']);
                    } else {
                        $cart_item_key = WC()->cart->add_to_cart($_POST["product_id"], $qty);
                    }

                    $packages = WC()->cart->get_shipping_packages();
                    $packages = WC()->shipping->calculate_shipping($packages);
                    $available_methods = WC()->shipping->get_packages();
                    WC()->cart->remove_cart_item($cart_item_key);
                } else {
                    $packages = WC()->cart->get_shipping_packages();
                    $packages = WC()->shipping->calculate_shipping($packages);
                    $available_methods = WC()->shipping->get_packages();
                }

                wc_clear_notices();
                if ($this->get_setting('shipping_type') == 2) {
                    if (isset($available_methods[0]["rates"]) && count($available_methods[0]["rates"]) > 0) {
                        $count = 0;
                        //echo '<ul class="shipping_with_price">';
                        foreach ($available_methods[0]["rates"] as $key => $method) {
                            $finalCost=$method->cost;
                            if(isset($method->taxes) && !empty($method->taxes)){
                                foreach($method->taxes as $tax){
                                    $finalCost=$finalCost+$tax;
                                }
                            }
                            //echo "<li>";
                            //echo wp_kses_post($method->label) . "&nbsp;<strong>(" . wc_price($finalCost) . ")</strong>";
                            //echo "</li>";
                            $pos = false;
                            $shipName = $method->label;
                            if( ($pos = stripos($shipName, '['))  !== FALSE )
                                $shipName = trim(substr($method->label, 0, $pos ));

                            $shipCountryFeed[] = $country.'::'.$shipName.':USD'.$finalCost;
                            break; //only the first default most important shipping
                        }
                        //echo '</ul>';
                    }
                }
            }

            //reset
            $_POST['calc_shipping_country'] = $originalSetting;
            WC_Shortcode_Cart::calculate_shipping();

            return join(',', $shipCountryFeed);

Thanks for the piece of code. Whenever we feel we need to re-do the shipping functionality as it got too complex we will look into this approach.

Best,
