Question

我需要这个功能，我发现它可以正确使用单个产品，但是，我无法让它在变量产品中运行。

这是

中单品的代码

的functions.php ：

add_action( 'woocommerce_single_product_summary', 
'woocommerce_total_product_price', 31 );
function woocommerce_total_product_price() {
global $woocommerce, $product;
// let's setup our divs
echo sprintf('<div id="product_total_price" style="margin-bottom:20px;">%s 
%s</div>',__('Total Words Number:','woocommerce'),'<span 
class="price">'.$product->get_price().'</span>');
?>
    <script>
        jQuery(function($){
            var price = <?php echo $product->get_price(); ?>,
                currency = '<?php echo get_woocommerce_currency_symbol(); ?
 >';

            $('[name=quantity]').change(function(){
                if (!(this.value < 1)) {

                    var product_total = parseFloat(price * this.value);

                    $('#product_total_price .price').html( currency + 
 product_total.toFixed(2));

                }
            });
        });
    </script>
<?php
}

我真的很感谢你的帮助！

Answer 1

解决了，也适用于可变产品。

Answer 2

以上代码不适用于可变产品。仅适用于简单产品

    add_action( 'woocommerce_single_product_summary', 
'woocommerce_total_product_price', 31 );
function woocommerce_total_product_price() {
global $woocommerce, $product;
// let's setup our divs
echo sprintf('<div id="product_total_price" style="margin-bottom:20px;">%s 
%s</div>',__('Total Words Number:','woocommerce'),'<span 
class="price">'.$product->get_price().'</span>');
?>
    <script>
        jQuery(function($){
            var price = <?php echo $product->get_price(); ?>,
                currency = '<?php echo get_woocommerce_currency_symbol(); ?
 >';

            $('[name=quantity]').change(function(){
                if (!(this.value < 1)) {

                    var product_total = parseFloat(price * this.value);

                    $('#product_total_price .price').html( currency + 
 product_total.toFixed(2));

                }
            });
        });
    </script>
<?php
}

我不知道它是如何工作的，但它有效

// shows the total price and total weight based on the quantity entered
add_action( 'woocommerce_single_product_summary', 'show_total_price_and_total_weight_by_quantity', 31 );
function show_total_price_and_total_weight_by_quantity() {
    // create the divs that will contain the total price and total weight
    echo sprintf('<div id="product_total_price" style="display:none;margin-bottom:20px;">%s %s</div>', __('Totale Prodotto:','woocommerce'),'<span class="price"></span>');
    echo sprintf('<div id="product_total_weight" style="display:none;margin-bottom:20px;">%s %s</div>', __('Totale Peso:','woocommerce'),'<span class="weight"></span>');
}

// change the total price and total weight based on the quantity entered
add_action( 'wp_footer', 'change_total_price_and_total_weight_by_quantity', 99 );
function change_total_price_and_total_weight_by_quantity() {
    // only on the product page
    if ( ! is_product() ) {
        return;
    }

    global $product;
    
    // initializes the array that will contain the product data
    $product_data = array();

    // do divs need to be shown?
    $show = true;

    // gets the currency and unit of weight
    $currency = get_woocommerce_currency_symbol();
    $weight_unit = get_option('woocommerce_weight_unit');

    // if the product is simple
    if ( $product->is_type( 'simple' ) ) {
        // set the type of product
        $product_data['type']  = 'simple';
        // get simple product data
        $product_data['price'] = $product->get_price();
        $product_data['currency'] = $currency;
        $product_data['weight'] = $product->get_weight();
        $product_data['weight_unit'] = $weight_unit;
    }

    // if the product is variable
    if ( $product->is_type( 'variable' ) ) {

        $variation_ids = $product->get_children();

            $variation = wc_get_product( $variation_id );
            // gets product variation data
            $product_data['variation'][$variation_id]['price'] = $variation->get_price();
            $product_data['variation'][$variation_id]['currency'] = $currency;
            $product_data['variation'][$variation_id]['weight'] = $variation->get_weight();
            $product_data['variation'][$variation_id]['weight_unit'] = $weight_unit;
        }
        // hides the div
        $show = false;
    }

    // returns the JSON representation of a data
    $product_data_json = json_encode( $product_data );
