在 WooCommerce 单品页面显示总价，产品原价 *​​ 最小数量

Question

我想创建一个 PHP 代码片段，在 WooCommerce 单品页面上显示总价，原始产品价格 * 最小数量

根据 WooCommerce - auto update total price when quantity changed 答案代码，这是我目前所拥有的：

add_action( 'woocommerce_single_product_summary', 'woocommerce_total_product_price', 31 );
function woocommerce_total_product_price() {
    global $woocommerce, $product; 
    // let's setup our divs 
    echo sprintf('<div id="product_total_price" style="margin-bottom:20px;">%s %s</div>',__('Prezzo Totale:','woocommerce'),'<span class="price">'.$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
}

问题是查看单品页面时显示的是一件商品数量的价格。更改事件在数量更改时发生，因此在此事件发生之前不执行任何计算。

我有一个B2B网站，所以当客户查看单个产品页面时，他们会立即看到最小数量，那么我如何才能立即获得每个产品的最小数量的总价？

Answer 1

以下代码在加载页面时考虑了产品数量，然后在更改产品数量时更新价格。

通过代码中添加的注释标签进行解释

function action_woocommerce_single_product_summary() {
    global $product;
    
    // Getters
    $price = $product->get_price();
    $currency_symbol = get_woocommerce_currency_symbol();
    
    // let's setup our div
    echo sprintf('<div id="product_total_price" style="margin-bottom:20px;">%s %s</div>', __('Product Total:','woocommerce'), '<span class="price">' . $currency_symbol . $price . '</span>' );
    ?>
    <script>
    jQuery(function($) {
        // jQuery variables
        var price = <?php echo $price; ?>, 
            currency = '<?php echo $currency_symbol; ?>',
            quantity =  $( '[name=quantity]' ).val();
            
        // Code to run when the document is ready
        var product_total = parseFloat( price * quantity );
        $( '#product_total_price .price' ).html( currency + product_total.toFixed( 2 ) );
            
        // On change
        $( '[name=quantity]' ).change( function() {
            if ( ! ( this.value < 1 ) ) {
                product_total = parseFloat( price * this.value );

                $( '#product_total_price .price' ).html( currency + product_total.toFixed( 2 ) );
            }
        });
    });
    </script>
    <?php

}
// We are going to hook this on priority 31, so that it would display below add to cart button.
add_action( 'woocommerce_single_product_summary', 'action_woocommerce_single_product_summary', 31, 0 );

Answer 2

$product->get_price() 将 return 1 件产品的价格。

第一次可以用get_min_purchase_quantity()乘以价格。

add_action( 'woocommerce_single_product_summary', 'woocommerce_total_product_price', 31 );
function woocommerce_total_product_price() {
    global $woocommerce, $product; 
    // let's setup our divs 
$price = $product->get_price();
$min_qnty = $product->get_min_purchase_quantity();
$initial_price = floatval($price) * intval ($min_qnty);
    echo sprintf('<div id="product_total_price" style="margin-bottom:20px;">%s %s</div>',__('Prezzo Totale:','woocommerce'),'<span class="price">'.$initial_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
}

Answer 3

我遇到了类似的问题，并在周围找到了很多答案，但是我根据之前的答案和在线资源编写的这个是唯一一个在最小数量和页面重新加载问题上没有显示正确总价的情况下完美运行的问题

// Priority 31 is placed below the 'add to cart' button
add_action( 'woocommerce_single_product_summary', 'action_woocommerce_single_product_summary', 31, 0 );

function action_woocommerce_single_product_summary() {
    global $product;
    
    $price = $product->get_price();
    $currency_symbol = get_woocommerce_currency_symbol();
    $min_qnty = $product->get_min_purchase_quantity();
    $initial_price = floatval($price) * intval ($min_qnty);
    
    // leave the span class 'prezzo' as it is or it won't render the price
    echo sprintf('<div id="product_total_price">%s %s</div>', __('Total:','woocommerce'), '<span class="prezzo">' . $currency_symbol . $initial_price . '</span>' );
    ?>
    <script>
    jQuery(function($) {
        // vars
        var price = <?php echo $price; ?>, 
            currency = '<?php echo $currency_symbol; ?>',
            quantity =  $( '[name=quantity]' ).val();
            
        var product_total = parseFloat( price * quantity );
        $( '#product_total_price .prezzo' ).html( currency + product_total.toFixed( 2 ) );
            
        // On change
        $( '[name=quantity]' ).change( function() {
            if ( ! ( this.value < 1 ) ) {
                product_total = parseFloat( price * this.value );

                $( '#product_total_price .prezzo' ).html( currency + product_total.toFixed( 2 ) );
            }
        });
    });
    </script>
    <?php
}
