将折扣百分比添加到销售的可变产品中 [英] Adding the discount percentage to variable products on sale

问题描述

我正在尝试在使用 WooCommerce 的网站中添加折扣百分比价格.

I’m trying to add a discount percentage aside price in a site that uses WooCommerce.

我已将此脚本应用于标准价格和销售价格:

I’ve applied this script for the standard price and the sale price:

// Add save percentage next to sale item prices.
add_filter( 'woocommerce_get_price_html', 'adventure_tours_sales_price', 10, 2 );
function adventure_tours_sales_price( $price, $product ){
  $percentage = round( ( ( $product->regular_price - $product->sale_price ) / $product->regular_price ) * 100 );
  return $price . sprintf( __(' Save %s', 'woocommerce' ), $percentage . '%' );
}

上面的脚本有效.

在前端，我有价格百分比.

In front-end, I have the price percentage.

现在我想对产品变化价格应用相同的脚本.

Now I want apply the same script to the product variation price.

我检查了产品变体选项并尝试了以下操作:

I’ve checked the product variation option and tried something like this:

// Add save percentage next to sale item prices.
add_filter( 'woocommerce_get_price_html', 'adventure_tours_sales_price', 10, 2 );
function adventure_tours_sales_price( $price, $product ){
  if( $product->is_type( 'variable' ) ) {
    $percentage = round( ( ( $product->regular_price - $product->sale_price ) / $product->regular_price ) * 100 );
    return $price . sprintf( __(' Save %s', 'woocommerce' ), $percentage . '%' );
  }else{
    $percentage = round( ( ( $product->regular_price - $product->sale_price ) / $product->regular_price ) * 100 );
    return $price . sprintf( __(' Save %s', 'woocommerce' ), $percentage . '%' );
  }
}

但它不起作用，百分比不适用于价格.

But it does not work, the percentage is not applied to the price.

前端也不行.

可变产品更复杂，因为您有 2 个不同的价格位置，第一个显示最小和最大价格(当您有多个变体时)，第二个显示所选变体的价格.我对你的原始代码做了很多更改.

For variable products is more complicated as you have 2 different locations with prices, the first one displays the minimal and maximal price (when you have multiple variations) and the second one displays the price from the selected variations. I have changed a lot your original code.

这是显示折扣百分比周围的自定义动态标签的正确代码:

Here the correct code to display that custom dynamic labels arround discounted percentages:

add_filter('woocommerce_variable_get_price_html','adventure_tours_sales_price', 10, 2 );
add_filter('woocommerce_get_price_html','adventure_tours_sales_price', 10, 2 );
function adventure_tours_sales_price( $price, $product ){

    // Variables initialisation
    $regular_price = $product->get_regular_price();
    $sale_price    = $product->get_sale_price();
    $save_text     = __('Save', 'woocommerce') . ' ';

    if(!empty($sale_price)) {
        // Percentage calculation
        $percentage = '<span class="save-percent"> ' .$save_text . round( ( ( $regular_price -  $sale_price ) / $regular_price ) * 100 ) . '%</span>';

        $price = '<del class="strike">' . wc_price( $regular_price ) . '</del>
        <ins class="highlight">' . wc_price( $sale_price )  . $percentage . '</ins>';
    } else {
        $price = '<ins class="highlight">'.wc_price( $regular_price ).'</ins>';
    }
    return $price;
}

add_filter('woocommerce_variable_get_price_html', 'adventure_tours_sales_min_max_prices', 20, 2);
function adventure_tours_sales_min_max_prices( $price, $product) {

    // Variables initialisation
    $variation_min_reg_price = $product->get_variation_regular_price('min', true);
    $variation_max_reg_price = $product->get_variation_regular_price('max', true);
    $variation_min_sale_price = $product->get_variation_sale_price('min', true);
    $variation_max_sale_price = $product->get_variation_sale_price('max', true);
    $percentage_min = '';
    $percentage_max = '';
    $save_text     = __('Save', 'woocommerce') . ' ';

    // Percentage calculations
    if($variation_min_reg_price != $variation_min_sale_price)
        $percentage_min = '<span class="save-percent-min"> (' .$save_text . round( ( ( $variation_min_reg_price -  $variation_min_sale_price ) / $variation_min_reg_price ) * 100 ) . '%)</span>';
    if($variation_max_reg_price != $variation_max_sale_price)
        $percentage_max = '<span class="save-percent-max"> (' .$save_text . round( ( ( $variation_max_reg_price -  $variation_max_sale_price ) / $variation_max_reg_price ) * 100 ) . '%)</span>';

    if (($variation_min_reg_price != $variation_min_sale_price) || ($variation_max_reg_price != $variation_max_sale_price)) {
        $price = '<del class="strike">' . wc_price($variation_min_reg_price) . '-' . wc_price($variation_max_reg_price) .  '</del>
        <ins class="highlight">' . wc_price($variation_min_sale_price) . $percentage_min . ' - ' . wc_price($variation_max_sale_price) . $percentage_max . '</ins>';
    }
    return $price;
}

代码位于活动子主题(或主题)的functions.php 文件或任何插件文件中.
