从 WooCommerce 中的变体产品获取自定义字段值和最高价格

Question

我正在尝试显示来自 XX 的变体自定义价格跨度。

• 最低价格来自（多个）自定义字段值，我需要使用最低值。

• 最高价格应该是变化最高价格。

如果变体具有bulk_price价值，我只想要这个，并且只在档案页面中显示它。我需要获取自定义字段值和最高价格。

这就是我所拥有的：

function change_product_price_display( $price) {

    $bulk_price = get_post_meta([ 'variation_id' ], 'bulk_price', true);

    $priceMax        = $product->get_variation_price('max'); // Max price

    //only show in archives 

    if (is_product_category()) {

        //only if there is a bulk price

        if ( $bulk_price ) {

            return ' <span class="price-suffix">' . ' From ' . get_woocommerce_currency_symbol() .__( $bulk_price , "woocommerce") . ' - ' . $priceMax   . '</span>';   

        }

    }

    //don't affect other products

    else {

        return $price;

    }   

}

add_filter( 'woocommerce_get_price_html', 'change_product_price_display');

add_filter( 'woocommerce_cart_item_price', 'change_product_price_display');

Answer 1

在产品类别存档中显示最低值（自定义字段）到最高价格。注释并在代码中添加解释// Display on product category archive lowest value to max pricefunction change_product_price_display( $price, $product ) {&nbsp; &nbsp; // Returns true when viewing a product category archive.&nbsp; &nbsp; if ( is_product_category() ) {&nbsp; &nbsp; &nbsp; &nbsp; // Set array&nbsp; &nbsp; &nbsp; &nbsp; $bulk_prices = array();&nbsp; &nbsp; &nbsp; &nbsp; // Loop for variations IDs&nbsp; &nbsp; &nbsp; &nbsp; foreach( $product->get_children() as $variation_id ) {&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; // Get post meta&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; $bulk_price = get_post_meta($variation_id, 'bulk_price', true);&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; // True&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; if( $bulk_price ) {&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; // Push&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; $bulk_prices[] = $bulk_price;&nbsp; &nbsp;&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; }&nbsp; &nbsp; &nbsp; &nbsp; }&nbsp; &nbsp; &nbsp; &nbsp; // NOT empty&nbsp; &nbsp; &nbsp; &nbsp; if( sizeof($bulk_prices) > 0 ) {&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; // Sort: low to high&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; sort($bulk_prices);&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; // First value&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; $lowest_value = reset( $bulk_prices );&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; // Get max price&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; $price_max = $product->get_variation_price('max');&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; // Output&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; $price = '<span class="price-suffix">From ' . get_woocommerce_currency_symbol() . $lowest_value . ' - ' . wc_price($price_max) . '</span>';&nbsp; &nbsp; &nbsp; &nbsp; }&nbsp; &nbsp; }&nbsp; &nbsp; return $price;}add_filter( 'woocommerce_variable_price_html', 'change_product_price_display', 10, 2 );为清楚起见，创建和保存自定义字段的代码// Add custom field input product variationsfunction action_woocommerce_variation_options_pricing( $loop, $variation_data, $variation ) {&nbsp;&nbsp;&nbsp; &nbsp; woocommerce_wp_text_input( array(&nbsp; &nbsp; &nbsp; &nbsp; 'id'&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; => 'bulk_price[' . $loop .
