在Woocommerce可变产品上的变体描述之前进行自定义显示

Question

我需要在wooccommerce中的变体产品的描述之前添加我自己的价格表。我通过自定义class-wc-product-variable.php的get_available_variation函数来实现这一点，该函数位于wooccommerce的includes目录中。

我不想覆盖这个插件，因为更新后更改会丢失。

如何在不攻击wooccommerce的情况下修改此功能？

public function get_available_variation( $variation ) {
if ( is_numeric( $variation ) ) {
$variation = wc_get_product( $variation );
}
if ( ! $variation instanceof WC_Product_Variation ) {
return false;
}
// See if prices should be shown for each variation after selection.
$show_variation_price = apply_filters( 'woocommerce_show_variation_price', $variation->get_price() === '' || $this->get_variation_sale_price( 'min' ) !== $this->get_variation_sale_price( 'max' ) || $this->get_variation_regular_price( 'min' ) !== $this->get_variation_regular_price( 'max' ), $this, $variation );
return apply_filters(
'woocommerce_available_variation', array(
'attributes'            => $variation->get_variation_attributes(),
'availability_html'     => wc_get_stock_html( $variation ),
'backorders_allowed'    => $variation->backorders_allowed(),
'dimensions'            => $variation->get_dimensions( false ),
'dimensions_html'       => wc_format_dimensions( $variation->get_dimensions( false ) ),
'display_price'         => wc_get_price_to_display( $variation ),
'display_regular_price' => wc_get_price_to_display( $variation, array( 'price' => $variation->get_regular_price() ) ),
'image'                 => wc_get_product_attachment_props( $variation->get_image_id() ),
'image_id'              => $variation->get_image_id(),
'is_downloadable'       => $variation->is_downloadable(),
'is_in_stock'           => $variation->is_in_stock(),
'is_purchasable'        => $variation->is_purchasable(),
'is_sold_individually'  => $variation->is_sold_individually() ? 'yes' : 'no',
'is_virtual'            => $variation->is_virtual(),
'max_qty'               => 0 < $variation->get_max_purchase_quantity() ? $variation->get_max_purchase_quantity() : '',
'min_qty'               => $variation->get_min_purchase_quantity(),
'price_html'            => $show_variation_price ? '<span class="price">' . $variation->get_price_html() . '</span>' : '',
'sku'                   => $variation->get_sku(),
'variation_description' => CUSTOM_PRICE_TABLE($variation) . wc_format_content( $variation->get_description() ),
'variation_id'          => $variation->get_id(),
'variation_is_active'   => $variation->variation_is_active(),
'variation_is_visible'  => $variation->variation_is_visible(),
'weight'                => $variation->get_weight(),
'weight_html'           => wc_format_weight( $variation->get_weight() ),
), $this, $variation
);
}

我所要做的唯一更改是在变体描述中添加"CUSTOM_PRICE_TABLE($Variation("。

您只需要这样使用woommerce_available_variation过滤器挂钩：

add_filter( 'woocommerce_available_variation', 'form_to_out_of_stock_product_variations', 10, 3 );
function form_to_out_of_stock_product_variations( $data, $product, $variation ) {
if( CUSTOM_PRICE_TABLE($variation) )
$data['variation_description'] = CUSTOM_PRICE_TABLE($variation) . $data['variation_description'],
return $data;
}

代码位于活动子主题(或活动主题(的function.php文件中。它应该有效。
