我需要在woocommerce中描述变体产品之前添加自己的价格表。我是通过自定义woocommerce的include目录中的class-wc-product-variable.php的get_available_variation函数来实现的。
我不想覆盖此插件，因为更改将在更新后丢失。
如何修改此功能而不会破坏woocommerce？
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, $variation
);
}
我唯一要做的更改是在版本说明中添加“ CUSTOM_PRICE_TABLE（$变量）”。
您只需要以这种方式使用woocommerce_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;
}
代码进入您的活动子主题（或活动主题）的function.php文件中。它应该工作。
