这段代码有什么问题?我对这段代码有一些问题。
function my_woocommerce_get_price($price, $_product) {
$kurs = 1.67;
$new_price = $price / $kurs;
$product_categories = array('laminat');
if( has_term( $product_categories, 'product_cat', $product->get_id() ) ) {
return $new_price; // новая цена
} else {
return $price;
}
}
add_filter('woocommerce_get_price', 'my_woocommerce_get_price', 100, 2);
当我尝试保存代码时遇到此错误。

您的代码中有多个错误,自 WooCommerce 3 起,钩子
woocommerce_get_price
已过时、已弃用并替换为:
woocommerce_product_get_price
适用于 product
帖子类型woocommerce_product_variation_get_price
适用于 product_variation
帖子类型基于 通过 WooCommerce 3+ 中的挂钩更改产品价格,以下是更改特定产品类别的产品价格的方法(需要更多代码):
// Simple, grouped and external products (and product variations)
add_filter( 'woocommerce_product_get_price', 'custom_product_price', 100, 2 );
add_filter( 'woocommerce_product_get_regular_price', 'custom_product_price', 100, 2 );
add_filter( 'woocommerce_product_variation_get_price', 'custom_product_price', 100, 2 );
add_filter( 'woocommerce_product_variation_get_regular_price', 'custom_product_price', 100, 2 );
function custom_product_price( $price, $product ) {
$category_terms = array('laminat');
// Get the parent variable product for product variations
$product_id = $product->get_parent_id() ? $product->get_parent_id() : $product->get_id();
if( has_term( $category_terms, 'product_cat', $product_id ) ) {
$price *= 1.67; // новая цена
}
return $price;
}
// Variable products (price range)
add_filter('woocommerce_variation_prices_price', 'custom_variable_price_range', 100, 3 );
add_filter('woocommerce_variation_prices_regular_price', 'custom_variable_price_range', 100, 3 );
function custom_variable_price_range( $price, $variation, $product ) {
$category_terms = array('laminat');
if( has_term( $category_terms, 'product_cat', $product->get_id() ) ) {
$price *= 1.67; // новая цена
}
return $price;
}
// Handling price caching, for better performances
add_filter( 'woocommerce_get_variation_prices_hash', 'custom_variable_product_prices_hash', 100, 3 );
function custom_variable_product_prices_hash( $price_hash, $product, $for_display ) {

$price_hash[] = '1.67';
}
return $price_hash;
}
