我正在使用 woocommerce 我刚刚使用钩子编写了一个函数，因为我需要使用公式计算每种产品的价格所以我所做的只是复制修改它的原始函数并将其添加到我的 function.php 中，我看到它正在工作在我的本地机器上很好，但在我的服务器上不行。在服务器中，它不保存变化。
在这里，我添加了我在 finctions.php 中添加的代码
remove_action('woocommerce_product_write_panels', 'variable_product_type_options');
add_action( 'woocommerce_product_write_panels','variable_product_type_options_with_goldprice_calculation' );
function variable_product_type_options_with_goldprice_calculation(){
global $post, $woocommerce;
$attributes = maybe_unserialize( get_post_meta( $post->ID, '_product_attributes', true ) );
// See if any are set
$variation_attribute_found = false;
if ( $attributes ) foreach( $attributes as $attribute ) {
if ( isset( $attribute['is_variation'] ) ) {
$variation_attribute_found = true;
break;
}
