Question

Iam trying to update woocommerce prices programmatically with with CRON.

I'm saving the new price to the _price, _regular_price and _sale_price post meta.

The post meta are correcty saved. But, somehow, the price is not updated.

This is a piece of the code:

function save_prices($post_ID){
    $woo_prod = wc_get_product( $post_ID );

    $price = some_function_to_get_the_price( $post_ID ); 


   if($woo_prod->is_type( 'simple' )){

        $woo_prod->update_meta_data( '_regular_price', $price );
        $woo_prod->update_meta_data( '_sale_price', $price );
        $woo_prod->update_meta_data( '_price', $price );

   }

   $woo_prod->save();
}

This function saves the post meta correctly, but woocommerce doesn't use these values for the product.

Anyone knows why this is happening?

Thanks

您应该使用Woocommerce 3中引入的新CRUD getters and setters methods：

function save_prices($post_ID){
    // Get an instance of the WC_Product object
    $product = wc_get_product( $post_ID );

    $price = some_function_to_get_the_price( $post_ID ); 

    if($product->is_type( 'simple' )){
        $product->set_regular_price($price);
        $product->set_sale_price($price);
        $product->set_price($price);
    }
    $product->save();
}

现在它应该工作并在前端显示更新的价格。
