[英]Add sale price programmatically to product variations
I need to update the sale price programmatically, on variable product and all his variations.我需要以编程方式更新可变产品及其所有变体的销售价格。
What kind of meta field do I need to add?我需要添加什么样的元字段?
I'm trying to update main product such as:我正在尝试更新主要产品,例如:
update_post_meta($post_id, '_regular_price', '100');
update_post_meta($post_id, '_price', '50');
update_post_meta($post_id, '_sale_price', '50');
and then I update every single variations然后我更新每一个变化
update_post_meta($variation_id, '_regular_price', '100');
update_post_meta($variation_id, '_price', '50');
update_post_meta($variation_id, '_sale_price', '50');
update_post_meta($variation_id, 'attribute_pa_taglia', $term_slug);
update_post_meta($variation_id, '_stock', $stock);
update_post_meta($variation_id, '_stock_status', 'instock');
update_post_meta($variation_id, '_manage_stock', 'yes');
Back end: product detail, everything ok后端:产品细节,一切正常
However backend (product list) and frontend get me old price但是后端(产品列表)和前端给我旧的价格
Furthermore, I've find other solution that work same:此外,我找到了其他工作相同的解决方案:
$product_variable = new WC_Product_Variable($post_id);
$product_variable->sync($post_id);
wc_delete_product_transients($post_id);
Update: Prices are also cached in transient
wp_options
table.更新:价格也缓存在临时
wp_options
表中。Let say your product ID is
222
, you will have that transients meta_keys inwp_options
table (for this product ID):假设您的产品 ID 是
222
,您将在wp_options
表中拥有该瞬态 meta_keys(对于此产品 ID):'_transient_timeout_wc_product_children_22' '_transient_wc_product_children_22' '_transient_timeout_wc_var_prices_222' // <=== <=== HERE '_transient_wc_var_prices_222' // <=== <=== <=== HERE
What you can try to do is to update expiration date
meta_value
to an outdated timestamp, this way:您可以尝试做的是将过期日期
meta_value
更新为过时的时间戳,如下所示:// Set here your product ID $main_product_id = 222 $transcient_product_meta_key = '_transient_wc_var_prices_'. $main_product_id; update_option( $transcient_product_meta_key, strtotime("-12 hours") ); wp_cache_delete ( 'alloptions', 'options' ); // Refresh caches
This way you will force the system to rebuild this outdated cached transient.
通过这种方式,您将强制系统重建这个过时的缓存瞬态。
Additionally you should try to add/update in your parent product ID (the main product where variation are set) these:此外,您应该尝试在您的父产品 ID(设置变体的主要产品)中添加/更新这些:
// Set here your Main product ID (for example the last variation ID of your product)
$post_id = 22;
// Set here your variation ID (for example the last variation ID of your product)
$variation_id = 24;
// Here your Regular price
$reg_price = 100;
// Here your Sale price
$sale_price = 50;
update_post_meta($post_id, '_min_variation_price', $sale_price);
update_post_meta($post_id, '_max_variation_price', $sale_price);
update_post_meta($post_id, '_min_variation_regular_price', $reg_price);
update_post_meta($post_id, '_max_variation_regular_price', $reg_price);
update_post_meta($post_id, '_min_variation_sale_price', $sale_price);
update_post_meta($post_id, '_max_variation_sale_price', $sale_price);
update_post_meta($post_id, '_min_price_variation_id', $variation_id);
update_post_meta($post_id, '_max_price_variation_id', $variation_id);
update_post_meta($post_id, '_min_regular_price_variation_id', $variation_id);
update_post_meta($post_id, '_max_regular_price_variation_id', $variation_id);
update_post_meta($post_id, '_min_sale_price_variation_id', $variation_id);
update_post_meta($post_id, '_max_sale_price_variation_id', $variation_id);
// Optionally
wc_delete_product_transients($variation_id);
For April 2021, this is the code:对于 2021 年 4 月,这是代码:
$variation = wc_get_product_object( 'variation', $variation_id );
$variation->set_props(
array(
'regular_price' => $price,
'sale_price' => $sale_price,
)
);
$variation->save();
