How to update sale price woocommerce(3.0+) variable product?

Replies: 0

I am using WordPress 4.7.4 and woocommerce 3.0.5.

I updated _sale_price, _price, _regular_price using meta_id with below code

` $meta_tbl = $wpdb->prefix.’postmeta’;
foreach ($_POST[‘loop’] as $loop_k => $loop_v) {
$wpdb->update(
$meta_tbl,
array( ‘meta_value’ => $loop_v[‘price’] ),
array( ‘meta_id’ => $loop_v[‘price_meta_id’] ),
array( ‘%d’ )
);
$wpdb->update(
$meta_tbl,
array( ‘meta_value’ => $loop_v[‘regular_price’] ),
array( ‘meta_id’ => $loop_v[‘regular_price_meta_id’] ),
array( ‘%d’ )
);
$wpdb->update(
$meta_tbl,
array( ‘meta_value’ => $loop_v[‘sale_price’] ),
array( ‘meta_id’ => $loop_v[‘sale_price_meta_id’] ),
array( ‘%d’ )
);
}`
but still shop page displaying old price of products, how it should be done properly ?
