How to implement scheduled price updates?

Question

WordPress

There is a site with goods, implemented on wp + woocommerce.

Products are imported every night (updating balances, adding new products via wp all import) using the supplier's link.

The price field indicates the wholesale price. But I want to massively change prices, by ranges, if the product is from 100 to 500 rubles, then the markup is 20% ... and so on, in principle, I found a plugin that changes massively, but the problem is that the plugin has set new prices, but at night the import took place and the prices were updated (overwritten).

What are the ways to solve this problem, so that the margin on the goods is set according to the schedule after each import?

Answer 1

1. We get all the goods get_posts( [ 'post_type' => 'product' ] );
2. In the loop we get the required field using get_post_meta()
3. We do something with it
4. Push back update_post_meta()
5. We hang everything on the crowns and test
