I like the fact that it's possible to do. I am wondering if anyone has a step-by-step guide on making this happen? I have wooCommerce (just installed), and need to move this metadata to its own custom table.
Any help (write-up / instructions / guide) would be welcomed.
And you can also save any post meta to the custom table but WooCommerce or other plugins have its own procedure to save its own meta to the database. For example, WooCommerce saves the product meta SKU, Price, Stock Quantity ... to the table wc_product_meta_lookup
So if you want to save this meta of Product, you should create action and fire when WooCommerce saves the meta and save it to the custom table.
