WooCommerce: Get Product IDs (All, by Tag, by Category)

When you work with WooCommerce PHP snippets, you often need to “get” stuff off your WordPress database in order to make some calculations and return the result on the screen. And if there is something I often google is “How do I get all my store’s product IDs?“.

Thankfully the wc_get_products WooCommerce function gives us the answer. Enjoy 🙂

Where to add custom code?

You should place custom PHP in functions.php and custom CSS in style.css of your child theme: where to place WooCommerce customization?

This code still works, unless you report otherwise. To exclude conflicts, temporarily switch to the Storefront theme, disable all plugins except WooCommerce, and test the snippet again: WooCommerce troubleshooting 101
