The default WooCommerce Dashboard Products page (/wp-admin/edit.php?post_type=product page) shows the list of products in a table. Default fields are: Image, SKU, Stock, Price, Categories, Tags, Featured and Date.
Sometimes, these columns are not enough and you need more. For example, you might want to quickly take a look at a product custom field, such as “visibility” (whether the product is hidden or not).
So, here’s the snippet for that. Of course, you can adapt it to show your own custom field, an ACF field or whatever product-related information you require.
While working on a workaround for a client, I had to hide a hidden product from the cart, checkout, order received and emails. Hidden products already don’t show on the shop and category pages, but they do show on the cart if they’re added to cart “programmatically”.
