Whenever we need to do custom WooCommerce work, remembering how to get “things” is the most time-consuming task. So, a Google search often helps us find the right and quickest solution.
For example, it’s easy to “get the current product’s categories“, but how can we get the “parent product categories” only? In today’s snippet we will see how this can be achieved in 7 lines of PHP. Enjoy!
PHP Snippet: Get Current Product’s Parent Categories @ Single Product Page
The PHP below fills the $parent_categories array with parent product category IDs.
You can place PHP snippets at the bottom of your child theme functions.php file (delete "?>" if you have it there). CSS, on the other hand, goes in your child theme style.css file. Make sure you know what you are doing when editing such files - if you need more guidance, please take a look at my free video tutorial "Where to Place WooCommerce Customization?"
Does this snippet (still) work?
Please let me know in the comments if everything worked as expected. I would be happy to revise the snippet if you report otherwise (please provide screenshots). I have tested this code with Storefront theme, the WooCommerce version listed above and a WordPress-friendly hosting on PHP 7.3.
