WooCommerce: Create Product Programmatically

No matter if this snippet suits your needs or not, it’s still interesting to see how you can create a brand new WooCommerce product programmatically / automatically when a certain even triggers.

In this case studio, we’ll see how to generate a brand new product, set its featured image, price, category, title and a download file as soon as an image is uploaded in the WordPress backend Media section. This would be super useful for photographers for example – simply upload a new image to the WordPress Media Library, and a new product is automatically created.

Of course, you can customize the code and use it with different triggers. For example, you may need to create a new product automatically when each phone product needs always a matching case product, just with a different title. Or maybe you want to tie product creation once an order is placed.

Either way, enjoy!

This product was created automatically, after uploading Calm.jpg to the WordPress Media Library. You find more screenshots below.

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

  2. I couldn’t get this to work. I admit I loathe WP and find it completely dyslexic – so I may be biased. But no – unfortunately spent the whole day on this and nothing worked. 9/7/22

  3. Hi, thanks for your post.

    Is there any way to add brand name to a product?

    thanks again

    1. Hi Javier thanks so much for your comment! Yes, this is definitely possible, but I’m afraid it’s custom work. If you’d like to get a quote, feel free to contact me here. Thanks a lot for your understanding!
