WooCommerce: Do Something When Product is Published

A client needed to add “something” upon product publishing. For example, product meta key “total_sales” with value = 0 gets added automatically once a WooCommerce product is created.

So, how do we run (“hook”) our function when a new product is published?

WooCommerce: add_post_meta on product creation

PHP Snippet: Add Custom Meta When a Product is Published

In here we trigger our function when a product goes from a non-published status (‘draft’, ‘pending’, ‘private’, ‘future’) to ‘publish’ status.

add_action( 'transition_post_status', 'bbloomer_add_custom_meta_on_publish_product', 9999, 3 );

function bbloomer_add_custom_meta_on_publish_product( $new_status, $old_status, $post ) {
   if ( 'product' === $post->post_type && 'publish' === $new_status && 'publish' !== $old_status ) {
      update_post_meta( $post->ID, 'total_amount', '0' );
   }
}

Where to add this snippet?

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.

    I tried your code and i had a problem. It runs only when i go to products and click add new and as a result $post returns an object with empty properties. When i publish my product it doesn’t do anything. Am i doing something wrong?

    after publish, if we turn product published to draft for some time & publish again

    function re run.

    can we limit it to run once only.

    not everytime for same product that got published in past.

      Hi Arun 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!

    Good snippet, however you’ll probably want to add a quick check for the post type:

    if ($post->post_type != ‘product’) return;

    Otherwise you’ll end up adding extra meta data for all posts, including non-products.

    Hi Rodolfo,

    Is there any way to utilise this code snippet to notify authors when their products have been published? I am using woocommerce to sell books, and the books are uploaded by authors. I have set that Woocommerce products allow for authors on the product page, but I am struggling to notify them once their product has been published.

    I would love any help you can offer.

    Thank you so much.
