WooCommerce: Check if Product ID is in the Order

Once a customer places an order, you might want to know if such order contains a given product ID. you can use this for tracking purposes, redirect to a custom thank you page or run your custom functions.

Either way, checking this is quite simple thanks to the “woocommerce_thankyou” hook which runs on the order received page. 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

  1. You know, you are the best ๐Ÿ˜‰

  2. Hi Rodolfo,

    If I wanted to check if a certain ordered item in an order has a certain shipping class, and I want a notice to display a notice in the order processing email should that item be present – how would I adjust this code to achieve that?

    Thanks,
    Ryan

    1. Hey Ryan! In a previous blog, I showed how to loop through the cart to look for shipping classes (just do a search on Business Bloomer for “shipping class” and you’ll find it). The order is slightly different, but you can learn the basics from that article anyway ๐Ÿ™‚

  3. not working for product id now . i think woocommerce chnages its structure

    1. Hey Ranjit thanks for your comment! I don’t think they have changed it – can you try one more time please?

  4. Your video images are pointing to your staging site, I would do a search and replace on any of those so they don’t make a staging authentication box appear.

    1. Dear Steven, thank you so much for spotting that issue! I’m having quite a few issues with the staging right now, but thankfully this has now been sorted. Can you please try again and report back? I really appreciate your help! Cheers, R

  5. Is there a way to do this with the product category instead of ID? I’ve been searching for a solution with no luck.

    1. Hello Tia, thanks so much for your comment! Answer: there is always a way ๐Ÿ™‚

      Take a look at this guide https://businessbloomer.com/woocommerce-conditional-logic-ultimate-php-guide/ and try to see if there is a conditional rule you can apply to the products if they belong to a given category slug ๐Ÿ™‚

      Let me know
