WooCommerce: Item Custom Field @ Edit Order Page

Alright, this title may not really help you understand what I mean, so let’s put it in another way. When, as an administrator, you edit an order and are in the Order Items table, you have the chance to edit the item quantity, subtotal and discounted price (see screenshot below).

Now, what if you also want to have the freedom to display and edit another custom field, so that it is saved inside the order once you hit the “Save” button?

This could be useful for custom setups – for example let’s imagine the admin has the necessity to also define the “shipped quantity”, so that they know exactly if a specific order has been entirely fulfilled or requires a second shipment to get completed.

Either way, see the screenshot below, play with the snippet, and see how it goes. Enjoy!

Here’s a brand new editable column I was able to add to the Edit Order page inside the Order Items table. It works exactly in the same way as the “Qty” field, except that it is a custom field.

Where to add custom code?

You should place PHP snippets at the bottom of your child theme functions.php file and CSS at the bottom of its 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 guide "Should I Add Custom Code Via WP Editor, FTP or Code Snippets?" and my video tutorial "Where to Place WooCommerce Customization?"

Does this snippet (still) work?

Please let me know in the comments if everything went 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.
