When WooCommerce sends order emails to your customers, by default it only includes the product name in the order items table within the email.
However, it’s possible to add some additional product details here, such as the product SKU or product featured image.
We’d previously written about adding information to WooCommerce order emails so that you could show product SKUs or product images within the WooCommerce order emails for customers. However, the process to do this was changed in a backwards-incompatible way in WooCommerce 2.5.
In previous versions of WooCommerce you were able to filter the entire email output, which made it possible to change whether images or SKUs were included.
However, with WooCommerce 2.5, the filter to change the order items table is still there, but it does not give you all of the data you need to make changes to the order items table in the email in the same way. You don’t have access to the
$args that are used in the template to determine what information to show or hide, so this filter pretty much doesn’t allow you to do anything directly.
If you’re already using WooCommerce 2.5, it’s possible to change the information shown in WooCommerce emails, we just have to be a bit more creative in how we use this filter. If you follow this tutorial, be sure you know how to add custom code to your website and that you’re using WooCommerce 2.5 or newer.
You can add product images to to your order emails with this filter, but we can’t modify the arguments used to get the template directly. Instead, we’ll have to call the
$order->email_order_items_table() function again, but with new arguments to use. The reason this gets tricky is because if we call this function, it will call the filter we’re using, which will again call the function, which will again call our filter…you get the idea. We’ll get an infinite loop.
To modify the email output this way, we’ll need to use a static variable as a flag. This will let us only run our code once so that the email output is modified, then our code will bail out after it’s run the first time.
That’s a wrap! This will change the way the email order items table is output to include product images when emails are sent to customers.
We can use pretty much the exact same code to enable product SKUs in WooCommerce order emails instead of product images.
We’ll use the same snippet as above, but replace:
$args = array( 'show_image' => true, 'image_size' => array( 100, 100 ), );
$args = array( 'show_sku' => true, );
This will add the SKU after the product name in this format:
Product Name (#productSKU) Here’s an example of what this would look like (the images wouldn’t be there of course):
You can also add both SKUs and images to the order emails by adjusting the arguments to include both of them. The image size can be deleted if you want to use the default 32px by 32px size, or you can add your own size by adjusting the values below.
$args = array( 'show_sku' => true, 'show_image' => true, 'image_size' => array( 100, 100 ), );
If you want to have more control over your order email design, you can also consider using a plugin or service to replace your transactional emails. For example, you could consider using Jilt to send emails after orders are completed instead. This would allow you to use an email builder to create emails, including product images and names instead:
You can learn more about Jilt and other ways to improve your emails in our guide to customizing WooCommerce order emails.
Adding product SKUs or product images to WooCommerce order emails is possible, and you can add both if desired, along with changing the size of your image as needed. Remember, the code outlined above is only for WooCommerce 2.5 or newer. If you’re still using an older version of WooCommerce, check out our previous tutorial for code compatible with your WooCommerce version.
