Update the Modified Date in a WooCommerce Order

If you run a script to update order properties in WooCommerce, you may want to update the “post_modified” date along with the other updates. Many third-party integrations rely on the post_modified date to sync any order changes or updates.

Here’s how you can easily update the modified date (assuming you have the order object):

$order->set_date_modified( time() );

Here’s a full example which fetches the order, updates the date, and saves the order.

$order = wc_get_order( 123 );
$order->set_date_modified( time() );
$order->save();

Launching an Extension in the WooCommerce Marketplace

I launched an extension in the WooCommerce Marketplace! It’s been three years since I came up with the initial idea and it’s exciting to see it being sold on WooCommerce.com.

For anyone interested in selling WooCommerce products, I wanted to share some thoughts on the process.

Coming Up With A Product

The extension idea originally came out of a client project. A company I worked with acquired a lot of their new customers through Facebook advertising, and they wanted a way to offer those new customers a big discount on their first purchase.

The first version of the extension took a couple days to build. It simply added a checkbox to the coupon editor for marking coupons as “new customer only” and validation on checkout. From that basic idea, I then started to add other restriction options I thought would be useful.

WooCommerce client work is great source of extension ideas because it requires solving a real need for a customer (and is something they’re willing to pay for).

To get the extension idea accepted to the WooCommerce Marketplace, I also had to prove that others wanted this functionality. Luckily, a number of people had also requested this on the WooCommerce idea board as well.

Example Cart Restrictions in WooCommerce

I’ve been working with a “Trial Product” in a WooCommerce store which needs to be the only item in the cart during checkout due to shipping requirements (and because it doesn’t make sense to order a trial if you’re also going to order the actual product).

To make this clear to the customer, I’ve restricted what can be added to the cart in specific situations:

1) If the “Trial Product” is already in the cart, additional products should not be added. WooCommerce will instead display a notice asking the customer to remove the “Trial Product” from their cart if they wish to add different products.

2) If products are already in the cart, and the customer attempts to add the “Trial Product”, a notice will display asking the customer to remove the other items from their cart first.

Automated WooCommerce Testing with Ghost Inspector

WooCommerce sites are made up of a complex set of integrated parts. There’s WordPress, WooCommerce itself, other third-party plugins, and a theme. Each of these components require frequent updates and has the potential to break critical functionality on your site. This is why it’s critical to have automated tests.

For a WooCommerce site I used to work with, we had a checklist of items we would manually run through after any major update:

  • Verify products on home page look correct and load
  • Test “Add to Cart” button
  • Test removing item from cart
  • Verify all product on /shop page look correct
  • Test complete checkout with Stripe for guest checkout
  • Test complete checkout with PayPal for guest checkout
  • Test complete checkout with Stripe with coupon for guest checkout
  • etc.

Needless to say, this took a lot of time. Thankfully, tests like this can all be automated using Ghost Inspector.

Subscription Toggle in WooCommerce

In WooCommerce subscription products and standard products can’t be combined. For example, if you’d like to offer customers the option to purchase coffee as a one-time sale or as a convenient monthly subscription, you’ll need to create two separate products on the backend (even though it’s essentially the same product and SKU).

If you’re SEO focused, this might be a concern in terms of duplicate content and splitting page rank. For customers, this also isn’t a great experience. If a customer lands on the one-time product page, they might not know about the subscription option (and vicea versa).

A better example of subscription user experience is Target. If a product offers a subscription option, there’s a radio button toggle with a discount clearly highlighted. Turns out, with a little work, this is also possible to do in WooCommerce. Continue reading

Shopify vs. WooCommerce

A former client contacted me this week because they were thinking about switching platforms for their ecommerce store. The site had originally been built on WooCommerce but they were now considering a switch to Shopify. The main issue is they didn’t want to have to rely on a developer for site updates and wanted a solution they could more easily manage themselves.

To answer their questions, I signed up for a Shopify account and then went through the technical and business requirements one by one. If you’re trying to decide between Shopify and WooCommerce, hopefully some of these notes are useful.

Unit Tests for WooCommerce Extensions

I am completely new to PHP unit testing, but I decided it was time to learn after discovering a critical bug in a small WooCommerce extension I had built for a client.

The extension I built added a feature that allowed administrators to limit specific coupons to new customers only. I had done some manual testing and made sure that new customers could use the coupon and existing customers could not. But there was a logic bug I missed that prevented existing customers from using any coupons, even ones that did not have the “new customer” restriction.

After finding the bug, I knew there were several use cases I would need to check every time an update was made to the plugin:

  • New customer should be able to apply a coupon
  • New customer should be able to apply a coupon with a “new customer” restriction
  • Existing customer should be able to apply a coupon without a “new customer” restriction
  • Existing customer should *not* be able to apply a coupon with the “new customer” restriction

Obviously, checking this manually each time would be rather tedious- which is why I turned to unit tests.
