WooCommerce: Get Product / Order Cross-Sells

Getting the list of cross-sells for a WooCommerce product is actually super easy (yes, it’s one line of PHP). But what if you need to “calculate” the list of cross-sells for an entire order, made of different products?

In this short tutorial for developers we’ll see both: how to get the cross-sell IDs for a product, and how to get the entire range of cross-sells based on what’s been purchased in a given order. Enjoy!

WooCommerce: See If Product ID Belongs To a Grouped Product

Grouped Products are part of WooCommerce core and let you “add similar (think materials, design, etc.) products to a single grouped product. This allows the customer to add products […] to their cart on one page instead of navigating to several different pages to do so” (WooCommerce docs).

It may happen during your coding career that you need to know whether a given Product ID is part of a Grouped Product (so, it’s a “child” of a Grouped Product) – the snippet below will help with that. Enjoy!

WooCommerce: My Account Registration Anti-Spam Honeypot

Here’s my personal attempt to fight against the WooCommerce My Account Page registration spam, without installing yet another captcha plugin.

I’m pretty sure this solution is not perfect, because spam bots are very “smart”, but it can help prevent most fake registrations.

The way I built it, is by adding a custom input field to the My Account Register form with an empty value. Hidden via CSS, this is not visible to the user – but it is visible to spam bots, which will try to post a value. The trick here is the validation check; an error will be generated if the input has a value, and therefore should prevent most fake registration to go through.

Take a look at the code, test it, and enjoy!

WooCommerce: Allow CSV Product Export By Tag

Ok, this is a little hacky and pretty manual, but it happened to me in the past that the inbuilt WooCommerce CSV product export was just not enough.

In other words, the default product export that you can find by clicking the “Export” button on the “Products” WordPress Dashboard screen, gives you the option to export all products to a CSV. You can also refine the list by product type and product category, so that you can export specific products only.

What’s missing there is a “product tag” filter, so this workaround will let you do just that – define a product tag slug in the snippet below, and your export list will be automatically filtered by that.

Of course, you could find a dynamic way of doing that, but for now we’ll keep this manual and hardcoded into the PHP function. Enjoy!

WooCommerce: Search Products By Custom Field (Backend)

In WooCommerce, there are two kinds of search: the customer one (frontend) and the admin one (backend). We’ve already covered how to let customers search into custom field values on top of the default product title and description, so this time we’ll talk about the backend search.

Let’s say, as a WooCommerce store admin, that you’ve added a product custom field (e.g. “gtin“), and you want to make sure the backend search also returns products where “gtin” is equal to the search term. The snippet below will help you do that. Enjoy!

WooCommerce: Add to Cart Pre-defined Quantity Selectors

I seriously spent more than usual trying to write a decent title. Still, I’m not 100% sure I’ve explained it well – so here’s some more context.

The WooCommerce Single Product Page add to cart form features a quantity input and an add to cart button. Super simple. Customers can define a quantity and add the current product to the cart.

Now, let’s imagine you want to change this experience based on your business requirements, and instead of the quantity input and add to cart button you want to show 3 buttons: “Add 1 to the cart“, “Add 2 to the cart“, “Add 3 to the cart“.

And if you can match this with a bulk quantity discount functionality, you can even change the messaging to e.g. “Add 1 to the cart“, “Add 2 to the cart and save $X“, “Add 3 to the cart and save $Y“…

So, let’s see how to hide the default add to cart form, and instead show buttons that allow the customer to add to cart a pre-defined product quantity (for simple products). As per this screenshot:

WooCommerce: Allow Order Editing For Custom Order Status

WooCommerce admins are allowed to “edit” an order only when this is in the “on hold” or “pending payment” status. By “edit” I mean having the chance of modifying or adding products, fees, shipping and recalculating the totals, which are not allowed once the order has been placed (“processing“, “completed“, etc.).

However, there are many reasons why you’d want to have the right to edit a processing, completed, or custom status order – of course as long as you don’t end up changing the total, as customers already paid at that stage.

Think about the following scenarios:

you customized the items table and added a custom field, and you want to set the custom field value when the order is “processing“
you need to edit the shipping method name AFTER checkout, and you want to be able to rename it when the order is “completed“
you need to add a fee and a discount of equal amounts (so that the total stays the same) before completing the order

Either way, let’s enable the little “pencil icon” on a custom order status, so that the admin can customize the order whenever they wish!

WooCommerce: Redirect Specific Category To Product Page

Especially when you have many WooCommerce product categories, it may happen some of them have a single product. Although this is a rare scenario, let’s see how easy it is to redirect customers directly to the single product page in case you don’t want them to see the category page first. Enjoy!

WooCommerce: Get Total Sales By Product Category

It’s easy enough in WooCommerce to get/calculate product sales. What’s difficult, on the other hand, is calculating the total amount of sales for a specific category, because there is no core function that already does that.

Why sales by category – you may ask? Well, to me, that’s a very important metric. For example, I sell both consulting and non-consulting products on this same website, so it’s important for me to keep track of category sales year-on-year, especially when my goal is reducing 1-to-1 client work while increasing scalable product sales such as courses, plugins and memberships.

In this quick tutorial, we will first get the “WooCommerce orders that contain a target product category”, and after that we will loop through the array to calculate the total sales for that specific category. Sounds difficult? No worries – just copy and paste the snippets below.

WooCommerce: Update Self-Hosted Plugin @ WP Dashboard

In this million-dollar tutorial you will learn how to update a custom (WooCommerce) plugin that you host somewhere, directly from the WordPress dashboard.

I thought the WordPress dashboard could only notify you of plugin updates and let you exclusively update plugins that are on the WordPress repository, but I was wrong!

Since I started selling WooCommerce plugins here on Business Bloomer, I had to find a way to let customers update them automatically right from their WP admin.

Thankfully, there are 2 hooks that come to the rescue: ~~pre_set_site_transient_update_plugins~~ update_plugins_{$hostname} and plugins_api. With these two filters, you can tell WordPress that your custom plugin ZIP file is downloadable at a given public URL, show a notification to the customer that a plugin update is available, let them update with 1 click, and optionally let them enable auto-updates.

So, let’s see how I run my plugin business. Enjoy!

WooCommerce: Email Admin Upon Fatal Error

WooCommerce has a nice feature when it comes to WordPress Error 500 / Fatal Error – it logs the error and all the information regarding it inside the WooCommerce Status > Logs > Fatal Errors area.

My problem is that sometimes these errors occur in the backend, so they may not trigger the WordPress built-in email that notifies the admin about the problem.

What I want to try (please test it on your development website first, and not on your live website), is a way to get an email each time WooCommerce logs an error, so that I can go in and fix it immediately. Enjoy!

WooCommerce: Disable Checkout Field Autocomplete

By default, WooCommerce adds the “autocomplete” attribute to almost all checkout fields. For example, “billing_phone” has “autocomplete=tel”, “billing_country” has “autocomplete=country” and so on.

When logged out or if the logged in user has never done a purchase before, the WooCommerce Checkout page fields are possibly autofilled by the browser based on saved data / addresses.

Today, we’ll take a look at how to disable this autofill behavior, so that the customer is forced to enter data inside an empty input, and maybe in this way you can apply your custom validation or pattern, such as a specific phone number format. Enjoy!

WooCommerce: Get EU, EU VAT, EEA, SCA Countries

When you deal with conditional payment gateways, or conditional notifications, or conditional content, you may need to use to check the current billing country against an array of countries (in plain English, you may want to know if the customer is based in a specific World area), such as the European Union.

Thankfully, WooCommerce gives us a nice prebuilt function so that we don’t need to create the array of EU countries manually. On top of that, it’s easy to manipulate that array in order to add / remove countries for different uses, such as getting the list of EEA (European Economic Area) countries or SCA (Strong Customer Authentication) countries. In this post, I will give you some shortcuts to “calculate” these arrays, so that you don’t need to bother doing it.

Please note, EU, EEA and SCA countries are constantly changing, so these arrays are updated to the date you see on top of this post. Enjoy!

WooCommerce: Add Product To Order After Purchase

On Business Bloomer I sell a bundle of products, and I use no Bundles plugin for that. So the challenge was to programmatically add a list of products to the order upon purchase, once the bundle product is purchased.

This is an amazing way to save time for the customer, as they don’t need to manually add each product to the cart. In the background, after a successful purchase, some magic code (that you find below) adds products to the order, sets their price to $0.00 (so that the order total is not altered), and saves the order. Enjoy!

WooCommerce: Fix Google Search Console “No global identifier provided” Error

If you registered your WooCommerce website on Google Search Console for monitoring your SEO efforts and search appearance errors, you probably got this “No global identifier provided (e.g. gtin, brand)” email notification at some stage. I got it too.

Search Console optionally requests you set a unique product GTIN structured data for all your products – I believe in case you wish to sell on Google Shopping – and therefore sends you this error notification whenever a product is missing this.

You could use a WooCommerce GTIN plugin from the WP repo, yes. Or you could be smart, and programmatically set the GTIN to the same value of the product SKU, as long as all your products have a unique SKU value. Today, we will cover the latter. Enjoy!

WooCommerce: Set Product Price Based On Other Products!

I’m Italian and I love exclamation marks! I also love WooCommerce customization, as you may know. This time I want to show you how I programmatically define the price of my WooCommerce Mini-Plugin All-Access-Bundle product… based on other products.

The backstory: as of today, I sell 18 WooCommerce plugins, and soon I should reach the 400 mark if all goes well. So, I came up with the idea of creating a bundle, and let customers gain access to all of them within a single, discounted purchase.

Yes, I could have purchased a Product Bundle plugin… but I wanted to see if I could create a bundle out of a Simple product.

The only requirements were: set the regular price based on the total price of the plugins, set its sale price based on a percentage discount, automate this so I don’t need to manually update the bundle price every time I add a new product, and add all plugin products to the order upon bundle purchase (we will see this in another snippet). Enjoy!

WooCommerce: Display Sale Price End Date @ Shop & Single Product Page

WooCommerce allows you to “schedule” the product sale price – you can define a start date and an end date, so that you can run your promotion automatically.

However, for some reason, this information is only visible to the admin. It would be awesome to show the “sale price end date” to customers as well, don’t you think? So, let’s do it!
