Hi, {{first_name|friend}}. 👋
Welcome to Issue #183 of Loop WP!
Last week was a quick WooCommerce tutorial on a common feature I use for my Shopify clients, plus some bonus code!
This week, we are revisiting WooCommerce Address Autocomplete as I share what went wrong with my code and another free plugin you can now use!
Let’s go! 👇

Revisiting Address Autocomplete
Back in Issue 181, I took a look at the Address Autocomplete feature in WooCommerce in 10.3. I released some code, but found issues with:
The new Places API (so I used the current API, which is being retired).
The Block Checkout (my code was only working in the Classic checkout).
Thankfully, Nadir Seghir (Building Checkout in WooCommerce) came to the rescue.
After reviewing Nadir’s walkthrough, and aside from the APIs, I saw many differences in our approaches, and that’s where I fell down. 👇
Integration Method
My plugin - Manually injects JavaScript and tries to hook into WooCommerce forms directly with jQuery.
Nadir's plugin - Properly extends
WC_Address_ProviderandWC_Integrationclasses, and registers with WooCommerce's native address autocomplete system using:window.wc.addressAutocomplete.registerAddressAutocompleteProvider()
Block Checkout Compatibility
My plugin - Uses jQuery selectors for specific field IDs (
#billing_address_1), which don’t exist in Block Checkout.Nadir's plugin - Uses WooCommerce’s abstracted provider system that works with both Classic and Block Checkouts.
🧠 You can read more on these abstracted providers (which are designed to cut down on code):
Nadir talks more about the abstracted code (which you can view in GitHub) in his tutorial, which we will dig into now. 👇
Nadir’s Solution & Free Plugin
If you missed my newsletter on this, you need to know that in WooCommerce 10.3, WooCommerce added support for address autocomplete, but no provider is bundled, so merchants must plug in their own.
Nadir Seghir, very kindly, went above and beyond in reply to my tweet and followed up with a detailed tutorial using Claude and code edited by Nadir.
Nadir is making the plugin available on the WordPress Plugin Repository, but in the meantime, you can download it from GitHub.
A huge thank you to Nadir for this and for making the code available to the community.
A Small Issue
I found an inconsequential issue with HPOS compatibility (which my plugin didn’t trigger, as it wasn’t functioning correctly) that displayed a warning in the WP Admin area:
“WooCommerce has detected that some of your active plugins are incompatible with currently enabled WooCommerce features."
This warning appears because WooCommerce detects that Nadir’s plugin declares compatibility with the Address Autocomplete feature, but the plugin file lacks the required compatibility declaration headers.
It’s a non-issue because the plugin will work with HPOS because it doesn't interact with orders at all; however, it’s nice to get rid of the warning, which we can do by using a declaration before the before_woocommerce_init
// Declare HPOS compatibility
add_action( 'before_woocommerce_init', function() {
if ( class_exists( \Automattic\WooCommerce\Utilities\FeaturesUtil::class ) ) {
\Automattic\WooCommerce\Utilities\FeaturesUtil::declare_compatibility( 'custom_order_tables', __FILE__, true );
\Automattic\WooCommerce\Utilities\FeaturesUtil::declare_compatibility( 'address_autocomplete', __FILE__, true );
}
} );My Updated AutoComplete Plugin
🎉 As well as fixing the inconsequential issue above, my updated version of the plugin now works on both the Classic and Block Checkouts (thanks again, Nadir), and I’ve made some changes to my original plugin:
Removed the inline CSS (now using default styles)
Adding a settings screen to the WooCommerce Integrations to allow more configuration:
Enable/disable the autocomplete.
Add an obscured API key (instead of editing plugin files).
Adding country restrictions (instead of editing plugin files).
✅ You can view an updated version of my plugin on GitHub, which I have now made public and created a repo.
(My plugin remains a single file, but if you want to edit the JS separately, then you can move this into a new file and call it autocomplete.js)
Before You Go
This experience has taught me that it’s hard to code for both the Classic and Block Checkout. WooCommerce’s own Checkout Field Editor is not compatible with the Checkout Block.
Having said that, there are lots of great resources from Woo for extending/customising the Block Checkout:
Checkout Block documentation.
Adding custom fields to the WooCommerce Checkout Block - Brian Coords.
Getting started with Cart and Checkout extensibility.
Tutorials:
Integrating Protection with the Checkout Block.
How to Add Additional Fields to the WooCommerce Checkout Block.

That’s it for this week. 👋
