woocommerce_add_to_cart_fragments not working

Hi @rplofino

It seems woocommerce_add_to_cart_fragments not working from the latest update. Whatever theme, even Storefront having this issue.

Can you please advice as there are a lot of people creating basket count for this filter.

From what I understand, you’re experiencing a problem with the woocommerce_add_to_cart_fragments function after the latest update.

To help us figure out what’s going on, could you send us a copy of your site’s System Status? This will give us a clearer picture of your site’s setup and help us pinpoint the problem. You can find it via WooCommerce > Status. Select Get system report and then Copy for support.

Additionally, could you also provide us with the Stripe error logs (if any) under WooCommerce > Status > Logs.

Once you’ve got that, you can paste them right here in your reply, or use https://pastebin.com/ to paste it there and share it with us.

With this information, I’ll be able to dig deeper and come up with a more precise solution. Meanwhile, you might want to try disabling all plugins except for WooCommerce to check if the issue still occurs. This could help us see if there’s a conflict with other plugins.

Here’s a helpful guide on how to test for conflicts: ?? How to Test for Plugin and Theme Conflicts

Thanks for your patience and cooperation. I’m looking forward to your response. 

Hi Tamrat,

Error: Missing window object: wc_cart_fragments_params. Double check if you have WooCommerce fragments enabled.

I’ve saw similar issue from the internet.

Please advice if there is a method to enable fragment if it is not by default now. I’ve experience it now from 2 of our woo websites.

Hello, it seems this issue is related not only to 7.9.0 but also 7.8.2 at least.

For me the issue is, that when WP Rocket caches the site, it doesn’t update the cart content counts correctly, even though I am using “WP Rocket | Deactivate WooCommerce Refresh Cart Fragments Cache” which solved the issue in older versions.

Hi @hovenberg,
Yeah, I’m using WP Rocket as well and never had this issue until the recent updates.

I believe the issue will spread like a fire when people starting noticing it. Other Woo AJAX somehow affecting as well from my issues now.

My solution was to rollback to older version to make it worked still. But this should resolved as well for the next update. @bisratlearn

Hi everyone!

The Cart Fragments script, responsible for updating the cart widget after a successful add-to-cart event, can cause a performance issue on stores not making use of that functionality. To mitigate this, the script will now only be enqueued if using the Mini Cart widget.

This change was implemented with WooCommerce 7.8.

Stores with similar functionality (e.g. from a theme) that are not using the widget can re-enable this functionality by either adding the widget to one of their widget areas/sidebars or by enqueuing the script manually:

function enqueue_wc_cart_fragments() { wp_enqueue_script( 'wc-cart-fragments' ); }
add_action( 'wp_enqueue_scripts', 'enqueue_wc_cart_fragments' );

If you’re looking for an alternative to the Mini Cart widget that does not suffer from the performance issue, try the Mini Cart Block instead.
