Interesting issue. A client found out that if you push the “enter” on your keyboard while on the WooCommerce Checkout page, the form will be automatically submitted. Ouch! What if the customer wanted to use a different shipping method? What if “enter” is pushed by mistake? So, here’s how you disable it.
Just go to the official WordPress Plugin directory here to download it.
2. Create a new “code block” and add this code
3. Select the checkout page from the right panel
…and the checkout form page won’t submit with the keyboard enter!
