How to fix input button name on WooCommerce

Steps for WooCommerce

1. Empty-value input buttons in WooCommerce most often originate in theme template files, not WooCommerce core.
2. In your WordPress admin go to Appearance → Theme File Editor (or use a child-theme folder via FTP/SSH).
3. Search template files for `<input type="submit"` with an empty or missing value — common locations are `woocommerce/templates/cart/cart.php`, `checkout/form-checkout.php`, and widget templates.
4. Edit the relevant template in your child theme (copy from the plugin folder first if not already overridden): add `value="Place Order"` or the appropriate label.
5. Alternatively, install the free WP Accessibility plugin and use its button-label helpers, or add a small code snippet to `functions.php` using `woocommerce_order_button_text` filter to ensure submit buttons carry a label.
6. Test with the axe DevTools browser extension after saving.

What is input button name?

An "input button" is any clickable button created with an HTML `<input>` tag of type `button`, `submit`, or `reset`. Its accessible name — the text a screen reader announces when a user focuses on it — comes from its `value` attribute. When that attribute is missing or empty (`value=""`), the button has no accessible name at all. A screen reader user hears something like "button" with no description, giving them no idea what will happen if they press it. WCAG Success Criterion 4.1.2 (Name, Role, Value) requires that every interactive element, including buttons, has a programmatically determinable name.

Screen reader users — which include millions of people with visual, motor, or cognitive disabilities — cannot use your site's key actions (Add to Cart, Search, Subscribe, Checkout) if the buttons that trigger them have no accessible name. This is a direct WCAG 2.1 Level A violation, the most fundamental compliance level, and exposes your store to legal risk under ADA Title III (US), EN 301 549 (EU), and equivalent laws worldwide. Beyond legal risk, an unlabelled submit button on a checkout or contact form causes real cart abandonment and lost conversions. Search engines also look at accessibility signals as a proxy for page quality, so fixing these issues can support your overall SEO health.
