描述
Every WooCommerce store has a checkout page, but the default field set rarely fits every business. NINJA Checkout Fields gives shop managers a clean admin screen (under WooCommerce Checkout Fields) where they can:
- Enable or disable any standard checkout field (Billing, Shipping, Additional/Order).
- Mark fields as required or optional — override WooCommerce’s defaults to fit your workflow.
- Rename the label shown to the customer, without editing template files or child themes.
- Set a placeholder (hint text inside the input) per field.
- Reorder fields with simple priority numbers or ▲/▼ buttons — lower priority = earlier on the form.
- Live preview that shows the derived checkout layout — exactly what your customers will see — updating as you edit.
Everything is saved in a single WordPress option. No database tables, no rewrite rules, and no external requests for managing your checkout (the only opt-in exception is the “NINJA Updates” email subscription described below). Activate, configure, done.
Protected fields: billing_country and billing_email can never be disabled because WooCommerce requires them to complete order processing. The plugin enforces this server-side regardless of what the admin UI sends.
Reset: One click restores the full WooCommerce default field set.
WooCommerce integration
NINJA Checkout Fields declares HPOS (High-Performance Order Storage / Custom Order Tables) compatibility and uses the standard woocommerce_checkout_fields filter so it’s compatible with any WooCommerce version that exposes that filter (8.0+). It does not modify database tables, templates, or core files.
Stay updated (optional)
The admin screen has an optional “NINJA Updates” card: tick the consent box and enter your email to hear about plugin updates and new NINJA modules. It is entirely opt-in — nothing is sent unless you submit that form — and you can unsubscribe at any time with one click. This is the only feature that ever contacts an external service.

Field manager — at-a-glance KPI cards plus per-field controls (Enabled, Required, Label, Placeholder, Priority) for the Billing, Shipping, and Additional sections. 
Live preview — the derived checkout field list in priority order, exactly what customers will see, with one-click Save and Reset to WooCommerce Defaults.
安装
- Go to Plugins Add New, search for “NINJA Checkout Fields”, and click Install Now — or upload the ZIP under Add New Upload Plugin.
- Click Activate.
- Open WooCommerce Checkout Fields in the admin menu.
- Enable, disable, relabel, reorder, and set placeholders as needed.
- Click Save Changes. Your checkout updates immediately.
WooCommerce must be installed and active. If it is not, the plugin shows an admin notice and does nothing else.
常见问题
-
Can I disable the billing email or country?
-
No — and that’s deliberate. WooCommerce cannot process an order without those two fields. The plugin protects them server-side; the UI makes it clear they’re required.
-
Will this break my existing orders or customer data?
-
No. The plugin only affects the checkout form presented to new customers. Existing orders are untouched. Overrides are stored as a single WordPress option, so you can reset at any time.
-
Does it work with HPOS (High-Performance Order Storage)?
-
Yes. HPOS compatibility is declared and the plugin does not read order data at all.
-
Does it make any external requests?
-
Not unless you ask it to. All checkout-field management runs entirely inside your WordPress install. The single exception is the optional “NINJA Updates” card: only if you tick its consent box and submit your email does the plugin contact ninja.si to register your subscription. Leave it alone and nothing is ever sent.
-
What happens if I deactivate the plugin?
-
The
woocommerce_checkout_fieldsfilter is no longer applied, so the default WooCommerce fields come back immediately. Your saved configuration is preserved and restored when you reactivate.
