Arik Product Fields — WooCommerce Custom Fields, Buy Now, Enquiry Form & Coupon

Dynamic fields (populated from the current product):

• Categories rendered as checkboxes built from the product’s own categories
• Tags rendered as checkboxes built from the product’s own tags

Feature highlights

• Drag-and-drop field builder powered by jQuery UI Sortable. Click any field type in the palette to add it. Drag rows by the handle to reorder. Inline editor with per-type controls.
• Per-product field assignment through a dedicated Product Data tab. Pick which fields appear on which products. Leave it empty to use global-scope fields.
• Buy Now button that skips the cart and lands the customer on checkout (or cart your choice).
• Enquiry form in an accessible modal. Sends email to admin, stores submissions as a custom post type, and recommends Contact Form 7 as a more robust alternative.
• Coupon code box on the single product page with four position options.
• Checkout modifications add an optional Order Reference field, make phone optional, soften default placeholders.
• Hide SKU and Categories/Tags on single product pages globally or per-product.
• Tri-state per-product overrides for Buy Now and Enquiry: “Use global setting”, “Show”, or “Hide”.
• Configurable field position render fields before/after price, before/after Add to Cart, or before/after Buy Now.
• Design tab style the frontend fields without writing CSS: container background, border, radius, padding and spacing, one- or two-column layout, label typography, input colours and sizing, radio/checkbox pill shape and selected state, button colours, plus an Additional CSS box. Four presets and a live preview that renders with your storefront’s own stylesheet. Ships switched off, so upgrading never changes how your product pages look.
• Support & Docs admin page with the full developer hook reference and code examples.
• Translation-ready with wp_set_script_translations() for the builder UI.

Security

• WordPress nonces on every form and AJAX endpoint.
• Capability checks on every admin action ( manage_woocommerce , edit_product ).
• Honeypot field plus per-IP rate limiting on the enquiry form.
• Type-aware sanitization with a strict allowlist per field type.
• Output escaped per WordPress.org guidelines ( esc_html , esc_attr , esc_url , wp_kses_post ).
