FlexExt Hide Quantity Field & Single Item Enforcer Pro streamlines checkout for digital products, unique items, art pieces, event tickets, and services in OpenCart. Hide distracting quantity input boxes, increment/decrement steppers, and cart quantity selectors on product pages, category grids, search results, and checkout — while enforcing a strict single-quantity limit (Qty = 1) across the entire store.

Eliminate Accidental Duplicate Purchases & Simplify Buying

When selling software licenses, digital downloads, courses, or one-of-a-kind handmade goods, allowing customers to add multiple quantities creates confusion, accidental duplicate orders, and customer service headaches. FlexExt provides clean, rule-based quantity enforcement.

Hide Quantity Inputs

Completely hides quantity fields, plus/minus steppers, and labels on product pages, category lists, and modules.

Strict Single-Item Enforcer

Automatically restricts cart quantity to exactly 1. If a customer clicks Add to Cart again, quantity stays locked at 1.

Per-Product & Category Rules

Apply globally to all products, or target specific categories (e.g. Software, E-books, Services) or individual products.

Cart Page Lock

Disables quantity editing on the shopping cart and checkout pages, preventing customers from modifying numbers.

1-Click Direct Buy Ready

Pairs perfectly with direct checkout workflows, skipping redundant cart review steps for digital goods.

Journal 3 & Theme Compatible

Rigorously tested with Journal 3, Fastor, Basel, One Page Checkout, and standard OpenCart default themes.

Absolutely. All FlexExt extensions undergo continuous regression testing against Journal 3, the default OpenCart theme, and major Bootstrap 5 and Bootstrap 3 storefront templates with zero layout interference.

The extension supports PHP 7.4, 8.0, 8.1, 8.2, and 8.3. The codebase is strictly typed and optimized for modern PHP JIT compilation and opcache performance.

Not at all. Performance is our primary benchmark. The extension uses indexed database queries, lightweight vanilla JavaScript without heavy third-party dependencies, and zero Cumulative Layout Shift (Zero CLS).

Yes, 100%. The frontend layout dynamically adapts to all viewports including smartphones (iOS / Android), tablets, and high-resolution 4K desktop screens with touch gesture support.

You can download updated .ocmod.zip packages directly from your flexext.dev customer portal. Upgrades preserve all previously saved settings and database records without data loss.

Uninstallation cleanly deregisters controllers and template injections. Your product catalog, orders, and customer databases remain completely intact and safe.

Yes, full multi-store support is built into the architecture. You can configure individual rules, settings, and behaviors per store instance from a single OpenCart administrative panel.

Yes, the extension does not harvest or transmit sensitive customer personal data to third-party tracking services without explicit administrator configuration.

Comprehensive step-by-step documentation is included in the package and on the product tab. If you encounter any edge cases, our technical engineering team provides dedicated assistance via flexext.dev.

No. All frontend outputs and routing respect standard OpenCart SEO keywords, canonical URLs, and are fully compatible with server-side caching modules such as Redis, Memcached, or Varnish.

We stand behind our software with a 100% functionality guarantee. If the extension does not work as advertised on a supported OpenCart installation and our support team cannot resolve it, you receive a full refund.
