FAQ

Does Minimum require WooCommerce?

Yes. Minimum is a WooCommerce extension and needs WooCommerce 8.0 or later active. With WooCommerce missing the plugin stays dormant and shows an admin notice rather than erroring.

How do rules combine?

For each constraint, min, max and step, the most specific matching rule wins, resolved independently: a product rule beats a category rule, which beats the global rule. Leave a field at 0 to ignore that constraint.

How do I ignore a constraint?

Leave its field at 0. A minimum or maximum of 0 is not enforced; a step of 0 or 1 is treated as no step. A rule row where every constraint is empty is dropped when you save.

Can I turn rules off without deleting them?

Yes. The Enforcement switch on the settings screen stops every rule and the order total being applied at the cart and checkout while keeping them saved. Turn it back on to resume.

Does it work with the block cart and checkout?

Yes. Every check reads the cart contents rather than a specific template, so the same notices appear and checkout is blocked in both the classic and block-based cart and checkout. Minimum is also declared compatible with the Cart and Checkout blocks and with HPOS.

Where are rules enforced?

On add-to-cart, when the cart page renders, and again at checkout. The add-to-cart check counts what is already in the cart for that product, so a rule cannot be slipped past by splitting one purchase across several adds.

Can I set a minimum order value rather than a quantity?

Yes. The Minimum order total field requires the cart subtotal to reach a value before checkout, independently of the per-product quantity rules. Set it to 0 to disable.

Can I customise the notices?

Yes. Each of the four notices is editable on the settings screen. The default minimum notice, for example, is You must buy at least {min} of "{product}".. Available tokens are {min}, {max}, {step}, {product} and {total}, but only the tokens relevant to each message are substituted. In the order-total notice, {min} is the required floor and {total} is the shopper’s current subtotal.

What if I set the maximum below the minimum?

Minimum drops the maximum on save and keeps the minimum, so the rule never produces a contradiction that no quantity could satisfy.

Is it compatible with HPOS?

Yes. Minimum declares compatibility with HPOS (custom order tables) and the Cart and Checkout blocks. It reads cart contents rather than legacy order internals.

Can developers adjust the resolved rules?

Yes. The minimum/product_constraints filter runs after the global/category/product rules are merged and lets add-ons override the resolved {min, max, step} for a given product or variation ID. This is the same hook Minimum Pro uses for per-product overrides. See Configuration for an example.

Does it connect to external services?

No. Minimum is self-contained, no bundled libraries, no jQuery on the settings screen, and no calls to external services.

What happens when I delete the plugin?

The uninstall routine removes the minimum_settings and minimum_db_version options. There are no custom tables, so nothing else is added to or left in your database.

Free vs Pro

The free edition is the full rules engine: per-product, per-category and global min/max/step quantity rules, a minimum order total and customisable notices, enforced on add-to-cart and at the cart and checkout. Minimum Pro adds per-product min/max/step overrides today; per-role rules, scheduled rules, CSV import and conditional logic are on the roadmap.
