The “Add to cart” validation controls in the Min Max Step Quantity Limits Manager for WooCommerce decide what happens when a customer tries to add a quantity that breaks your rules: allow it, block it with a notice, or silently correct it. This is a free feature.
Steps #
- Go to WPFactory > Quantity Manager > General (also reachable at WooCommerce > Settings > Product Quantity).
- Set “Add to cart” validation (
wpfmmsq_add_to_cart_validation) to one of:- Do not validate: no check on add to cart.
- Validate and add notices: block the invalid quantity and show a notice (recommended for most stores).
- Validate and auto-correct quantities: adjust the quantity to the nearest valid value automatically.
- If you chose auto-correct, set Step auto-correct (
wpfmmsq_add_to_cart_validation_step_auto_correct) to Round, Round up or Round down. - Click Save changes.
