Force minimum age

Update: we’ve added a new filter in version 3.1.3 that is named “woocommerce_sco_min_age”.

You can use it in this way for instance which would apply 18 for all products and if you’ve set a higher age requirement for a specific product, it would use that instead:

add_filter( 'woocommerce_sco_min_age', function ( $min_age ) {
    return max( $min_age, 18 );
} );
