Woocommerce check out quantity and price not updating

I have this code in my WordPress to define the minimum quantity. It works fine at the product single page and “add to cart” page.

I want the quantity and price updated automatically on the shopping cart, add to quote and checkout pages.

I don’t want users to “checkout” if the quantity is less than 12 and the price is calculated accordingly.

add_filter( ‘woocommerce_quantity_input_args’, ‘woocommerce_quantity_changes’, 10, 2 );

function woocommerce_quantity_changes( $args, $product ) {

$args[‘input_value’] = 4; // Start from this value (default = 1)
$args[‘max_value’] = 10; // Max quantity (default = n/a)
$args[‘min_value’] = 2; // Min quantity (default = 1)
$args[‘step’] = 2; // Increment/decrement by this value (default = 1)

return $args;
}
