I have a WordPress website with woocommerce and I want to set a minimum order quantity for products. I have found code online which does exactly what I need it to do and it works perfectly.(the code is below) The only problem is, I want to be able to set a minimum order quantity for each product but only execute it on a certain user role. I have 2 different prices for each product. A regular price for "normal" customers and a wholesale price for b2b users. I have installed a plugin called "b2bking" which takes care of this and allows me to have different prices depending on user role. The thing is, if you are a b2b user then you benefit from cheaper prices but depending on the product there is a minimum order quantity.
So long story short. I'm now able to set a minimum order quantity for each product but I only want it to work on the product page if the user role is a b2b user.
Here is the code:
// Displaying quantity setting fields on admin product pages add_action( 'woocommerce_product_options_pricing', 'wc_qty_add_product_field' ); function wc_qty_add_product_field() { global $product_object; $values = $product_object->get_meta('_qty_args'); echo '</div><div class="options_group quantity hide_if_grouped"> <style>div.qty-args.hidden { display:none; }</style>'; woocommerce_wp_checkbox( array( // Checkbox.
