functions – Execute PHP code only with specific user role

Question

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.
        'id'            => 'qty_args',
        'label'         => __( 'Quantity settings', 'woocommerce' ),
        'value'         => empty($values) ? 'no' : 'yes',
        'description'   => __( 'Enable this to show and enable the additional quantity setting fields.', 'woocommerce' ),
    ) );

    echo '<div class="qty-args hidden">';

    woocommerce_wp_text_input( array(
            'id'                => 'qty_min',
            'type'              => 'number',
            'label'             => __( 'Minimum Quantity', 'woocommerce-max-quantity' ),
            'placeholder'       => '',
            'desc_tip'          => 'true',
            'description'       => __( 'Set a minimum allowed quantity limit (a number greater than 0).', 'woocommerce' ),
            'custom_attributes' => array( 'step'  => 'any', 'min'   => '0'),
            'value'             => isset($values['qty_min']) && $values['qty_min'] > 0 ? (int) $values['qty_min'] : 0,
    ) );

    woocommerce_wp_text_input( array(
            'id'                => 'qty_max',
            'type'              => 'number',
            'label'             => __( 'Maximum Quantity', 'woocommerce-max-quantity' ),

            'custom_attributes' => array( 'step'  => 'any', 'min'   => '-1'),
            'value'             => isset($values['qty_max']) && $values['qty_max'] > 0 ? (int) $values['qty_max'] : -1,
    ) );

    woocommerce_wp_text_input( array(
            'id'                => 'qty_step',
            'type'              => 'number',
            'label'             => __( 'Quantity step', 'woocommerce-quantity-step' ),
            'placeholder'       => '',
