是的，您可以使用woocommerce_get_price filter hook可根据用户角色筛选值并相应返回价格，例如：

add_filter(\'woocommerce_get_price\', \'custom_price_WPA111772\', 10, 2);
/**
 * custom_price_WPA111772 
 *
 * filter the price based on category and user role
 * @param  $price   
 * @param  $product 
 * @return 
 */
function custom_price_WPA111772($price, $product) {
    if (!is_user_logged_in()) return $price;

    //check if the product is in a category you want, let say shirts
    if( has_term( \'shirts\', \'product_cat\' ,$product->ID) ) {
        //check if the user has a role of dealer using a helper function, see bellow
        if (has_role_WPA111772(\'dealer\')){
            //give user 10% of
            $price = $price * 0.9;
        }
    }
    return $price;
}

/**
 * has_role_WPA111772 
 *
 * function to check if a user has a specific role
 * 
 * @param  string  $role    role to check against 
 * @param  int  $user_id    user id
 * @return boolean
 */
function has_role_WPA111772($role = \'\',$user_id = null){
    if ( is_numeric( $user_id ) )
        $user = get_user_by( \'id\',$user_id );
    else
        $user = wp_get_current_user();

    if ( empty( $user ) )
        return false;

    return in_array( $role, (array) $user->roles );
}

你可以试试Customer Specific Pricing for WooCommerce. 使用此插件，您可以为注册用户添加不同的价格。

目前该插件处于初始阶段，但很快就会有更新，以支持其他功能，如基于产品类别的价格。
