Quickbuy button shortcode

Hi,
i updated this plugin from 1.8 to 2.4, all went smooth except one shortcode i was using:

[wc_quick_buy label=”BUY” product=”‘ . $product->get_id() . ‘” qty=”1″ type=”button” htmlclass=”single_add_to_cart_button” css_class=”single_add_to_cart_button” ]

I tried to use both “htmlclass” and “css_class” after digging into your code because my prev shortcode had just the “css_class” attribute.
After i couldn’t get it to work, i went again inside your code and find in this file wp-content/plugins/woocommerce-quick-buy/includes/shortcodes/class-button.php the following:

protected function defaults() {
			return array(
				'label'        => Helper::option( 'button_label' ),
				'product'      => false,
				'qty'          => Helper::option( 'quantity', 1 ),
				'hide_in_cart' => Helper::option( 'hide_if_in_cart' ),
				'css_class'    => Helper::option( 'css_class' ),
			);
		}

Later on in the same file inside output function you have this:

$instance = new Button_Generator( array(
							'type'         => 'link',
							'product'      => $shortcode_product,
							'qty'          => $this->option( 'qty' ),
							'label'        => $this->option( 'label' ),
							'hide_in_cart' => $this->option( 'hide_in_cart' ),
							'class'        => $this->option( 'htmlclass' ),
						) );
						return $instance->html();

As you can see you are looking for “htmlclass” inside the options, but you should instead look for “css_class”. Indeed after modifying your code all was working again for me. Unfortunatly your plugin kinda lack of apply_filters so i had no other way to make it work. Would it be possibile for you to fix it in the next release?

Thank you for your amazing plugin!
