I have add below code in core file( catalog\controller\product\category.php ) for Refine categories images. So, It is working fine.
But, when, this same code add via vqmod (without change core file). So, It is working fine. But, if, not available Refine categories in categories page.So, Get error ( Notice: Undefined variable:.... )
ADDED code :
$image = $this->model_tool_image->resize($result['image'], $this->config->get('config_image_category_width'), $this->config->get('config_image_category_height'));
How to fix it?
Thanks.
