How to insert upload images in opencart? - php

Question

I am beginner to OpenCart eshop. I am trying to create a custom form depending on printing services. I need to insert an uploaded image into MySQL and show it at OpenCart's admin section. How to validate <input type='file'> file type input in OpenCart? In pure PHP there is $_FILES[][] array applicable but how to access submitted files in OpenCart? Please, help me solve it.
if (isset($this->error['file'])) {
$this->data['error_file'] = $this->error['file'];
} else {
$this->data['error_file'] = '';
}
