Answer 1

You can simple can access that by using

$val = $_POST['category_images'];

Or in CI method

$val = $this->input->post('category_images');

Answer 2

Change this line :

<select name="category_images" id="combo_category">

to

<select name="category_images" id="combo_category" onchange="this.form.submit()">

Then in your controller upload_control/do_upload, you can get the selected value using :

echo $this->input->post('category_images');

For processing the uploaded file, you may use Codeigniter File Upload library.
