Answer 1

This question was already answered here
$this->input->post('img') in model won't work to retrieve the image information. Because the images are stored in $_FILES not in $_POST. So you need to use the upload library in codeignitor like below.
Also, make sure that your form contains the enctype="multipart/form-data" attr and your column type is blob in the database.

Answer 2

i will give you an example.This is the controller section.
public function add()
{
if (empty($_FILES['image']['name']))
{$this->session->set_flashdata('yes', 'Please Upload an image');
redirect($_SERVER['HTTP_REFERER']);
}
else
{
$target_dir = "images/products/";
$target_file = $target_dir . time().basename($_FILES["image"]["name"]);
$imageFileType = pathinfo($target_file,PATHINFO_EXTENSION);
$imgName = time().basename($_FILES["image"]["name"]);
move_uploaded_file($_FILES["image"]["tmp_name"],$target_file);
$this->adminmodel->addproducts($imgName);
}
}
Model section
public function addproducts($imgName)
{
$data = array(
'name' => $this->input->post('name'),
'category' => $this->input->post('category'),
'image' => $imgName
);
$this->db->insert('products', $data);
$this->session->set_flashdata('yes', 'Product added successfully');
redirect('admin/products/productlist');
}
View Section(Form)
form role="form" action="admin/products/add" method="post" enctype="multipart/form-data" id="contact-form">
Your Form should contain enctype="multipart/form-data"
