Hello, I have a form with a static field "id" and 'N' number of fileds quantity[] & description[]


I'm gettin the values on my model

Code:

$data['id'] = $this->input->post('id');
$data['quantity'] = $this->input->post('quantity');
$data['description'] = $this->input->post('description');

DATABASE FIELDS:

Code:

id
quantity
description

e.g. I have an array ($data) with the following content

Code:

ID-XXX
Array ( [0] => 1 [1] => 5 )
Array ( [0] => Lock [1] => Key  )

How can I update my DB with the new information

Code:

$this->db->where("ID and Description match array information");
$this->db->update('products', $array_here);
