Answer 1

ex for codeignitor
function save()
{
$feature = $this->input->post('feature');
$json = json_encode($feature);
$this->Your_model_Name->save($json);
}

Answer 2

You simply need to get the INPUTS based on the form method. Save the inputs in a variable based on form method post/get.
POST:
$features=$_POST["feature"];
GET:
$features=$_GET["feature"];
$features will be a PHP Array and you can use json_encode() to encode the PHP Array to JSON String. Like this,
$features_json=json_encode($features);
Now use this variable $features_json to save JSON String in MySQL Database.
Your JSON String after encoding will look like this: http://json-parser.com/67c07feb

Since it is an array, you need a foreach loop. your function must look like this
Controller
function save()
{
foreach($this->input->post('feature') as $f)
{
$f = trim($f);
$data = json_encode($f);
$this->YOUR_MODEL->insert_to_table($data);
}
}
Model
function insert_to_table($data)
{
$this->db->insert('table_name',$data);
}
This way, you post every input you have
hope this helps

Answer 4

controller (product)
function save() {
$features = $this->input->post('feature');
$feature_json = json_encode($features);
//send to model
$this->load->model('your_model');
$this->your_model->insert($feature_json);
}
model
function insert($feature_json) {
$data = array(
'features' => $feature_json
);
$this->db->insert($data);
}
update
Add trim and xss clean using form validation
$this->form_validation->set_rules('feature[]',"Feature", "trim|xss_clean");
