Cant write data in database using codeigniter - sql

Question

I have a controller, model and view file. I am trying to write data to database using the form on view file. I am trying to validate the post data using a mix of Codeigniter Validation library and some methods defined by. This validation is being done in Controller. Then I am trying to pass data array to the model. In the model I am trying to read the data array and build a query to insert data in database.
The problem is that no data is being written in the database.
I dont see any visible errors in the browser. I have been stuck on this for some time now. Any help is appreciated. Thanks in advance.
Controller
function add_customer() {
$this->load->model('Customer_Model');
$data['title'] = "Add New Customer";
$this->load->view('templates/header' , $data);
$this->load->view('dashboard/add_customer' , $data);
$this->load->view('templates/footer' , $data);
if($this->input->post())
{
$this->form_validation->set_rules('name', 'Name', 'trim|required');
$this->form_validation->set_rules('email', 'Email', 'trim|required|valid_email|customer_email_exists');
$this->form_validation->set_rules('mobile', 'Mobile', 'trim|required|customer_mobile_exists');
$this->form_validation->set_rules('address', 'Address', 'trim|required');

$customer_data = array(
'name' => $this->validation->name,
'email' => $this->validation->email,
'mobile' => $this->validation->mobile,
'address' => $this->validation->address

$this->Customer_Model->add_customer($customer_data);

Hmm! I think in this code part you should get post data from input, not from validation
if ($this->form_validation->run()){
$customer_data = array(
'name' => $this->input->post('name'),
'email' => $this->input->post('email'),
'mobile' => $this->input->post('mobile'),
'address' => $this->input->post('address'),
);
$this->Customer_Model->add_customer($customer_data);
}else{
}
