CodeIgniter - How to Multi Detail Form

Hi everyone. 
can I ask for help about something? I want to create a user registration form where I allow user to be able to put as many emails and phones as they want just like Google Contacts. 
I already create a form that allow users to add or remove the input fields for email and phone dynamically. but I haven't figured it out how to store the data into database.

see attachment for the image of the Form I created.

This is the customer_model.php I created to store the data into database.

Code:

<?php if ( ! defined('BASEPATH')) exit('No direct script access allowed');

class Customer_model extends CI_Model {

    protected $table = 'customer';
    protected $table_detail = 'address';
    protected $table_detail2 = 'phone';

    public $avatar;
    public $name;
    public $address = [];
    public $phone = [];

    public function __construct()
    {
        parent::__construct();

        $this->flush();
    }

    private function flush()
    {
        $this->avatar = '';
        $this->name = '';
        $this->address = [];
        $this->phone = [];
    }

    private function validate()
    {
        if (
            empty($this->avatar) ||
            empty($this->name) ||
            empty($this->address) ||
            empty($this->phone)
        ) {
            return FALSE;
        }

        return TRUE;
    }

    public function all()
    {
        $this->db->order_by('id', 'desc');

        $q = $this->db->get($this->table);

        $r = $q->result();

        foreach ($r as $key => $value) $r[$key]->address = $this->get_address($value->id);

        return $r;
    }

    public function get_address($customer_id)
    {
        $this->db->select('address.id, address_title.title, address.address');
        $this->db->join('address_title', 'address_title.id = address.title_id');
        $this->db->order_by('address.id', 'asc');

        $q = $this->db->get_where($this->table_detail, ['customer_id' => $customer_id]);

        return $q->result();
    }

    public function get_title($term = '')
    {
        $this->db->order_by('id', 'asc');

        if (! empty($term)) $this->db->like('LOWER(title)', strtolower($term), 'both');

        $q = $this->db->get('address_title');

        return $q->result();
    }

    public function get($id)
    {
        $q = $this->db->get_where($this->table, ['id' => $id]);

        return $q->num_rows() > 0 ? $q->row() : FALSE;
    }

    public function destroy($id)
    {
        return $this->db->delete($this->table, array('id' => $id));
    }

    public function store()
    {
        if (! $this->validate()) return FALSE;

        $this->db->trans_begin();

        try {
            $this->db->insert($this->table, $this);

            $id = $this->db->insert_id();

            foreach ($this->address as $key => $value) $this->address[$key]['customer_id'] = $id;

            $this->db->insert_batch($this->table_detail, $this->address);
        } catch (Exception $e) {
            return FALSE;
        }

        if ($this->db->trans_status() === FALSE)
        {
            $this->db->trans_rollback();
            return FALSE;
        } else {
            $this->db->trans_commit();
            return TRUE;
        }
    }

    public function store2()
    {
        if (! $this->validate()) return FALSE;

        $this->db->trans_begin();

        try {
            $this->db->insert($this->table, $this);

            $id = $this->db->insert_id();

            foreach ($this->phone as $key => $value) $this->phone[$key]['customer_id'] = $id;

            $this->db->insert_batch($this->table_detail2, $this->phone);
        } catch (Exception $e) {
            return FALSE;
        }

        if ($this->db->trans_status() === FALSE)
        {
            $this->db->trans_rollback();
            return FALSE;
        } else {
            $this->db->trans_commit();
            return TRUE;
        }
    }

}

this is the customer.php (Controller) I created to get the data from View and pass it to customer_model.php 

Code:

<?php if ( ! defined('BASEPATH')) exit('No direct script access allowed');

class Customer extends CI_Controller {

    public function __construct()
    {
        parent::__construct();

        $this->load->library('session');
        $this->load->helper(['form', 'url']);
        $this->load->model('customer_model', 'model', TRUE);
    }

    public function index()
    {
        $this->load->view('customer.index.php', [
            'data' => $this->model->all(),
            'notification' => $this->session->flashdata('notification')
        ]);
    }

    public function get_avatar($id)
    {
        header('Content-type : image/jpeg');

        echo $this->model->get($id)->avatar;
    }

    public function get_title()
    {
        $titles = $this->model->get_title($this->input->get('q', TRUE));

        echo json_encode((object)[
            'items' => $titles
        ]);
    }

    public function store()
    {
        $this->model->name = $this->input->post('name', TRUE);
        $this->model->avatar = file_get_contents($_FILES['userfile']['tmp_name']);
        $this->model->address = [];
        $this->model->phone = [];

        foreach ($this->input->post('title_id', TRUE) as $key => $value) $this->model->address[$key]['title_id'] = $value;
        foreach ($this->input->post('address', TRUE) as $key => $value) $this->model->address[$key]['address'] = $value;
        foreach ($this->input->post('title_id', TRUE) as $key => $value1) $this->model->phone[$key]['title_id'] = $value1;
        foreach ($this->input->post('phone', TRUE) as $key => $value1) $this->model->phone[$key]['phone'] = $value1;
        
        if ($this->model->store() === TRUE) {
            if ($this->model->store2() === TRUE) {
                $notification = '<div class="alert alert-success">Success creating customer.</div>';
            } else {
                $notification = '<div class="alert alert-danger">Failed creating customer.</div>';
            }
        } else {
            $notification = '<div class="alert alert-danger">Failed creating customer.</div>';
        }

        $this->session->set_flashdata('notification', $notification);

        redirect(site_url('/'), 'refresh');
    }

    public function delete($id)
    {
        if ($this->model->destroy($id))
        {
            $notification = '<div class="alert alert-success">Success to delete customer.</div>';
        } else {
            $notification = '<div class="alert alert-danger">Fail to delete customer.</div>';
        }

        $this->session->set_flashdata('notification', $notification);

        redirect(site_url('/'), 'refresh');
    }

You would need to use jQuery for something like that see below.
