Selection of countries by select from the database

Hello.

I'm just starting to learn CodeIgniter.

I have a question.
The database created a table of countries and fields.

PHP Code:

CREATE TABLE IF NOT EXISTS `country` (
  `country_id` int(11) NOT NULL,
  `name` varchar(128) NOT NULL,
  `iso_code_2` varchar(2) NOT NULL,
  `iso_code_3` varchar(3) NOT NULL,
  `address_format` text NOT NULL,
  `postcode_required` tinyint(1) NOT NULL,
  `status` tinyint(1) NOT NULL DEFAULT '1'
) ENGINE=MyISAM AUTO_INCREMENT=258 DEFAULT CHARSET=utf8; 


At the moment I have on the page when registering the user, I need to write the country in the text field.

PHP Code:

<input class="form-control required" name="country" type="text" placeholder="<?php echo translate('country');?>" data-toggle="tooltip" title="<?php echo translate('country');?>"> 


I want the country instead of the field:

Select the select from the bats from the table country.
How to do it?

Help me please.

A model:

Code:

<?php

defined('BASEPATH') OR exit('No direct script access allowed');

class Countries_model extends CI_Model {

    public function dropdown($enabled_only = true) {

        $enabled_only = !empty($enabled_only);

        $this->db
            ->select('iso_code_2', 'name')
            ->from('countries');

        if ($enabled_only) {

            $this->db
                ->where('status >', 0);
        }

        $rows = $this->db
            ->order_by('name', 'asc')
            ->get()
            ->result_array();

        if (empty($rows)) {
            // Just in case, ensuring array type.
            $rows = array();
        }

        return array_column($rows, 'name', 'iso_code_2');
    }
}

In a controller:

Code:

$this->load->helper('form');
$this->load->model('countries_model');

$country_list = $this->countries_model->dropdown();
// Pass $country_list variable to the view.

In the corresponding view:

Code:

echo form_dropdown('country_code', $country_list, '' /* set_value('country_code', $country_code) */ , 'id="country_code" class="form-control required"');

This example could be simplified, bu I did not do it intentionally, for better readability.

@ivantcholakov

1. Created the model /application/models/Countries_model.php
Added your code.

2. In the file Home / application /controllers/Home.php added your code.

In file
/application/views/front/user/register/index.php
How to insert your code?

echo form_dropdown ('country_code', $ country_list, '' / * set_value ('country_code', $ country_code) * /, 'id = "country_code" class = "form-control required"');


If I have a choice form select.

Help me please.
