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.
