How to show validation message in controller Codeigniter

How can I use {ci_form_validation field='title' error='true'} in the controller ?

I have this code 

$this->load->library('form_validation');
$this->form_validation->set_rules('title', $this->lang->line('title'), 'trim|required|min_length[3]|xss_clean');   
$this->form_validation->set_rules('fahad', $this->lang->line('blog'), 'trim|required|min_length[20]|xss_clean'); 
$this->form_validation->set_rules('writer', $this->lang->line('writer'), 'trim|required|alpha_dash|min_length[3]|xss_clean');

I want to print error message in controller because I am using jquery.

Use this from user guide

echo form_error('field_name');

EDITED

ok try 

echo validation_errors();

this will give you every error after that you can get what you want

Actually, there is no way to do this with CodeIgniter out of the box. However, it is quite easy to extend the original form validation library.

  • create a file titled "MY_Form_validation.php" in your application/libraries folder

  • add the following code to application/libraries/MY_Form_validation.php

    class MY_Form_validation extends CI_Form_validation {

    public function __construct() {

        parent::__construct();

    }

    /**
     * Return all validation errors
     *
     * @access  public
     * @return  array
     */
    function get_all_errors() {

        $error_array = array();

        if (count($this->_error_array) > 0) {

            foreach ($this->_error_array as $k => $v) {

                $error_array[$k] = $v;

            }

            return $error_array;

        }

        return false;

    }


}

Then from your controller:

    echo "<pre>";

    print_r($this->form_validation->get_all_errors());

    echo "</pre>";
