Codeigniter form validation

Ane mau tanya gan ane ngikut di tutorial <a href='http://mbahcoding.com/tutorial/php/codeigniter/codeigniter-ajax-crud-modal-server-side-validation.html'>http://mbahcoding.com/tutorial/php/codeigniter/codeigniter-ajax-crud-modal-server-side-validation.html</a> disitu ane nemu validasi yg agak beda yg sama ane gunain biasanya scriptnya kaya dibawah

 private function _validate()
    {
        $data = array();
        $data['error_string'] = array();
        $data['inputerror'] = array();
        $data['status'] = TRUE;

        if($this->input->post('firstName') == '')
        {
            $data['inputerror'][] = 'firstName';
            $data['error_string'][] = 'First name is required';
            $data['status'] = FALSE;
        }

        if($this->input->post('lastName') == '')
        {
            $data['inputerror'][] = 'lastName';
            $data['error_string'][] = 'Last name is required';
            $data['status'] = FALSE;
        }

        if($data['status'] === FALSE)
        {
            echo json_encode($data);
            exit();
        }
    }

kalo ane mau coba implement pake form validation yg biasa bagaimana ya, seperti script dibawah, karena script diataskan cuma ketika fieldnya kosong aja.. ane mau coba implement min_length atau max_length misalkan pake script diatas

$this->form_validation->set_rules('username', 'Username', 'trim|required|min_length[5]|max_length[12]');
$this->form_validation->set_rules('password', 'Password', 'trim|required|min_length[8]');
$this->form_validation->set_rules('passconf', 'Password Confirmation', 'trim|required|matches[password]');

private function _validate()
{
// load library form validation
$this->load->helper(array('form', 'url'));
$this->load->library('form_validation');

// set rule form input set_rules('input name', 'title / caption info, 'syarat / option validasi')
$this->form_validation->set_rules('username', 'Username', 'trim|required|min_length[5]|max_length[12]');
$this->form_validation->set_rules('password', 'Password', 'trim|required|min_length[8]');
$this->form_validation->set_rules('passconf', 'Password Confirmation', 'trim|required|matches[password]');

if ($this->form_validation->run() == FALSE)
{
   // misal jika validasi gagal, redirect ke form untuk melengkapi syarat input
}
else
{
   // misal jika validasi berhasil, input data ke db dan redirect page ke dashboard
}

}

cara diatas bisa diaplikasikan ke yg gak reload page ga ya mas? saya coba cara ini sih.. tapi masih eror

private function _validate2()
		{
			$data = array(

						array(
								'field' => 'show_title',
				                'label' => 'Show Title',
				                'rules' => 'required|trim|min_length[5]|max_length[12]'
						)
					);

			if($this->form_validation->run()==FALSE)
			{
				echo json_encode($data);
				exit();
			}
		}

sebelum execute validation run, coba tambahin set_rule

$this->form_validation->set_rules($data);

bisa aja di post tanpa reload page, pake ajax coba liat di http://stackoverflow.com/questions/37185883/do-form-validation-with-jquery-ajax-in-codeigniter

saya coba cara seperti ini mas, sudah berhasil sih //Controller

public function ajax_add()
		{
			$this->form_validation->set_rules('firstname', 'First Name', 'required|min_length[5]|max_length[12]');
			$this->form_validation->set_rules('lastname', 'Last Name', 'required');

			if($this->form_validation->run()==FALSE)
			{
				echo json_encode(array('st'=>0, 'msg' => validation_errors()));

			}else{

				echo json_encode(array('st'=>0, 'msg' => 'Successfully Submiited'));
			}
		}

tapi saya mau coba pake form_error bukan validation_error kira2 bagaimana ya, jadi messagenya per text field ini script add form saya

<div id="validation-error"></div>

        <form action="#" id="form" method="post" enctype="multipart/form-data">
            <div class="row">
                <div class="col-md-8">
                    <div class="form-body">

                        <div class="form-group">
                            <label>First Name</label>
                            <input type="text" class="form-control" name="firstname" value="<?php echo set_value('firstname'); ?>">
                            <span class="help-block"></span>
                        </div>

                        <div class="form-group">
                            <label>Last Name</label>
                            <input type="text" class="form-control" name="lastname" value="<?php echo set_value('lastname'); ?>">
                            <span class="help-block"></span>
                        </div>

                    </div>

                    <div class="form-group">
                        <button type="button" id="btnSave" onclick="insert()" class="btn btn-success">
                            <span class="glyphicon glyphicon-floppy-disk"></span> Simpan
                        </button>

                    </div>

    $('#btnSave').attr('disabled',true); //set button disable
    var url;

    url = "<?php echo site_url('validate/ajax_add')?>";
    // ajax adding data to database
    tinyMCE.triggerSave();
    var formData = new FormData($('#form')[0]);
    $.ajax({
        url : url,
        type: "POST",
        data: formData,
        contentType: false,

        dataType: "JSON",
        success: function(data)
        {

            if(data.st == 0)
            {
             $('#validation-error').html(data.msg).css('color','red');
            }

            if(data.st == 1)
            {
              $('#validation-error').html(data.msg);
            }
            $('#btnSave').text('save'); //change button text
            $('#btnSave').attr('disabled',false); //set button enable

        },
        error: function (jqXHR, textStatus, errorThrown)
        {
            alert('Error adding / update data');
            $('#btnSave').text('save'); //change button text
            $('#btnSave').attr('disabled',false); //set button enable

        }
    });
}
    </script>
