This is My Controller Function:-

public function register(){
        $title['pageTitle'] = 'Register Page';
        $this->load->library('form_validation');
        $this->load->model('User_model');
        $this->form_validation->set_error_delimiters('<div class = "error">','</div>');
        $this->form_validation->set_rules('firstname','First Name','trim|required|alpha|min_length[3]|max_length[30]');
        $this->form_validation->set_rules('lastname','Last Name','trim|required|alpha|min_length[3]|max_length[30]');
        $this->form_validation->set_rules('email','Email','required|valid_email|is_unique[users.email]');
        $this->form_validation->set_rules('password','Password','trim|required|md5');
        $this->form_validation->set_rules('cpassword','Confirm Password','trim|required|md5|matches[password]');
        if($this->form_validation->run() == false){
                echo validation_errors();
        }else {
                $data['userdata'] = $this->User_model->addUser();
             }
    }




This is My Model funtion :-

public function addUser(){
        $data = array(
                        'firstname'     =>  $this->input->post('firstname'),
                        'lastname'      =>  $this->input->post('lastname'),
                        'email'         =>  $this->input->post('email'),
                        'password'      =>  $this->input->post('password'),
                    );
        $q = $this->db->insert($this->tablename,$data);
        return $result = $q->result_array();
    }

This is My View(Popup):-
<div class="modal fade login_form" id="signin_model" tabindex="-1" role="dialog" aria-labelledby="exampleModalLabel">
    <div class="modal-dialog" role="document">
        <div class="modal-content pdng_mdls">
            <div class="modal-header model_hdngs">
                <a href="#" class="close close_button" data-dismiss="modal" aria-label="Close"><i class="fa fa-times" aria-hidden="true"></i></a>
                <h4 class="modal-title" id="exampleModalLabel"></h4>
            </div>
            <div class="modal-body">
        <div class="mdl_hdrs">
         <?php echo form_label('Create Your Account', 'createyouraccount'); ?>
        </div>
        <?php
             $attributes = array('name' => 'myform','id'=>'reg_form');
             echo form_open('',$attributes); ?>
          <div class="row">
            <div class="col-sm-6">
             <?php echo form_label('First Name:', 'firstname'); ?>
             <?php echo form_input(array('id' => 'firstname','class'=>'inpt_bhg cracnt','name' => 'firstname','placeholder'=>'First Name'));?>
             <span class="text-danger"><?php echo form_error('firstname'); ?></span>
            </div>
            <div class="col-sm-6">
             <?php echo form_label('Last Name:', 'lastname'); ?>
              <?php echo form_input(array('id' => 'lastname','class'=>'inpt_bhg cracnt','name' => 'lastname','placeholder'=>'Last Name'));?>
              <span class="text-danger"><?php echo form_error('lastname'); ?></span>
            </div>
            <div class="col-sm-12">
              <?php echo form_label('Email:', 'email'); ?>
              <?php echo form_input(array('id' => 'email','class'=>'inpt_bhg cracnt','name' => 'email','placeholder'=>'Email Address'));?>
              <span class="text-danger"><?php echo form_error('email'); ?></span>
            </div>
            <div class="col-sm-12">
              <?php echo form_label('Password:', 'password'); ?>
              <?php echo form_password(array('id' => 'registerpassword','class'=>'inpt_bhg cracnt','name' => 'password','placeholder'=>'Password'));?>
              <span class="text-danger"><?php echo form_error('password'); ?></span>
            </div>
            <div class="col-sm-12">
              <?php echo form_label('Confirm Password:', 'password'); ?>
              <?php echo form_password(array('id' => 'registerpassword','class'=>'inpt_bhg cracnt','name' => 'cpassword','placeholder'=>'Confirm Password'));?>
              <span class="text-danger"><?php echo form_error('cpassword'); ?></span>
            </div>
          </div>
          <div class="progress model_progress_bar" id="example-progress-bar-hierarchy-container">

          </div>
          <div class="ps_str">Password Strength</div>
          <span id = "example-getting-started-text"></span>
          <div class="final_sbmt_btns">
            <?php echo form_submit('submit', 'Create Account','class="finl_sbmt_btns"');?>
          </div>
        </form>
        <div class="go_backs"><a href="javascript:void(0);">Go Back</a></div>
      </div>
        </div>
    </div>
</div>

And This is my AJAX :-
<script type="text/javascript">
$(document).ready(function() {   
   $('#reg_form').submit(function(){
    $.ajax({
    type: "POST",
    url: BASE_URL + "User_Controller/register/",    
    data: $("#reg_form").serialize(),
    success: function(res){
        alert(res);

        }
    });
  });
});
</script>
