                   <div id="addanother">
                        <?php echo $this->ckeditor->editor("textheading_lead[]",""); ?>
                        <br>
                        <div class="form-group">
                            <label for="sel1">小見出し</label>
                            <select class="form-control" name="subheading[]">
                                <option value="">監修 one</option>
                                <option value="">監修 two</option>
                                <option value="">監修 three</option>
                                <option value="">監修 four</option>
                            </select>
                        </div>
                        <input type="text" class="form-control" name="subheading_text[]">
                    </div>
                    <div id="addnewdiv"></div>
                    <a href="" class="btn btn-info addfields" >+</a>

$('.addfields').on('click', addfields);
function addfields(e) {
  var new_input = $('#addanother').html();
  var aaa = new_input + '<br>';
  $('#addnewdiv').append(new_input);
  e.preventDefault();
}

* Controller * 

public function add_special(){
        $this->load->library('ckeditor');
        $this->load->library('ckfinder');
        $this->ckeditor->basePath = base_url().'asset/ckeditor/';

        $this->ckeditor->config['language'] = 'en';
        $this->ckeditor->config['width'] = '730px';
        $this->ckeditor->config['height'] = '300px';

        $this->ckfinder->SetupCKEditor($this->ckeditor,'../../asset/ckfinder/'); 

        $this->load->view('common/header');
        $this->load->view('admin/special/add_special');
        $this->load->view('common/footer');
    }

Solution

  • Unfortunately ckeditor plugin used to create dynamic id for editor panel. While appending div, plugin finds duplicate editor instances with same id textheading_lead[] and it was throwing error in your case. Here i made some alterations and will work for you.

        </div>

    </div>      
</form>

</div>
<script type="text/javascript">
    $('.addfields').on('click', addfields);
    var i=0;
    function addfields(e) {
      e.preventDefault();
      var copy = $('#addanother').clone();

      var oneplus=i+1;

      $(copy).find('div#cke_textheading_lead\\[0\\]').remove();
      $(copy).find('script').remove();
      $(copy).find('textarea[name=textheading_lead\\[0\\]]').attr('name', 'textheading_lead['+oneplus+']');

      $('#addnewdiv').append($(copy).html()+ '<br>');
      CKEDITOR.replace('textheading_lead['+oneplus+']');
      i++;  

    }
</script>
</body>
</html>

    You can receive response in your controller like $_POST["textheading_lead"] or Codeigniter post method and as usual it gets as an array.
