formigniter에서 데이터베이스 업데이트

Question

양식 제출시 데이터베이스에서 내 값을 업데이트하는 데 문제가 있습니다. E에서 정의되지 않은 메서드 Model_setting :: updateTheme()에 전화 : XAMPP \ \ htdocs를 \ CodeIgniter의-테마 \ 관리 \ 컨트롤러 \ 설정 \ setting.php에 나는 CodeIgniter는 내가 오류 치명적인 오류가 발생하고 2.20

사용 8 행

내가 보관하려고하는 것은 한 번 폼에 테마를 선택하면 설정 테이블 값이 업데이트되는 위치에 게시됩니다. 양식 제출시 변경되지 않습니다. 자동로드 된 form_validation lib 및 form helper가 있습니다.

class Model_setting extends CI_Model { 

    public function updateTheme() { 
     $this->db->select('*'); 
     $this->db->where('group', 'config'); 
     $this->db->where('key', 'config_template'); 
     $this->db->where('value', $this->input->post('config_template')); // Need to update theme row 
     $query = $this->db->update('setting');

     $this->model_setting->updateTheme(); 

     if(null !==($this->input->post('config_template'))) {

컨트롤러 : 사후 요청이있는 경우 업데이트가있을 경우

function index() { 
    $this->load->model('setting/model_setting'); //load model 
    if($this->input->post(null)){ //detect if form is submitted 
     if(null !==($this->input->post('config_template'))) { 
      $data['config_template'] = $this->input->post('config_template'); 
     } else { 
      $data['config_template'] = $this->theme->get('value'); // Auto loaded Library Theme 
     } 
     if($this->form_validation->run()) { 
      $this->model_setting->updateTheme(); 
     } 
     redirect('setting/store'); 
    }else{       // load view only 
     $data['templates'] = array(); 
     $directories = glob(DIR_CATALOG . 'views/theme/*', GLOB_ONLYDIR); 
     foreach ($directories as $directory) { 
      $data['templates'][] = basename($directory); 
     } 

     $this->form_validation->set_rules('config_template', '', 'callback_validate'); 
     $this->lang->load('setting/setting', 'english'); 

     $data['breadcrumbs'] = array(); 
     $data['breadcrumbs'][] = array(
      'text' => $this->lang->line('text_home'), 
      'href' => site_url('common/dashboard') 
     ); 
     $data['breadcrumbs'][] = array(
      'text' => $this->lang->line('heading_title'), 
      'href' => site_url('setting/setting') 
     ); 

     $data['action'] = site_url('setting/setting'); 
     $data['title'] = "Settings"; 
     $data['entry_template'] = $this->lang->line('entry_template'); 
     $data['header'] = $this->header($data); 
     $data['footer'] = $this->footer($data); 
     $this->load->view('setting/setting', $data); 
    } 
} 

먼저 확인해야 리디렉션하면 양식이 표시됩니다.

모델

<?php 

class Model_setting extends CI_Model { 

    public function update_theme() { 
     $this->db->where('key', 'config_template'); 
     $this->db->set('value', $this->input->post('config_template')); 
     $this->db->update('setting'); 
    } 
} 

먼저 몇 가지 기본적인 CI를 읽어야

public function index() { 
     //$this->load->model('setting/model_setting'); 

     $data['templates'] = array(); 

     $directories = glob(DIR_CATALOG . 'views/theme/*', GLOB_ONLYDIR); 

     foreach ($directories as $directory) { 
      $data['templates'][] = basename($directory); 
     } 

     $this->form_validation->set_rules('config_template', '', 'callback_validate'); 

     if($this->form_validation->run() == true) { 

      $this->load->model('setting/model_setting'); 

      if($this->model_setting->update_theme()) { 
       $data['config_template'] = $this->input->post('config_template'); 
      } else { 
       $data['config_template'] = $this->input->get('config_template'); 
      } 

      redirect('setting/store'); 

     } else { 

      $this->lang->load('setting/setting', 'english'); 

      $data['breadcrumbs'] = array(); 

      $data['breadcrumbs'][] = array(
       'text' => $this->lang->line('text_home'), 
       'href' => site_url('common/dashboard') 
      ); 

      $data['breadcrumbs'][] = array(
       'text' => $this->lang->line('heading_title'), 
       'href' => site_url('setting/setting') 
      ); 

      $data['action'] = site_url('setting/setting'); 

      $data['title'] = "Settings"; 

      $data['entry_template'] = $this->lang->line('entry_template'); 

      $data['header'] = $this->header($data); 
      $data['footer'] = $this->footer($data); 

      $this->load->view('setting/setting', $data); 
     } 

    }
