업데이트 쿼리가 codeigniter에서 작동하지 않습니까?

나는 데이터베이스에서이 레코드가 업데이트되지 않습니다 실행합니다. 1 씩 증가하지만 값은 동일하게 유지됩니다. 에코 된 SQL 문이 $this->db->last_query()에서 올 바릅니다. MySQL 워크 벤치에 직접 복사하고 붙여 넣으면 변경 사항이 적용되었습니다.

액티브 레코드를 사용하지 않으려 고 시도했습니다.

Answer 1

$this->db->trans_complete();과 관련이 있습니다. 사용자가 잘못된 암호를 입력하면 즉시 값을 반환하므로 트랜잭션이 완료되지 않고 변경 내용이 커밋되지 않습니다.

잘못된 암호를 확인하기 위해 대신 플래그를 설정해야했습니다. $this->db->trans_complete(); 후 다음

private $wrong_password = FALSE; 

if ($login_attempts >= 3) 
       { 
        //Enable CAPTCHA 
        $random_number = substr(number_format(time() * rand(),0,'',''),0,6); 
        $vals = array(
        'word'   => $random_number, 
        'img_path'  => './captcha/', 
        'img_url'  => base_url().'captcha/', 
        'font_path'  => './path/to/fonts/texb.ttf', 
        'img_width'  => '150', 
        'img_height' => 30, 
        'expiration' => 7200, 
        'word_length' => 8, 
        'font_size'  => 16, 
        'img_id'  => 'Imageid', 
        'pool'   => 'abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ', 

        // White background and border, black text and red grid 
        'colors'  => array(
          'background' => array(255, 255, 255), 
          'border' => array(255, 255, 255), 
          'text' => array(0, 0, 0), 
          'grid' => array(255, 40, 40) 
         ) 
        ); 

        $this->captcha = create_captcha($vals); 
        $this->session->set_userdata('captchaWord', $random_number); 
       } 

       // $data = array(
       //  'login_attempts' => 'login_attempts + 1' 
       // ); 
       // $this->db->where('username', $username); 
       // $this->db->update('company', $data); 
       $sql = "UPDATE 
          company 
         SET 
          login_attempts = login_attempts + 1 
         WHERE 
          username = ? 
         "; 
       $query = $this->db->query($sql, $username); 

       $this->wrong_password = TRUE; 

:

if ($this->db->trans_status() === FALSE) { 
     return 'Transaction failed'; 
    } else { 

     if ($this->wrong_password === TRUE) { 
      return FALSE; 
     } 
    } 

이러한 정직한 실수.
