Codeigniter : 데이터베이스에서 여러 이미지 표시

나는 부동산 웹 사이트를 운영하고 있습니다. 각 페이지의 특정 목록에 대해 데이터베이스의 모든 이미지를 나열하려고합니다. 다음 코드를 가지고 있지만 목록의 모든 이미지를 표시하는 대신 동일한 기본 이미지를 반복합니다.Codeigniter : 데이터베이스에서 여러 이미지 표시

내가 데이터 모델에 대해 알고하지 않습니다. 여기에 게시해야합니다.

$this->db->join('images', 'images.image_id = listings.image_id', 'left');

$this->db->join('images', 'images.listing_id = listings.id');

에 당신은 이미지 테이블이 아닌 다른 방식 라운드에서 목록의 ID를 저장해야합니다 : 데이터 모델이 제대로 된 경우, 다음이 변경됩니다 라인입니다.

편집 : 데이터 모델에서 데이터베이스 구조를 의미합니다. 모든 '목록'에 대해 n 개의 이미지가있는 경우 '이미지'표에 '목록 ID'에 대한 참조를 저장해야합니다.

내 목록 모델 및 이미지 모델은 아래에 있습니다. 죄송합니다. 명확하지 않으면 codeigniter를 처음 사용했습니다. 이미지 모델 : class Image_Model extends CW_Model {\t \t protected $ table_name = 'images'; \t 보호 된 $ order_by = 'image_id'; \t 보호 된 $ primary_key = 'image_id'; \t 보호 된 $ display_val = ''; \t \t public $ defaults = array(); \t \t public $ qualifiers = array(); \t \t public $ rules = array(); \t } – user3041984

어떤 필드가 어떤 테이블에 있는지 볼 수 있도록 질문을 편집 할 수 있습니까? 최소한 '리스팅'테이블과 '이미지'테이블 –

리스팅 필드 : listing_id, account_id, status_id, feature_id, image_id, nbrhood_id, price, beds_id, convertible, baths_id, available, pet_id, sqft, type_id, description, – user3041984

이 프로젝트를 다른 사람이 수행했습니다. 어디에서 이미지 테이블에 필드를 추가합니까? 지금 CMS에서 그것은 목록에 대한 여러 이미지를 보여줍니다. 코드는 다음과 같습니다.

   <?php foreach ($images as $image): ?> 

       <li data-image-id="<?=$image -> image_id ?>" class="uploaded-image" id="image_<?=$image -> image_id ?>"> 
        <div class="sortableimagewrapper">

         <img src="<?=images_url('110x68/' . $image -> file_name) ?>" alt="" width="110px" height="68px" class="img-polaroid" /> 
         <div class="btn-group"> 
          <button class="btn <?php 
          if ($image -> image_id == $listing -> image_id) 
           echo 'btn-warning';
