php - 将图像 ID 传递给 URL 段

Question

我试图单击图像上的下一个按钮，以从从数据库获取的结果中加载下一个图像，但加载了一个新页面，因此 Bootstrap 轮播无法按我需要的方式工作。

假设我有一张包含 3 张图片的相册。这些图像的图像 ID 为 - 25、34、36。当我查看包含所有图像的相册时，我可以单击图像 ID 34。当我单击下一步时，这将带我到 www.domain.com/image/34想要重定向到 www.domain.com/image/36，然后再次单击“下一步”将重定向到 www.domain.com/image/25

所以这是我到目前为止所拥有的:

Controller :

function index($image_id)
{
    // get album data                       
    $this->data['image_data'] = $this->album_model->get_album_image_data($image_id);

    $album_id = $this->data['image_data']->album_id;
    $this->data['album_images']  = $this->album_model->get_all_images($album_id);

    $data = $this->data;           

    $this->_render_page('images/image', $data);
}

查看:

foreach($album_images as $img)
{
    if($img->image_id == $this->uri->segment(2))
    {
        echo '<img src="'.$img->image_url.'" class="img-responsive img-panel" class="img-responsive" />';
    }  
}
<!-- Image nav -->
<a class="fui-arrow-left left" href="#"></a>
<a class="fui-arrow-right right" href="#"></a>

如何获取下一个和上一个 image_id？

如果我需要包含更多信息，请告诉我。

可以使用分页，首先加载分页库。$this->load->library('pagination');引用https://codeigniter.com/user_guide/libraries/pagination.html?highlight=pagination

Controller

public function index()
{
   $config['base_url'] = site_url('dashboard-clients');
   $config['total_rows'] = //total count of your image or data
   $config['per_page'] = 1;

  //show the number of pages
  $choice = $config['total_rows']/$config['per_page'];
  $config['num_link'] = round($choice);
  $this->pagination->initialize($config);
  $page = ($this->uri->segment(2)) ? $this->uri->segment(2) :0;
  $result = $this->Your_Model->get('table name',$config['per_page'], $page)
  $str_links = $this->pagination->cretae_links();
  $data['links'] = explode('&nbsp', $str_links);
  if($result != FALSE)
  {
    $data['data'] = $result;
    $this->load->view('yoyr view file', $data);
  }
}

型号

public function get($table, $limit, $start)
{
  $this->db->limit($limit, $start);
  $query = $this->db->get($table);
  if($query->num_rows() > 0)
  {
    return $query->reult();
  }
  else
    return FALSE;
}

查看

foreach($data as $img)
{
     echo '<img src="'.$img->image_url.'" class="img-responsive img-panel" class="img-responsive" />'; 
}
//create links like 1 ,2, 3,next
<div id="pagination" align="center">
     <ul class="pagination">
         <?php if (isset($links) and is_array($links)) {
              foreach ($links as $link) {
                  echo '<li>'.$link.'</li>';
               }
           }?>
     </ul>
</div>
