Question

Codeigniter分页对我不起作用。它显示页码和前5个搜索结果，但当我点击页面'2'时，它会加载'search_nok'视图，并显示消息“请选择您的选项”。您可以查看下面的代码并帮我找出错误。 这是我的控制器：

     public function search($offset = 0) {
            $limit = 5;

            $this->load->library('form_validation');
            $this->load->model('model_x');

            $this->form_validation->set_rules('country', 'Country','required');

           if($this->form_validation->run()) {
            $country = $this->input->post('country');

            $this->load->library('pagination');

$config['base_url'] = 'http://localhost/abc/cont/search/'; //where 'http://localhost/abc' is my base url
$config['total_rows'] = 14;
$config['per_page'] = 5; 

$data['pagination'] = $this->pagination->initialize($config);

            if ($this->model_x->did_search($country, $limit, $offset)){

            $data["results"] = $this->model_x->did_search($country, $limit, $offset); 
            $this->load->view("search_ok",$data);           
            }          
            }
            else
            {
            $data['message'] = 'Please select your options.';   

            $this->load->view("search_nok",$data);          
             }              
       }

以下是我的观点：

   <?php

echo $this->pagination->create_links();

foreach($results as $row){                  
$country = $row['country'];                     
$city = $row['city'];
?>                      
<table>
<tr>
    <td >        
    <b><?php echo $country; ?></b>    
    </td>
    <td>    
    <b><?php echo $city; ?></b>    
    </td>
</tr>
</table>
<?php }?>

我认为你对分页感到困惑。首先，技术上所有的分页内容：

<?php
$this->load->library('pagination');

$config['base_url'] = 'http://localhost/abc/cont/search/'; //where 'http://localhost/abc' is my base url
$config['total_rows'] = 14;
$config['per_page'] = 5;

应该在您的控制器中，其次，您实际上应该限制模型中的结果，因为您还没有显示您的模型我会想出一个示例

$this->db->limit ($limit $offset //these will be defined in your controller)
$data = $this->db->get('whatever_table')->whatever_result_type.
return $data

您应该在控制器中定义$limit并将其作为函数接受的参数传递给您的模型函数

控制器还应该有$ offset和$ limit defined

 public function search($offset = 0) {

$limit = 5;

当你打电话给模特时，一定要通过

$this->model_x->did_search($country, $limit, $offset);

然后而不仅仅是$this->pagination->initialize($config);

这样做（仍然在你的控制器中记住）：

$data['pagination'] = $this->pagination->initialize($config);

然后在视图中的任何地方回应分页

Codeigniter分页对第二页不起作用
