当我在视图中选择链接时，codeigniter 分页链接不起作用？

Question

当我单击视图中的链接时，它显示找不到页面。任何人都可以帮助我吗？还告诉我为什么这些链接不起作用？数据显示没问题。但是转到表格其他页面的链接不起作用。当我单击找不到“1,2,3”页面时。它仍然在同一个地方..我猜它会被发布或遇到问题？。

这是我的控制器。

<?PHP
/**
* 
*/
class Search extends MY_Controller
{

    public  function index ()

    {   
        if  ($this->form_validation->run('search') == FALSE)

       {


            $this->load->model('City');
           $deals=$this->City->default_city();
           foreach ($deals as $key) 
           {

                   $city_id=$key->city_id;
                   $city_name=$key->city_name;
                   $city_status=$key->city_status;

           } 



        }

        else

       {


            $city_name=$this->input->post('city_name');
            $this->load->model('City');
            $city_id=$this->City->other_city($city_name);


            foreach ($city_id as $row)

            {
                    $city_id= $row->city_id;
                    $city_name=$row->city_name;
                    $city_status=$row->city_status;


            }
        }   

            $deal_name=$this->input->post('deal_name');
            $data['city_id']=$city_id;
            $data['city_name']=$city_name;
            $data['city_status']=$city_status;
            $this->load->model('Deals');
            $total_deals=$this->Deals->total_deals();
            $config=[
            'base_url' => base_url().'Search',
            'per_page' => 3,
            'total_rows' => $this->Deals->number_rows($deal_name,$city_id,$city_status),
            'uri_segment'=> 2,
            ];
            $this->pagination->initialize($config);

            $user_search=$this->Deals->user_search($deal_name,$city_id,$city_status,$config['per_page'],$this->uri->segment(2));
            $data['links']=$this->pagination->create_links();
            $data['deals']=$user_search;

            $data['total_deals']=$total_deals;
            $total_categories=$this->Deals->total_categories();
            $data['total_categories']=$total_categories;
            for($i=1;$i<=$total_categories;$i++)

            {
                $deals_by_categories[]=$this->Deals->deals_by_categories($i);
            }
            $category_name=$this->Deals->categories();
            //$category_name = json_decode(json_encode($category_name), true);
            $data['category_name']=$category_name;
            $data['deals_by_categories']=$deals_by_categories;
            $this->load->view('page-search',$data);








    }
}
?>

这是我的模型函数

public function user_search($deal_name,$city_id,$city_status,$limit,$offset)  

    {  

           $query= $this->db->select('merchants.merchant_logo,deals.deal_title,deals.deal_description,deals.start_date,deals.end_date,deal_id')
           ->from('deals')
           ->join('merchants_branches', 'deals.branch_id=merchants_branches.branch_id', 'inner')
           ->join('merchants', 'merchants_branches.merchant_id=merchants.merchant_id', 'inner')
           ->join('cities','cities.city_id=merchants_branches.city_id','inner')
           ->where('merchants_branches.city_id',$city_id)
           ->where('cities.city_status',$city_status)
           ->where('deal_status', 1)
           ->like('deals.deal_name',$deal_name)
           ->limit($limit,$offset)
           ->get();
           return $query->result();

    }

     public function number_rows($deal_name,$city_id,$city_status)  

    {  

           $query= $this->db->select('merchants.merchant_logo,deals.deal_title,deals.deal_description,deals.start_date,deals.end_date,deal_id')
           ->from('deals')
           ->join('merchants_branches', 'deals.branch_id=merchants_branches.branch_id', 'inner')
           ->join('merchants', 'merchants_branches.merchant_id=merchants.merchant_id', 'inner')
           ->join('cities','cities.city_id=merchants_branches.city_id','inner')
           ->where('merchants_branches.city_id',$city_id)
           ->where('cities.city_status',$city_status)
           ->where('deal_status', 1)
           ->like('deals.deal_name',$deal_name)
           ->get();
           return $query->num_rows();

    }

这是我的看法

<?php 
                    if(count($deals)):
                    foreach ($deals as $deals) : 
                    date_default_timezone_set("Asia/Dubai");
                    $date=date('Y-m-d H:i:s');
                    $enddate=$deals->end_date;

                    $date = new DateTime($date);

                    $enddate = new DateTime($enddate);

// The diff-methods returns a new DateInterval-object...
                    $diff = $date->diff($enddate);
                    if($date<$enddate):
// Call the format method on the DateInterval-object


                 ?>

                        <a class="col-md-4 model-1" href="<?php echo base_url(); ?>DealDescription/<?php echo $deals->deal_id  ?>/<?php echo $city_status?>">

                        </a>


                    <?php else: header('location:'.base_url().'SearchError'); endif; endforeach;?>
                         <?php else: header('location:'.base_url().'SearchError');

                    endif; 
                    ?>
                    <?php echo $links; ?>

Answer 1

由于 CodeIgniter 的工作方式，以及控制器的索引方法中确实不能包含 URI 段的事实，您需要将搜索移至不同的方法。如果您执行以下操作，这很容易：

public function index()
{
    $this->results();
}

public function results( $page = 1 )
{
     // your code
}

现在请注意，您现在实际上在 URI 段 3 中有一个页面变量。这很重要，因为 CodeIgniter 将根据配置查找该页面：

$config['uri_segment'] = 3; // You can't use 2!

此外，在 CodeIgniter 中，使用 site_url 而不是 base_url 来分页 base_url 很重要：

$config['base_url'] = site_url('search/results'); // Do not uppercase "search"

此外，如果您希望页面具有自然的用户体验，您应该使用页码：

$config['use_page_numbers'] = TRUE;

采用这种方法，您仍然需要确定您的查询偏移量是多少，因为它显然不是页码：

$offset = ( $page * $config['per_page'] ) - $config['per_page'];

另外，请务必阅读用户指南的分页页面，因为它非常有帮助：https://www.codeigniter.com/userguide3/libraries/pagination.html

这应该让您立即分页。
