我的控制器：

public function search()
    {   
        $data['category_name'] = $this->model_products->dis_category();
            $this->load->view('layout/header', $data);



            $keyword = ''; // default when no term in session or POST
            if ($this->input->post('search'))
            {
                // use the term from POST and set it to session
                $keyword = $this->input->post('search');
                $this->session->set_userdata('keyword', $keyword);
            }
            elseif ($this->session->userdata('keyword'))
            {
                // if term is not in POST use existing term from session
                $keyword = $this->session->userdata('keyword');
            }

            $data['otherproduct'] = $this->model_products->other_prodects();
            $data['otherproduct2'] = $this->model_products->other_prodects2();

            //Pagination init
            $config['base_url']     = base_url().'search/';
            $config['total_rows']   = $this->model_products->num_rows($keyword);
            $config['per_page']     = 10;
            $config['uri_segment']  = 2;
            $config['num_links']    = 2;
            //custom pigination
            $config['full_tag_open'] = '<ul class="tsc_pagination tsc_paginationA tsc_paginationA01">';
            $config['full_tag_close'] = '</ul>';
            $config['prev_link'] = 'Prev';
            $config['prev_tag_open'] = '<li>';
            $config['prev_tag_close'] = '</li>';
            $config['next_link'] = 'Next';
            $config['next_tag_open'] = '<li>';
            $config['next_tag_close'] = '</li>';
            $config['cur_tag_open'] = '<li class="current"><a href="#">';
            $config['cur_tag_close'] = '</a></li>';
            $config['num_tag_open'] = '<li>';
            $config['num_tag_close'] = '</li>';

            $config['first_tag_open'] = '<li>';
            $config['first_tag_close'] = '</li>';
            $config['last_tag_open'] = '<li>';
            $config['last_tag_close'] = '</li>';

            $config['first_link'] = 'First';
            $config['last_link'] = 'Last';

            $this->pagination->initialize($config);

            $data['search'] = $this->model_products->SearchResult($config['per_page'],$this->uri->segment(2,0),$keyword);

            $this->load->vars($data);

            $this->load->view('layout/resault', $data);
            $this->load->view('layout/footer');
    }

我的模特：

function SearchResult($perPage,$uri,$keyword)
    {
        $this->db->select('*');
        $this->db->like('pro_part',$keyword);
        $this->db->or_like('pro_description',$keyword);
        $this->db->or_like('pro_name',$keyword);


        $this->db->order_by('pro_part','asc');
        $getData = $this->db->get('products', $perPage, $uri);

        return $getData->result_array();

    }


    function num_rows($keyword){

            $this->db->select('*');
            $this->db->where_in("'pro_part' like '%$keyword'");
            $this->db->or_where_in("'pro_name' like '%$keyword'");

            $query = $this->db->get('products');
            return $query->num_rows();  
        }

我的观点：

特色产品--> “session->userdata('word') ;?>”的结果

                      <?php if(count($search) > 0):?>
                          <?php foreach ($search as $row) :?>
                            <div class="span13 product">

我的问题是结果分页计数我在数据库中的所有行不受 post 方法的限制。

【问题讨论】：

有很多代码需要我们完成。从表面上看，存在一些基本错误。我认为主要的是单引号标识符而不是反引号。
现在您的问题是什么？按数字分页不起作用。对吗？你给了$config['per_page'] = 10; 但不起作用？
参考这个-> iprogrammerindia.in/…
$config['per_page'] = 10;正在工作，但结果分页计数我在数据库中的所有行不受方法 post 的限制。

【解决方案1】：

将您的模型 where_in 更改为 where ， where_in 用于数组，在您的情况下将导致 null ，因此它不使用条件

function num_rows($keyword){

            $this->db->select('*');
            $this->db->where_in("'pro_part' like '%$keyword'");
            $this->db->or_where_in("'pro_name' like '%$keyword'");

            $query = $this->db->get('products');
            return $query->num_rows();  
        }

到

function num_rows($keyword){

            $this->db->select('*');
            $this->db->where("'username' like '%$keyword%'");
            $this->db->or_where("'full_name' like '%$keyword%'");

            $query = $this->db->get('cms_users');
            //$query1 = $this->db->last_query();
            //print_r($query1);
            return $query->result_array();  
        }
