Question

我对搜索结果的分页无效。它显示结果，但分页使其随机。请帮我。搜索正在运行，但不能在其中应用分页，它变得越来越复杂

search_products_model

<?php
class search_products_model extends CI_Model {

    public function __construct()
        {
               parent::__construct();
        }
    public function get_results($search_term,$limit, $offset)
    {
        // Use the Active Record class for safer queries.       
         $this->db->like('name',$search_term);

        // Execute the query.
        $query = $this->db->get('tbl_products',$limit, $offset);    

         if ( $query->num_rows() > 0 )
         {
           return $query->result_array();
         }
         else
         {
    return FALSE;
         }
        // Return the results.            
    }

       function get_products_id($id)
        {
         $this->db->where('prod_id',$id);
          $query = $this->db->get('tbl_products');
           return $query->result(); 
        }         
}
?>   

controller

<?php
class search_products extends CI_Controller
{
    public function __construct()
    {
        parent::__construct();
        $this->load->helper(array('form','url'));
        $this->load->library(array('session', 'form_validation', 'email','pagination'));
        $this->load->database();
        $this->load->model('search_products_model');
    }

    function index()
    {
        $this->search_products();
        $this->load->view('search_products_view');   
    }
    function display_registration_form()
    {        
     $this->load->view('search_products_view');   
    }

     function execute_search($offset = 0) 
    {    
        $config['base_url'] = '/mehmaa/index.php/search_products/execute_search/';
        $config['total_rows'] = $this->db->count_all_results('tbl_products');
        $config['per_page'] = 6; 
         $config['next_link'] = 'Next';
        $config['prev_link'] = 'Previous';             

        $this->pagination->initialize($config);
       // Retrieve the posted search term.
       $id = $this->input->post('id');
        $search_term = $this->input->post('term');  
        // Use a model to retrieve the results.
        $data['results'] = $this->search_products_model->get_results($search_term,$config['per_page'], $offset);  

        if ( empty($data['results']) ) 
    {                       
                 $this->load->view('search_products_view');   
                 $this->session->set_flashdata('message', 'No results found');    
    }
        else{
        // Pass the results to`enter code here` the view.            
        $this->load->view('search_results',$data);          
        }
        }

Answer 1

您好在此链接中未检查搜索条件

$config['total_rows'] = $this->db->count_all_results('tbl_products');

将此行更改为

 $config['total_rows'] = $this->db->count_all_results($search_term);

并编写正确的查询

Answer 2

$config['total_rows'] = $this->db->count_all_results('tbl_products');

在这个文件中出现问题，你需要编写另一个查询，它将通过搜索收集结果而没有偏移和限制。例如

function search($text, $offset, $limits){
  //this u do search
}

function count_search($text){
   //This same logic with search but return Integer value for example
   //return $this->db->query()->num_rows();
}

搜索结果分页不正常...搜索正在工作但是分页导致codeigniter中的错误
