我想在codeigniter中使用分页进行简单的搜索...

我真的不知道怎么做..

我的模特

public function testSearch()
{
    $this->db->like('Profile_for', 'Myself');
    $query = $this->db->get('users');
    return $query->result();
}

我的控制器

public function searcher()
{
  $config['base_url']='http://localhost/index.php/controller/searcher';
    $config['total_rows'] = $this->Model->testSearch()->num_rows();
    $config['per_page'] = 5;
    $config['num_links'] = 2;   

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

    $data['records'] = $this->Model->testSearch($config['per_page'], $this->uri->segment(3));

    $this->load->view('pagination', $data);
}

我认为我的控制器代码错了......

请帮帮我吧......

提前致谢.....

1.在Config文件夹下打开routes.php

2.现在在controllers文件夹下创建一个名为pagination.php的文件并粘贴以下代码：

<?php if ( ! defined('BASEPATH')) exit('No direct script access allowed');

class Pagination extends CI_Controller 
{
    public function __construct() {
        parent:: __construct();

        $this->load->helper("url");
        $this->load->model("Countries_Model");
        $this->load->library("pagination");
    }

    public function index() {
        $config["base_url"] = base_url() . "pagination";
        $config["total_rows"] = $this->Countries_Model->record_count();
        $config["per_page"] = 10;
        $config["uri_segment"] = 2;

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

        $page = ($this->uri->segment(2))? $this->uri->segment(2) : 0;
        $data["results"] = $this->Countries_Model
            ->get_countries($config["per_page"], $page);
        $data["links"] = $this->pagination->create_links();

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

3.在models文件夹下创建一个名为countries_model.php的文件并粘贴以下代码：

<?php if ( ! defined('BASEPATH')) exit('No direct script access allowed');

class Countries_Model extends CI_Model
{
    public function __construct() {
        parent::__construct();
    }

    public function record_count() {
        return $this->db->count_all("tblcountries");
    }

    public function get_countries($limit, $start) {
        $this->db->limit($limit, $start);
        $query = $this->db->get("tblcountries");

        if ($query->num_rows() > 0) {
            foreach ($query->result() as $row) {
                $data[] = $row;
            }
            return $data;
        }
        return false;
   }
}

4.最后，在views文件夹下创建一个名为pagination.php的文件并粘贴以下代码

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml">
<head>
<meta charset="utf-8">
<title>Pagination with CodeIgniter</title>
</head>
<body>
<div id="container">
    <h1 style="text-align:center">Page Navigation in PHP</h1>
    <table width="400" border="1" align="center">
        <tr>
            <td width="100" bgcolor="#CCCCCC"><p>Country ID</p></td>
            <td width="300" bgcolor="#CCCCCC">Country</td>
        </tr>
        <h1 style="text-align:center">Countries</h1>
            <div id="body">

        <?php
        foreach($results as $data) {
        ?>
        <tr>
            <td><?php echo $data->CountryID ?></td>
            <td><?php echo $data->Country ?></td>
        </tr>
        <?php
        }
        ?>
    </table>
    <div style="text-align:center"><?php echo $links; ?></div>
</div>
</div>
</body>
</html>

这是代码概念与您的代码相同。我希望这对您有所帮助很多谢谢
