不管是官網還是網路上的分頁教學,你都無法使用嗎??

OK,讓我們一步一步來吧!

為了學習起見,這邊我略過model跟view層,直接在controller內做完。

 

CodeIgniter_3.0.0\application\controllers\Welcome.php


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

class Welcome extends CI_Controller {

 public function index2() {

  $fitle_ary=array('status' => '1');
  $query = $this->db->get_where('news', $fitle_ary );//
  $num_rows=$query->num_rows();//計算總數

  $page=(int)$this->uri->segment(3); // 獲取頁碼
  $page=($page=='')?1:$page;

  $config['base_url'] = site_url(strtolower(__CLASS__).'/'.__FUNCTION__); //url地址
  $config['total_rows'] = $num_rows;
  $config['per_page'] = 3; //每頁幾筆
  $config['use_page_numbers'] = TRUE; //使用頁碼方式而非偏移量傳值
  $offset = $page == false?1:($config['per_page'] * ($page - 1)); // 用頁碼計算偏移量

  $query = $this->db->get_where('news', $fitle_ary , $config['per_page'] , $offset);//
  foreach ($query->result() as $row) {
   echo $row->cont . '<br/>';
  }

  $this->load->library('pagination');
  echo $this->pagination->initialize($config)->create_links();

 }

}


 

MYSQL資料表內容

CREATE TABLE `news` (
`id` int NOT NULL AUTO_INCREMENT PRIMARY KEY,
`title` varchar(200) NOT NULL,
`cont` text NOT NULL,
`status` tinyint(1) NOT NULL
) ENGINE='MyISAM';

-- ----------------------------
-- Records of news
-- ----------------------------
INSERT INTO "news" VALUES (1, 'gerg', 'sdvsdvdv', 1);
INSERT INTO "news" VALUES (2, 'dfbfdbdfb', 'dsbdsbdb', 1);
INSERT INTO "news" VALUES (3, 'dfbdf', 'sdbdsbsdb', 1);
INSERT INTO "news" VALUES (4, 'dfbdfb', 'sdvdsvdvsdv', 1);
INSERT INTO "news" VALUES (5, 'rgerg', 'erhff', 1);
INSERT INTO "news" VALUES (6, 'mhm', 'rehhrhrherhfdfndn ', 1);

 


 

接下來打開網址:

看到了嗎??

漂亮的分頁效果,你已經完成。
