分布类异常

goyuquan

分页类连接部分不好使，只显示前4个连接，不管在哪页，都是1是当前页，但内容可以连接过去，

前第一页按不了，因为1页始终是当页页状态。
不知道怎么回事

控制器

已解决，重新梳理了一下程序重写了一遍

现在代码上
控制器

PHP复制代码

<?php
class Content extends CI_Controller {
 
        public function __construct()
        {
                parent::__construct();
                $this->load->model('content_model');
                $this->load->model('page_model');//分页模型
                $this->load->library('pagination');//分页
        }
       
        public function index($page = 0)
        {
                $config['base_url'] = 'http://localhost/ci/index.php/content/page/';//分页参数，路由配合
                $num = $this->page_model->get_pages('content');
                $config['total_rows'] = $num;
                $config['per_page'] = 3;
                $config['uri_segment'] = '3';
                $this->pagination->initialize($config);
               
                $pageNum=$this->uri->segment(3)?$this->uri->segment(3):1;
                if($pageNum==1){
                        $offset=0;
                }else{
                        $offset=$config['per_page']*($pageNum-1)+1;
                }//以上分页参数
               
                $data['title'] = 'Content archive';
                $data['content'] = $this->page_model->paging('content',$config['per_page'],$pageNum);
               
                $this->load->view('templates/header', $data);
                $this->load->view('content/index');
                $this->load->view('templates/footer');
        }
}

视图

PHP复制代码

<?php foreach ($content as $content_item): ?>
 
    <h2><?php echo $content_item['title'] ?></h2>
    <div id="main">
        <?php echo $content_item['text'] ?>

路由

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

$route['default_controller'] = 'pages/view';
$route['404_override'] = '';

$route['content'] = 'content';
$route['content/add'] = 'content/add';
$route['content/update'] = 'content/update';
$route['content/update/(:any)'] = 'content/update/$1';
$route['content/page/(:any)'] = 'content/index/$1';
$route['content/page'] = 'content/index';
$route['content/update_content/(:any)'] = 'content/update_content/$1';
$route['content/del/(:any)'] = 'content/del/$1';
$route['content/(:any)'] = 'content/view/$1';

$route['upload'] = 'upload';

$route['login/login_array'] = 'login/login_array';

$route['login'] = 'login';

$route['upload/do_upload'] = 'upload/do_upload';

$route['(:any)'] = 'pages/view/$1';

再自忆建个表，加上视图出出现的几个字段就行了

我记得我做分页的时候，不管怎样都不行，然后换了一个新版本的ci就行了
