分页CI合并表

Question

我需要在联合桌上的CI分页方面提供帮助。

以下代码无效。所有信息都显示在单个页面中，但链接（$ this-＆gt; pagination-＆gt; create_links（）;）显示正确分页时应具有的正确页面数量。每当我点击下一页或其他页面时，它都会显示相同的结果。任何使这项工作成功的建议。谢谢。

首先，你完全搞砸了MVC的设计理念。尽管如此，这是一个广泛的主题，这不是你所要求的，所以我将集中精力解决你的问题。

public function last_three_months(){
$this->load->model('mymodel');
$this->load->database();
$this->load->library('btree');
$this->load->library('session');
$this->load->library('string');
$this->load->library("Pagination");

    $per_page = 10;
    $page = $this->uri->segment(3, 1);
    $limit = ($page-1)* $per_page;




    if(date("l",strtotime('now')) == "Monday")
        $isMonday = strtotime('now');
    else
        $isMonday = strtotime('last Monday');
    $min = $isMonday - 7257600; // 7257600 = 12 weeks
    $max = strtotime('now');
    //echo(date("l d M Y",$duration));


//Change the following query to COUNT(id) or something like that.
    $sql = 'SELECT DISTINCT pi.ID PLAN_ID, pi.IMP_PLAN_DATE DUE_DATE, pi.CHANGE_TICKET CHANGE_TICKET,
