php代码

     public function info(){
        $where[‘openid‘]=session(‘openid‘);////用户session

        $db = M("pay");//主表名
        $table ="pay";
        $table2 = "tupian";//联合查询表名
        $page_size = 5; //每页显示记录数
        import(‘ORG.Util.Page‘);// 导入分页类
        $count = count( $db -> field(‘id‘) -> where($where) -> select() );//记录总数
        $Page = new Page($count, $page_size, 5);// 实例化分页类 传入总记录数
        $show = $Page->show();// 分页显示输出
        $list = $db -> field( "$table.yin,$table.time,$table.status,$table2.cover_url,$table2.title,$table2.id" ) ->
                 join( "$table2 on $table.pid=$table2.id" ) ->
                 where( $where ) ->
                 order( "$table.id desc" ) ->
                 limit($Page->firstRow.",".$Page->listRows) ->
                 select();
        $this->assign(‘list‘,$list);// 赋值数据集
        $this->assign(‘page‘,$show);// 赋值分页输出
        $this->display(info); // 输出模板

    }
