实例化页面代码

1.时间代码：{$vo.createtime|toDate=###,‘Y-m-d H:i:s‘}

2.连接：{:U(‘Pro/arr‘)}  如：<form action="{:U(‘Pro/arr‘)}" name="form" method="post">

php页面中的连接

URL(‘Service-Pro/arr‘)如：$url = URL(‘Service-Pro/arr‘).‘&p=‘;   // 5.定义连接

 

查询语句$where[‘status‘]=‘1‘;

$where[‘name‘]=‘百度‘;$list = $m->where($where)->select();还有其他几中1.$where = ‘and status =1‘;2.$where[‘status‘]=‘1‘;3.$list = $m->where(‘status=1‘)->select(); 4.$where[‘title‘] = array(‘like‘,‘%‘.$title.‘%‘);

 

自己写分页代码

public function arr(){        $m = M(‘problem‘);          //0.基本条件        $pagesize = ‘1‘;        $p = $_GET[‘p‘];                 if(empty($_GET[‘title‘])){            $title = ‘‘;            }else{            $title = $_GET[‘title‘];                    }        $where[‘title‘] = array(‘like‘,‘%‘.$title.‘%‘);   // 1.查询条件        $where[‘status‘] = ‘1‘;                $totalNum=$m->where($where)->count();   // 2.总几条数据        $totalpage = intval($totalNum/$pagesize);   // 3.计算分页[共几页]        $totalp = $totalNum%$pagesize;        if($totalp !=0){            $totalpage +=1;            }                $nowpage = $p;                          // 4. 翻页分4个节点【当前页，上一页，下一页，尾页】        if($p<=1){            $nowpage = ‘1‘;        }        $nowsize = $nowpage*$pagesize-$pagesize;    // [当前条数]                        $firstpage = 1;        $prevpage = $nowpage-1;  //[上一页]        if($prevpage<=$nowpage){            $prevpage = $nowpage;            }        $nextpage = $nowpage+1;   //[下一页]        if($nextpage>=$totalpage){            $nextpage = $totalpage;            }        $lastpage = $totalpage;  //[尾页]                $url = URL(‘Service-Pro/arr‘).‘&title=‘.$title.‘&p=‘;   // 5.定义连接        $page = ‘<a class="a1">共‘.$totalNum.‘条 当前‘.$nowpage.‘/‘.$totalpage.‘页</a>‘;        $page .= ‘<a href="http://www.mamicode.com/‘.$url.$firstpage.‘">第一页</a>‘;        $page .= ‘<a href="http://www.mamicode.com/‘.$url.$prevpage.‘">上一页</a>‘;        $page .= ‘<a href="http://www.mamicode.com/‘.$url.$nextpage.‘">下一页</a>‘;        $page .= ‘<a href="http://www.mamicode.com/‘.$url.$lastpage.‘">尾页</a>‘;                $list = $m->where($where)->limit($nowsize,$pagesize)->order(‘createtime desc‘)->select();        $this->assign(‘ser_title‘,$title);        $this->assign(‘page‘,$page);        $this->assign(‘list‘,$list);        $this->display();    }
