Tp5 学习

确认Tp5连接数据库

<?php
namespace appindexcontroller;
use thinkController;
use thinkDb;
class Index  extends  Controller
{
    public function index()
    {
        $res =Db::connect();
        dump($res);
    }
}

出现相关信息，连接成功。

tp5 阅读了增加 

use thinkController;
use 	hinkRequest;
use thinkDb;
use thinkLoader;

 public function  ceshi(){

        $name="小兰";

        $data=Db::name("ce")->where("name",$name)->field("click_num")->select();
         $click_num=$data[0]["click_num"]; //12
        $click_nums=$click_num+1;
        $data=Db::name("ce")->where("name",$name)->setField("click_num","$click_nums");
        //dump($data);die;
        if($data ===1){
            return "true";
        }else{
            return "false";
        }


    }

也可以用TP5 自带的自增+1 方法

 $datas =Db::name("tonghua")->where("id", $id)->setInc("click_num"); //点击率加1

// score 字段加 1
Db::table("think_user")->where("id", 1)->setInc("score");
// score 字段加 5
Db::table("think_user")->where("id", 1)->setInc("score", 5);
// score 字段减 1
Db::table("think_user")->where("id", 1)->setDec("score");
// score 字段减 5
Db::table("think_user")->where("id", 1)->setDec("score", 5);

TP5 简单的过滤设置

tp5 二表关联查询 

    

tp5 去除index.php  修改.htaccess 

<IfModule mod_rewrite.c>
Options +FollowSymlinks -Multiviews
RewriteEngine on
RewriteCond %{REQUEST_FILENAME} !-d
RewriteCond %{REQUEST_FILENAME} !-f
RewriteRule ^(.*)$ index.php [L,E=PATH_INFO:$1]
</IfModule>
