【thinkphp5框架的目录结构，以及使用框架model 、controler、view的使用，以及错误调试和日志记录】

ThinkPHP5 在php5.5版本以上”No input file specified“问题解决：

　　public/.htaccess文件中的

　　RewriteRule ^(.*)$ index.php/$1 [QSA,PT,L]

　　在默认情况下会导致No input file specified.

　　修改成

　　RewriteRule ^(.*)$ index.php [L,E=PATH_INFO:$1]

　　问题解决

配置文件的使用

application/index.controller/Demo.php

<?php
namespace appindexcontroller;
use thinkConfig;

class Demo extends Base{
    // 配置文件的使用
    public function config() {
         默认一页显示15条
        $config = Config::get("paginate");
        dump($config);15

        $config = config("paginate.type");
        dump(config("?paginate"));boolean true

        );
        dump(config("?paginate111"));boolean false

        dump(Config::has("paginate"));boolean true

        dump(config("cyy"));
         array (size=1)
          // cyy' => int 1
  
        dump(config("redis.host"));string '127.0.0.1'
    }
}

application/extra/redis.php

<?php
 配置文件的使用
return [
    "host" => "127.0.0.1",
];

application/index/config/php

<?php

 [
    "cyy" => [
        'cyy' => 1,1)">
        
    ]
];

路由的使用

自定义路由

application/index/controller/Video.php

<?php
namespace appindexcontroller;

class Video  Controller {

     自定义路由
     getVideo() {
        $id = input("param.id");

         http://phptest.com/index/video/getVideo?id=2
        //  => 域名/video/2
        dump($id);
    }
}

application/route.php

// +----------------------------------------------------------------------
 thinkRoute;

 自定义路由 域名/video/2
// Route::rule("video/:id","index/Video/getVideo");
//Route::get("video/:id","index/Video/getVideo");// 定义Get请求路由
//Route::post("video/:id","index/Video/getVideo");// 定义Post请求路由

// 组合写法
Route::get([
    'video/:id' => ["index/Video/getVideo",[],['id' => 'd+']],1)">
]);

控制器的使用

application/index/controller/Demo.php

<? thinkConfig;
 thinkRequest;

/**
     * 初始化
     * @auth   cyy
     * @return [type] [description]
     */
     _initialize() {
        dump("这是initialize");
    }
     test() {
         数组转json格式返回
        return json(["as" => 1,"cyy" => "test"]);
    }

     hello() {
        var_dump(input("param."return "index-index-hello";
    }

     控制器-跳转
     abc() {
        $id = input("param.id","intval");
        if($id == 1) {
            $this->success("操作成功","admin/index/index");
        }elseif($id == 2$this->error("操作失败");
        }    

    }

     控制器-重定向
     ef() {
        $this->redirect("hello",["id" => 1,"ms" => 123]);
        redirect("https://baidu.com");
    }

     控制器-请求
     requestData() {
        $request =  Request::instance();
        访问http://phptest.com/index/demo/requestData?ids=2
        dump(request()->isPost());boolean false
        dump(input("?get.ids"));boolean true
        dump(request()->has("ids","get"));    }
}

application/index/controller/Base.php

<? thinkController;
class Base *
     * 空操作
     * @auth   singwa
     * @param  [type] $name [description]
     * @return [type]       [description]
      控制器-空操作
    function _empty($name) {
         todo
        return ;
    }
}

数据库配置与model层数据操作

application/database.php

模型
application/common/model/Base.php

<?php
namespace appcommonmodel;
 thinkModel;
 Model{

    protected $autoWriteTimestamp = true;
    protected $createTime = 'create_a_time';
    *
     * 新增逻辑
     * @auth  singwa
     * @param array  $data [description]
     * @return  int
     function add($data = []) {
        if(empty($data) || !is_array($data)) {
            return false;
        }

        $this->allowField(true)->save($this->id;
    }
}

application/common/model/Video.php

<?php
namespace appcommonmodel;

 Base{

    *
     * 定义一个关联 1-1
     * @auth   singwa
     * @return [type] [description]
      videoFile() {
        $this->hasOne("VideoFile");  video_id
    }
}

application/common/model/VideoFile.php

<?class VideoFile  Base{
    
}

application/index/controller/Video.php

<? thinkDb;
use appcommonmodelVideo as VideoModel;
 Base {

     数据库query查询
    function mysql() {
        $video = Db::query("select * from test_video where id=2"$video);
    }

     模型的使用
     model() {
         获取id为2的数据
        $video = VideoModel::get(2dump($video);

        $video = new VideoModel();
        $video->title = "cyy-test";
        $video->description = "cyy-test-description1";
        dump($video->save());//int 1 插入数据保存成功

         [
            "title" => "cyy-test3",1)">
        ];
        dump($video->save($data));//dump($video->save());//int 1 插入数据保存成功
 增
     add() {
        $video = model("Video");

         [
            "title" => "cyy-test6","mpt" => 1,1)">
        ];
        
        $id = $video->add($id);string '6' (length=1)
 查
     select() {
        $conditon = [
            "status" => 1,1)">
        ];

        $videos = model("Video")->where($conditon)->select();
        $videos = model("Video")
            ->where($conditon)
            ->limit(1)
            ->order("id","desc")
            ->select();
        dump($videos 改
     update() {
        $updataData = [
            "title" => "cyy你好鸭"
        ];

        $whereCondition = [
            "id" => 1,1)">$res = model("Video")->allowField(true)->save($updataData,$whereCondition);
        //echo model("Video")->getLastSql(); //作用非常重要
        //dump($res);

        model("Video")->where($whereCondition)
            ->update($updataDataecho model("Video")->getLastSql();UPDATE `test_video` SET `title`='cyy你好鸭' WHERE `id` = 1    
 删
     delete() {

         这种场景是 真正的删除
        $res = model("Video")->where("id",">",18)->delete();
        echo model("Video")->getLastSql();
        dump($res);*/

         在实际工作当中 我们的删除一般不直接删除， 所以一般假删除
        //  修改status => -1
        model("Video")->where(["id" => 6])
            ->update(["status" => -1UPDATE `test_video` SET `status`=-1 WHERE `id` = 6
    }
一对一关联
     correlation() {
        $video = model("Video")->find(1halt($video->videoFile->file);    
        //dump(VideoModel::hasWhere("videoFile",["video_id" => 1])->find());//string 'file1' (length=5)
        
        // 1vs1 插入
        model("Video")->title = "1VS1-add-test";
        model("Video")->image = "1vs1.gif";

        model("VideoFile")->file = "1vs1.flv";
        model("VideoFile")->status = 1;
         model("Video")->VideoFile = model("VideoFile");

         dump(model("Video")->together("VideoFile")->save());

         // 1vs1 更新操作
         );
         $video->title = "1vs1-update-test";
         $video->videoFile->file = "1vs1-update.mp4";
         dump($video->together("videoFile")->save());

         // 1 vs N  查询
         //dump(model("Video")->videoFile()->where("video_id",1)->select());
         //dump(VideoModel::hasWhere('videoFile',["video_id" => 1])->select());    
    }
}

视图层

?application/index/controller/Video.php

<? demo() {

        $video = model("Video")->where(["id" => 1])->find();
        $videos = model("Video")->where("id",1)->select();
        
         halt($video->update_time);//halt=dump+exit
        // halt($video->update_time);
        // halt($video->toArray());

        $this->fetch("",1)"> [
            "name" => "cyy","names" => ["name" => "hello,cyy!"],"video" => $video,"videos" => $videos,"id" => input("param.id")
        ]);
