thinkphp5基础

【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

<?phpnamespace app\index\controller;u think\config;class demo extends ba{    // 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        $config = config("paginate.type");        dump(config("?paginate111"));//boolean fal        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// 配置文件的使用return [    "cyy" => [        'cyy' => 1,            ]];

路由的使用

自定义路由

application/index/controller/video.php

<?phpnamespace app\index\controller;class video extends controller {    // 自定义路由    public function getvideo() {        $id = input("param.id");        // /d/file/titlepic/getvideo        //  => 域名/video/2        dump($id);    }}

application/route.php

<?php// +----------------------------------------------------------------------// | thinkphp [ we can do it just think ]// +----------------------------------------------------------------------// | copyright (c) 2006~2016 /d/file/titlepic/www.thinkphp.cn all rights rerved.// +----------------------------------------------------------------------// | licend ( http://www.apache.org/licens/licen-2.0 )// +----------------------------------------------------------------------// | author: liu21st <liu21st@gmail.com>// +----------------------------------------------------------------------u think\route;// 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+']],]);

控制器的使用

application/index/controller/demo.php

<?phpnamespace app\index\controller;u think\config;u think\request;class demo extends ba{    /**     * 初始化     * @auth   cyy     * @return [type] [description]     */    public function _initialize() {        dump("这是initialize");    }    public function test() {        // 数组转json格式返回        return json(["as" => 1, "cyy" => "test"]);    }    public function hello() {        var_dump(input("param."));        return "index-index-hello";    }    // 控制器-跳转    public function abc() {        $id = input("param.id", 0, "intval");        if($id == 1) {            $this->success("操作成功", "admin/index/index");        }elif($id == 2) {            $this->error("操作失败");        }        }    // 控制器-重定向    public function ef() {        $this->redirect("hello", ["id" => 1, "ms" => 123]);        //redirect("https://baidu.com");    }    // 控制器-请求    public function requestdata() {        $request =  request::instance();        //访问/d/file/titlepic/requestdata        dump(request()->ispost());//boolean fal        dump(input("?get.ids"));//boolean true        dump(request()->has("ids", "get"));//boolean true    }}

application/index/controller/ba.php

<?phpnamespace app\index\controller;u think\controller;class ba extends controller {    /**     * 空操作     * @auth   singwa     * @param  [type] $name [description]     * @return [type]       [description]     */    // 控制器-空操作    public func全国一卷数学答案tion _empty($name) {        // todo        return $name;    }}

数据库配置与model层数据操作

application/databa.php

<?php// +----------------------------------------------------------------------// | thinkphp [ we can do it just think ]// +----------------------------------------------------------------------// | copyright (c) 2006~2016 /d/file/titlepic/www.thinkphp.cn all rights rerved.// +----------------------------------------------------------------------// | licend ( http://www.apache.org/licens/licen-2.0 )// +----------------------------------------------------------------------// | author: liu21st <liu21st@gmail.com>// +----------------------------------------------------------------------return [    // 数据库类型    'type'            => 'mysql',    // 服务器地址    'hostname'        => 'localhost',    // 数据库名    'databa'        => 'test',    // 用户名    'urname'        => 'root',    // 密码    'password'        => '123456',    // 端口    'hostport'        => '3306',    // 连接dsn    'dsn'             => '',    // 数据库连接参数    'params'          => [],    // 数据库编码默认采用utf8    'chart'         => 'utf8',    // 数据库表前缀    'prefix'          => 'test_',    // 数据库调试模式    'debug'           => true,    // 数据库部署方式:0 集中式(单一服务器),1 分布式(主从服务器)    'deploy'          => 0,    // 数据库读写是否分离 主从式有效    'rw_parate'     => fal,    // 读写分离后 主服务器数量    'master_num'      => 1,    // 指定从服务器序号    'slave_no'        => '',    // 是否严格检查字段是否存在    'fields_strict'   => true,    // 数据集返回类型    'resultt_type'  => 'array',    // 自动写入时间戳字段    'auto_timestamp'  => fal,    // 时间字段取出后的默认时间格式       'datetime_format'  => fal,    // 是否需要进行sql性能分析    'sql_explain'     => fal,];

模型
application/common/model/ba.php

<?phpnamespace app\common\model;u think\model;class ba extends model{    protected $autowritetimestamp = true;    //protected $createtime = 'create_a_time';    /**     * 新增逻辑     * @auth  singwa     * @param array  $data [description]     * @return  int     */    public function add($data = []) {        if(empty($data) || !is_array($data)) {            return fal;        }        $this->allowfield(true)->save($data);        return $this->id;    }}

application/common/model/video.php

<?phpnamespace app\common\model;class video extends ba{    /**     * 定义一个关联 1-1     * @auth   singwa     * @return [type] [description]     */    public function videofile() {        return $this->hasone("videofile"); // video_id    }}
