laravel中fill()方法的使用

1.个人理解fill方法就是用来过滤前端传输过来的与模型中对应的多余字段

下面我们来看看简单的使用

1.1数据表

1 CREATE TABLE `user` (
2   `id` int(5) NOT NULL AUTO_INCREMENT,
3   `username` varchar(15) CHARACTER SET utf8mb4 COLLATE utf8mb4_0900_ai_ci DEFAULT NULL,
4   `password` varchar(999) CHARACTER SET utf8mb4 COLLATE utf8mb4_0900_ai_ci DEFAULT NULL,
5   PRIMARY KEY (`id`)
6 ) ENGINE=InnoDB AUTO_INCREMENT=68 DEFAULT CHARSET=utf8mb4 COLLATE=utf8mb4_0900_ai_ci;

数据库信息

1.2模板路由

Route::get('/', function () {
    return view('index');
});

1.3控制器

Route::post('demo','DemoController@demo');

2.视图层代码（这里注意第三个字段测试使用）

 1 <!doctype html>
 2 <html lang="en">
 3 <head>
 4     <meta charset="UTF-8">
 5     <meta name="viewport"
 6           content="width=device-width, user-scalable=no, initial-scale=1.0, maximum-scale=1.0, minimum-scale=1.0">
 7     <meta http-equiv="X-UA-Compatible" content="ie=edge">
 8     <title>个人测试网页</title>
 9 
10 </head>
11 <body>
12 <form action="demo"  method="post">
13 {{csrf_field()}}
14         USERNAME:<input type="text" name="username" ><br>
15         PASSWORD:<input type="password" name="password"><br>
16         测试:<input type="text" name="test"><br>
17     <input type="submit" value="提交">
18 
19 </form>
20 </body>
21 </html>

3.控制器层代码

 1 <?php
 2 
 3 namespace AppHttpControllers;
 4 
 5 use AppModelsUser;
 6 use IlluminateHttpRequest;
 7 
 8 class DemoController extends Controller
 9 {
10     //
11     public function demo(Request $request)
12     {
13         $data=new User();
14        $data->fill($request->except('_token'));
15      $data->username=$request->username;
16      $data->password=$request->password;
17     return $data->save();
18 
19         //User::create(['username'=>'sda','password'=>'sad']);
20     }
21 }
