• Laravel之简单的学生信息管理平台


    laravel框架写的简易版的学生信息管理平台,贯穿了laravel的控制器、视图、模板、模型、中间件、路由规则的使用。

    页面是使用BootStrap前端框架搭建

    使用laravel实现了增删改查的功能。

    //这是路由文件的关键代码
    Route::group(['middleware' => ['web']], function () {
        Route::get('student/index',['uses'=>'StudentController@index']);
        Route::any('student/create',['uses'=>'StudentController@create']);
        Route::post('student/save',['uses'=>'StudentController@save']);
        Route::any('student/update/{id}',['uses'=>'StudentController@update']);
        Route::any('student/detail/{id}',['uses'=>'StudentController@detail']);
        Route::any('student/delete/{id}',['uses'=>'StudentController@delete']);
    });
    
    //控制器文件的关键代码,增删改查
    class StudentController extends  Controller{
        //学生列表
        public function  index(){
            $students = Student::paginate(20);
    
            //dd($students);
            return view('student.index',[
                'students'=>$students,
            ]);
        }
    
        //新增页面
        public function create(Request $request){
            $student = new Student();
    
            if($request->isMethod('POST')){
    
                //1.控制器验证
