這篇文章主要介紹了Laravel框架實(shí)現(xiàn)簡(jiǎn)單的學(xué)生信息管理平臺(tái),結(jié)合具體案例形式較為詳細(xì)的分析了基于Laravel框架的學(xué)生信息管理平臺(tái)路由與控制器相關(guān)操作技巧,并附帶完整源碼供讀者下載參考,需要的朋友可以參考下

本文實(shí)例講述了Laravel框架實(shí)現(xiàn)簡(jiǎn)單的學(xué)生信息管理平臺(tái)。分享給大家供大家參考，具體如下：

laravel框架寫的簡(jiǎn)易版的學(xué)生信息管理平臺(tái)，貫穿了laravel的控制器、視圖、模板、模型、中間件、路由規(guī)則的使用。

頁(yè)面是使用BootStrap前端框架搭建

使用laravel實(shí)現(xiàn)了增刪改查的功能。

//這是路由文件的關(guān)鍵代碼
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']);
});

//控制器文件的關(guān)鍵代碼,增刪改查
class StudentController extends Controller{
  //學(xué)生列表
  public function index(){
    $students = Student::paginate(20);
    //dd($students);
    return view('student.index',[
      'students'=>$students,
    ]);
  }
  //新增頁(yè)面
  public function create(Request $request){
    $student = new Student();
    if($request->isMethod('POST')){
      //1.控制器驗(yàn)證
