Laravel之简单的学生信息管理平台

Posted 2020-08-15 Yxh_blogs

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
            /*$this->validate($request,[
               \'Student.name\'=>\'required|min:2|max:20\',
