本文实例讲述了Laravel框架实现简单的学生信息管理平台。分享给大家供大家参考，具体如下：

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',
 'Student.age' =>'required|integer',
 'Student.sex' =>'required|integer',
 ],[
 'required'=>':attribute 为必填项',
 'min'=>':attribute长度不符合要求',
 'integer'=>':attribute必须为整数',
 ],[
 'Student.name'=>'姓名',
 'Student.age' =>'年龄',
 'Student.sex' =>'性别'
 ]);*/
 //2.Validator类验证
 $validator = \Validator::make($request->input(),[
 'Student.name'=>'required|min:2|max:20',
 'Student.age' =>'required|integer',
 'Student.sex' =>'required|integer',
 ],[
 'required'=>':attribute 为必填项',
 'min'=>':attribute长度不符合要求',
 'integer'=>':attribute必须为整数',
 ],[
 'Student.name'=>'姓名',
 'Student.age' =>'年龄',
 'Student.sex' =>'性别'
 ]);
 //withInput保持数据
 if($validator->fails()){
 return redirect()->back()->withErrors($validator)->withInput();
 }
 $data = $request->input('Student');
 if(Student::create($data)){
 return redirect('student/index')->with('success','添加成功');
 }else{
 return redirect()->back();
 }
 }
 return view('student.create',[
 'student'=>$student,
 ]);
 }
 //保存数据操作
 public function save(Request $request){
 $data = $request->input('Student');
 $student = new Student();
 $student->name = $data['name'];
 $student->age = $data['age'];
 $student->sex = $data['sex'];
 if($student->save()){
 return redirect('student/index');
 }else{
 return redirect()->back();
 }
 }
 //更新数据操作
 public function update(Request $request,$id){
 $student = Student::find($id);
 if($request->isMethod('POST')){
 //Validator类验证
 $validator = \Validator::make($request->input(),[
 'Student.name'=>'required|min:2|max:20',
 'Student.age' =>'required|integer',
 'Student.sex' =>'required|integer',
 ],[
 'required'=>':attribute 为必填项',
 'min'=>':attribute长度不符合要求',
 'integer'=>':attribute必须为整数',
 ],[
 'Student.name'=>'姓名',
 'Student.age' =>'年龄',
 'Student.sex' =>'性别'
 ]);
 //withInput保持数据
 if($validator->fails()){
 return redirect()->back()->withErrors($validator)->withInput();
 }
 $data = $request->input('Student');
 $student->name = $data['name'];
 $student->age = $data['age'];
 $student->sex = $data['sex'];
 if($student->save()){
 return redirect('student/index')->with('success','修改成功-'.$id);
 }
 }
 return view('student.update',[
 'student'=>$student,
 ]);
 }
 //信息详情
 public function detail($id){
 $student = Student::find($id);
 return view('student.detail',[
 'student'=>$student,
 ]);
 }
 //删除操作
 public function delete($id){
 $student = Student::find($id);
 if($student->delete()){
 return redirect('student/index')->with('success','删除成功-'.$id);
 }else{
 return redirect('student/index')->with('error','删除失败-'.$id);
 }
 }
}
