//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); } } }
