HERE'S CONTROLLER:

以下是控制器：

public function search(Request $request){

    $search = $request->search;

    $students = StudentsList::where('Student_no','Like','%'.$search.'%')->first();

    return view('front.vendors.login_register')->with(compact('students'));
    }

HERE'S ROUTE:

以下是路线：

Route::get('search/studno','VendorController@search');

HERE'S BLADE FILE:

以下是刀片式服务器文件：

  <input type="text" id="vendorfname" name="Fname" 
          class="text-field" value="{{$students['Fname']}}" 
          readonly="">

I've also tried this but still same problem coming up <input type="text" id="vendorfname" name="Fname" class="text-field" value="{{ $students->Fname}}" readonly="">

我也尝试过这个方法，但还是出现了同样的问题

You use $studentsList in your blade without compact the value of $studentsList from controller.

您在刀片中使用了$StudentsList，而没有从控制器压缩$StudentsList的值。

优秀答案推荐

Because you are using compact and sometimes $students might be false. Please use with instead of compact.

因为您使用的是精简的，有时$Students可能是假的。请配合使用，而不是紧凑型。
