Answer

I think the problem because of your blade file. you have to put the correct name for each input.

<input type="text" name="name" value="{{ $student->studname }}" class="form-control" placeholder="Name">
--------------------------
<input type="text" name="course" value="{{ $student->course }}" class="form-control" placeholder="Course">
