Route and controller not working properly in Laravel 5.2 - laravel-5

Question

I am working in a classroom project in Laravel. When I insert data that time my another route not working. but when I changed route to reverse that time my another route works and first one not work.
Here is my route:
Route::get('/class',[
'uses'=> 'classroom#getclass',
'as'=>'class',]);
another one:
Route::post('/class', [
'uses' => 'classroom#showclass',
'as' => 'classdata,]);
and i also give the controller:
public function getclass(Request $request)
{
if (Input::has('post_comment'))
{
$status=Input::get('post_comment');
$commentBox=Input::get('comment_text');
$selectedStatus=Status::find($status);
$selectedStatus->comments()->create([
'comment_text'=>$commentBox,
'user_id'=>Auth::user()->id,
'status_id'=>$status
]);
Flash::message('Your comments has been posted');
return redirect(route('class'));
}
if(Input::has('status-text'))
{
$text=e(Input::get('status-text'));
$rules = [
'status_text'=>'required|string',
];
$validator = Validator::make($request->all(), $rules);
if(Input::hasFile('status_image_upload'))
{
$rules['status_image_upload'] = 'image';
$validator = Validator::make($request->all(), $rules);
if($validator->fails())
{
$image = $request->file('status_image_upload');
$imageName = str_random(8).'_'.$image->getClientOriginalName();
$image->move('status_images', $imageName);
$userStatus = new Status();
$userStatus -> status_text = $text;
$userStatus -> image_url = $imageName;
$userStatus -> type = 1;
$userStatus -> users_id = Auth::user()->id;
$userStatus -> save();
Flash::success('Your status has been posted');
return redirect(route('class'));
}
}
else if ($validator->fails())
{
$userStatus = new Status();
$userStatus -> status_text = $text;
$userStatus -> video_url = $request['video_url'];
$userStatus -> type = 2;
$userStatus -> users_id = Auth::user()->id;
$userStatus -> save();
Flash::success('Your status has been posted');
return redirect(route('class'));
}
another one:
public function showclass(Request $request)
{
$randomnumber = rand(50001,1000000);
$classrooms = new Classrooms();
$classrooms->class_name = $request['class_name'];
$classrooms->subject_name = $request['subject_name'];
$classrooms->section = $request['section'];
$classrooms->class_code = $randomnumber;
$classrooms -> user_id = Auth::user()->id;
$classrooms -> save();
return view('class', array('class' => Auth::user()) );
}
Where is my problem? I tried it many different way. But not fixed the problem.
