This is Controller code of contact us page.
public function store(Request $request)
{
Contact::create([
'name' => $request->name,
'email' => $request->email,
'subject' => $request->subject,
'message' => $request->message,
]);
\Session::flash('flash_message','successfully saved.');
return redirect()->back();
}
Problem is i have a one page theme so i redirect same page after contact us details fill. But contact details here stay , not blank....what is it solution?

Answer 1

don't use return back try by using return view
return view('viewName');

Answer 2

Because your browser will do "back" when you use your code:
return redirect()->back();
Change to use this:
return redirect()->route('your_back_route_name');
I think that will work as reload page.
When it's not work, i think it is about your browser auto fill.
So, set you input value is empty when load.
<input value="" />
