//dd($request->input('email'));
$rules = array(
'email' =>'required',
'password' => 'required'
);
$validator = Validator::make($inputs, $rules);
if ($validator->fails()){
$messages = $validator->messages();
return redirect('login')
->withErrors($validator)
->withInput($request->except('password'));
} else {
if (auth()->attempt($inputs)) {
$is_admin = DB::table('users')
->where('email', $request->input('email'))
->first();
if ($is_admin->is_admin == 1) {
return redirect('/company_details');
} elseif ($is_admin->is_admin == 2) {
return redirect('dashboard');
