Answer 1

// To create a new user in controller
public function create()
{
// user/createOrUpdate.blade.php view
return View::make('user.createOrUpdate');
}
// To update an existing user
public function edit($id)
{
$user = User::find($id);
// user/createOrUpdate.blade.php view
return View::make('user.createOrUpdate')->with('user', $user);
}
Add/edit in view with the help of user model
#if(isset($user))
{{ Form::model($user, ['route' => ['updateroute', $user->id], 'method' => 'patch']) }}
#else
{{ Form::open(['route' => 'createroute']) }}
#endif
{{ Form::text('fieldname1', Input::old('fieldname1')) }}
{{ Form::text('fieldname2', Input::old('fieldname2')) }}
{{ Form::submit('Save', ['name' => 'submit']) }}
{{ Form::close() }}

<form action="{{ ( $view_type == 'edit' ? route('example', $id) : route('control.mentors.store')) }}" role="form" method="post" name="frmDetail">
