How to add post data into already exist array in Laravel - laravel-5

Question

I have a contact form. There is some code from the confirm page and the final page with the 'your message has been sent' message controller code.
I need to add a couple of post data to the 'confirm' page.
How do I recieve those post data and add them to the $data array at the complete function?
/*
* confirm page
*/
public function confirm(Request $request)
{
$rules = [];
$this->validate($request, $rules);
$data = $request->all();
$request->session()->put('data',$data);
dd($request);
return view('mail.confirm', compact("data"));
}
/*
*　final page (your message has been sent page)
*/
public function complete(Request $request)
{
$data = $request->session()->pull('data');
$token = array_shift($data);
$Contact = Contact::create($data);
$data = session()->regenerateToken();
return view('mail.complete');
}

To add post data, you can retrieve from the $request variable using:
$request->all();
For your case:
public function complete(Request $request)
{
$data = $request->session()->pull('data');
$token = array_shift($data);
$data = array_merge($data, $request->all());
$Contact = Contact::create($data);
$data = session()->regenerateToken();
return view('mail.complete');
}
