How to navigate back with form input?

Question

In my view1 I have a post form, with the action to a post route.

The post function in the controller saves the request's data to a session and redirects to view2.

In that view I want to have a link to navigate back to view1 but with the form filled out. For validation purposes, I already have old() in place.

I expected the follow to work, but the function does not exists on the route helper:

← Back

Here is the controller:

public function view1()
    {
        return view('view1');
    }

    public function post_create(CreateRequest $request)
    {
        $request->session()->put('data', $request->all());

        return redirect()->route('view2');
    }

    public function view2()
    {
        return view('view2', [
            'data' => session('data'),
        ]);
    }

If you have stored that data in session so why are you not retrieving data from session.

Like this

session("key") ? session("key") : old("key") ? old("key") : ""

Or

if(session("key")) {
    return session("key");
} elseif (old("key")) {
    return old("key");
} else {
    return "";
}

It will check if session has data so it get data from session and check in elseif part old field has data or not and else do nothing
