Laravel – Session returns null

I’m using sessions for the first time in Laravel and I’m trying to do a multiple step form, so I thought using sessions would be a smart move. however the following code returns a null value, what am I doing wrong?

        $user_information = [
            "name"           => $request->name,
            "email"          => $request->email,
            "remember_token" => $request->_token,
            "password"       => bcrypt($request->password),
            "role_id"        => 3
        ];

        session('user_signup', $user_information);

        dd(session('user_signup'));

Answer

In your controller you can save variable into session like

session()->put('user_signup',$user_information);

For checking your session variable in controller

session()->has('user_signup','default value');

For deleting your session variable in controller

session()->forget('user_signup');

For checking your session variable if it exists in blade and printing it out

@if(session()->has('user_signup'))
    session()->get('user_signup')
@endif
