Send parameter from one route to another

Question

I want to send a variable from one route to another, to display this variable in the view, use example:

public function create(ExamRequest $request)
{
    Exam::create( $request->all() );
    $message = 'A avaliação "'.$request->input('name').'" foi registrada!';
    return redirect()->route('exams')->withMessage($message);
}

The route exams in my case calls a view, and I try to display the parameter in the same way:

<div class="row text-success text-center">
    {{ isset($message) ? $message : '' }}
</div>

But nothing is ever displayed, as I can send a parameter to another route?

PS: I know with view works, example view('exams')->withMessage($message);, but in case does not change the browser link, and I want that link to stick.

Answer 1

return redirect()->route('exams')->with(['message' => $message]);

If it is configured in the Routes file an action for the link exams, will work.

<div class="row text-success text-center">
    {!! (Session::has('message')) ? Session::get('message') : '' !!}
</div>

Answer 2

There’s nothing wrong with your redirect.

In fact, the method with¹ stores the value temporarily passed in the session, until it is accessed. This is called "Session Flash" in most frameworks.

_{1 - Both in the normal call of the method and in the magic call of the method with the data is sent to the flash}

To access the value, you would have to do so in the view:

 {!! session('message') !!}
