Hello, please tell me how to get a parameter from an array.
Here's what I have in the request

. And here's what I can get so far..

And I would like only the 'titre' field.

$val=$request->request->get('new_liseuse', ['titre']); // 
        dump($val);

Thank you.

Answer 1

$request->request->get('new_liseuse')['titre']
to make it clear:

$array = $request->request->get('new_liseuse');
var_dump($array['titre']);
