Bonjour,

Voila je rencontre un petit problème avec mon code.

Ce que je fais

class Comments{

private $pdo;
private $default = array(
    'username_error' => "Vous n'avez pas rentré de pseudo",
    'email_error' => "Votre email n'est pas valide",
    'content_error' => "Vous n'avez pas mis de message",
    'parent_error' => "Vous essazer de répondre à un commentaire qui n'existe pas"

        SELECT *
        FROM comments2

            AND ref = :ref
        ORDER BY created DESC");
    $q->execute(['ref' => $ref, 'ref_id' => $ref_id]);
    $comments = $q->fetchAll();
    $this->count = count($comments);

    // Filtrage des réponses
    $replies  = [];
    foreach($comments as $k => $comment){

        }
    }

        }else{
