Bonjour. Je n'arrive pas à faire afficher ma requête. Quelque chose dans la class qui ne fonctionne pas.

Salut,

quand tu fais ceci :

Code:

SPDO::getInstance()

tu renvoies une instance de SPDO mais pas de PDO, en conséquence pas de ->prepare() sur l'instance SPDO.

Reprends ton code autrement de manière à renvoyer du PDO

J'ai remplacé SPDO par PDO.
Même problème.

Euh, tu lis ce que t'écris ?

Code:

$stmt = PDO::getInstance()

Où t'as dans ton code PDO ?
Tu aurais dû faire comme ça :

Code:

$stmt = $this->PDOInstance->prepare($sql);
