Les votes ne sont pas incrémenter mais la l'utilisateur est considéré comme «voté», donc l'utilisateur ne peut pas voter à nouveau une fois connecté. Ma seule préoccupation est que les votes ne comptent pas. Y a-t-il quelque chose qui ne va pas dans mes codes ou ma compréhension du nombre de votes n'est-elle pas si bonne? Je vous remercie!
quand vous dites « sans compter », qu'est-ce que vous signifie spécifiquement? Vous voulez dire que vous voulez mettre à jour un "compte" quelque part stocké dans la mémoire qui dit combien de personnes ont voté pour "cette personne" pour secrétaire, "cette personne" pour trésorier, etc? – Webeng
dans la base de données, tous les comptes de votes pour chaque candidat sont mis à 0, et si un utilisateur vote pour les candidats, je voudrais qu'il augmente. Mais ça ne s'incrémente pas. Oui, exactement ce que vous avez dit! Je pense qu'il y a quelque chose qui cloche avec mes codes sql mais c'est mon troisième essai et ça ne marche toujours pas –
@Webeng il y a quelques mises à jour dans le code! – Jeff
