Redirection avec la fonction header
Bonsoir,
j'ai écrit ce script qui me permet de récupérer les données de connexion de l'utilisateur depuis la base, les stocker dans une variable de session puis de le rediriger sur une autre page.
Malheureusement, et je ne comprends pas pourquoi, ce script refuse de s'exécuter correctement!!
Voici les messages d'erreur :
