Probléme d'envoie de liens de telechargement crypté

par **moogli** » 20 sept. 2011, 12:55

salut,

je vois ligne 340 : $body = str_replace($tags,$vals,$email_body);

Mais pas $email_body avant !

affiche le $body avant avant envoi des mails pour vérifier ce qu'il y a dedans.
sait tu comment s'articule le code exactement ?

pourquoi les @devant les fonctions send_mail() ?
les mails sont ils aux format au format html ?

est tu l'auteur du code ? si ce n'est pas le cas a tu demandé à l'auteur ?

Bonjour,

J'ai fait une recherche avec des mots de ton mail ("lien" et "achat") et je ne les ai pas trouvé dans ton code. J'ai arrêté la, après une lecture en diagonale de ton code.

Bonjour la communauté ,

J'éspére un peu de vos compétences , car je tourne en ron , j'ai un script , de téléchargement de fichiers via l'envoie d'un mail , contenant le liens de téléchargement , après paiement par paypal .
Jusqu'au choix des fichiers à telecharge et le paiement tout est ok , je recois bien la notification de paiement par paypal .
et le problème se situe dans mon mail , qui ne contient pas le lien de téléchargement des produits payés ...

je recois le message suivant sans le liens :

-------User Email----------
Bonjour Test User
Merci de votre achat .
Voici le lien de telechargement - ( et pas de liens )
Ce lien reste actif pendant 24 hours.
Cordialement

ci joint mon script Php:

/* Global defines */
$time = time();
