a l'intérieur il a un fichier test un fichier src et autre exemples je sais ce que j'ai lue qui faut que je prenne le fichier src et je le mais sur mon serveur et je rentre mes 2 clé api a l'intérieur mais un coup installer sa ne marche pas.

 

j'ai beaux essayer je n'arrive a rien je ne suis pas expert dans les code mais je me débrouille.

 

 

Merci a tous de m'aider

Bonjour Ricki, et bienvenue sur le forum !

 

Parmi les modes d'emploi que tu as consultés, as-tu lu Configurer l'API Facebook ?

Bonjour !

 

Oui aussi, ce n'est plus les mêmes fichiers sont différents.

 

Merci pour votre aide.

[ricki]

Bonsoir,

 

Voici le lien sur Facebook, qui dit de télécharger ça facebook/php-sdk - GitHub

 

Là je prends mon fichier src (comme ils disent) et je le renomme. Alors dans ce fichier-là, il y a un fichier facebook.php, le 2ème qui est base_facebook.php, et un fb_ca_chain_bundle.crt

 

Voici le fichier base_facebook.php
