Afficher des points sur la carte
Salut à tous ! :)
Mon but est d'afficher des points sur une carte Google Maps. Ces points sont définis par leur Latitude + Longitude (stockés eux-même dans une base de données MySQL). J'ai donc trouvé ce "tuto" réalisé par Google : https://developers.google.com/maps/a.../phpsqlajax_v3
Que j'ai suivi à la lettre (en modifiant les requêtes mysql par mysqli). J'arrive à afficher la carte mais pas les points.

Cela fait des heures et des heures que je galère dessus, si quelqu'un veut bien prendre un peu de son temps pour résoudre mon souci, ça serait sympa ! ^^
Merci d'avance. :)
