Nom de playliste XML Dynamique

**rollingbox** · 02/10/2008, 15h17

Bonjour,

Voilà, j'ai un player Mp3 avec playliste XML. Jusqu'ici tout va bien.

Il y a un fichier *.SWF, un *.FLA, un *.AS et un *.FLP.

Dans le FLA il n'y a aucun code AS3, tout le code est dans le fichier AS qui est un package et le fichier FLP qui comporte toutes les function des boutons...

Voici le code du fichier AS :

Je sais... rien que ça... mais bon...

Dans ce fichier AS, on demande de charger les données d'un fichier XML (playlist_1_1.xml)

Ce fichier XML est créé et/ou mis à jour grâce à une page PHP conteneur du player SWF. A chaque fois que la page est ouverte, php met à jour les données et le nom du fichier XML de type playlist_variable1_variable2.xml.

Pour créer et vérifier le lecteur j'ai donc fais des test avec le nom direct d'un fichier xml créé dynamiquement par ma page php. (playlist_1_1.xml) Bien entendu les deux variables ici sont 1 et 1.

Code :

public var position:Number;

		public function Mp3Main() {
			position = 0;
			sndTrans = new SoundTransform(vol_mc.percent);
			url = new URLRequest("playlist_1_1.xml");
			xmlLoad = new URLLoader(url);
			xmlLoad.addEventListener(Event.COMPLETE, xmlComplete);

Dans mon fichier php j'ai une flashvars de type: flashvars=playlist_variable1_variable2.xml. Cela permet de créer dynamiquement le nom de mon fichier xml dans le conteneur.

L'objectif pour moi serait de pouvoir indiquer au fichier AS de récupérer cette flashvar qui contient le nom de mon fichier XML généré par php.

Si quelqu'un avait une petite idée là dessus, je suis preneur.

En vous remerciant par avance.

Tony.
