Script Gallerie Image en mode Descending

Posté : 15 sept. 2012, 13:32
par padcmoi
Bonjour, sur mon site web j'ai introduis un script pioché sur le web, donc par défaut pour afficher la plus vieille image à la plus récente, et moi je voudrais avoir le contraire c'est à dire les dernières images ajouté se positionnent en premier et non en dernier, j'ai essaye de modifier le USORT en Asort, Sort, Arsort ect ... mais ça crée d'autre problème.

Ce script je l'ai téléchargé sur ce site, en voici la demo: http://jensensiu.free.fr/index.php

voici le script :
<?php 
require("conf.php");

//error_reporting(E_ALL); // afficher les erreurs
error_reporting(0); // ne pas afficher les erreurs

Bonjour,

Tout ça pour un slide :o) Waoo y a du boulot !
        for ($i=0;$i < count($listFile2); $i++) {
Tu changes ça

Il faut inverser le for en partant de l'index le plus élevé et décrémenter au lieu d'incrémenter : 
for($i= count($listFile2) ;$i>0;$i--)
En gros.
Enfin je crois je ne suis pas un pro.
Bon codage

Non j'ai essaye et même ça ne change rien, ni même l'ordre d'apparition des images.
