Ciao, avete bisogno di effettuare un'upload multiplo con php?? Bene, il seguente codice potrebbe fare al caso vostro
prima di tutto vi consiglio di leggere questo: Upload con PHP
Il tutto si compone di 3 file:
config.php <-- il file di configurazione
upload.class.php <-- il file della classe per eseguire l'upload
esterno.js <-- file javascript con il codice per mostrare i campi file multipli (http://www.xaraya.com/index.php/xarbb/topic/269)
Per fare i primi test create un file index.php con il seguente codice:
il codice potrà essere aggiornato/modificato aggiungendo nuove funzioni, così come la parte HTML del form (uso di fogli di stile, etc.).codice:<?php error_reporting(E_ALL); require_once("config.php"); require_once("upload.class.php"); // ISTANZIA LA CLASSE $upload=new upload(); // SE L'ARRAY $_FILES CONTIENE QUALCOSA ESEGUI IL CODICE PER CARICARE I FILE if (count($_FILES) > 0) $upload->caricafile(); // ALTRIMENTI MOSTRA IL FORM PER L'UPLOAD else $upload->mostraform(); ?>
