un script php consente di cancellare i file
salve a tutti!! ho trovato questo script su un sito web funziona benisimo, su tutte le sue funzioni, lo posto anche, cosi potrebbe essere utile a qualche utente, ma cmq la cosa strana e che se modifico la cartella per visualizari i file :
Codice HTML:
$upload_dir = "tipocartella/";
$upload_url = $url_dir."tipocartella/";
$message ="";
if (!is_dir("tipocartella")) {
cosi non mi consente piu di cancellare i file con il tasto (X), ma upload continua a funzionare, e visualizare i file nella cartella, ma non funziona piu il tasto per eliminare i file se cambio il nome della cartella, non riesco a capire dove sia errore, cosa cambia se gli modifico la cartella.
Codice PHP:
<?php
$MAX_SIZE = 2000000;
$FILE_EXTS = array('.jpg','.gif','.png');
$DELETABLE = true;

$message ="";
if (!is_dir("files")) {

if (!chmod($upload_dir,0755))

}
if ($_REQUEST[del] && $DELETABLE) {
