Script per caricare e cancellare files sul server
Salve a tutti,
in rete ho trovato questo script che permette di caricare e cancellare files in una specifica cartella del sito.
Il nome della cartella di default risulta essere files. Il programmatore "promette" che è possibile cambiare in nome della cartella, ma a quanto pare una volta cambiato il nome non è più possibile cancellare i files, ma solo caricarli.
E' possibile cambiare il nome della cartella qui:
Codice PHP:
public $upload_dir = 'files/'; // Name of the upload directory - create it yourself and chmod it to 777
A metà script circa, c'è questa riga:
Codice PHP:
$upload_url = $url_dir."/files/";
Vorrei mettere 2 demo (una con la cartella files e uno con un altro nome della cartella) ma temo sia un'operazione poco sicura.
Il mio livello di conoscenza di php è nullo, spero possiate darmi una mano.
Codice PHP:

Script modificato e reso in Italiano
Grazie, confermo con archiviazone io lo uso per il mio sito e con qualche modifica l'ho reso in italiano, ho agg. varie estensioni, ho modificato il testo e ho aumentato il limite di trasferimento a 20MB
:wink:

> cambio directory a cui puntare
Citazione:
Originalmente inviato da
circuitipertutti
Infatti ho visto che il limite impostabile è default, 5MB e 10MB e ovviamente l'ho impostato su 10MB
CIao A tutti...spero qualcuno mi riesca/possa rispondere anche se il post è vecchiotto.
Avrei la necessità di usare questo ottimo script ma con una varibile: dovrei cambiare la directory a cui punta lo script tramite post all'interno dello scrip stesso.
In pratica l'utente dovrebbe scrivere in che sotto cartella andare, e lo script dovrebbe reindirizzare alla sottocartellla
Io ho provato cosi....
<form action=miofile.php method="post">
<input type="text" name ="cartella" ><br />
la cartella che seleziono poi la riprendo con
$cartella= $_POST['cartella'];
e dare a questo "public $upload_dir= miadirectory/';" il nuovo valore estratto contenuto in $cartella
ma il problema è che non riesco a far digerire questo nuovo percorso allo script
Non sono molto ferrato sulla dinamica delle matrici public..qualcuno mi portrebbe aiutare?
Grazie :oops:
Mario
