ho un sistema per l'upload di immagini, e conseguente ridimensionamento, ma da un un paio di giorni non va. Ho fatto delle modifiche ai file, anche se non avrebbero dovuto riguardare questa parte, ma sfortunatamente le vecchie copie sono state sovrascritte per errore, quindi non posso recuperarle...
Per carcare di capire dov'è il problema, mi sono creato una testimg.php, con solo la funzione di upload. Questo il codice:
Codice PHP:
<?PHP
require "config.php";
include "upload.class.php";
$link = mysql_connect($host, $dbuser, $dbpass)
or die("Impossibile connettersi al database");
mysql_select_db($dbname)
or die("Impossibile selezionare il database");
$img = $_POST["image"];
echo $img;
if ($img != "") {
$upload = new upload("", "400000", "newsimg");
$go = $upload -> putFile ("image");
if ( $go ) {
$filePath = $upload -> splitFilePath ($go);
$img_name = $filePath[filename];
}
$mini = $upload -> miniatura ($go,"newsimg",100,100,"thumb_");
if ( $mini ) {
$filePath = $upload -> splitFilePath ($mini);
$thmb_name = $filePath[filename];
}
}

quindi provo ad inserire i dati nel db.
Però non inserisce nulla, e l'echo della variabile $img non dà ugualmente nulla!
Questo è il codice del file upload.class.php (che però non ho modificato...):

Da cosa può dipendere?
