File sovrascritti in upload

[filippo.toso]

Prova a sostituire la riga:

$remote_file = "image_files/".$_FILES["image_upload_box"]["name"]; 

con:

$remote_file = "image_files/" . $_FILES["image_upload_box"]["name"];
$ext = substr($remote_file, strrpos($remote_file, '.'));
$remote_filename = substr($remote_file, 0, -strlen($ext));
$i = 1;
while (file_exists($remote_file)) {
    $remote_file = $remote_filename . $i . $ext;
    $i++;
}
