seleizonare e cancellare un file

[0-c00l]

Prova così allora:

 <?php
$id = $this->row->id;
$dir = "mydir";
// Open a known directory, and proceed to read its contents
if (is_dir($dir)) {
echo <<<EOT
<form action="" method="POST" onSubmit="confirm('Sicuro di voler cancellare questo file?');"><select name="file">
EOT;
    if ($dh = opendir($dir)) {
        while (($file = readdir($dh)) !== false) {
            $ext = substr($file, strrpos($file, '.') + 1);
            if ($ext == 'pdf'){
            echo '<option value="'.$file.'">'.$file.'</option>';
            }
        }
        closedir($dh);
    }
echo '</select>

<input type="submit" value="Cancella" name="canc" /></form>
';
}
if(isset($_POST['canc'])) {
$file_selezionato = $_POST['file'];

if(unlink("/".$dir."/".$file)) {
echo 'File cancellato correttamente.';
} else {
echo 'Errore: riprovare.';
}
 }
?>

Se non va così:

 <?php
$id = $this->row->id;
$dir = "mydir";
// Open a known directory, and proceed to read its contents
if (is_dir($dir)) {
echo <<<EOT
<form action="" method="POST" onSubmit="confirm('Sicuro di voler cancellare questo file?');"><select name="file">
EOT;
    if ($dh = opendir($dir)) {
        while (($file = readdir($dh)) !== false) {
            $ext = substr($file, strrpos($file, '.') + 1);
            if ($ext == 'pdf'){
            echo '<option value="'.$file.'">'.$file.'</option>';
            }
        }
        closedir($dh);
    }
echo '</select>

<input type="submit" value="Cancella" name="canc" /></form>
';
}
if(isset($_POST['canc'])) {
$file_selezionato = $_POST['file'];

if(unlink("./".$dir."/".$file)) {
echo 'File cancellato correttamente.';
} else {
echo 'Errore: riprovare.';
}
 }
?>
