No entiendo realmente para que usar esa clase, se me hace más complicada que usar el array $_FILES junto con move_uploaded_file, es lo más sencillo, si quieres checar la extensión es trivial también, puedes usar una función así:
Código PHP:
Ver originalclass Upload
{
private $destDir;
private $checkExtensions;
private $extensions;
private $errors = array(); private $upload_errors = array( UPLOAD_ERR_INI_SIZE => "Larger than upload_max_filesize.",
UPLOAD_ERR_FORM_SIZE => "Larger than form MAX_FILE_SIZE.",
UPLOAD_ERR_PARTIAL => "Partial upload.",
UPLOAD_ERR_NO_FILE => "No file.",
UPLOAD_ERR_NO_TMP_DIR => "No temporary directory.",
UPLOAD_ERR_CANT_WRITE => "Can't write to disk.",
UPLOAD_ERR_EXTENSION => "File upload stopped by extension.",
UPLOAD_ERR_EMPTY => "File is empty." // add this to avoid an offset
);
public function __construct
($destDir, $checkExt = false, array $extensions = array()) {
$this->destDir = $destDir;
$this->checkExtensions = $checkExt;
$this->extensions = $extensions;
}
public function setExtensions
(array $extensions) {
$this->extensions = $extensions;
return $this;
}
public function getExtensions()
{
return $this->extensions;
}
public function setCheckExtensions($checkExt = true)
{
$this->checkExtensions = $checkExt;
return $this;
}
public function getCheckExtensions()
{
return $this->checkExtensions;
}
public function getErrorsFor($name)
{
return $this->errors[$name];
}
public function getErrors()
{
return $this->errors;
}
public function addError($name, $error) {
if (!isset($this->errors[$name])) $this->errors[$name] = array();
$this->errors[$name][] = $error;
return $this;
}
public function moveFile($name)
{
if (!$this->isValid($name)) {
return false;
}
throw new RuntimeException("can't move file to destination dir: {$destDir}");
}
return true;
}
public function getName($name)
{
if (!$this->isValid($name)) {
return false;
}
return $_FILES[$name]['name'];
}
public function getExtension($name)
{
if (!$this->isValid($name)) {
return false;
}
$fileInfo = pathinfo($_FILES[$name]['name']);
return $ext;
}
private function isValid($name)
{
if (!isset($_FILES[$name])) { $this->addError($name, "missing in \$_FILES");
return false;
}
if ($_FILES[$name]['error'] != UPLOAD_ERR_OK) {
$translated = $this->translateUploadError($_FILES[$name]['error']);
$this->addError($name, $translated);
return false;
}
$this->addError($name, 'file wasn\'t uploaded by POST, possible attack');
return false;
}
if ($checkExt) {
$ext = $this->getExtension($name);
if (!in_array($ext, $this->extensions)) { $this->addError($name, "invalid extension: {$ext}");
return false;
}
}
return true;
}
private function translateUploadError($error)
{
return $this->upload_errors[$error];
}
}
Uso:
Código PHP:
Ver original$upload = new Upload
('./uploads/', true, array('jpg', 'gif')); if ($upload->moveFile('file')) {
$name = $upload->getName('file');
echo "{$name} uploaded correctly";
} else {
foreach ($upload->getErrorsFor('file') as $error) {
echo $error;
}
}
