你可以像往常一样在PHP中。我只是这样做了几天前像这样：

You can do it "as usual" in PHP. I just did it a few days ago like this:

$path = "/img/avatars/";
$dir = getcwd().$path;
$avatarFile = "$dir$id.png";

if (isset($this->data['User']['avatar']) && $this->data['User']['avatar']['error'] == 0) {
                $avatar = $this->data['User']['avatar'];
                if (!is_uploaded_file($avatar['tmp_name'])) $this->Utils->panic($avatar);

                if (in_array($avatar['type'], array('image/jpeg','image/pjpeg','image/png'))) {

                    // load image
                    list($width,  $height) = getimagesize($avatar['tmp_name']);
                    $width = $height = min($width, $height);

                    if (in_array($avatar['type'], array('image/jpeg','image/pjpeg')))
                        $source = imagecreatefromjpeg($avatar['tmp_name']);
                    else
                        $source = imagecreatefrompng($avatar['tmp_name']);

                    // resize
                    $thumb = imagecreatetruecolor(128, 128);
                    imagecopyresized($thumb,  $source,  0,  0,  0,  0,  128,  128,  $width,  $height);

                    // save resized & unlink upload
                    imagepng($thumb, $avatarFile);

                    $success &= true;
                } else {
                    $this->User->invalidate('avatar', __("Only JPG or PNG accepted.",true));
                    $success &= false;
                }

                unlink($avatar['tmp_name']); // Delete upload in any case
            }

它甚至会为你调整大小到128x128，您可以跳过它，只需将上传的图像重命名为目标目录。

It's even going to resize it for you always to 128x128, you can skip that and just rename the uploaded image to the target dir. Google will also help you out, there is nothing Cake specific for file uploads.

上传表单：

echo $form->create('User', array(
    'enctype' => 'multipart/form-data',
    'type' => 'post',
));
echo $form->input('avatar', array('type' => 'file', 'label' => __('Avatar:',true)));
