我有一个表单,我试图上传图像并尝试将其存储在数据库中.我的控制器代码是:

class OlxProductsController extends AppController{
public function post(){
    if($this->request->is('post')) {
            if ($this->request->data['OlxProduct']['img_upload']) {
                $file = $this->data['OlxProduct']['img_upload']; //put the data into a var for easy use
                //   print_r($file);
                $filename = str_replace(" ", "-", rand(1, 3000) . $file['name']);
                move_uploaded_file($file['tmp_name'], WWW_ROOT . 'img/uploads/' . $filename);
                //echo $filename; die();
                $this->request->data['OlxProduct']['img_upload'] = $filename;
            } else {
                unset($this->request->data['OlxProduct']['img_upload']);
            }

            $this->OlxProduct->save($this->request->data);
            $this->Session->setFlash('posted successfully');
            $this->redirect(array('controller' => 'OlxUsers', 'action' => 'account'));
    }
    else {
            $this->Session->setFlash('ad has not been saved');
    }
  }
}
