Check out the docs on filtering and sanitizing.
If you want to be extra safe, you can do
$name = $this->request->getPost('name', 'string');
Or you can get the whole request, and then use the \Phalcon\Filter class when assigning your values to the object
$filter = new \Phalcon\Filter();
$data = $this->request->getPost();
$object->name = $filter->sanitize($data['name'], 'string');
aha.
So this form: $this->request->getPost() escapes everything automatic?
