isValid ([array $data], [object $entity]) , What's the second parameter used for , and what should I do if I want change the valide condition ?
In what context are you finding that isValid function? Is it an object function? In a controller? Model? We need more info.
hello! i have questions too :)
for example, in controller
$form - is a form $data - request->getPost() $news - model
if (!$form->isValid($data, $news)) { foreach ($form->getMessages() as $message) { $this->flash->error($message); }
