Access POST data from a form in SonataAdmin

Question

I have a simple question, how can I access the raw POST data returned by a form in sonataAdmin?

I have a page that is creating forms using Javascript and I need to retrieve the data in those forms. The problem is that those forms are not attributes of the entity so I can't have Sonata admin linking them automatically for me.

Answer 1

The base admin class provides a getRequest method which returns the Request object.

Something like...

$request = $this->getRequest();
$postValue = $request->request->get('parameterName');

Answer 2

There even seems to be "smarter" and may be more secure version:

public function preUpdate($object)
{
    $uniqid = $this->getRequest()->query->get('uniqid');
    $formData = $this->getRequest()->request->get($uniqid);
    var_dump($formData);exit;
}
