Zend Framework 2 - Validating a form from multiple sets of input filters?

Question

My ZF2 uses a simple structure that I have seen throughout, with input filters installed in the models and applied to the form during validation. But I really hit the wall here. How do you handle validation for a form that has some fields that need to be checked against one model, and some fields that need to be checked against another?

My scenario: I use one form to insert 2 records in 2 tables of my database (adding a user and adding a donation related to this user). Some fields will appear in one table, others in a second table.

As I said, my input filters are stored at the model level.

If my whole scenario included only one model / table, for example, storing one donation and nothing else, I would go as follows:

$donation = new Donation(); $form->setInputFilter($donation->getInputFilter()); $form->setData($request->getPost()); if ($form->isValid()) { $donation->exchangeArray($form->getData()); $this->getDonationTable()->saveDonation($donation); 

I can do higher.

But I'm trying to analyze and validate form data on two sets of inputFilters, which I collect from two models. One for the data that will go to the donation model, and one for the data that will be transferred to the user. So I get the following:

 $donation = new Donation(); $user = new User(); $form->setInputFilter($donation->getInputFilter()); 

Then I would add something like: (obviously does not exist)

$ form-> addInputFilter ($ user-> getInputFilter ());

So I could continue ...

 $form->setData($request->getPost()); if ($form->isValid()) { // add donation // add user 

I am surprised that I did not find anything about this on the Internet, since I am using models and inputFilters incorrectly? How do you handle validation for a form that has some fields that need to be checked against one model, and some fields that need to be checked against another?

Fieldsets (form collections) are what you are looking for. The official documentation is here:
