symfony get form attributes

Question

I know that it is dumb question to ask but I need to know can I get form widget attributes through PHP I mean not a value but id, class or even parent or child. If I set them.

<label name = '{{ item.modulePath }}' id = 'main' class = 'menu_label' **parent = ''** **childs = ''**>{{ item.modulePath }}</label>

If it is not possible then how can I make JS function before form validation and post array to the form as value?

<form action="{{ path('menu_manage') }}" method="post">

Yes I could get values and submit form to JS and then by JS get all attributes and then through ajax send it to a PHP handler. But it would be longer, because I will need to include all components that have this action to the handle information to place where I need it.

Here is an example how to realize it

You can call get() method on form field in template, eg having a form in form with field item :

{{ form.item.get('id') }}

The class - only if set - can be retrieved like this:

{{ form.item.get('attr').class }}
