Symfony2 dynamic form generation

Question

I have mysql 2 tables: user_profile_field and user_profile_data with following columns:

user_profile_field:

-id (integer)
-field (string)
-category(string) 

user_profile_data:

-id (integer)
-user_id (integer)
-field_id (integer) references user_profile_field(id)
-data (string)

I also have defined 2 Doctrine entities that map this relation. I need dynamicaly to create a form for updating user_profile_data. The form input type for each row of user_profile_field depends on user_profile_field:category column (3 possible values correspond to different input types: text, textarea and choice field) ...

Im not sure how to create the form and form type entity via 'Symfony2' way ?

Any help or suggestion appreciated ...

The Symfony 2 user documentation suggests the use of form events to generate a dynamic form: http://symfony.com/doc/current/cookbook/form/dynamic_form_generation.html
