I have table with this fields:
id, ch1, ch2, .., ch15
and 62 lines (id = 1 upto 62, and other fields = 0 by default). I need to create single form, where i can edit (not insert nor delete) all ch1-ch15 fields in all lines.
I've seen articles about embedded forms, but they're all about adding new line in database. I need only to edit existing lines.
And now the question: How can I bind each entity to each Form in Embedded form collection? Or there is another way to solve my problem?
With embedded Forms you can only edit existing entities within their relations if you want to.
For example :
If you have a Person entity with multiple Address entities.
You need to implement a Person form and an Address form.
Inside of your Person Form you need to add a widget named after the attribute which stores the addresses and mark this attribute beein a subform (in this case the Address form)
If you save this form and call the $form->bind() method all of the values will be bind to the related entities.
For implementation details read the embedded forms article inside the docs
http://symfony.com/doc/current/book/forms.html#embedded-forms
hope it helps ;)
