Symfony2 - form_start function customise in twig

Question

Form helpers form_start and form_end are useful in twig:

{{ form_start(form) }}
{{ form_end(form) }}

I can customise

Answer 1

As form_start has the following signature,

form_start(view, variables)

And as class doesn't represent a valid variable name. You need to specify your class as a key/value array using the attr attribute.

Then, try ...

{{ form_start(form, {'action': 'myaction', 'attr': {'class': 'your_class_name'}}) }}

Also ...

• You should be sure that your Type fileds are well defined in order to let the form_start helper set the right form-enctype.

• The form_enctype(formView) helper is deprecated since Symfony 2.3.
