label_attr arguments ignored in bootstrap_3_layout

[jonathanbull]

I'm using the bootstrap_3_layout. If I use form_label arguments, they are ignored:

{{ form_label(form.foo, 'Foo', {'label_attr': {'class': 'bar'}}) }}

<label>
   *default humanized label*
</label>

This does not happen with form_div_layout:

{{ form_label(form.foo, 'Foo', {'label_attr': {'class': 'bar'}}) }}

<label class="bar">
   Foo
</label>

@jonathanbull Unfortunately, I was not able to reproduce your issue. Does this happen for all form types? Could you provide a fork of the Symfony Standard Edition that reproduces this?

[jonathanbull]

@xabbuh Sorry, I've just realised that this only affects checkboxes under the bootstrap layout:

{{ form_widget(form.fooCheckbox) }}
{{ form_label(form.fooCheckbox, 'Foo') }}

Could you please give it another go? If you're still unable to reproduce it, I'd be happy to provide that fork.

@jonathanbull The checkbox type is a bit special when using the Bootstrap theme as the label will already be handled by the widget. So form_label() will render nothing and you will have to pass label options to form_widget():

{{ form_widget(form.foo, 'Foo', {'label_attr': {'class': 'bar'}}) }}

By the way, this will soon be reflected in the documentation on symfony.com when symfony/symfony-docs#5460 is merged.
