How to change the text in a form submit button (in the template) isn't clear

[thepurpleblob]

The "normal" method of overriding the default text on controls is explained in the documentation and is to use {{ form_label( form.thing, 'New text') }}. This doesn't make any sense (and is completely ignored) for submit type controls.

The actual method is to do {{ form_widget( form.save, 'Press this!' ) }}. However, that isn't specifically mentioned as far as I can see. A couple of lines about this would have saved me a bit of time!

Checking http://symfony.com/doc/current/reference/forms/types/submit.html#label this is already documented. It is not exactly your method, which seems to be some default assignation to the 'label' attribute, but should server for what you wanted to achieve.

Or am I missing something?

I think we could solve this pretty easily by showing a few of the submit rendering examples on the "form" chapter page with their labels being overridden. Doing this is especially common, so I think it makes sense. @ricardclau is right that it's doc'ed, but probably not in the place that people will be looking first.

So, easy pick on this one to make some submit button-rendering examples in book/forms.rst have an overridden label.

Thanks!

@weaverryan Fair enough, and I think it makes sense to have it documented in the form creation itself (instead of hacking in the twig rendering)

I will do it unless there is any objection, long time no doing PRs :)

Fixed thanks to @ricardclau!
