To render a form, within a .twig template I have:
{{ form_start(form) }}
{{ form_row(form.title) }}
{{ form_row(form.description) }}
{{ form_end(form) }}
I get
<form name="job" method="post" action="/myname/Job/create">
<div><label for="job_title" class="required">Title</label>
<input type="text" id="job_title" name="job[title]" /></div>
<div><label for="job_description" class="required">Description</label>
<input type="text" id="job_description" name="job[description]" /></div>
</form>
but I need to render it something like:
<form name="job" method="post" action="/myname/Job/create">
<div><label for="job_title" class="required">Title</label>
<input type="text" id="job_title" name="job[0][title]" /></div>
<div><label for="job_description" class="required">Description</label>
<input type="text" id="job_description" name="job[0][description]" /></div>
</form>
the point being to insert the index [0]. (This I need to apply a JS trick)
I looked at form_div_layout.html.twig, I understand that the rendering of a form is given by the lines under {%- block widget_attributes -%}, but I do not see how Symfony 2.7 assigns that piece of html to {{ full_name }}.
