Symfony2 and layout / configuration (required / help / errors)

Maybe I'm missing something, and I hope this is done very easily.

I have a form, and in the end I want to get the following result:

Fields that:

  • are required / required
  • there is a mistake now
  • have help

should get an extra a-Tag after the label and an extra div filled with help and / or an error, if applicable.

What I need is that the required fields get a-Tag using this:

{% use 'form_div_layout.html.twig' with field_label as base_field_label %}

{% block field_label %}
    {{ block('base_field_label') }}

    {% if required %}
        <a href=""><span>&nbsp;</span></a>
    {% endif %}
{% endblock %}

So, I already tried different versions of this:

{% use 'form_div_layout.html.twig' with field_label as base_field_label %}

{% block field_label %}
    {{ block('base_field_label') }}

    {% if required or help is defined %}
        <a href=""><span>&nbsp;</span></a>
    {% endif %}
{% endblock %}

{% block field_row %}
    {% spaceless %}
        <div class="row">
            {% if required or help is defined %}
                <div>
                    {{ form_errors(form) }}
                    {{ help }}
                </div>
            {% endif %}

            {{ form_label(form) }}
            {{ form_widget(form, { 'attr': {'class': 'grid_4'} }) }}
        </div>          
    {% endspaceless %}
{% endblock field_row %}

And I can't get this to work.

So my questions are:

  • Where can I get help text that may also contain HTML? I tried this in form builderwithout success - but at least with the exception of:

    $builder    ->add('subject', 'text', array(
    'label' => 'Subject',
    'help' => 'Can be formatted content with <strong>HTML-Elements</strong>',
    ));

  • , ( ), , ? {{ form_errors(form) }} , , field_row.
