{#
    By default, forms enable client-side validation. This means that you can't
    test the server-side validation errors from the browser. To temporarily
    disable this validation, add the 'novalidate' attribute:

    {{ form_start(form, { method: ..., action: ..., attr: { novalidate: 'novalidate' } }) }}
#}

{{ form_start(form, { method: 'POST', action: path('comment_new', { 'postSlug': post.slug }) }) }}
    {#  instead of displaying form fields one by one, you can also display them
        all with their default options and styles just by calling to this function:

        {{ form_widget(form) }}
    #}

    <fieldset>
        <legend>{{ 'title.add_comment'|trans }}</legend>

        {# Render any global form error (e.g. when a constraint on a public getter method failed) #}
        {{ form_errors(form) }}

        <div class="form-group {% if not form.content.vars.valid %}has-error{% endif %}">
            {{ form_label(form.content, 'label.content', { label_attr: { class: 'hidden' }}) }}

            {# Render any errors for the "content" field (e.g. when a class property constraint failed) #}
            {{ form_errors(form.content) }}

            {{ form_widget(form.content, { attr: { rows: 10 } }) }}
        </div>

        <div class="form-group">
            <button class="btn btn-primary pull-right" type="submit">{{ 'action.publish_comment'|trans }}</button>
        </div>
    </fieldset>
{{ form_end(form) }}
