Symfony2 Forms: Generating checkboxes

currently i have a form, that generates a Drop-Down-Select from my category-entity:

        $builder
            ->add('category', 'entity',
                    array('class' => 'TrackerMembersBundle:Category',
                            'property' => 'title',));

Now i want to generate checkboxes instead, where i can select more than one option...i searched the symfony2 documentation, but could not find an easy way to do it directly from my Entity.Any idea?

Because EntityType has parent the ChoiceType, you can use any option from the choice type.

In your case, configuring your category field as following would render checkboxes:

$builder
    ->add('category', 'entity', array(
        'class' => 'TrackerMembersBundle:Category',
        'property' => 'title',
        'multiple' => true,
        'expanded' => true,
    )
);

Note the usage of multiple AND expanded in the options.

Adding 'multiple' => true to the option array (the last one where class and property are) gives you a multi-select.

Then you could override the choice_widget block, using form theming.

Something like this might work:

{% block choice_widget %}
{% spaceless %}
    {% for choice, label in choices %}
        <label>
            <input type="checkbox" value="{{ choice }}"{% if _form_is_choice_selected(form, choice) %} selected="selected"{% endif %}>
            {{ label|trans }}
        </label>
    {% endfor %}
{% endspaceless %}
{% endblock choice_widget %}

Try

       $builder
        ->add('category', 'checkbox',
                array('class' => 'TrackerMembersBundle:Category',
                        'property' => 'title',));#
