Question

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?

Answer 1

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 %}
