Question

如何使用外部数据阵列填充选项选项？

$builder->add('gender', 'choice', array(
    'choices' => [array from webservice or other class]
));

文档仅显示简单的静态数组 http://symfony.com/fr/doc/2.7/reference/forms/types/choice.html#choices

我试过了：

控制器：

$event = new Event();
$form = $this->createForm(new EventType($this->get('api')), $event);

表格：

class EventType extends AbstractType
{
    protected $myservice;

    public function __construct($myservice)
    {
        $this->myservice = $myservice;
    }

    public function buildForm(FormBuilderInterface $builder, array $options)
    {
        $builder
            ->add('titre')
            ->add('id_rubrique', 'choice', array(
                'choices' => $this->myservice->getRubriques
        ;
    }

    ....
}

这是正确的解决方案吗？

Answer 1

将表单定义为服务：

services:
    my.form:
        class: EventType
        arguments:
            - @api

然后在控制器中：

$event = new Event();
$form = $this->createForm('my.form', $event);

Answer 2

例如

->add('education', 'choice', array('label' => 'Education *','choices' => $this->getEducation(), 'required' => true, 'empty_value' => 'select', 'empty_data'  => null))

$ this-＆gt; getEducation（）是数组

// Array（'option1Value'=＆gt;'option1Name'...

symfony表单选择字段：从外部数据源设置选项选项默认数据
