财产＆＃34; item＆＃34;也不是其中一种方法

Question

我有这个formBuilder。

public function buildForm(FormBuilderInterface $builder, array $options)
{
    $builder
        ->add('dateStart','genemu_jquerydate',array('required'  => true, 'widget' => 'single_text'))
        ->add('dateFinish','genemu_jquerydate',array('required'  => true, 'widget' => 'single_text'))
        ->add('image', 'genemu_jqueryimage', array(
        'configs' => array(
            'auto' => true,
            'multiple' => false
        )))
        ->add('items', 'genemu_jqueryselect2_entity', array(
            'class' => 'Acme\sampleBundle\Entity\Item',
            'property' => 'name',
            'configs' => array(
                'multiple' => true
                )
            )
        )
        ;
}

当我提交它时会抛出此错误：

有什么建议吗？

解决。只需在数组中添加多个就可以了。

        ->add('items', 'genemu_jqueryselect2_entity', array(
            'class' => 'Acme\sampleBundle\Entity\Item',
            'property' => 'name',
            'multiple' => true,
            'configs' => array(
                'multiple' => true
                )
            )
        )
