Symfony Form - 类型为"string或Symfony\Component\Form\FormTypeInterface"的预期参数,给出"数组"

Question

我创建了一个带有学说的表格.如果我没有通过任何选项,它会工作,如下所示:

$builder
    ->add('name')
    ->add('password', 'password')
    ->add('password_repeat', 'password')
    ->add('email', 'email')
    ->add('save', 'submit')
;

但是,如果我添加一个带有选项的数组,就像文档(http://symfony.com/doc/current/book/forms.html#book-form-creating-form-classes)那样,我收到的错误是:

预期参数类型为"string或Symfony\Component\Form\FormTypeInterface","数组"给出

这是由学说创建的formtype:

<?php

namespace MainBundle\Form;

use Symfony\Component\Form\AbstractType;
use Symfony\Component\Form\FormBuilderInterface;
use Symfony\Component\OptionsResolver\OptionsResolverInterface;

class UserType extends AbstractType
{
/**
 * @param FormBuilderInterface $builder
 * @param array $options
 */
public function buildForm(FormBuilderInterface $builder, array $options)
{

    $builder
        ->add('name') //if I put ->add('name', array('label' => 'Your name')) I get the error
        ->add('password', 'password')
        ->add('password_repeat', 'password')
        ->add('email', 'email')
        ->add('save', 'submit')
    ;

}

/**
 * @param OptionsResolverInterface $resolver
 */
public function setDefaultOptions(OptionsResolverInterface $resolver)
{
    $resolver->setDefaults(array(
        'data_class' => 'MainBundle\Entity\User'
    ));
}

/**
 * @return string
 */
public function getName()
{
    return 'mainbundle_user';
}
}

您必须在添加选项之前指定字段的类型

 $builder->add('name', 'text', array('label' => 'Your name'))
