我正在尝试为我的配置模块制作一些输入复选框，但选择小部件不起作用。
所以它只适用于单选按钮和菜单，而对于多个菜单和复选框我有一个错误：
给定“数组”、“字符串”类型的预期参数
编码：
$builder->add('value', 'choice', array
(
'label' => $this->item->getTitle() . ':',
'choices' => array('1' => 'one', '2' => 'two'),
'multiple' => true,
'expanded' => true,
)
);
这是一个例子。
编辑：
因此，在我的配置包中，我有很多不同类型的输入来更好地描述配置值，对于每一个，我都会呈现正确的小部件。我对所有小部件都没有任何问题，除了用于选择小部件的复选框和菜单多个，收音机和菜单工作正常。
这是表单类：

/**
