Symfony Forms：选项不起作用

Question

我有一个 symfony 3.4 表单类 UserForm，我在 setDefaultOptions 方法中设置了选项 'password_field' => false：

public function setDefaultOptions(OptionsResolver $resolver)
{
    $resolver->setDefaults(array(
        'data_class' => User::class,
        'password_field' => false,
    ));
}

在我使用此表单的控制器中，我设置了选项：

    $form = $this->createForm(UserForm::class, $user, [
        'password_field' => false,
    ]);

通过在浏览器中加载表单，我收到以下错误消息：

The option "password_field" does not exist. Defined options are: "action", "allow_extra_fields", "attr", "auto_initialize", "block_name", "by_reference", "compound", "constraints", "csrf_field_name", "csrf_message", "csrf_protection", "csrf_token_id", "csrf_token_manager", "data", "data_class", "disabled", "empty_data", "error_bubbling", "error_mapping", "extra_fields_message", "inherit_data", "invalid_message", "invalid_message_parameters", "label", "label_attr", "label_format", "mapped", "method", "post_max_size_message", "property_path", "required", "translation_domain", "trim", "upload_max_size_message", "validation_groups".

一切对我来说都是正确的，如文档中所述。有什么想法吗？

Answer 1

setDefaultOptions() 已被弃用，取而代之的是 configureOptions()。 Symfony 2.x 中使用了这个方法名

见UPGRADE-3.0.md。

configureOptions() 已在 Symfony 3.x 中使用

所以你必须替换方法名；）

例子：

/**
 * @param OptionsResolver $resolver
 */
public function configureOptions(OptionsResolver $resolver)
{
    $resolver->setDefaults([
        'data_class' => User::class,
        'password_field' => false
    ]);
}
