Question

我有一些自定义路由：

---
Name: mysiteroutes
---
Director:
  rules:
    'signup//$Action/$Data/$Form': 'SignupController'
---
Name: modelascontrollerroutes
After: '#rootroutes'
---
Director:
  rules:
    '': 'HomePage_Controller'
    '$URLSegment/$Action/$ID': 'BaseController'

注册控制器：

class SignupController extends Page_Controller {

    private static $allowed_actions = array(
        'submit'
    );

    public function index(SS_HTTPRequest $request) {
        $form = Form::create(
            $this,
            __FUNCTION__,
            FieldList::create(
                EmailField::create('Email', 'Email')
            ),
            FieldList::create(
                FormAction::create('submit', 'Submit')->setAttribute('class', 'btn btn-success')
            ),
            RequiredFields::create('Email')
        );
        return $this->customise(array('Form'=>$form))->renderWith(array("Signup", "Page"));
    }

    public function submit($data, $form = null) {
        $form->addErrorMessage("Test", "Test error message",'bad');
        return $this->redirectBack();
    }
}

显示表单但不显示任何错误消息。当我去提交它时，它会转到（当然）SignupController / submit，返回404.我已经setFormAction(Controller::join_links(BASE_URL, "signup", 'submit'))添加了$form，然后数据通过了$form是null，我无法更新它。我可能会使它成为一个实例变量但是我可以使用正确的SS路由来解决这个问题。我应该更新我的路由以获取$form还是其他错误？

路由中不需要$Data和$Form参数，这些参数将在POST数据中。

其次，您不需要在submit中使用allowed_actions方法，因为它不会被路由触发。

要解决这个问题你应该; 添加功能链接

public function link($action = null)
{
    return $this->join_links('signup', $action);
}

因此，您将被重定向到signup/...

然后将索引函数更改为此;

public function index() {
    $form = Form::create(
        $this,
        '', //so it will redirect you to 'signup', instead of 'signup/index'; I think it's prettier :)
        FieldList::create(
            EmailField::create('Email', 'Email')
        ),
        FieldList::create(
            FormAction::create('submit', 'Submit')
                ->setAttribute('class', 'btn btn-success')
        ),
        RequiredFields::create('Email')
    );

    if($this->request->isPost()) 
        return $form; //return the form when it gets posted

    return $this->customise(array('Form'=>$form))->renderWith(array("Signup", "Page"));
}

自定义路由和处理表单提交
