Php 银条。SETFORMATION导致错误

我有一份报名表：

function SignupForm() { 

      $fields = new FieldSet( 
         new TextField("FirstName", "First name"), 
         new TextField("Surname"), 
         new EmailField("Email", "Email address") 
      );    
   $submitAction = new FieldSet(new FormAction("SignupAction", "Sign up")); 
   $required = new RequiredFields("Email"); 

      $SignupForm = new Form($this, "SignupForm", $fields, $submitAction, $required);



      return $SignupForm; 
   }

   function SignupAction($data, $form) {

      $member = new Member(); 
      $form->saveInto($member);

      $member->write(); 

      if($group = DataObject::get_one('Group', "ID = $this->defaultGroupID")){ 
         $member->Groups()->add($group); 
         Director::redirect('thanks-for-registering/'); 
      }else{ 
         Director::redirect('registration-failed/'); 
      }

   }

它在主页上运行良好，但是它出现在网站的每个页面和子页面上，所以我需要设置表单操作

我尝试添加以下内容：

$SignupForm->setFormAction(Director::baseURL().'home/SignupAction');

在返回$SignupForm之前，当我提交表单时（从任何地方）出现以下错误

这是怎么回事

谢谢

发生此错误是因为silverstripe处理表单的方式

silverstripe从不重定向到表单操作，它总是重定向到表单本身，因此如果您的表单

function SignupForm() {
   ...
   return new Form(...);
}

然后silverstripe将始终重定向回该函数，因此如果您在mysite.com/foobar/上，表单将转到mysite.com/foobar/SignupForm 然后，它将调用->SignupAction（），因此SignupAction永远不会出现在url中

我会这样做：

<?php

class Page extends SiteTree {
}

class Page_Controller extends ContentController {
    public static $allowed_actions = array(
        'SignupForm',
        'registeringThanks',
        'registrationFailed',
    );
    public function SignupForm() {
        $fields = new FieldSet(
            new TextField("FirstName", "First name"),
            new TextField("Surname"),
            new EmailField("Email", "Email address")
        );
        $actions = new FieldSet(
            new FormAction("SignupAction", "Sign up")
        );
        $validator = new RequiredFields("Email");
        // use __FUNCTION__ here so we don't have to type SignupForm again
        return new Form($this, __FUNCTION__, $fields, $actions, $validator);
    }
    public function SignupAction($data, Form $form, SS_HTTPRequest $request) {
        $member = new Member();
        $form->saveInto($member);
        $member->write();
        $home = SiteTree::get_by_link(null);
        // instead of using $group = DataObject::get_one('Group', "ID = {$home->defaultGroupID}");
        // we can just use $group = $home->defaultGroup(); if defaultGroup is a has_one relation
        if ($home && $home->defaultGroup()) {
            $member->Groups()->add($home->defaultGroup());
            $this->redirect('registeringThanks/');
        } else {
            $this->redirect('registrationFailed/');
        }
    }
    public function registeringThanks(SS_HTTPRequest $request) {
        // display the same page again, but overwrite the Title and Content
        return $this->customise(array(
            'Title' => 'Thank you!',
            'Content' => 'All sorts of spam mails are on there way to you',
        ));
    }
    public function registrationFailed(SS_HTTPRequest $request) {
        // display the same page again, but overwrite the Title and Content
        return $this->customise(array(
            'Title' => 'Great, ... you broke it!',
            'Content' => 'Sorry, we can\'t send you any spam because something went wrong',
        ));
    }
}

仅作澄清：您已经将上述表单和表单处理程序添加到Page类中，因为您希望在每个页面上都使用它，对吗？但是，为什么要重定向处理程序，您应该在每个页面上都有可用的处理程序？
<?php
