Silverstripe 自定义前端表单未呈现

Silverstripe custom front end form is not rendering

我正在学习 SilverStripe 并创建自定义前端文件。但是我无法在视图中呈现表单。

这是我的ArticlePageController.php

class ArticlePageController extends PageController
{
    private static $allowed_actions = [
        'CommentForm'
    ];

    public function CommentForm()
    {
        $form = Form::create(
            $this,
            __FUNCTION__,
            FieldList::create(
                TextField::create('Name', '')->setAttribute('placeholder', 'Name*'),
                EmailField::create('Email', '')->setAttribute('placeholder', 'Email*'),
                TextareaField::create('Comment', '')->setAttribute('placeholder', 'Comment*')
            ),
            FieldList::create(
                FormAction::create('handleComment', 'Post Comment')
            ),
            RequiredFields::create('Name', 'Email', 'Comment')
        );

        return $form;
    }

    public function handleComment($data, $form)
    {
        $comment = ArticleComment::create();
        $comment->ArticlePageID = $this->ID;
        $form->saveInfo($comment);
        $comment->write();

        $form->sessionMessage('Thanks for your comment!', 'good');

        return $this->redirectBack();
    }
}

我在 ArticlePage.php

中添加了这个
private static $has_many = [
        'Comments' => ArticleComment::class,
    ];

这是ArticleComment.php

class ArticleComment extends DataObject
{
    private static $db = [
        'Name' => 'Varchar',
        'Email' => 'Varchar',
        'Comment' => 'Text'
    ];

    private static $has_one = [
        'ArticlePage' => ArticlePage::class,
    ];
}

在 ArticlePage.ss 中,我尝试按如下方式呈现表单。

<h1>Post Your Comment</h1>
<div>
$ContactForm
</div>

它没有呈现表单。如何呈现表单?

在您的 ArticlePage.ss 中,您正在调用 $ContactForm,但在您的控制器中,它被命名为 CommentForm,因此您应该调用它 - 这可能是问题所在...
