在我安装了 XAMPP 服务器之后，我想在我的服务器上安装 cakephp。到目前为止一切正常。我已经生成了在 cakephp 教程中的初学者教程中解释的脚手架代码

但是，现在是我检索带有特定标签的书签的时候了，我正在一步一步地遵循代码，但是当我尝试通过其 URL 调用它时它没有显示标签。它一直告诉我模板丢失。它说标签 .ctp 文件尚未创建。

这让我很恼火，因为我一遍又一遍地检查代码，看看我是否遗漏了什么，但什么也没有。谢谢你。

这是 BookmarkController 的代码

/**

        // the passed URL path segments in the request.
        $tags = $this->request->params['pass'];

        // Use the BookmarksTable to find tagged bookmarks.
        $bookmarks = $this->Bookmarks->find('tagged', [
            'tags' => $tags
        ]);

        // Pass variables into the view template context.
        $this->set([

我相信您还没有完成教程指导您创建文件的部分src/Template/Bookmarks/tags.ctp。

现在，如果您访问该/bookmarks/taggedURL，CakePHP 将显示一个错误，让您知道您还没有创建视图文件。接下来，让我们为我们的tags()操作构建视图文件。放入src/Template/Bookmarks/tags.ctp以下内容：

<h1>
    Bookmarks tagged with
    <?= $this->Text->toList($tags) ?>
</h1>

<section>
    <?php foreach ($bookmarks as $bookmark): ?>
        <article>
            <!-- Use the HtmlHelper to create a link -->
            <h4><?= $this->Html->link($bookmark->title, $bookmark->url) ?></h4>
            <small><?= h($bookmark->url) ?></small>

            <!-- Use the TextHelper to format text -->
            <?= $this->Text->autoParagraph($bookmark->description) ?>
        </article>
    <?php endforeach; ?>
</section>

请参阅Cookbook 3.x：书签教程：创建视图。

我不确定我做了什么，但我只是重新做了练习，重新复制了代码，它成功了！看来我第一次犯了错误。

多谢你们。
