nested - Mustache.php 中的嵌套标签

Question

我正在使用 Mustache for php 来呈现我的网页。我一直在github上的 dev-branch 中玩代码，发现了一些有趣的操作方法。例如，我知道可以通过为它们定义一个辅助函数来动态加载部分。然而，我似乎找不到的是一种像这样进行嵌套标签的方法：

{{article.{{page.name}}}}

在某种辅助函数或高阶函数的帮助下，这是否可能？

You can use Lambdas to achieve something similar. Quoting from Mustache.php's wiki:

When the value is callable — such as an anonymous function — the callable will be invoked and passed the block of text.

So, in your mustache template, the following:

{{#article_field}}{{page.name}}{{/article_field}}

With a View Class like this:

class View_Page {

    public $_article;

    public function article_field()
    {
        return function($string)
        {
            return $this->_article[$string];
        }
    }
}

Will output the article field whose name resides in the page.name property's value.

Head over to Mustache.php's official wiki to read more about Lambdas and callables.
