PHP Mustache 2.1部分加载不是基于文件名 [英] PHP Mustache 2.1 partial loading NOT based on the filename

问题描述

是否有一种基于文件名值数组加载部分的方法?

Is there a way to load partials based on an array of filename values?

当前，如果我编写此{{> sidebar}}，它将查找views/sidebar.mustache. (基于模板加载程序类，我可以在其中指定在何处查找模板)

Currently if I write this {{> sidebar}} it will look for views/sidebar.mustache. (based on the template loader class where I can specify where to look for the templates)

理想情况下，我希望{{> sidebar}}是变量名而不是文件名.

Ideally I want that {{> sidebar}} would be a variable name and not a file name.

如果要传递给加载程序，我想实现的是不基于文件名查找侧边栏部分:

What I want to achieve is to look for the sidebar partial not based on the filename, if I pass to the loader:

$partials = array(
    'sidebar' => 'folder1/somefile'
);

将会翻译为:views/folder1/somefile.mustache.

推荐答案

您可以通过添加新的partials loader实现轻松地做到这一点.您可以制作一个别名加载器"，用于存储那些模板引用:

You can easily do this by adding a new partials loader implementation. You could make an "alias loader", which stores those template references:

class FilesystemAliasLoader extends Mustache_Loader_FilesystemLoader implements Mustache_Loader_MutableLoader
{
    private $aliases = array();

    public function __construct($baseDir, array $aliases = array())
    {
        parent::__construct($baseDir);
        $this->setTemplates($aliases);
    }

    public function load($name)
    {
        if (!isset($this->aliases[$name])) {
            throw new Mustache_Exception_UnknownTemplateException($name);
        }

        return parent::load($this->aliases[$name]);
    }

    public function setTemplates(array $templates)
    {
        $this->aliases = $templates;
    }

    public function setTemplate($name, $template)
    {
        $this->aliases[$name] = $template;
    }
}

然后，您将其设置为partials loader:

Then, you would set that as the partials loader:

$partials = array(
    'sidebar' => 'folder1/somefile'
);

$mustache = new Mustache_Engine(array(
    'loader'          => new Mustache_Loader_FilesystemLoader('path/to/templates'),
    'partials_loader' => new FilesystemAliasLoader('path/to/partials'),
    'partials'        => $partials,
));

...或者您可以将别名传递给加载器构造函数，或者甚至可以稍后在加载器或引擎实例上设置它们:

... or you could pass the aliases to the loader constructor, or you could even set them later on the loader or engine instance:

$loader = new FilesystemAliasLoader('path/to/partials', $partials);
$loader->setTemplates($partials);
$mustache->setPartials($partials);
