Question

我只是学习Twig模板，我无法弄清楚如何加载当前主题目录之外的目录中的模板部分，以便其他主题可以重用它们。

我首先只是简单地加载位于core / tpls /目录中的head.html模板部分。使用我尝试的variouse方法，我得到以下错误：

PHP致命错误：带有消息的未捕获异常'Twig_Error_Loader' '无法找到模板“/home/ubuntu/workspace/core/tpls/head.html” （查看：/ home / ubuntu / workspace / themes / core）在“base.html”中第5行。

文件位于目录中，路径正确，尽管日志错误另有说明。

位于themes / core /目录中的我的base.html包含自定义Twig函数，以包含位于主题目录之外的head.html模板：

<html lang="en" class="no-js">
<head>

    {% include core.head %} // This is line 5 and throws the error and need to work correctly
    // {% include core_head %} // This throws the error and should function the same as {% include core_head %}
    // {% include tpl.head %} <-- If I use this, my function for grabbing templates from the theme works since I have a copy of the head.html in the theme dir too //

</head>
<body>

<header id="header">

    {% include tpl.header %} // This works via the get_tpl() function

</header>

    {% include tpl.breadcrumbs %} // This works too

[. . .]

我讨厌整个班级混乱，但有人看到我错了可能会有所帮助。 get_core_tpl（）函数是我无法工作的地方，我的其他get _ *（）函数可以正常工作。在那里查看我的评论，并注意我在befor_rendor（）函数中的注释：

<?php

class Get_TPLs {

    private $tpl_name,
            $theme = 'core',
            $tpl_array = array(
                'breadcrumbs',
                'content',
                'cover',
                'footer',
                'head',
                'header',
                'sidebar'
    );

    public function before_load_content(&$file) {
        $this->tpl_name = basename($file, '.md');
    }

    public function config_loaded(&$settings) {

        if (isset($settings['core_tpl']))
            $this->core_tpl = $settings['core_tpl'];

        if (isset($settings['tpl_array']))
            $this->tpl_array = $settings['tpl_array'];

        if (isset($settings['theme']))
            $this->theme = THEMES_DIR . $settings['theme'];
    }

    public function file_meta(&$meta) {

        $config = $meta;
        if (isset($config['slug'])):
            $this->tpl_name = strtolower($config['slug']);
        endif;
    }

    public function before_render(&$twig_vars, &$twig) {

 //// ==== THIS IS CALLED WITH {% include core.[TEMPLATE_NAME] %} SEE Base.html ==== ////

        // core/tpl/file
        $twig_vars['core'] = $this->get_core_tpl();

//// === THIS IS A SIMPLIFIED VERSION OF THE ABOVE VAR - IT'S CALLED WITH {% include core_head %} but It throws the same error ==== ////

        $twig_vars['core_head'] = CORE_TPL . '/head.html';

        // theme/tpl/file
