Question

我的数据库中有一些帖子。我有Twig模板。现在，我回复了Twig和{% for post in posts .. {{ post.story }} .. endfor %}的所有帖子。 但是，如何回显已存在于我的数据库中的标签？例如：

My long story {{ post_image.1 }} is about...

它呈现为My long story {{ post_image.1 }} is about...，没有任何变化。

        $posts = $sql->query("SELECT * FROM posts, posts_assets, posts_meta, users WHERE posts.id = posts_assets.id_post AND posts.id_byurl = posts_assets.id_byurl AND posts.id = posts_meta.id_post AND posts.id_byurl = posts_meta.id_byurl AND posts.pub_author = users.id ORDER BY posts.id_bytime DESC LIMIT 3");

        $tags = $sql->query("SELECT * FROM tags");

        //posts.id, posts.id_bytime, posts.id_byurl, posts.pub_time, posts.pub_title, posts.pub_author, posts.pub_tags, posts.pub_story, posts_assets.id_post, posts_assets.id_byurl, posts_assets.images

        try {
            //$loader = new Twig_Loader_Filesystem('theme/views');
            $loader = new Twig_Loader_Filesystem($aeConfig->site()['theme'] . $aeConfig->site()['theme_views']);
            $twig = new Twig_Environment($loader);
            $template = $twig->loadTemplate('index.tpl');

            if ($user->isAuth()) {
                echo $template->render(array(
                    'title' => $aeConfig->site()['title'],
                    'theme_dir_static' => $aeConfig->site()['theme'] . $aeConfig->site()['theme_static'],
                    'posts' => $posts,
                    'tags' => $tags,

                ));
            } else {
                echo $template->render(array(
                    'title' => $aeConfig->site()['title'],

        } catch (Exception $e) {
            die ('Error: ' . $e->getMessage());
        }
    }

    Flight::route('/', 'index');

如果我理解了你的问题，你的数据库中有一个twig格式的字符串，你想用树枝引擎渲染它。

要执行此操作，您可以使用include或embed枝条功能。创建一个单一帖子模板，获取帖子参数并将其包含在您的帖子模板中。

包含帖子模板

{% for post in posts .. {% include 'post.html' with {'post': post} %}  .. endfor %}

或使用template_from_string作为@DarkBee建议
