如何回显mysql数据库中的树枝标签

Question

我的数据库中有一些帖子。我有 Twig 模板。现在，我用 Twig 和 {% for post in posts .. {{ post.story }} .. endfor %} 回应所有帖子。 但是，如何回显已经在我的数据库中的标签？例如：

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

它被渲染为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'],

如果我理解您的问题，您的数据库中有一个 twig 格式的字符串，并且您想使用 twig 引擎呈现它。

为此，您可以使用include 或embed twig 函数。 创建一个获取帖子参数并将其包含在您的帖子模板中的单帖子模板。

包括一个帖子模板

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

或按照@DarkBee 的建议使用template_from_string
