问题描述

我想根据它的评论ID在drupal打印一个单独的评论。我该怎么做？ Google和其他来源没有让我失望。谢谢。

I want to print a individual comment in drupal based on it's comment ID. How can I do this? Google and other sources have yielded me nothing. Thank you.

推荐答案

伊顿的建议很好（除了 {comments} 如果您需要像核心一样显示评论，包括来自节点的信息，则 {comment} ）。除了 modules / comment / comment.tpl.php 中的默认theme_comment实现不使用$ node。

Eaton's suggestion is good (except it's {comments}, not {comment}) if you need to display the comment like core does it, including the info coming from the node. Except the default theme_comment implementation in modules/comment/comment.tpl.php makes no use of $node.

但是，我做的略有不同，因为如果你需要提取一个注释，用 comment.tpl.php 提供的正常内容格式显示它可能会不适用

However, I'd do it slightly differently, because if you need to extract a single comment, displaying it with the normal content formatting provided by comment.tpl.php is likely to be inappropriate.

function print_comment($cid) {
  $sql = "SELECT * FROM {comment} c WHERE c.cid = %d";
  if ($comment = db_fetch_object(db_rewrite_sql(db_query($sql, $cid), 'c'))) {
    return theme('my_special_comment_formatting', $comment);
  }
}

当然，定义这个特殊的commment格式在你的模块的 hook_theme（）实现，灵感来自于什么 comment.tpl.php 。

And of course, define this special commment formatting in your module's hook_theme() implementation, inspired by what comment.tpl.php does.

2014-02更新：请注意，这是一个2009年的问题/答案。在Drupal 8中，您只是不想访问假设的底层SQL数据库（并且不会这样做，而是使用DBTNG），但只需使用以下内容：

2014-02 UPDATE: note that this is a 2009 question/answer. In Drupal 8, you just don't want to access the hypothetical underlying SQL database (and would not do it like this anyway, but use DBTNG), but just use something like:

if ($comment = entity_load('comment', $cid)) {
  return entity_view($comment, $view_mode);
}
