Question

在drupal块中，您可以使用node_load（arg（1））访问节点变量。但是如何在一个区块中获得评论变量呢？

Answer 1

如果您需要获取节点的所有注释列表，可以使用以下代码：

$query = 'SELECT c.nid, c.subject, c.cid, c.timestamp FROM {comments} c INNER JOIN {node} n ON n.nid = c.nid WHERE c.nid = %d AND n.status = 1 AND c.status = %d ORDER BY c.cid DESC';

$result = db_query(arg(1), COMMENT_PUBLISHED);
while ($comment = db_fetch_object($result)) {
  $comments[] = $comment;
}

而不是仅使用arg(1)，而不考虑/node/<nid>/revision/<rid>等网址中的节点修订，您应该使用menu_get_object();在这种情况下，代码将成为：

$node = menu_get_object();
if (!empty($node) && !empty($node->nid)) {
  $query = 'SELECT c.nid, c.subject, c.cid, c.timestamp FROM {comments} c INNER JOIN {node} n ON n.nid = c.nid WHERE c.nid = %d AND n.status = 1 AND c.status = %d ORDER BY c.cid DESC';
  $result = db_query($query, $node->nid, COMMENT_PUBLISHED);
  while ($comment = db_fetch_object($result)) {
    $comments[] = $comment;
  }
}
