加载块中的注释变量

Question

在drupal块中，可以使用node_load（arg（1））访问节点变量。但是如何在块中获得注释变量？

Answer 1

如果你需要得到的一个节点上的所有评论列表，你可以使用下面的代码：

$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; 
} 

而并非只是使用arg(1)，这将不考虑节点修订像URL /node/<nid>/revision/<rid>，您应该使用menu_get_object();在这种情况下代码将变为：

$node = menu_get_object(); 
if (!empty($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; 
    } 
}
