加載塊中的註釋變量

Question

在drupal塊中，可以使用node_load（arg（1））訪問節點變量。但是如何在塊中獲得註釋變量？

Answer 1

如果你需要得到的一個節點上的所有評論列表，你可以使用下面的代碼：

$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; 
} 

而並非只是使用arg(1)，這將不考慮節點修訂像URL /node/<nid>/revision/<rid>，您應該使用menu_get_object();在這種情況下代碼將變爲：

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