所以我把代碼備份一下:
<?php
# 獲取當前節點下的全部子孫節點
$catalog_grandson_nodes=array();
$cc=array($catalog_baseid);
for ($jibie=$catalog_gread+1;true;$jibie++){
$ki=sExplode(',',$cc);
$sql="select 編號,所屬父類 from 貼吧分類 where 級別=".$jibie." and 所屬父類 in (".$ki.")";
$rs=db_query($sql);
if (db_num($rs)<1) break; # 若已到了分支末端
$cc=array();
while ($row=db_eof($rs)){
$catalog_grandson_nodes[count($catalog_grandson_nodes)]=$row[0];
$cc[count($cc)]=$row[0];
}
}
$catalog_grandson_nodes_string=sExplode(",",$catalog_grandson_nodes);
if ($catalog_grandson_nodes_string=="") $catalog_grandson_nodes_string=$catalog_baseid;
?>
