我们可以看一个示例标签：demotag.lib.php ，if(!defined('DEDEINC')) { exit("Request Error!"); } function lib_demotag(&$ctag,&$refObj) { global $dsql,$envs;$attlist="row|12,titlelen|24"; FillAttsDefault($ctag->CAttribute->Items,$attlist); extract($ctag->CAttribute->Items, EXTR_SKIP); $revalue = '';//------------------------------------------------------ $revalue = 'Hello Word!'; //------------------------------------------------------ return $revalue; } ?>我们会发现标签起作用了，输出了我们的内容。

$revalue = 'Hello Word!'; $revalue .=" Row:".$row.";TitleLen:".$titlelen;

这样我们可以看到，这个属性已经被创建变量并且赋值了。

接下来我们可以再进一步去修改这个标签。function lib_writerarc(&$ctag,&$refObj)接下来我们就可以编写查询语句及对底层模板处理的相关函数了$revalue = ''; $innertext = $ctag->GetInnerText(); $ctp = new DedeTagParse(); $ctp->SetNameSpace('field', '[', ']'); $sql = "SELECT * FROM dede_archives WHERE writer='{$refObj->Fields['writer']}' limit 0, $row";$dsql->Execute('me',$sql); while($rs = $dsql->GetArray('me')) {$rs['title'] = cn_substr($rs['title'], $titlelen);$ctp->LoadSource($innertext); foreach($ctp->CTags as $tagid=>$ctag) { if(!emptyempty($rs[strtolower($ctag->GetName())])) { $ctp->Assign($tagid,$rs[$ctag->GetName()]); } }$revalue .= $ctp->GetResult(); }最后返回这个值return $revalue;

整个文件内容如下：if(!defined('DEDEINC')) { exit("Request Error!"); } function lib_writerarc(&$ctag,&$refObj) { global $dsql,$envs;$attlist="row|12,titlelen|24"; FillAttsDefault($ctag->CAttribute->Items,$attlist); extract($ctag->CAttribute->Items, EXTR_SKIP); $revalue = ''; $innertext = $ctag->GetInnerText(); $ctp = new DedeTagParse(); $ctp->SetNameSpace('field', '[', ']'); $sql = "SELECT * FROM dede_archives WHERE writer='{$refObj->Fields['writer']}' limit 0, $row"; $dsql->Execute('me',$sql); while($rs = $dsql->GetArray('me')) {$rs['title'] = cn_substr($rs['title'], $titlelen);$ctp->LoadSource($innertext); foreach($ctp->CTags as $tagid=>$ctag) { if(!emptyempty($rs[strtolower($ctag->GetName())])) { $ctp->Assign($tagid,$rs[$ctag->GetName()]); } }$revalue .= $ctp->GetResult(); } return $revalue; } ?>通过动态浏览页面进行查看调试?aid=3{dede:writerarc row='10' titlelen='6'} [field:title/]{/dede:writerarc}以上就是织梦DEDECMS扩展标签怎么用的详细内容，更多请关注小潘博客其它相关文章！
