**织梦DEDECMS扩展标签怎么用？**

织梦DEDECMS扩展标签演示实例

推荐学习：织梦cms

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}
