做企業(yè)網(wǎng)站大部分是使用DEDECMS，今天在給客戶設(shè)計(jì)網(wǎng)站時，把DEDE自動內(nèi)鏈和URL全拼格式搞定后，又遇到了個小問題，因?yàn)楫a(chǎn)品分類最多有四級，客戶要求在左側(cè)有個彈出式菜單調(diào)用各級子分類出來，而DEDECMS默認(rèn)只能調(diào)用一級分類。經(jīng)過蕭涵的努力，百度+GOOGLE+自己腦袋，終于搞定了這個東西，不敢獨(dú)享，發(fā)出來給有需要的朋友分享。

首先要把/include/taglib/channerl.lib.php 文件的代碼修改成以下的：

代碼如下:
<?php
function lib_channel(&$ctag,&$refObj)

extract($ctag->CAttribute->Items, EXTR_SKIP);
$innertext = $ctag->GetInnerText();
if(empty($typeid) && $envs['typeid']!=0)
{
$typeid = $envs['typeid'];
$reid = $envs['reid'];
}else{
$reid=0;
}
if($type==”||$type==’sun’) $type=”son”;
if($innertext==”) $innertext = GetSysTemplets(“channel_list.htm”);
if($reid==0 && $typeid>0)
{
$dbrow = $dsql->GetOne(“Select reid From ying_arctype where id=’$typeid’ “);
if(is_array($dbrow)) $reid = $dbrow['reid'];
}
$likeType = ”;

$likeType .= $linkOkstr;

}else
{

在模板里面用 [field:sonchannel0] [/field:sonchannel0] 調(diào)用，這個是用來取子欄目用得（使用【sonchannel+數(shù)字】作為標(biāo)簽名是為了防止嵌套的時候無法正確解析標(biāo)簽），這個的作用就是當(dāng)你的欄目有很多子欄目無限分級的時候方便你取子欄目的。實(shí)例一下：

代碼如下:
<ul id="left_nav">
{dede:channel type='son' typeid='16'}
<li><a href="[field:typelink/]“>[field:typename/]</a>
<ul>
[field:sonchannel0]
<li><a href="[field:typelink/]“>[field:typename/]</a>
<ul>
[field:sonchannel1]
<li><a href="[field:typelink/]“>[field:typename/]</a>
<ul>
[field:sonchannel2]
<li><a href="[field:typelink/]“>[field:typename/]</a>
<ul>
[field:sonchannel3]
<li><a href="[field:typelink/]“>[field:typename/]</a></li>
[/field:sonchannel3]
</ul>
</li>
[/field:sonchannel2]
</ul>
</li>
[/field:sonchannel1]
</ul>
</li>
[/field:sonchannel0]
</ul>
</li>
{/dede:channel}
</ul>

以上typeid中的數(shù)字改成你的大分類的ID即可，因?yàn)樵贒EDE官方論壇沒找到，所以這里發(fā)上來，希望能方便有用者。（轉(zhuǎn)自蕭涵的博百優(yōu)）

注意：未免出錯修改文件前請做好備份，以上代碼可能有些引號又被自動轉(zhuǎn)成全角的了，請修改成半角的，或者可以找蕭涵索取此修改后的文件。
