經(jīng)過蕭涵的努力，百度+GOOGLE+自己腦袋，終于搞定了這個(gè)東西，不敢獨(dú)享，發(fā)出來給有需要的朋友分享。

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(shí)，把DEDE自動(dòng)內(nèi)鏈和URL全拼格式搞定后，又遇到了個(gè)小問題，因?yàn)楫a(chǎn)品分類最多有四級(jí)，客戶要求在左側(cè)有個(gè)彈出式菜單調(diào)用各級(jí)子分類出來，而DEDECMS默認(rèn)只能調(diào)用一級(jí)分類。經(jīng)過蕭涵的努力，百度+GOOGLE+自己腦袋，終于搞定了這個(gè)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:

在模板里面用 [field:sonchannel0] [/field:sonchannel0] 調(diào)用，這個(gè)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(shí)候無法正確解析標(biāo)簽），這個(gè)的作用就是當(dāng)你的欄目有很多子欄目無限分級(jí)的時(shí)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(cuò)修改文件前請(qǐng)做好備份，以上代碼可能有些引號(hào)又被自動(dòng)轉(zhuǎn)成全角的了，請(qǐng)修改成半角的，或者可以找蕭涵索取此修改后的文件。
