经常会遇到需要调用多个指定的顶级栏目导航,那我们如何实现呢?关于DEDECMS实现嵌套获取栏目及其子栏目列表的问题,在论坛找到了以前版本的修改方法,于是修改了一下,现在分享给大家。请看实例代码:

织梦dedecms如何调用指定三级子栏目或多个栏目导航

修改文件:\include\taglib目录下的channel.lib.php,请将以下代码全部复制替换上述文件。

以下为引用的内容:

<?php

注:如果你安装的dedecms使用的表前缀进行修改过,需要把上面代码中的 dede_arctype 前缀修改掉才行。


模板调用 [field:sonchannel0] [/field:sonchannel0] 这个是用来取子栏目用得(使用[sonchannel+数字] 作为标签名是为了防止嵌套的时候无法正确解析标签)

这个的作用就是当你的栏目有很多子栏目 无限分级的时候方便你取子栏目的

例子

           {dede:channel type='son' typeid='22'}
              [field:typename/]
                    <ul>
                    [field:sonchannel0]
                    <li><a href="[field:typelink/]">[field:typename/]</a></li>
                         [field:sonchannel1]
                        <li><a href="[field:typelink/]">---[field:typename/]</a></li>
                             [field:sonchannel2]
                            <li><a href="[field:typelink/]">===[field:typename/]</a></li>
                                [field:sonchannel3]
                                <li><a href="[field:typelink/]">===[field:typename/]</a></li>
                                 [/field:sonchannel3]
                             [/field:sonchannel2]
                         [/field:sonchannel1]
                    [/field:sonchannel0]
                    </ul>
            {/dede:channel}
