织梦dedecms 扩展channel栏目标签 获取交叉栏目名称和链接

channel栏目标签默认有调用顶级栏目(top)、子栏目(son)、同级栏目(self)，那想获取交叉栏目的名称和链接怎么获取呢？文章源自菜鸟学院-https://www.cainiaoxueyuan.com/cms/1718.html

其实在原来的代码上改一下就可以了。下面是具体代码。打开文件channel.lib.php：文章源自菜鸟学院-https://www.cainiaoxueyuan.com/cms/1718.html

在搜索：文章源自菜鸟学院-https://www.cainiaoxueyuan.com/cms/1718.html

$topid = $refObj->TypeLink->TypeInfos['topid'];

在其下方增加：文章源自菜鸟学院-https://www.cainiaoxueyuan.com/cms/1718.html

$crossid = $refObj->TypeLink->TypeInfos['crossid'];

再搜索：文章源自菜鸟学院-https://www.cainiaoxueyuan.com/cms/1718.html

$topid = $row2['topid'];

在其下方增加：文章源自菜鸟学院-https://www.cainiaoxueyuan.com/cms/1718.html

$crossid = $row2['crossid'];

然后再查找：文章源自菜鸟学院-https://www.cainiaoxueyuan.com/cms/1718.html

1     else if($type=='son')
2     {
3         if($typeid==0) return '';
4         $sql = "SELECT id,typename,typedir,isdefault,ispart,defaultname,namerule2,moresite,siteurl,sitepath
5           From `#@__arctype` WHERE reid='$typeid' And ishidden<>1 order by sortrank asc limit 0, $line ";
6     }

在下方增加：文章源自菜鸟学院-https://www.cainiaoxueyuan.com/cms/1718.html

1     else if($type=='cross')
2     {
3         if($typeid==0) return '';
4         $sql = "SELECT id,typename,typedir,isdefault,ispart,defaultname,namerule2,moresite,siteurl,sitepath,crossid
5           From `#@__arctype` WHERE id in ($crossid) And ishidden<>1 order by sortrank asc limit 0, $line ";
6     }

如此修改之后就可以在模板上使用了。文章源自菜鸟学院-https://www.cainiaoxueyuan.com/cms/1718.html
