dedecms织梦让likearticle的mytypeid支持多个栏目和子栏目
在使用dede:likearticle时，如果你想获取多个指定栏目下的相关文章，而刚好这个多个栏目下还有子栏目时，官方的程序不能满足你的需求，你需要改一下
打开 \include\taglib\likearticle.lib.php 找到
<span style="font-family:tahoma,geneva,sans-serif;"><span style="font-size:14px;">if( !empty($typeid) && !preg_match('#,#', $typeid) ) {
$typeid = GetSonIds($typeid);
}</span></span>
在它下面加入
<span style="font-family:tahoma,geneva,sans-serif;"><span style="font-size:14px;">else
{
$typeids = explode(',', $typeid);
foreach($typeids as $ttid) {
$typeidss[] = GetSonIds($ttid);
}
$typeidStr = join(',', $typeidss);
$typeidss = explode(',', $typeidStr);
$typeidssok = array_unique($typeidss);
$typeid = join(',', $typeidssok);
}
</span></span>
