DEDEcms联动类别一般都是两级联动，怎么把这个两级的修改成一级的呢？我跟大家分享下现实方法：

1.首先要修改infolink.lib.php
注释掉一下代码：

/*
$sontype = ( ($househx % 500 != 0) ? $househx : 0 );
$toptype = ( ($househx % 500 == 0) ? $househx : ( $househx-($membertype%500) ) );
$fields['househx'] = "<a href='{$baseurl}plus/list.php?channelid={$channelid}&tid={$typeid}&househx={$toptype}&nativeplace={$nativeplace}'><b>{$em_househxs[$toptype]}</b></a> ";

下级显示不显示
foreach($em_househxs as $eid=>$em)
{
if($eid < $toptype+1 || $eid > $toptype+499) continue;
if($eid == $househx) {
$fields['househx'] .= " <b>{$em}</b>";
}
else {
$fields['househx'] .= " <a href='{$baseurl}plus/list.php?channelid={$channelid}&tid={$typeid}&househx={$eid}&nativeplace={$nativeplace}'>{$em}</a>";
}
}
*/

换成

foreach($em_househxs as $eid=>$em)
{
if($eid % 500 != 0) continue;
if(isset($_GET['househx']))
{
$navclass=$_GET['househx'];
if ($navclass==$eid)
{
$navclass=' style=color:#ff0000';
}
$fields['househx'] .= " <a href='{$baseurl}plus/list.php?channelid={$channelid}&tid={$typeid}&househx={$eid}&nativeplace={$nativeplace}'".$navclass.">{$em}</a>";
}
}
