帝国cms导航栏目利用灵动标签实现当前栏目高亮效果

　　具有子栏目的导航效果:

<ul>
	<li class="menu-item menu-item-type-custom <?php if($GLOBALS[navclassid]==""){echo 'current-menu-item';
} ?> menu-item-object-custom menu-item-home"><a href="[!--news.url--]">首页</a></li>
	[e:loop={"select classid,classname,sonclass from {$dbtbpre}enewsclass where bclassid=0 order by myorder,classid
	asc",0,24,0}]
	<li class="menu-item menu-item-type-custom menu-item-object-custom 
<?php 
if($bqr[classid]==1){
    $classurl='#';
}else{
    $classurl=sys_ReturnBqClassname($bqr,9);//取得栏目地址 
}
$GLOBALS[navclassid]=$GLOBALS[navclassid]?$GLOBALS[navclassid]:0;
if($GLOBALS[navclassid])
{
$fcr=explode('|',$class_r[$GLOBALS[navclassid]][featherclass]);
$topbclassid=$fcr[1]?$fcr[1]:$GLOBALS[navclassid];//取得当前栏目的一级栏目ID
}
if($bqr[classid]==$topbclassid||$bqr[classid]==$GLOBALS[navclassid])
{
echo 'current-menu-item';
}
if(!empty($bqr[sonclass])){
    echo 'menu-item-has-children';
}
?>"><a href="<?=$classurl?>"><?=$bqr[classname]?></a>
		<?php if(!empty($bqr[sonclass])){ ?>
		<ul class="sub-menu">
			[showclasstemp]$bqr[classid],1,0,0[/showclasstemp]
		</ul>
		<?php } ?>
	</li>
	[/e:loop]
</ul>

　　实现一级栏目的导航效果:

<ul>
	<li><a href="[!--news.url--]" <?php if($GLOBALS[navclassid]==""){echo 'id="nav_default"';
} ?>>首页</a></li>
	[e:loop={"select classid,classname from {$dbtbpre}enewsclass where bclassid=0 order by myorder,classid asc",0,24,0}]
	<?php $classurl=sys_ReturnBqClassname($bqr,9);//取得栏目地址  ?>
	<li><a href="<?=$classurl?>"
			<?php if($bqr[classid]==$GLOBALS[navclassid]){echo 'id="nav_default"';} ?>><?=$bqr[classname]?></a></li>
	[/e:loop]
</ul>
