以下是报错代码，也是简单的if,就不能这么包含着写吗？
<if condition="$open_footer_menu_team">
<footer_menu_z></footer_menu_z>
<footer_menu_partner>
<a href="/im.php?pid={$DATA['team']['partner_id']}"><li class="wz hh"><i>会话</i></li></a>
<if condition="$login_user_id">
<a href="/ajax/collect.php?action=teamcollect&id={$id}" class="ajaxlink"><li class="wz sc"><i>收藏</i></li></a>
<else />
<a href="/login.php"><li class="wz sc"><i>收藏</i></li></a>
</if>
<a href="/order.php?id={$id}">
<li class="footer_team">
<de>
<s1>￥<s2>${moneyit($DATA['team']['team_all_price'])}</s2></s1>
<if condition="($DATA['team']['state']=='soldout' || $DATA['team']['close_time'] || $DATA['team']['audit']!='Y')">
<div class="r"><b>活动结束</b></div>
<else />
<if condition="$DATA['team']['deposit_bool']=='Y'">
<div class="r"><b><s5>支付定金</s5><s4>￥</s4>${moneyit($DATA['team']['team_price'])}</b></div>
<else />
<div class="r"><b>立即购买</b></div>
</if>
</if>
</de>
</li>
</a>
</footer_menu_partner>
</if>

这是修正后的写法，有时候很头晕.为什么必须这样写else_if<if  condition="$open_footer_menu_team">
<footer_menu_z></footer_menu_z>
<footer_menu_partner>
    <a href="/im.php?pid={$DATA['team']['partner_id']}"><li class="wz hh"><i>会话</i></li></a>
    <if  condition="$login_user_id">
    <a href="/ajax/collect.php?action=teamcollect&id={$id}" class="ajaxlink"><li class="wz sc"><i>收藏</i></li></a>
    <else />
    <a href="/login.php"><li class="wz sc"><i>收藏</i></li></a>
    </if>
    <a href="/order.php?id={$id}">
    <li class="footer_team">
            <de>
            <s1>￥<s2>${moneyit($DATA['team']['team_all_price'])}</s2></s1>
            <if  condition="($DATA['team']['state']=='soldout' || $DATA['team']['close_time'] || $DATA['team']['audit']!='Y')">
