thinkPHP 为什么if标签加上一个条件就不能使用了

Question

原来的：
<if condition="ACTION_NAME eq 'research' || ACTION_NAME eq 'build'">
<div class="index_box3">
                    <div class="title_box">
                        <div class="title_box_text">名师观点 | News</div>
                        <div class="title_box_moer"><a href="{gnwai:U('News/news',array('type'=>84))}"><img src="__PUBLIC__/User/images/more.png" /></a></div>
                        <div class="clear"></div>
                    </div>
                    <ul>

<volist name="news88" id="vo">
                        <li>
                            <span>{gnwai$vo.time}</span><a href="{gnwai:U('News/news_cont',array('type'=>$vo['typeId'],'id'=>$vo['id']))}">{gnwai$vo.theme}</a>
                        </li>
                   </volist>
                    </ul>
                    
                </div>
<else/>
<div class="index_box3">
                    <div class="title_box">
                        <div class="title_box_text">经管新闻 | News</div>
                        <div class="title_box_moer"><a href="{gnwai:U('News/news',array('type'=>84))}"><img src="__PUBLIC__/User/images/more.png" /></a></div>
                        <div class="clear"></div>
                    </div>
                    <ul>

<volist name="jgxw3" id="vo">
                        <li>
                            <span>{gnwai$vo.time}</span><a href="{gnwai:U('News/news_cont',array('type'=>$vo['typeId'],'id'=>$vo['id']))}">{gnwai$vo.theme}</a>
                        </li>
                   </volist>
                    </ul>
                    
                </div>
</if>
现在的：
<if condition="ACTION_NAME eq 'research' || ACTION_NAME eq 'build' || ACTION_NAME eq 'about'">
<div class="index_box3">
                    <div class="title_box">
                        <div class="title_box_text">名师观点 | News</div>
                        <div class="title_box_moer"><a href="{gnwai:U('News/news',array('type'=>84))}"><img src="__PUBLIC__/User/images/more.png" /></a></div>
                        <div class="clear"></div>
                    </div>
                    <ul>

<volist name="news88" id="vo">
                        <li>
                            <span>{gnwai$vo.time}</span><a href="{gnwai:U('News/news_cont',array('type'=>$vo['typeId'],'id'=>$vo['id']))}">{gnwai$vo.theme}</a>
                        </li>
                   </volist>
                    </ul>
                    
                </div>
<else/>
<div class="index_box3">
                    <div class="title_box">
                        <div class="title_box_text">经管新闻 | News</div>
                        <div class="title_box_moer"><a href="{gnwai:U('News/news',array('type'=>84))}"><img src="__PUBLIC__/User/images/more.png" /></a></div>
                        <div class="clear"></div>
                    </div>
                    <ul>

<volist name="jgxw3" id="vo">
                        <li>
                            <span>{gnwai$vo.time}</span><a href="{gnwai:U('News/news_cont',array('type'=>$vo['typeId'],'id'=>$vo['id']))}">{gnwai$vo.theme}</a>
                        </li>
                   </volist>
                    </ul>
                    
                </div>
</if>

Answer 1

换成这样试试
<if condition="in_array(ACTION_NAME,array('research','build','about'))">

Answer 2

嵌套php代码应该会快些。
