phpcms 替换超过五条数据时的取法

在 标题 关键词 来源 摘要 内容 中 可同时填入两条数据 用 | 隔开

如图：

 {pc:content  action="lists" catid="67" order="id ASC" num="2" moreinfo="1"}
             {loop $data $key $val}
             
             <div class="blog-post">
					<h4><a href="single.html">{php $title = explode('|', $val[title])}
                    {$title[0]}</a></h4>
					<div class="post-details">
						<p>{php $keywords = explode('|', $val[keywords])}
                    {$keywords[0]}
                     <a href="#">{php $keywords = explode('|', $val[keywords])}
                     {$keywords[1]}</a>
                     {php list($copyfrom) = explode('|', $val['copyfrom'])}
                    {$copyfrom}
                    <a href="#">{php $description = explode('|', $val[description])}
                    {$description[0]}</a> 
                     {php $description = explode('|', $val[description])}
                    {$description[1]}
                     </p>
					</div>
					<a href="single.html"><img src="{$val[thumb]}" alt="" /></a>
					<p>{php $content = explode('|', $val[content])}
                    {$content[0]}</p>
					<p>{php $content = explode('|', $val[content])}
                    {$content[1]}</p>
					<a class="hvr-shutter-in-vertical button more" href="{$val[url]}">{php $title = explode('|', $val[title])}
                    {$title[1]}</a>
				</div>
                
             {/loop}
            {/pc}

　　用explode 分割取索引 就好了
