文章列表,栏目列表调用自定义字段时，如何调用呢？
{eyou:arclist titlelen='20' infolen='50' row='4' addfields='自定义字段名'}
{eyou:arclist titlelen='20' infolen='50' row='4' addfields='自定义字段名'}
<li >
<div class="news-com"><img src="{$field.litpic}">
<div class="news-h"><a href="{$field.arcurl}" target="_blank" title="{$field.title}">{$field.title}</a></div>
<div class="news-sum">{$field.自定义字段名}...</div>
</div>
</li>
{/eyou:arclist}
{/eyou:arclist}
