DEDE有无缩略图如何调取

同一样式分开调取

[field:array runphp='yes']@me = (strpos(@me['litpic'],'defaultpic') ? "":"<a href='{@me['arcurl']}' class='part3L'><img src='{@me['litpic']}' alt='{@me['title']}'/></a>");         　     　[/field:array]

用不同样式分开调取
有图的置顶，只显示一条
{dede:arclist flag="p" row="1" titlelen="20"}
<img src="[field:litpic/]">[field:description/]
{/dede:arclist}
没图的
{dede:arclist  row="6" titlelen="40" noflag='p'}
<a href="[feild:arcurl/]">[field:title/]</a>
{/dede:arclist}
