方法一：
打开include/extend.func.php页面底部加入
function GetAddField($aid,$addField)
{
global $dsql;
$row = $dsql->GetOne("SELECT c.addtable FROM #@__archives AS a LEFT JOIN #@__channeltype AS c ON a.channel=c.id where a.id='$aid'");
$addtable = trim($row['addtable']);
$row = $dsql->GetOne("SELECT $addField FROM `$addtable` WHERE aid=$aid");
return $row["$addField"];
}search.htm 搜索结果页模板调用标签
[field:id function=GetAddField(@me,"自定义字段名")/]
方法二：
[field:id runphp=yes]global $dsql;$row = $dsql->GetOne("SELECT c.addtable FROM #@__archives AS a LEFT JOIN #@__channeltype AS c ON a.channel=c.id where a.id=@me");$result = $dsql->GetOne("SELECT body FROM `$row[addtable]` WHERE aid=@me");@me = cn_substr(html2text($result['body']),500);[/field:id]body换成你自己的自定义字段
