首先，用下面这些代码替换掉phpcms/libs/functions/extention.func.php的内容

然后，内容——模型管理——选择一个模型添加新字段，如图。
最后，在要调用产品筛选的栏目模板页添加标签 ，如下。
<span>性别：</span>{loopfilters('xingbie',$modelid)$r}{$r[menu]}{/loop}
{php$sql=structure_filters_sql($modelid)}{php$urlrule=makeurlrule()}{pc:contentaction="lists"where="$sql"catid="$catid"num="10"order="idDESC"page="$page"urlrule="$urlrule"}<ulclass="photo-listpicbig">{loop$data$r}<li><divclass="img-wrap"><ahref="{$r[url]}"><imgsrc="{thumb($r[thumb],150,112)}"width="150"height="112"alt="{$r[ ]}"/></a></div><spanstyle="color:{$r[style]}">{str_cut($r[ ],28)}</span></li>{/loop}</ul><divid="pages"class="text-c">{$pages}</div>{/pc}
