phpcms文章若何挑选分类
phpcms文章挑选分类的办法：
起首，用上面这些代码交换掉phpcms/libs/functions/extention.func.php的内容

?>而后，内容——模子治理——抉择一个模子增加新字段，如图。
最初，正在要挪用产物挑选的栏目模板页增加标签 ，以下。
<span>性别：</span>
{loop filters('xingbie',$modelid) $r}
{$r[menu]}
{/loop}{php $sql = structure_filters_sql($modelid)}
{php $urlrule = makeurlrule()}
{pc:content action="lists" where="$sql" catid="$catid" num="10" order="id DESC" page="$page" urlrule="$urlrule"}
<ul class="photo-list picbig">
{loop $data $r}
<li>
<div class="img-wrap">
<a href="{$r[url]}"><img src="{thumb($r[thumb],150,112)}" width="150" height="112" alt="{$r[title]}"/></a>
</div>
<span style="color:{$r[style]}">{str_cut($r[title],28)}</span>
</li>
{/loop}
</ul>
<div id="pages" class="text-c">{$pages}</div>
