$level = $lp['level'];

$down = $lp['down'];

if(!empty($down)) {

	$where['vod_down'] = [$down];
}

{maccms:vod num="6" type="current" down="2" order="desc" by="time"}
{$vo.vod_name}
{/maccms:vod}

{maccms:vod num="6" type="current"  order="desc" by="down"}
{$vo.vod_name}
{/maccms:vod}

增加一个扩展分类起名为zhuti

$param['class'] = htmlspecialchars(urldecode(trim($input['class'])));

在下面添加

$param['zhuti'] = htmlspecialchars(urldecode(trim($input['zhuti'])));

application/common/model/vod.php查找

$class = $lp['class'];

在其下面添加

$zhuti = $lp['zhuti'];

再次查找

if(!empty($param['class'])){
                $class = $param['class'];
}

在其大括号结束后面添加

if(!empty($param['zhuti'])){
                $zhuti = $param['zhuti'];
			}

再次查找

if(!empty($class))

注意有两处在其结束的大括号后面的第一处添加

if(!empty($zhuti)) {
                $where['vod_zhuti'] = ['like',mac_like_arr($zhuti), 'OR'];
                if (count($search_id_list_tmp = $vod_search->getResultIdList($zhuti, 'vod_zhuti', true)) <= $max_id_count) {
                    $search_id_list += $search_id_list_tmp;
                    unset($where['vod_zhuti']);
                }
            }

第二处添加

if(!empty($zhuti)) {
                $where['vod_zhuti'] = ['like',mac_like_arr($zhuti), 'OR'];
            }

打开application/common/validate/vod.php查找’vod_class’在本行下面另起一行添加

'vod_zhuti'          => 255,

打开application/admin/view/type/info.html找个位置添加

<div class="layui-form-item vod-list" {if condition="$info.type_mid neq '1'"} style="display:none" {/if}>
            <label class="layui-form-label">主题项目：</label>
            <div class="layui-input-block">
                <input type="text" class="layui-input" value="{$info.type_extend.zhuti}" placeholder="多个用,号分隔" name="type_extend[zhuti]">
            </div>
        </div>

这时就可以在后台－基础－分类管理 添加分类的时候填写了

打开application/admin/view/vod/info.html查找{:lang(‘class’)}在这一个区块DIV结束的后面添加

<div class="layui-form-item">
						<label class="layui-form-label">主题：</label>
						<div class="layui-input-inline w500"> 
                           <input type="text" class="layui-input" value="{$info.vod_zhuti}" placeholder="" id="vod_zhuti" name="vod_zhuti">
						</div>
						<div class="layui-input-inline w500 vod_zhuti_label">      
						</div>
					</div>

查找

$id == 'vod_keywords'

在其后面添加

 || $id == 'vod_zhuti'

得到如下代码

if($id == 'vod_class' || $id == 'vod_keywords' || $id == 'vod_zhuti')

至此结束示例：

搜索" {$param.wd}{$param.actor}{$param.director}{$param.area}{$param.lang}{$param.year}{$param.class}{$param.zhuti}”的结果如下

{:lang('en')}

在下面把value的值改为

{if condition="$info.vod_en eq ''"}0{else}{$info.vod_en}{/if}

这里是新建内容的时候自动把拼音写成0或者是更干脆的一招打开application/common/model/vod.php查找

if(empty($data['vod_en']))

把大括号里面的函数注释掉如下即可：

if(empty($data['vod_en'])){
            //$data['vod_en'] = Pinyin::get($data['vod_name']);
        }
