zdcms搜索参数多条件筛选的写法
类似以上图片这种条件搜索，一个字段可以使用多个条件选中查询，此查询需要以下字段支持：
联动菜单：Linkage 联动菜单多选：Linkages 复选框：Checkbox 单选按钮：Radio 下拉选择：Select
搜索条件写法：
<div class="form-group row">
<label class="col-md-2 control-label">单选字段-多条件</label>
<div class="col-md-10">
<label><a class="label {if !$params.danxuananniu}label-success{else}label-default{/if}" href="{Router::search_url($params, 'danxuananniu', NULL)}">不限</a></label>
<!--调用单选字段数据方法-->
{php $field = dr_field_options($ci->module['field']['danxuananniu']['id']);}
{loop $field $value $name}
<label><a class="label {if dr_is_double_search($params.danxuananniu, $value)}label-success{else}label-default{/if}" href="{Router::search_url($params, 'danxuananniu', dr_get_double_search($params.danxuananniu, $value))}">{$name}</a></label>
{/loop}
</div>
</div>判断是否选择：
{if dr_is_double_search($params.字段名称, "当前值")} 选中了 {/if}传入值写法：
{Router::search_url($params, '字段名称', dr_get_double_search($params.字段名称, "当前值"))}搜索值写法原理：
关键字A|关键字B
多个条件已 | 符号分开
具体可参考zdcms自带的demo模块搜索中已经提供的示例，如下：
<div class="form-group row">
<label class="col-md-2 control-label">栏目分类</label>
<div class="col-md-9">
<label><a class="label {if !$cat || $cat.child}label-success{else}label-default{/if}" href="{Router::search_url($params, 'catid', NULL)}">不限</a></label>
<!--调用栏目分类，这种用法只能用于模块列表与搜索页面-->
{loop $related $t}
<label><a class="label {if $t.id==$cat.id}label-success{else}label-default{/if}" href="{Router::search_url($params, 'catid', $t.id)}">{$t.name}</a></label>
{/loop}
</div>
</div>
<!--category_search_field是调用当前栏目下的附加字段是否具有搜索字段功能，这种用法只能用于模块列表与搜索页面-->
{category_search_field module=MOD_DIR catid=$catid}
<div class="form-group row">
<label class="col-md-2 control-label">{$t.name}</label>
<div class="col-md-9">
<label><a class="label {if !$params[$t.field]}label-success{else}label-default{/if}" href="{Router::search_url($params, $t.field, NULL)}">不限</a></label>
{loop $t.data $v}
<label><a class="label {if $v.value==$params[$t.field]}label-success{else}label-default{/if}" href="{Router::search_url($params, $t.field, $v.value)}">{$v.name}</a></label>
{/loop}
</div>
</div>
{/category_search_field}
<!--按联动菜单搜索-->
<div class="form-group row">

<!--调用联动菜单address，pid为动态获取的地区id-->
{list action=linkage code=address pid=$params.csxz}
<label><a class="label {if $t.id==$params.csxz}label-success{else}label-default{/if}" href="{Router::search_url($params, 'csxz', $t.id)}">{$t.name}</a></label>
