## 在首页模板中获取所有的产品分类 View: 在网站经常要用到调用所有的栏目,包含下级分类的方法,这个是框架没有的,需要自己写方法实现 > \themes\hx\portal\index.html <div class="gzcx_k_nr clearfix"> <div class="gzcx_k_nr_l"> <h4>产品中心</h4> <div class="panel-group wrap" id="accordion" role="tablist" aria-multiselectable="true"> <php>getCategoryAll(26);</php> </div> <div class="gzcx_k_nr_l_dh"> 24小时服务热线 <span>{$theme_vars.last_kfrx|default=''}</span> </div> </div> <div class="gzcx_k_nr_r"> <ul class="clearfix"> <php> $cid=""; $arr = json_decode(\app\portal\service\ApiService::allSubCategoriesCid(26),true); foreach ( $arr as $key => $val) { if( is_array($val) ) foreach( $val as $value) $cid.= $value.','; } if(!$cid){ $cid=26; } </php> <portal:articles limit="6" order="post.published_time DESC" categoryIds="$cid"> <li><a href="{:url('portal/Article/index',array('id'=>$vo.id,'cid'=>$vo.category_id))}"> <span class="gzcx_k_nr_r_img"><img src="{:cmf_get_image_url($vo.more.thumbnail)}"></span> <small>{$vo.post_title}</small></a></li> </portal:articles> </ul> </div> </div> 创建公共方法便于内页调用 getCategoryAll() > \app\common.php /* 获取所有的下级分类 */ function getCategoryAll($cid){ $arr = json_decode(\app\portal\service\ApiService::subCategories($cid,'id,name'),true); foreach ( $arr as $key => $val) { $nr=""; $nr.="<div class=\"panel\"><div class=\"panel-heading\" role=\"tab\" id='a$key'>"; $nr.="<h4 class=\"panel-title\">"; $nr.="<a role=\"button\" data-toggle=\"collapse\" data-parent=\"#accordion\" href='#a1$key'>".$val['name'] ; $nr.=" &nbsp; <i class=\"fa fa-angle-down\"></i> </a></h4></div>"; $bs = ($key==0) ?"in" :""; $nr.= "<div id='a1$key' class=\"panel-collapse collapse $bs \" role=\"tabpanel\" aria-labelledby='a$key'> <div class=\"panel-body\"><ul class=\"clearfix\">" ; //遍历所有的子分类,获取下级 $arr2 = json_decode(\app\portal\service\ApiService::subCategories($val['id'],'id,name'),true); foreach ( $arr2 as $key => $val2) { $url = url('portal/List/index',['id'=>$val2['id']]); $nr.= "<li><a href=\"$url\"><i class=\"fa fa-angle-double-right\"></i> &nbsp; $val2[name]</a></li>"; } $nr .= "</ul></div></div>" ; $nr .= "</div>" ; echo $nr; } } ### 方法说明: #### 这里的 subCategories() 是调用框架写好的方法 返回指定分类下的子分类;在页面转成数组后,遍历得出二级的分类,结合页面样式实现的功能。另类解决方案,个人建议用AJAX实现类似方法
