                ## 在首頁模板中獲取指定分類下(含子欄目)的所有文章 View: 在網站經常要用到調用欄目下(含子欄目)的所有的文章,自己寫的方法,寫得不好勿怪 > \themes\hx\portal\index.html <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> 調用自定義API數據源獲取數據 allSubCategoriesCid(26) > \app\portal\service\ApiService.php /** * [allSubCategoriesCid]根據path查詢,得到所有分類 * @param [string] $categoryId * @return [子分類ID] */ public static function allSubCategoriesCid($categoryId) { $portalCategoryModel = new PortalCategoryModel(); $categoryId = intval($categoryId); if ($categoryId !== 0) { $category = $portalCategoryModel->field('path')->where('id', $categoryId)->find(); if (empty($category)) { return []; } $categoryPath = $category['path']; } else { $categoryPath = 0; } $where = " status='1' AND delete_time='0' AND path like '$categoryPath-%'"; return $portalCategoryModel->where($where)->field('id')->select(); } ### 方法說明: #### 根據指定的總分類id來查詢數據,方法里面是根據 path 的字段來查詢獲取子分類ID ,在頁面是通過json_decode將對象轉成數組,然后給標簽調用 categoryIds="$cid" ,方法寫得不太好,僅作參考(個人推薦使用AJAX實現相關的功能)
