做项目的时候，在用ThinkCMF在首页调用指定的栏目文章，但是没有找到好的方法，就自己写了一个。

但是又不想写标签，就在公用方法里面实现了：找到common.php

操作数据库，要用到think的控制器和think的数据库类：

     field(array('id','parent_id'))->select();    $category_arr = array();    $cur_category_list = array();    array_push($cur_category_list,intval($id));    foreach($category_list as $v){        $arr = array();        $arr['id'] = $v['id'];        $arr['pid'] = $v['parent_id'];        array_push($category_arr,$arr);    }    //得到当前栏目所有的子栏目ids    $cur_category_ids = array_merge($cur_category_list,get_all_child($category_arr,$id));    //获取当前所有子栏目的所有文章ids    $all_post_ids_arr = array();    $all_post_ids = Db::name('portal_category_post')->where('category_id','in',$cur_category_ids)->field(array('post_id'))->select();    foreach($all_post_ids as $v){        array_push($all_post_ids_arr,$v['post_id']);    }            // 获取当前栏目及子栏目所有的文章列表    $where = array();    $where['id'] = array('in',$all_post_ids_arr);    $where['post_type'] = 1;    $where['post_status'] = 1;    $pagelist_arr = Db::name('portal_post')->where($where)->paginate($limit);    $page = $pagelist_arr->render();    // 处理跳转链接 和 栏目的图片    $pagelist = array();    foreach($pagelist_arr as $k => $v){        $v['thumb'] = '/upload/'.json_decode($v['more'],true)['thumbnail'];        $v['category_id'] = get_category_id($v['id']);        array_push($pagelist,$v);    }    return $pagelist;}function get_category_id($id){    $categoryinfo = Db::name('portal_category_post')->where('post_id','eq',$id)->field('category_id')->find();     return $categoryinfo['category_id'];}

怎么调用？

     
     
      
    
       
        
       
    
       
        
                                {
   $v['post_title']}            {
   $v['url']}                        
       
      
     

即可
