显示3个表格中的数据

Question

我有3个表，第一个是表名 Post ，第二个是 comment ，第三个是 { {1}} 即可。我想显示所有3个表，但我的代码太长了。你能建议我吗？

defineComment

我也尝试下面的代码，但它不起作用。

$r = $this->w->listwall();
    if($r)
    {
        foreach($r as $key)
        {
            // load comment to view data
            $pc['pc_comment'] = $this->w->get_comments($key['p_id']);
            $data['wall'][] = [
                'u_id'=>$key['u_id'],
                'p_id'=>$key['p_id'],
                'u_fname'=>$key['u_fname'],
                'u_lname'=>$key['u_lname'],
                'p_text'=>$key['p_text'],
                'p_date'=>$key['p_date'],
                'u_pf' =>$this->pf->getprofile($key['u_id']),
                'p_img'=>$this->w->getimg($key['p_id']),
                'cover'=>$this->w->getcoverimg($key['p_id']),
                'bgpf' =>$this->w->getbgimg($key['p_id']),
                'p_link'=>$key['p_link'],
                'pc_comment'=>$this->w->get_comments($key['p_id']),
                'pc_count'=>$this->w->get_count_comment($key['p_id']),
                'pc'=>$this->load->view('wall/v_comment_wall', $pc, TRUE),
                'p_like'=>$this->w->get_list_like($key['p_id']),
                'count_like'=>$this->w->count_like_post($key['p_id'])
            ];
        }
        $data['pf'] = $this->pf->getprofile(uid());
        //$data['edittext'] =
        //if(count($data) >= 1){
        $this->load->view('wall/v_wall',$data);
