我希望使用codeigniter为每个帖子发表所有评论

Question

图像显示了我想要显示每个帖子的所有评论的所有帖子.i用红色标记了评论部分

public function forum(){
    $config['base_url'] = site_url('tourism_con/forum');  
    $config['total_rows'] = $this->db->get('forum_posts')->num_rows();
    $config['uri_segment'] = 3;
    $config['per_page'] = 5; 
    $config['full_tag_open'] = "<ul class='pagination pagination-lg'>";
    $config['full_tag_close'] ="</ul>";
    $config['num_tag_open'] = "<li>";
    $config['num_tag_close'] = '</li>';
    $config['cur_tag_open'] = "<li class='disabled'><li class='active'><a href='#'>";
    $config['cur_tag_close'] = "<span class='sr-only'></span></a></li>";
    $config['next_tag_open'] = "<li>";
    $config['next_tagl_close'] = "</li>";
    $config['prev_tag_open'] = "<li>";
    $config['prev_tagl_close'] = "</li>";
    $config['first_tag_open'] = "<li>";
    $config['first_tagl_close'] = "</li>";
    $config['last_tag_open'] = "<li>";
    $config['last_tagl_close'] = "</li>";
    $data['forum_title']='Forum :: Home Page';
    $data['forumPosts']='forumPosts';
    $data['forum_details']=  $this->tourism_model->get_forum_post($config);
    $data['comment_count']=$this->tourism_model->get_comments_by_post();
    $this->load->view('Forum/forum_home',$data);
}

以上代码是控制器部分。和以下代码模型从数据库中检索所有帖子。

public function get_forum_post($config){
    $this->pagination->initialize($config);
    $this->db->order_by("post_id", "desc");
    $query =   $this->db->get('forum_posts',$config['per_page'],$this->uri->segment(3));  
    return $query->result();
}

以下代码用于模型中的注释以从数据库中检索注释

public function get_comments_by_post(){
   $this->db->select('comment_id');
   $this->db->distinct();
   $this->db->from('comment');
   $query = $this->db->get();
   return $query->num_rows();
}

视图代码部分

<div class='container forumBG'>
   <?php 
     foreach ($forum_details as $forum_post_details) {
    ?>
    <div class="row">
 	 <div class="forumPosts col-xs-10 col-xs-offset-1 col-sm-8 col-sm-offset-1 ">
 	   <h3 autofocus='autofocus'><strong > <a href="<?php echo site_url()?>tourism_con/full_post_details/?post_id=<?php echo $forum_post_details->post_id?>"> <?php echo $forum_post_details->topic_title?></a></strong></h3>
        Written By:<strong><?php echo $forum_post_details->user_name?></strong><br/>
 	    Posted on <strong><?php echo $forum_post_details->written_time?></strong>
 	    <p><?php echo substr($forum_post_details->description,0,105) ;?> ...</p>
 	 </div>
 	   <div class="col-xs-10 col-xs-offset-1 col-sm-2 col-sm-offset-0 forumComment">
 		 <div class="row">
 		  <div class="col-sm-12 forumCommentSub">
 			<i class="fa fa-comments fa-1x"> <?php echo $comment_count;?></i>
 		  </div>
 		  <div class="col-sm-12 forumCommentSub">
 		  	<i class="fa fa-eye fa-1x"> <?php echo $forum_post_details->post_views?></i>
 		  </div>
 		 </div>
 	  </div>
 	</div>
 
 <?php }?>

上面的代码问题是它检索来自database.i不想要它的所有注释。我希望每个post.how的所有注释写入查询以检索每个帖子的数据。

这样做：在post_id函数中过去get_comments_by_post

public function get_comments_by_post($postid){
    $q = $this->db->query("SELECT * FROM comments WHERE post_id = $postid");
    if($q->num_rows() > 0) {
        return $q->result_array();
    } else {
        return '';
    }
}
