我想根据博客显示相关评论

Question

我正在使用codeignitor。我想根据博客显示相关评论。相关评论仅显示一个博客而非其他博客！ 这是我的代码：

<section>
  <div class="col-md-9 blog-contrainer">
    <?php if(!empty($blog_data) && isset($blog_data)){ foreach($blog_data as $blog_data) { ?>
    <div class="row blog">
      <div class="col-md-4">
        <img src="<?php echo base_url();?>assets/img/blog.png" class="img-thumbnail img-responsive">
      </div>

      <div class="col-md-8 blog-detail">
        <div class="row">
          <div class="blog-title">
            <h3> <?php echo $blog_data['blog_id']; ?> <?php echo $blog_data['blog_title']; ?></h3>
            <p>Written by
              <?php echo $blog_data[ 'firstname']; ?>
            </p>
          </div>
          <div class="social-follwers">
            <div class="following col-md-3">
              <a href="#"><i class="fa fa-thumbs-up" area-hidden="true"></i> Following<span class="badge">25</span></a>
            </div>
            <div class="Comments col-md-3">
              <a href="#"><i class="fa fa-comment" area-hidden="true"></i>Comments<span class="badge">25</span> </a>
            </div>
          </div>
          <div class="col-md-12">
            <p>
              <?php echo $blog_data[ 'blog_txt']; ?>
            </p>

          </div>


          <div class="col-md-12 comment-box">

            <?php //var_dump($query);die; if(isset($list) && !empty($list)) { foreach($list as $list) { if($list[ 'blog_id_frk']==$blog_data[ 'blog_id']){ ?>

                  <?php if(isset($list[ 'comment'])&& !empty($list[ 'comment'])){ echo $list[ 'comment']; } ?>
                </p>
              </div>
