Php 引导面板未扩展

我正在使用bootstrap 3，我正在制作一个社交网站，这里的代码是显示帖子的面板的一部分。问题是它在切换上显示评论，但评论没有出现在页脚中，它正在穿过它…那么我的页面有什么问题，或者我如何扩展面板页脚

代码如下：

<div class="panel-footer"> 
Like <span class="glyphicon glyphicon-thumbs-up"></span>&nbsp;&nbsp;
        <a href='javascript:void(0)' onClick="javascript:toggle<?php echo $idp?>()" style="color:black">Comments</a>
    <div id='toggleComment<?php echo $idp;?>' style="display:none;">
    <form action="" method="POST"><!--FORM COMMENT-->
    <div class="form-group">                        
        <div class="rows" >
        <div class="col-sm-1" style="padding-right:2px;">
        <div class="compic">
                <img src="<?php echo $profilepic; ?>" style="width:100%;height:100%;" />
            </div>
        </div>
        <div class="col-sm-11" style="padding-left:3px; padding-bottom:7px">
              <textarea class="form-control expandable pull-left" name="comment<?php echo $idp;?>" id="comment" placeholder="Write a comment..." required>
                    </textarea>
        </div>
    </div>
    <hr>
    <button type="submit" class="btn btn-primary pull-right" name="subcom<?php echo $idp;?>"><b>Comment</b></button>
    <div class="clearfix"></div>
    </div></form>
    <div class="rows" >
    <?php
    $postid=$idp;
    $postby=$id;
    $postto=$uid;
    if(isset($_POST['subcom'.$postid]))
    {   $postbody=$_POST['comment'.$postid];
        if($postbody!="")
        {$res=mysqli_query($con,"INSERT INTO comment VALUES('','$postby','$postto','$postbody','$postid')");}           
    }
    $show=mysqli_query($con,"SELECT * FROM comment WHERE postid='$idp' ORDER by id");
    while($show_row=mysqli_fetch_array($show))
    {
        $commentbyid=$show_row['cby'];
        $combody=$show_row['cbody'];
                $cbyquery=mysqli_query($con,"SELECT * FROM user WHERE id='$commentbyid'") or die(mysqli_error($con));
                $cby=mysqli_fetch_array($cbyquery);
                $cpic=$cby['profpic'];
                if ($cpic== "" || !file_exists("userdata/profile_pics/$cpic"))
                {
                    $cpic = "images/default_pic.jpg";
                }
                else
                {
                    $cpic = "userdata/profile_pics/".$cpic;
                }
                $cname=ucfirst(strtolower($cby[1]));
                $csname=ucfirst(strtolower($cby[2]));
            ?>
                <div class="col-sm-1" style="padding-right:2px;">
                    <div class="compic">
                        <img src="<?php echo $cpic; ?>" style="width:100%;height:100%;" />
                    </div>
                </div>
                <div class="col-sm-11" style="padding-left:3px;">
                <?php echo $cname." ".$csname;?><br>
                <?php echo $combody;?>
                </div>
            <?php
    }
    ?></div>
    </div><!--Toggle Ends here-->               
</div>

“id=”comment“placeholder=”写入注释…”必填项>

最后得到它是因为
，当我在
之后使用它时，它得到了解决。不，它仍然是一样的
