php - 无法从组 id 2 中的表单插入数据库，但它插入到组 id 1 中

Question

                 <form method="post" action="" class="form-horizontal no-margin well">
                <div class="control-group">
                    <input type="text" name="post" id="post"  style="
width: 98%;
height: 50px;"/>                    </div>
                <div style="padding-left:95%!important" class="form-actions no-margin">
                  <button onClick="window.location.reload(true);" style="height:30px" name="submit" type="submit" class="btn btn-info">
                  <p>Post</p></button>
                </div>
              </form>
<?php
$link=mysql_connect("localhost","root","")or die("Can't Connect...");
mysql_select_db("project") or die("Can't Connect to Database...");
$q="SELECT * FROM post p , member m , groupp g WHERE p.group_id='".$dbgroupid."' and p.m_id=m.m_id ORDER BY p_id DESC";
  $queryRessource = mysql_query($q,$link) or die(mysql_error());
  $numrows=mysql_num_rows($queryRessource);

       }
       echo "</table>";
       }
        if(isset($_POST['submit'.$row['p_id']]))
  {
      if(empty($_POST['comment'.$row['p_id']])) 
      {
            echo '<script language="javascript">';
            echo 'alert("You Cant Add Empty Comment")';
            echo '</script>';
      }
      else {
          $p_id=$row['p_id'];
    $dbmemberid=$_SESSION['Member_ID'];
    $comment=$_POST['comment'.$row['p_id']];
    $link=mysql_connect("localhost","root","")or die("Can't Connect...");
    mysql_select_db("project") or die("Can't Connect to Database...");
    $Query="INSERT INTO `comment`(`comment_id`,`comment`,`p_id`,`group_id`,`m_id`) VALUES ('','$comment','$p_id','$dbgroupid','$dbmemberid')";
    mysql_query($Query,$link)or die (mysql_error());
     echo "<meta http-equiv='refresh' content='0'>";

    }}

            }

  if(isset($_POST['submit']))
  {
      if(empty($_POST['post'])) 
      {
            echo '<script language="javascript">';
            echo 'alert("You Cant Add Empty Post")';
            echo '</script>';
      }
      else {
    $post=$_POST['post'];
    $link=mysql_connect("localhost","root","")or die("Can't Connect...");
    mysql_select_db("project") or die("Can't Connect to Database...");
    $query="INSERT INTO `post` VALUES ('','$post','$dbmemberid','$dbgroupid')";
    mysql_query($query,$link)or die (mysql_error());
     echo "<meta http-equiv='refresh' content='0'>";

    }}
   ?>

我的问题是，我通过使用 $_get 获得了组 session ID，但是当我尝试插入组 2 (group_id=2) 时，它没有插入到数据库中，而是在组 id 1 (group_id=1) 中时插入到数据库中)

我的 session 设置为

if(isset($_SESSION['UserName']) && isset($_SESSION['Member_ID']))
{
     $dbusername=$_SESSION['UserName'];
     $dbmemberid=$_SESSION['Member_ID'];
     $dbgroupid=$_GET['group_id'];

    }

那么我需要做什么才能让我的表单发布在第二组中当我在群组 id=1 中插入帖子或评论时第 num 行回显每个帖子两次...

尝试为您的表单指定一个操作。即。

<?php $id = $_GET['id']; ?> 

<form method = "POST" action = "current_page.php?id=<?php echo $id; ?>">
