小编kra*_*n2g的帖子

我已经LEFT JOIN从我的数据库中获取了2个表中的值.
查询是这样的:

SELECT *
FROM thread
  LEFT JOIN comments ON thread.id_thread = comments.id_thread
WHERE id_type = '1'
ORDER BY data DESC, hour DESC

然后我以这种方式输出值:

<?

while($row = mysqli_fetch_array($query))
{
echo '<div class="col-md-1"></div>';
echo '<div class="col-md-11">';
echo  $row['title'] ."<br><br>".$row['content']."<br><br>";
echo  $row['content_com'];
echo '<div class="col-md-2 pull-right">'. "date: ".$row['data']."<br>"."author: ".'<a href ="/user.php?id='.$row['username'].'">'.$row['username'].'</a>'.'</div>' ."<br><br>";
echo '<form role="form" action="commit.php" method="post"><div class="col-md-offset-1 col-md-9"><input class="form-control" type="text" name="comm"><input type="hidden" name="thread_id" value="'.$row['id_thread'].'"></div></form> <br><br><hr><br>';
echo '</div>';
}

mysqli_close($connect);
?>

然后在commit.php(表单操作)中:

<?php
session_start();

  if(isset($_SESSION['id']))
  {
    $servername = "mysql9.000webhost.com"; …
