Question

我在php中得到了这个错误。我不明白为什么......

以下是我的连接建立方式：

<?php

$hostname_QASite = "localhost";
$database_QASite = "qasite";
$username_QASite = "root";
$password_QASite = "";
$QASite = mysql_pconnect($hostname_QASite, $username_QASite, $password_QASite) or trigger_error(mysql_error(),E_USER_ERROR); 
?>

我的查询如下：

   mysql_select_db($database_QASite, $QASite) or die(mysql_error());
$query_get_all_topics = "SELECT topic_id, title FROM topic";
$get_all_topics = mysql_query($query_get_all_topics, $QASite) or die(mysql_error());
$row_get_all_topics = mysql_fetch_assoc($get_all_topics);
$totalRows_get_all_topics = mysql_num_rows($get_all_topics);

然后我遍历row_get_all_topics ...

代码有什么问题？

编辑：

当我尝试在数据库中的不同结果上循环2次时，我得到了该错误。

更新：

                  <tr>
                    <td><a href="/QASite/Admin/create_subTopic.php?topic_id=<?php echo $row_get_all_topics['topic_id']; ?>"></a></td>
                    </tr>
                  </table>

                </td>
              </tr>
          </table>
     <?php 
         **}while($row=mysql_fetch_assoc($result));** 1 FIRST LOOP
      }//end suptopic search

      ?>
  <?php **} while ($row_get_all_topics = mysql_fetch_assoc($get_all_topics)); ?>** 2ND LOOP

一旦我添加这一行，在循环内查询数据库，页面就会显示错误..

$result=$mysql_query("SELECT title, sub_topic_id FROM sub_topic WHERE topic_id=".$row_get_all_topics['topic_id']) or die(mysql_error());
