当我提交表格时.. 表单显示'错误'消息，表示查询无法正常工作.. 我将代码与其他代码进行比较，看起来很相似...... 我不知道该怎么做 拜托...... 帮助我...
（这是表格代码）
<?php
if(isset($_GET['bookno']))
$bookingno = $_GET['bookno'];
elseif(isset($_POST['bookno']))
$bookingno = $_POST['bookno'];
else
$bookingno = "";
$db = mysql_connect('localhost','root')
or die ("unable to connect");
mysql_select_db('fyp',$db) or die ("able to select");
$sql_select = "SELECT * FROM `booking` "
. " WHERE `bookingno`='".trim($bookingno)."'";
$result = mysql_query($sql_select) or die ("Query failed!");
$row = mysql_fetch_array($result);
extract($row);

答案 0 :(得分：3)
$bookingno=mysql_real_escape_string($_POST['bookingno']);
等等
请注意
$result = mysql_query($sql) or trigger_error (mysql_error().' in '.$sql);
呼叫将提供更多信息

请改为尝试：
$result = mysql_query($sql) or die('Invalid query: ' . mysql_error());
它应该会给你一个更好的错误信息。

您没有指定列名列表。您是否为表中的每一列提供了值？
