我正在尝试创建一个计费历史记录页面，用户可以在其中看到一个表格，其中包含表格格式的购买历史记录。我正在尝试为每一行添加一个链接，以便用户可以查看每个订单的完整发票详细信息。

当他们点击链接时（我在这个脚本之后包含了概述页面的脚本）这个脚本应该执行查询，但我只是得到一个空的消息查询。

任何人都可以发现错误吗？

谢谢！！

这是显示完整计费历史记录的脚本，其中包含与执行查询的脚本的链接（上图）。

<?php

include("mainfile.php");
include(XOOPS_ROOT_PATH."/header.php");


$host="localhost"; // Host name 
$username="username"; // Mysql username 
$password="password"; // Mysql password 
$db_name="db name"; // Database name 
$tbl_name="tbl name"; // Table name 

// Connect to server and select database.
mysql_connect("$host", "$username", "$password")or die("cannot connect"); 
mysql_select_db("$db_name")or die("cannot select DB");

$sql="SELECT * FROM $tbl_name  WHERE uid='";
$sql=$sql .  $xoopsUser->uid("s") . "'  AND Paid='Y'";


$result=mysql_query($sql);
?>

<table width="400" border="0" cellspacing="1" cellpadding="0">
<tr>
<td>
<table width="400" border="1" cellspacing="0" cellpadding="3">
<tr>
<td colspan="4"><strong>List data from mysql </strong> </td>
</tr>

<tr>
<td align="center"><strong>Billing Date</strong></td>
<td align="center"><strong>Invoice Number</strong></td>
<td align="center"><strong>Description</strong></td>
<td align="center"><strong>Total GBP</strong></td>
<td align="center"><strong>View</strong></td>
</tr>

<?php
while($rows=mysql_fetch_array($result)){
?>

<tr>
<td><? echo $rows['date']; ?></td>
<td><? echo $rows['TicketID']; ?></td>
<td><? echo $rows['project']; ?></td>
<td><? echo $rows['grandTotal']; ?></td>


<td align="center"><a href="http://website.co.uk/site/viewInvoice.php?TicketID=<? echo     $rows['TicketID']; ?>">View</a></td>

<?php
}
?>

</table>
</td>
</tr>
</table>

<?php
mysql_close();
include(XOOPS_ROOT_PATH."/footer.php");

改变这个：

// Get a specific result from the "example" table
$result = mysql_query($Sql) or die(mysql_error());

对此：

$result = mysql_query($sql) or die(mysql_error());

在 viewInvoice.php 中，还可以查看其他有关安全性等的评论。

改变这个

<a href="http://website.co.uk/site/viewInvoice.php?TicketID=<? echo $rows['TicketID']; ?>">View</a></td>

对此

<?php 
echo "href=http://website.co.uk/site/viewInvoice.php?TicketID=" . $rows['TicketID'] . ">View</a>";
?>

检查这些行：

// Retrieve data from database 
$sql="SELECT * FROM $tbl_name WHERE TicketID='$TicketID'";
$result=mysql_query($sql);
$rows=mysql_fetch_array($result);

// Get a specific result from the "example" table
$result = mysql_query($Sql) or die(mysql_error());

您正在$result使用返回值覆盖变量，mysql_query从中获取不存在的参数：$Sql

PHP 变量名区分大小写！

<?php

$host="localhost"; // Host name

$result  = mysql_query($sql);



echo "<table width='100' border='1' cellpadding='0' cellspacing='0' id='records'>";
print "<h3 align='center'><strong>Billing History</strong></h3><p>";
echo "<tr>

    echo $row['project'];
    echo "</td><td> "; 
    echo $row['grandTotal'];

echo "</table>";

第二个脚本：

<?php

include("mainfile.php");
include(XOOPS_ROOT_PATH."/header.php");


$host="localhost"; // Host name 
$username="username"; // Mysql username 
$password="password"; // Mysql password 
$db_name="db name"; // Database name 
$tbl_name="tbl name"; // Table name 

// Connect to server and select database.
mysql_connect($host, $username, $password)or die("cannot connect"); 
mysql_select_db($db_name)or die("cannot select DB");

$sql="SELECT * FROM `".$tbl_name."`  WHERE `uid`='".$xoopsUser->uid("s"). "'  AND `Paid`='Y'";
$result=mysql_query($sql);
?>

<table width="400" border="0" cellspacing="1" cellpadding="0">
<tr>
<td>
<table width="400" border="1" cellspacing="0" cellpadding="3">
<tr>
<td colspan="4"><strong>List data from mysql </strong> </td>
</tr>

<tr>
<td align="center"><strong>Billing Date</strong></td>
<td align="center"><strong>Invoice Number</strong></td>
<td align="center"><strong>Description</strong></td>
<td align="center"><strong>Total GBP</strong></td>
<td align="center"><strong>View</strong></td>
</tr>

<?php
while($rows=mysql_fetch_array($result)){
?>

<tr>
<td><? echo $rows['date']; ?></td>
<td><? echo $rows['TicketID']; ?></td>
<td><? echo $rows['project']; ?></td>
<td><? echo $rows['grandTotal']; ?></td>


<td align="center"><a href="http://website.co.uk/site/viewInvoice.php?TicketID=<? echo $rows['TicketID']; ?>">View</a></td>
</tr>

<?php
}
?>

</table>
</td>
</tr>
</table>

<?php
mysql_close();
include(XOOPS_ROOT_PATH."/footer.php");
?>

对不起。愚蠢的我。试试那个。。
