我真的越来越沮丧。我正在将我的网站从 php 5.2 移动到 php 5.3。将信息从我的表单添加到 mysql 数据库时，会添加一条空记录，并且我收到此错误消息，它们是相互连接的。错误日志消息是：

[Tue Jul 16 12:37:08 2013] [warn] [client XX.XX.XXX.XXXX] mod_fcgid: stderr: PHP Notice:  Undefined variable: prijs in XXX/page.php on line 100, referer: XXX/page.php
[Tue Jul 16 12:37:08 2013] [warn] [client XX.XX.XXX.XXXX] mod_fcgid: stderr: PHP Notice:      Undefined index: type_contract in XXX/page.php on line 116, referer: XXX/page.php
[Tue Jul 16 12:37:08 2013] [warn] [client XX.XX.XXX.XXXX] mod_fcgid: stderr: PHP Notice:  Undefined index: klantnummer in XXX/page.php on line 117, referer: XXX/page.php
[Tue Jul 16 12:37:08 2013] [warn] [client XX.XX.XXX.XXXX] mod_fcgid: stderr: PHP Notice:  Undefined index: datum in XXX/page.php on line 118, referer: XXX/page.php
[Tue Jul 16 12:37:08 2013] [warn] [client XX.XX.XXX.XXXX] mod_fcgid: stderr: PHP Notice:  Undefined index: omschrijving in XXX/page.php on line 119, referer: XXX/page.php

我已经尝试了一切，比如添加

if (isset($_POST['prijs'])) { $prijs = $_POST['prijs']; }

它所指的代码是：

<?php if (isset($_GET['action']) && ($_GET['action'] == "abonnement_toevoegen")) {

$prijs = $_POST['prijs'];  <=== this is the code is referring to!!!

$prijs_comma = str_ireplace(",", ".", "$prijs");

$prijs = $prijs_comma;
$btw = $prijs * 0.21;
$totaal = $prijs + $btw;

$prijs = round($prijs, 2);
$btw = round($btw, 2);
$totaal = round($totaal, 2);

$prijs_weergave = str_ireplace(".", ",", "$prijs");
$btw_weergave = str_ireplace(".", ",", "$btw");
$totaal_weergave = str_ireplace(".", ",", "$totaal");

include("include_addslashes.php");

$type_contract = $_POST['type_contract']; <=== this is the code is referring to!!!
$klantnummer = $_POST['klantnummer']; <=== this is the code is referring to!!!
$datum = $_POST['datum']; <=== this is the code is referring to!!!
$omschrijving = $_POST['omschrijving']; <=== this is the code is referring to!!!

$sql = "INSERT INTO wi_abonnementen
(
type_contract,
klant_id,
factuurdatum,
omschrijving,
prijs,
btw,
totaal
 )
VALUES
(
'$type_contract',
'$klantnummer',
'$datum',
'$omschrijving',
'$prijs_weergave',
'$btw_weergave',
'$totaal_weergave'
)";

if (!mysql_query($sql, $con)) {
    die('Error: ' . mysql_error());
}

include("include_stripslashes.php");
var_dump($_POST);
?>

请帮忙，我在不同的网站上一遍又一遍地收到此错误消息。

表单的 HTML 代码为：

<form action="finance.php?action=abonnement_toevoegen" method="post"  name="abonnement_toevoegen">
<table>
<tr>
    <td>Type</td>
    <td><select name="type_contract" size="1">

                        </select>       
    </td>
</tr>

    <td>&#8364; <input class="form" type="Text" name="prijs" value="" size="10">    </td>

    <td>&nbsp;</td>
    <td>&nbsp;</td>

<tr>
    <td></td>
    <td><input type="submit" class="form" value="Voeg toe"></td>
</tr>
</table>
<div id='abonnement_toevoegen_errorloc' class='error_strings'></div>
</form>

谢谢！

我不确定为什么它可以在以前版本的 PHP 中工作，但不能在新版本中工作。

但是，我确定问题是整个事情在第一次运行时运行良好，然后重定向回同一页面，其中没有POST设置任何变量，因为它不是来自表单。

尝试摆脱任何重定向，这应该可以解决它。然后根据需要对重定向进行排序（尽管在提交表单后您不需要再次重定向）。

如果您想让我看看还有什么其他情况，请随时发布您的其余代码。
