Question

我的网站在我的localhost上工作正常。但是，当我将最新的东西上传到服务器时，我收到以下错误：

[13-Sep-2010 20:40:22] PHP Notice:  Undefined variable: query in /home/mysite/public_html/zendamf_remote/MyScoreData.php on line 143

以下代码：

以下是我放在服务器上的内容。它抛出上述错误。它不是太漂亮，但它在本地工作。 localhost版本和服务器版本之间的唯一区别是第一次需要的路径。我有正确的路径，因为它对我所有的其他php类都是一样的。

为什么它不在服务器上工作，但在本地工作的任何想法？我该怎么办？

Answer 1

如果您包含或要求文件或查询变量来自另一个文件，请确保您在服务器上的所有文件和库路径都正确，它们可能与本地开发环境中的路径不同。

您能否发布代码？

Answer 2

最有可能的是，您在if()语句中检查的选项中没有任何选项匹配，因此永远不会定义$query，并且当代码到达{{1}时它试图运行一个NULL查询，基本上是mysql_query()

我怀疑如果您将实际的查询调用行更改为：

$result = mysql_query('');

您会看到脚本在此时中止并显示“null query”错误消息。就目前而言，函数调用最有可能返回$result = mysql_query($query) or die("MySQL error: " . mysql_error());以指示发生错误，然后您尝试在FALSE中使用FALSE值，从而生成{{1}错误。

要修复，请在所有mysql_fetch_assoc()语句之前放置一个默认查询，这样如果所有选项都不匹配，您仍然会有某种有效查询。或者，如果您不想在此时运行查询，则可以在if：

中包围查询/获取块。

... not a valid MySQL result resource

Answer 3

好的，我明白了。我在发布版本中使用了一个Alert来跟踪设置$ schoolPollSelections的Flex变量。它显示我的radioButton和list控件没有设置变量。此变量是MyScoreData使用的参数数组。因此，MyScoreData无法获取数据。

奇怪的是，当我在localhost上跟踪变量时，变量显示为具有所有参数。但是，当它在远程服务器上时，它没有设置。我不知道为什么。无论如何，我在两台主机上都正确设置了变量并且它可以工作。

感谢Stoosh，Marc B和Andrew Heath的帮助。
