在本地主機上工作，但在部署到服務器時出現錯誤

Question

我的網站在我的本地主機上正常工作。但是，當我上傳了最新的東西到服務器，我收到以下錯誤：

[13-Sep-2010 20:40:22] PHP Notice: Undefined variable: query in /home/mysite/public_html/zendamf_remote/MyScoreData.php on line 143 
[13-Sep-2010 20:40:22] PHP Warning: mysql_fetch_object(): supplied argument is not a valid MySQL result resource in /home/mysite/public_html/zendamf_remote/MyScoreData.php on line 146

下面的代碼：

下面是我把服務器上。它會拋出上述錯誤。這不太漂亮，但它在本地工作。本地主機版本和服務器版本之間的唯一區別是第一次需求的路徑。我有正確的道路，因爲它對我所有其他的PHP類都是一樣的。

任何想法，爲什麼它不在服務器上工作，但在本地工作？我該怎麼辦？

謝謝。

Answer 1

好吧，我想通了。我在發佈版本中使用了一個Alert來跟蹤一個設置$ schoolPollSelections的Flex變量。它顯示變量沒有被我的radioButton和列表控件設置。該變量是MyScoreData使用的一組參數。因此，MyScoreData無法獲取數據。

奇怪的是，當我在本地主機上跟蹤它時，變量顯示爲具有所有參數。但是，它在遠程服務器上時沒有設置。我不知道爲什麼。無論如何，我已經在兩臺主機上正確設置了變量，並且它可以正常工作。

謝謝Stoosh，Marc B和Andrew Heath的熱心幫助。

Answer 2

如果要包括或需要的文件或查詢變量來自另一個文件，確保文件和庫所有的路徑是在服務器上是正確的，他們可能是對的路徑不同的當地發展環境。

你能不能也請發佈代碼？

Answer 3

最有可能的是怎麼發生的是，你檢查在if()聲明匹配那個球的選項NONE，所以$query從未定義，當代碼到達mysql_query()線，它試圖運行一個NULL查詢，基本上$result = mysql_query('');

我懷疑如果你改變實際的查詢電話線，以這樣的：

$result = mysql_query($query) or die("MySQL error: " . mysql_error()); 

你會看到腳本中止在與「空查詢」錯誤信息點。現在，函數調用很可能返回FALSE以指示發生錯誤，然後嘗試在mysql_fetch_assoc()中使用FALSE值，該值產生... not a valid MySQL result resource錯誤。

要解決此問題，請在所有if()語句之前放置默認查詢，以便如果沒有任何選項匹配，您仍然有某種有效查詢。或者，如果你不想運行在這一點上查詢，你可以環繞查詢/在if獲取模塊：

if (!empty($query)) { 
     $result = mysql_query(...) 
     // etc... 
     return($ret); 
} else { 
     return($some_default_value_to_signify_nothing_was_done); 
}
