PHP中的函數無法識別

我有一些簡單的PHP腳本，我正在寫一個網站，我遇到了一個問題，我找不出原因。PHP中的函數無法識別

錯誤：

Notice: Undefined variable: votePosts in C:\wamp\www\fec\displaytable.php on line 23

我想象的是，這也發生的原因：

Warning: Invalid argument supplied for foreach() in C:\wamp\www\fec\displaytable.php on line 2

這是索引頁的代碼：

<html> 
<?php 
include ("includes.php"); 
include ("displaytable.php"); 
$votePosts = GetVotePosts(); 
?> 
</html>

這是GetVotePosts功能在包含文件中

function GetVotePosts($inId=null) 
{ 
if(isset($_POST['sort'])) 
{ 
    $sort = $_POST['sort']; 
} 
else 
{ 
    $sort = "district ASC"; 
} 
$query = mysql_query("SELECT reports.comm_name, reports.fec_id, reports.form_type, reports.file_id, reports.id, reports.line101, reports.line81, reports.line22, reports.line16, reports.line15, reports.line13a, reports.line11c, reports.line11aiii, campaigns.incumbency, campaigns.party, campaigns.candidate, campaigns.district FROM reports,campaigns WHERE reports.fec_id = campaigns.fecid ORDER BY " . $sort); 
$postArray = array(); 
while ($row = mysql_fetch_assoc($query)) 
{ 
    $myPost = new VotePost($row['comm_name'], $row['fec_id'], $row['form_type'], $row['file_id'], $row['id'], $row['line101'], $row['line81'], $row['line22'], $row['line16'], $row['line15'], $row['line13a'], $row['line11c'], $row['line11aiii'], $row['incumbency'], $row['party'], $row['candidate'], $row['district']); 
     array_push($postArray, $myPost); 
} 
return $postArray; 
}

這是line23那是錯誤的來源：

foreach ($votePosts as $post)

任何想法是什麼原因造成了這個問題。

'$ votePosts'定義在哪裏？你嘗試過var_dump（）嗎？ –

錯誤顯示在displaytables.php中，而不是您的includes.php。我的猜測是你需要重新排序你的語句爲'include（'includes.php'）; $ votePosts = GetVotePosts（）; include（'displaytable.php'）;' – jprofitt

$ votePosts在索引 – jimstandard

在包含聲明變量之前包含文件。請試試這個

<html> 
<?php 
include ("includes.php"); 
$votePosts = GetVotePosts(); 
include ("displaytable.php"); 
?> 
</html>

displaytable.php您將需要在全局空間中聲明$ votePosts： global $ votePosts; – Mike
