PHPMailer的投擲MySQL錯誤

Question

我想使用的PHPMailer發出簡訊，但每次我試圖觸發它的時候我不斷收到以下錯誤。我不確定我的sql語法是否正確？

Warning: mysql_fetch_array() : supplied argument is not a valid MySQL result resource in view.html.php(38):eval()'d code on line 32

<?php 
$formid = $_GET[token]; 
$templatequery = mysql_query(" 
    SELECT * 
    FROM hqfjt_chronoforms_data_addmailinglistmessage 
    WHERE cf_id = '$formid'" 
) or die(mysql_error()); 

$templateData = mysql_fetch_object($templatequery); 

$gasoiluserTemplate = $templateData->gasoilusers; 
$dervuserTemplate = $templateData->dervusers; 
$kerouserTemplate = $templateData->kerousers; 
$templateMessage = $templateData->mailinglistgroupmessage; 
?> 

<?php

// $body = file_get_contents('contents.html'); 
$body = 'Dear Test this is a test.'; 
// $body = preg_replace('/\\\\/i', $body); 

$mail->SetFrom('crea@cruiseit.co.uk', 'List manager'); 
$mail->AddReplyTo('crea@cruiseit.co.uk', 'List manager'); 

$mail->Subject = "Mailing List Test"; 

$query = " 
    SELECT leadname,businessname,email

WHERE keromailinglist='$kerolist' 
    AND dervmailinglist='$dervlist' 
    AND gasoilmailinglist='$gasoillist'"; 
$result = @MYSQL_QUERY($query); 

while ($row = mysql_fetch_array ($result)) { 
    $mail->AltBody = "To view the message, please use an HTML compatible email viewer!"; // optional, comment out and test 
    $mail->MsgHTML($body); 
    $mail->AddAddress($row["email"], $row["full_name"]); 
    $mail->AddStringAttachment($row["photo"], "YourPhoto.jpg"); 

    if(!$mail->Send()) {

    // Clear all addresses and attachments for next loop 
    $mail->ClearAddresses(); 
    $mail->ClearAttachments(); 
} 
?>

我現在已經添加了錯誤檢查，但現在只是得到了一個空白頁，沒有錯誤，也沒有郵件？

你的代碼，它沒有做任何錯誤檢查，所以這是毫不奇怪的查詢打破靜默，當它失敗。檢查錯誤，它會告訴你什麼是錯誤的 - 如何做到這一點在manual on mysql_query()或這reference question.概述。並刪除mysql_query()前面的@！例如：

$result = mysql_query($query); 

// Bail out on error 
if (!$result) 
    { 
    trigger_error("Database error: ". 
        mysql_error(). 
        " Query used was: ". 
        htmlentities($query), E_USER_ERROR); 
    die(); 
    } 

這將告訴你什麼不順心準確，並且正在使用什麼最終的查詢看起來像這樣。

作爲一個側面說明（和可能，也解決你的根本原因）你看代碼很容易受到SQL injection。這可能是什麼打破了你的查詢。

你需要做的mysql_real_escape_string()對所有傳入值，像這樣：

$formid = mysql_real_escape_string($_GET["token"]);

函數調用之前@被抑制應該告訴你發生了什麼錯誤。
