爲什麼這個PHP腳本在firefox中工作正常，但不是Safari或Opera？

Question

我有一個腳本可以將我的表單數據發送給分類廣告。昨天當我離開工作時，它工作得很好。現在它只在FireFox中工作，我在Opera和Safari瀏覽器中收到了我的「else」聲明「我們遇到了發送郵件的錯誤，請通知XXXX@XX.COM」，這對我來說毫無意義。

什麼原因導致這個錯誤，爲什麼它在某些瀏覽器中失敗，但在其他瀏覽器中工作？

<script language="javascript"> 
function submitt() 
{ 
setTimeout('document.paypal.submit()',1000); 
} 
</script> 

<?php 
$to = "XXX@XXX.com" ; 
$from = $_REQUEST['email'] ; 
$name = $_REQUEST['Name'] ; 
$headers = "From: $from"; 
$subject = "Classified Tests"; 

$fields = array(); 
$fields{"Name"} = "Name"; 
$fields{"email"} = "Email"; 
$fields{"Phone"} = "Phone"; 
$fields{"Address"} = "Street Address"; 
$fields{"City"} = "City"; 
$fields{"State"} = "State"; 
$fields{"Zip"} = "Zip Code"; 
$fields{"Classification"} = "Classification"; 
$fields{"Ad-Headline"} = "Headline"; 
$fields{"Ad-Content"} = "Ad Content"; 
$fields{"Words"} = "Word Count"; 
$fields{"Weeks"} = "Weeks to Run"; 
$fields{"WordCount"} = "Total Words"; 
$fields{"Rate"} = "Word Rate"; 
$fields{"GrossAmountDue"} = "Gross Amount"; 
$fields{"NonProfit"} = "Non Profit Ad?"; 

$item_name = $_POST['item_name']; 
$amount = $_POST['amount'] ; 
$currency_code = $_POST['currency_code']; 
$no_shipping = $_POST['item_number']; 
$shipping = $_POST['item_number']; 
$cmd = $_POST['cmd']; 
$bn = $_POST['bn']; 
$no_note = $_POST['item_number']; 
$lc = $_POST['lc']; 
$business = $_POST['business']; 

$body = "This Ad has been submitted:\n\n"; foreach($fields as $a => $b){ $body .= sprintf("%20s: %s\n",$b,$_REQUEST[$a]); } 

if($from == '') {print "You have not entered an email, please go back and try again";} 
else { 
if($name == '') {print "You have not entered a name, please go back and try again";} 
else { 
$send = mail($to, $subject, $body, $headers); 
if($send) 
{print "Your Ad has been submitted, redirecting to paypal."; echo "<SCRIPT LANGUAGE='javascript'>submitt();</SCRIPT>";} 
else 
{print "We encountered an error sending your mail, please notify XXX@XXX.com"; } 
} 
} 


?>

是什麼造成這個錯誤，爲什麼它在某些瀏覽器，但其他人的工作失敗？

Answer 1

它會工作，如果你從你自己的電子郵件地址發送PHP_EOL。

mail("XXX@XXX.com", "subject", "body", "From: Me" . PHP_EOL); // 'From' can be anything 

請參閱PHP: mail - Manual。

Answer 2

嘗試建議的意見，然後再嘗試使用此JavaScript代碼：

<script type="text/javascript"> 
function submit() 
{ 
setTimeout(function(){document.paypal.submit();},1000); 
} 
</script> 

我包裹在一個匿名函數的代碼提交，而不是一個字符串，在這裏鼓勵：Efficient JavaScript - Dev.Opera。

此外，使用<script language=是棄用，你應該使用type代替（text/javascript）。見script - MDN。
