Why does this php script work fine in firefox but

问题:

I have a script that mails me my form data for a classified ad. Yesterday when I left work it worked fine. Now it is only working in FireFox and I'm getting my "else" statement "We encountered an error sending your mail, please notify [e-mail]" in both Opera AND Safari which makes no sense to me.

What's causing this error, and why does it fail in some browsers but work in others?

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

<?php 
 $to = "[e-mail]" ; 
 $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{"Words"} = "Word Count";

 $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 [e-mail]"; } 
 }
}

回答1:

It'll work if you send it from your own email address with a PHP_EOL.

mail("[e-mail]", "subject", "body", "From: Me" . PHP_EOL); // 'From' can be anything

See PHP: mail - Manual.

Try the suggestions in the comments first, then try using this JavaScript code:

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

I've wrapped the submit code in an anonymous function rather than a string, which is encouraged here: Efficient JavaScript - Dev.Opera.

Also, using <script language= is deprecated, you should use type instead (text/javascript). See script - MDN.
