我刚刚发现即使出现错误（reg_add_fail.php），我仍然会收到一封电子邮件。如果客户端被定向到 reg_add_fail.php，是否可以阻止脚本向我发送电子邮件？使困惑...

我简化了脚本以浓缩。

非常感谢。

放在exit()重定向之后

header("location: reg_add_fail.php");
exit();

仅仅因为您调用header()并不意味着脚本立即停止执行。呼唤exit()意志。

在您的代码中，PHP mail() 函数在 IF 语句之外被调用，因此您总是会收到电子邮件。

要仅在查询运行没有错误时发送电子邮件，请将 mail() 放在 if 语句中！

PHP

if ($result) { 
  mail($to, $subject, $msg, $headers);  
  $reg =          $_REQUEST['reg'] ; 
  $first_name =   $_REQUEST['first_name']; 
  header("location: reg_add_success.php?reg=" . urlencode($reg) . "&first_name=" . urlencode($first_name)); 
} 
else { 
  header("location: reg_add_fail.php"); 
  exit(); // as sugested by John Conde
}

编辑显示整个代码：

<?php

// Email Recipient
$to = 'newreg@41q.org';

// Email Subject
$subject = 'New Homeless Connection';


// Email Message
$msg = '
<html>
  <head>
    <title>New Homeless Connection</title>
  </head>
  <body>
    <table cellspacing="0" cellpadding="10" border="1" align="left">
      <tr>
        <td align="left" width="150px">Registery No.:</td>
        <td align="left">'.$reg.'</td>
      </tr>
      <tr>
        <td align="left">First Name:</td>
        <td align="left">'.$first_name.'</td>
      </tr>
      <tr>
        <td align="left">Connection Date:</td>
        <td align="left">'.$connect_date.'</td>
      </tr>
      <tr>
        <td align="left" colspan="2"><a href="http://www.41q.org/admin/" title="">http://www.41q.org/admin/</a></td>
      </tr>
    </table>
    <br>
    <br>
  </body>
</html>';

// Email Headers
$headers  = 'MIME-Version: 1.0' . "\r\n";
$headers .= 'Content-type: text/html; charset=iso-8859-1' . "\r\n";
$headers .= 'From: Homeless' . "\r\n";


date_default_timezone_set('America/Los_Angeles');
$submit_date = date("m/d/y g:i A") ; 

// Prepare Database Query
$order = "
  INSERT INTO reg_add (
    submit_date,
    connect_date,
    reg,
    first_name
  )
  VALUES (
    '".$submit_date."',
    '".$_POST['connect_date']."', 
    '".$_POST['reg']."nv', 
    '".$_POST['first_name']."'
  )";

// Query Database
$result = mysql_query($order);


// Check If the result is valid
if ($result) { 

  // send email
  mail($to, $subject, $msg, $headers);  

  // prepare and direct the user to the reg_add_success Page
  $reg =          $_REQUEST['reg'] ; 
  $first_name =   $_REQUEST['first_name']; 
  header("location: reg_add_success.php?reg=" . urlencode($reg) . "&first_name=" . urlencode($first_name)); 

} 
else {

  // send the user to the reg_add_fail Page
  header("location: reg_add_fail.php"); 

  // exit from the script
  exit();

}

?>
