Question

到目前为止，以下用于联系表单的PHP代码运行良好，但我的错误日志文件突然说第21行有一条未定义的变量消息，有时在第27行。

<?php
$to = "name@email.com"; //This is the email address you want to send the email to
$subject_prefix = "Enquiry"; //Use this if you want to have a prefix before the subject

if(!isset($_GET['action']))
{
    die("You must not access this page directly!"); //Just to stop people from visiting get-in-touch.php normally
}

/* Now lets trim up the input before sending it */

$fname = trim($_GET['fname']); //The senders name
$lname = trim($_GET['lname']); //The senders lname
$email_id = trim($_GET['email_id']); //The senders email id
$pphone = trim($_GET['pphone']); //The senders phone
$cname = trim($_GET['cname']);  //The senders message
$subject = trim($_GET['subject']);  //The senders subject

$message = "".$message."\n Nmae: ".$fname."\n Address: ".$lname."\n Email: ".$email_id. "\n Phone: ".$pphone."\n Commient: ".$cname."\n subject: ".$subject;

$headers = "From: ".$email_id."";
//$headers .= 'Bcc: name@email.com' . "\r\n";
mail($to,$subject,$message,$headers); //a very simple send

echo 'Thank you '.$name.', your email has been sent.'; 
//now lets update the "contactarea" div on the contact.html page. The contactarea| tell's the javascript which div to update.
?>

您在定义之前使用$message。在$message = '';之前添加$message = ....(something);为什么在您的情况下，$message在邮件本身中连接了<?php $to = "name@email.com"; //This is the email address you want to send the email to $subject_prefix = "Enquiry"; //Use this if you want to have a prefix before the subject if(!isset($_GET['action'])) { die("You must not access this page directly!"); //Just to stop people from visiting get-in-touch.php normally } /* Now lets trim up the input before sending it */ $fname = trim($_GET['fname']); //The senders name $lname = trim($_GET['lname']); //The senders lname $email_id = trim($_GET['email_id']); //The senders email id $pphone = trim($_GET['pphone']); //The senders phone $cname = trim($_GET['cname']); //The senders message $subject = trim($_GET['subject']); //The senders subject $message = ''; $message = "".$message."\n Nmae: ".$fname."\n Address: ".$lname."\n Email: ".$email_id. "\n Phone: ".$pphone."\n Commient: ".$cname."\n subject: ".$subject; $headers = "From: ".$email_id.""; //$headers .= 'Bcc: name@email.com' . "\r\n"; mail($to,$subject,$message,$headers); //a very simple send echo 'Thank you '.$name.', your email has been sent.'; //now lets update the "contactarea" div on the contact.html page. The contactarea| tell's the javascript which div to update. ?>？

固定代码;

$subject_prefix

顺便说一下：perldoc perlop未使用。

您在错误的地方使用$message。

少数事情：

为什么在没有$_GET的情况下使用$_POST?。我建议你使用 $_POST因为您处理用户信息。$_GET可能会用于发送非敏感数据。

另外，我建议您关闭括号。因为使用括号确实有助于更轻松地跟踪块的开始和结束位置。

$to = "name@email.com"; //This is the email address you want to send the email to
$subject_prefix = "Enquiry"; //Use this if you want to have a prefix before the subject
if (!isset($_GET['action'])) {
    die("You must not access this page directly!"); //Just to stop people from visiting get-in-touch.php normally
}
else {
    /* Now lets trim up the input before sending it */
    $fname = trim($_GET['fname']); //The senders name
    $lname = trim($_GET['lname']); //The senders lname
    $email_id = trim($_GET['email_id']); //The senders email id
    $pphone = trim($_GET['pphone']); //The senders phone
    $cname = trim($_GET['cname']); //The senders message
    $subject = trim($_GET['subject']); //The senders subject
    $message = "Name: " . $fname . "\n Address: " . $lname . "\n Email: " . $email_id . "\n Phone: " . $pphone . "\n Commient: " . $cname . "\n subject: " . $subject;
    $headers = "From: " . $email_id . "";
    // $headers .= 'Bcc: name@email.com' . "\r\n";
    mail($to, $subject, $message, $headers); //a very simple send
    echo 'Thank you ' . $name . ', your email has been sent.';
    // now lets update the "contactarea" div on the contact.html page. The contactarea| tell's the javascript which div to update.
}
