【问题描述】：

我完全不明白为什么我会在这段代码中收到此错误：

$finalmessage = "
From:$_POST['name']
Email:$_POST['email']
Message:$_POST['message']
";

下面是整个邮件 php 代码：

<?php

$name = $_POST['name'];
$surname = $_POST['surname'];
$email = $_POST['email'];
$message = $_POST['message'];
$support_address = "info@bkslegal";
$headers = "From: ".$email;
$header2 = "From: ".$support_address;
$finalmessage = "
From:$_POST['name']
Email:$_POST['email']
Message:$_POST['message']
";

if ( $name == "")

{   
}
else
{
mail("$support_address","finalmessage",$headers);
$result = "Your message has been sent succesfully!" 

mail("$email","Thank you for contacting us!","We will soon be in contact with you!",$header2);  
}
?>

Reference - What does this error mean in PHP?的可能重复
当整个复杂变量构造未包含在 {} 中时，尝试使用带引号的键引用数组值以在双引号字符串内进行插值时，最常遇到此错误。 stackoverflow.com/questions/12769982/…

【解决方案1】：

我看到你的参数写错了。你写道：

mail("$support_address","finalmessage",$headers);

应该是：

mail ($support_address, $subject, $message, $headers);

并删除此行

//mail("$email","Thank you for contacting us!","We will soon be in contact with you!",$header2);

PHP 邮件SYNTAX 是：

mail ( string $to , string $subject , string $message [, string $additional_headers [, string $additional_parameters ]] )

最终代码：

<?php
$name = $_POST['name'];
$surname = $_POST['surname'];
$email = $_POST['email'];
$support_address = "info@bkslegal";

if($name == "") {
   //show somting error message
}
else
{
    $Message = "From:".$name."<br />";
    $Message .= "Email:".$email."<br />";
    $Message .= "Message:". $_POST['message'];

    $to = $support_address;
    $subject = "new message";

    // To send HTML mail, the Content-type header must be set
    $headers  = 'MIME-Version: 1.0' . "\r\n";
    $headers .= 'Content-type: text/html; charset=iso-8859-1' . "\r\n";

    // Additional headers
    $headers .= 'To: Name <$to>' . "\r\n";
    $headers .= 'From:  $name <$email>' . "\r\n";
    $headers .= 'Cc: birthdayarchive@example.com' . "\r\n";
    $headers .= 'Bcc: birthdaycheck@example.com' . "\r\n";


    if(mail($to, $subject, $Message, $headers)) {
       echo "Your message has been  Sent";
    } else {
       echo "Mesage Error";
    }  
}
?>

注意：使用任何邮件库来防止像PHPMailer这样的标头注入漏洞
