Question

我有一个简单的联系页面设置表格，我使用php mail()功能通过电子邮件发送这些详细信息。当我提交页面时，它会说：

注意：未定义的变量：第9行的MESSAGE_BODY

有人有任何想法或解决方案吗？

 <?php
 error_reporting(E_ALL); 
if ($_POST["email"]<>'') {
    $ToEmail = 'saif0909@yahoo.com';
    $EmailSubject = 'Get an instant Quote Now';
    $mailheader = "From: ".$_POST["email"]."\r\n";
    $mailheader .= "Reply-To: ".$_POST["email"]."\r\n";
    $mailheader .= "Content-type: text/html; charset=iso-8859-1\r\n";
    $MESSAGE_BODY .= "Company Name".$_POST['companyname']."";
    $MESSAGE_BODY = "First Name: ".$_POST["firstname"]."";
    $MESSAGE_BODY = "Last Name: ".$_POST["lastname"]."";
    $MESSAGE_BODY .= "Email: ".$_POST["email"]."";
    $MESSAGE_BODY = "Phone Number: ".$_POST["phone"]."";
    $MESSAGE_BODY = "Delivery City: ".$_POST["city"]."";
    $MESSAGE_BODY = "Delivery Date: ".$_POST["date"]."";
    $MESSAGE_BODY = "Duration: ".$_POST["duration"]."";
    $MESSAGE_BODY .= "Rental Equipment: ".nl2br($_POST["msg"])."";
    mail($ToEmail, $EmailSubject, $MESSAGE_BODY, $mailheader) or die ("Failure"); 
 ?>

 Your message was sent
<?php
} else {
?>

Answer 1

使用isset。 Fisrt行应该是：

if (isset($_POST["email"]) && $_POST["email"] != "") {

这将触发＆amp;＆amp; amp;＆amp;如果＆＃34;电子邮件＆＃34;并且第二个条件不会导致错误字段未发送。

Answer 2

请在php脚本的顶部添加$MESSAGE_BODY=''。有点像这样。

<?php
 error_reporting(E_ALL); 
if (isset($_POST["email"])) {
    $MESSAGE_BODY='';  //<-- this line
    $ToEmail = 'saif0909@yahoo.com';
    $EmailSubject = 'Get an instant Quote Now';
    $mailheader = "From: ".$_POST["email"]."\r\n";
    $mailheader .= "Reply-To: ".$_POST["email"]."\r\n";
    $mailheader .= "Content-type: text/html; charset=iso-8859-1\r\n";
    $MESSAGE_BODY .= "Company Name".$_POST['companyname']."";
    $MESSAGE_BODY = "First Name: ".$_POST["firstname"]."";
    $MESSAGE_BODY = "Last Name: ".$_POST["lastname"]."";
    $MESSAGE_BODY .= "Email: ".$_POST["email"]."";
    $MESSAGE_BODY = "Phone Number: ".$_POST["phone"]."";
    $MESSAGE_BODY = "Delivery City: ".$_POST["city"]."";
    $MESSAGE_BODY = "Delivery Date: ".$_POST["date"]."";
    $MESSAGE_BODY = "Duration: ".$_POST["duration"]."";
    $MESSAGE_BODY .= "Rental Equipment: ".nl2br($_POST["msg"])."";
    mail($ToEmail, $EmailSubject, $MESSAGE_BODY, $mailheader) or die ("Failure"); 
 ?>

Answer 3

试试这个

的error_reporting（E_ALL）;
  if（$ _POST [＆＃34; email＆＃34;]＆lt;＆gt;＆＃39;＆＃39;）{
     $ ToEmail =＆＃39; saif0909@yahoo.com' ;;
     $ EmailSubject =＆＃39;立即获取报价＆＃39;;
     $ mailheader =＆＃34;来自：＆＃34;。$ _ POST [＆＃34; email＆＃34;]。＆＃34; \ r \ n＆＃34;;
     $ mailheader。=＆＃34;回复：＆＃34;。$ _ POST [＆＃34; email＆＃34;]。＆＃34; \ r \ n＆＃34;;
     $ mailheader。=＆＃34;内容类型：text / html;字符集= ISO-8859-1 \ r \ n＆＃34 ;;
     $ MESSAGE_BODY =＆＃39;＆＃39;;
      $ MESSAGE_BODY。=＆＃34;公司名称＆＃34;。$ _ POST [＆＃39;公司名称＆＃39;]。＆＃34;＆＃34 ;;
     $ MESSAGE_BODY。=＆＃34;名字：＆＃34;。$ _ POST [＆＃34;名字＆＃34;]。＆＃34;＆＃34 ;;
     $ MESSAGE_BODY。=＆＃34;姓氏：＆＃34;。$ _ POST [＆＃34;姓氏＆＃34;]。＆＃34;＆＃34 ;;
     $ MESSAGE_BODY。=＆＃34;电子邮件：＆＃34;。$ _ POST [＆＃34;电子邮件＆＃34;]。＆＃34;＆＃34 ;;
     $ MESSAGE_BODY。=＆＃34;电话号码：＆＃34;。$ _ POST [＆＃34;电话＆＃34;]。＆＃34;＆＃34 ;;
     $ MESSAGE_BODY。=＆＃34;交货城市：＆＃34;。$ _ POST [＆＃34; city＆＃34;]。＆＃34;＆＃34 ;;
     $ MESSAGE_BODY。=＆＃34;交货日期：＆＃34;。$ _ POST [＆＃34; date＆＃34;]。＆＃34;＆＃34 ;;
     $ MESSAGE_BODY。=＆＃34;持续时间：＆＃34;。$ _ POST [＆＃34;持续时间＆＃34;]。＆＃34;＆＃34 ;;
     $ MESSAGE_BODY。=＆＃34;租赁设备：＆＃34; .nl2br（$ _ POST [＆＃34; msg＆＃34;]）。＆＃34;＆＃34 ;;
     邮件（$ ToEmail，$ EmailSubject，$ MESSAGE_BODY，$ mailheader）或死亡（＆＃34;失败＆＃34;）;

Answer 4

您可以在MESSAGE_BODY的第一个声明中删除连接，并将连接（。=）添加到将文本添加到$ MESSAGE_BODY的所有其他行。 $ MESSAGE_BODY的第一个应该是：$ MESSAGE_BODY = ....其余的应该是这样的 $ MESSAGE_BODY。= ...

注意：未定义的变量：第9行中的MESSAGE_BODY
