有人可以帮忙解决这个问题吗，它总是说不明的索引和变量。是从文本字段获取数据的脚本？我正在尝试从网站发送电子邮件，但这一直在显示，无法发送电子邮件

   <?php

         $to ='jasoncas02@yahoo.com.ph';    
         $subject = 'Customer Inquiry';            

         $name = $_POST['name'];             
         $email = $_POST['email'];
         $tel = $_POST['tel'];
         $message = $_POST['message'];

         $body = <<<EMAIL
            Hi! My name is $name.
         $message

         from: $name 
         $email
         $tel

         EMAIL;

         $header = "from:$email";

         if($_POST){
         if($name == ' ' || $email == ' ' || $message == ' '|| $tel == ' '){$feedback = 'Fill out all the fields';
         }

         mail($to, $subject, $body, $header);
         $feedback = "Thanks for you Email, We will answer your email as soon as possible";
         }
         }

           </div>
           </body>

Answer 1

像这样制作$body变量

 $body = "
          Hi! My name is ".$name."<br/>"
          ".$message."<br/>

         from: ".$name."<br/>" 
         .$email."<br/>"
         .$tel."<br/>"

          ";

Answer 2

使用前检查$ _POST。

if(!empty($_POST) && isset($_POST['name']) && isset($_POST['tel']) && isset($_POST['email']) && isset($_POST['message'])){
//send mail code
}

未识别的变量和不明的索引
