提交表单数据时 php 脚本显示空白页

Question

这是我的 html 和 PHP 代码，当我提交表单数据时，它将我定位到空白 window 那里没有报告错误也没有数据发到邮箱了，需要进一步说明我的PHP显示错误和显示启动错误都在。

HTML

 <!-- form start  -->
        <form action="mail_handler.php" method="post" name="form" class="form-box">


         <div class="col-sm-6">
          <div class="form-group">

           <input type="text" name="name" class="form-control" placeholder="Your Name">
         </div>
       </div>

       <div class="col-sm-6">
         <div class="form-group">
           <input type="email" name="email" class="form-control" placeholder="Your Email">
         </div>
       </div>

       <div class="col-sm-6">
        <div class="form-group">
          <input type="tel" name="phone" class="form-control" placeholder="Your Phone Number">
        </div>

        <div class="col-sm-12">
         <div class="textarea-message form-group">
           <textarea name="msg" class="textarea-message form-control" placeholder="Your Message" rows="5">

           </textarea>
         </div>
       </div>


       <div class="text-center">      
        <button type="submit" class="load-more-button">submit
        </button>
      </div>

    </form>

PHP

    <?php
            if(isset($_POST['submit']))
            {
            $name=$_POST['name'];
            $email=$_POST['email'];
            $phone=$_POST['phone'];
            $msg=$_POST['msg'];

            $to='xyz@gmail.com'; 
            $subject='Form Submission';
            $message="Name :".$name."\n"."Phone :".$phone."\n"."Wrote the following :"."\n\n".$msg;
            $headers="From: ".$email;

            if(mail($to, $subject, $message, $headers))
            {
            echo "<h1>Sent Successfully! Thank you"." ".$name.", We will contact you shortly!</h1>";
            }
            else
            {
            echo "Something went wrong!";
            }
            }
            ?>

Answer 1

在按钮输入中添加name="submit"

Answer 2

而不是

<button type="submit" class="load-more-button">submit
</button>

使用

<button type="submit" name="submit" class="load-more-button">submit
</button>

注意添加的name="submit"
