如何在同一頁面上顯示消息？

Question

我對我的表格有一個快速的問題。 提交表單后，您將被定向到頁面，后跟我輸入的文本。問題是我希望將此文本與表單所在的頁面顯示在同一頁面上（名為contact.html），我使用兩個文件，一個是Mail_handler.php，另一個是contact.html。 我已經嘗試了多種方法來修復它，但是由於某種原因，我沒有成功。 我希望你們能幫助我！ 您可以在下面找到HTML和PHP。

 <form method="POST" action="mail_handler.php"> <div class="col-sm-7 slideanim"> <div class="row"> <div class="col-sm-6 form-group"> <input class="form-control" id="name" name="name" placeholder="Naam" type="text" required> </div> <div class="col-sm-6 form-group"> <input class="form-control" id="phone" name="phone" placeholder="Telefoonnummer" type="text" required> </div> <div class="col-sm-12 form-group"> <input class="form-control" id="email" name="email" placeholder="Email" type="email" required> </div> </div> <textarea class="form-control" id="msg" name="msg" placeholder="Bericht" rows="5"></textarea><br> <div class="row"> <div class="col-sm-12 form-group"> <button class="btn btn-default pull-right" id="submit" name="submit" type="submit">Verstuur</button> </div> </div> </div> </div> </div> </div> </form> 

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

    $to='infosyncdevelopment@gmail.com'; // Receiver Email ID, Replace with your email ID
    $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>Bedankt voor uw bericht!"." ".$name.", Wij nemen zo snel mogelijk contact met u op.</h1>";
    }
    else{
        echo "Something went wrong!";
    }
}

最好的方法是使用ajax，但是如果您可能不這樣做，則可以執行以下小技巧：

將contact.html更改為php腳本（也許contact.php）

<?php
    if(isset($_GET['msg'])) echo $_GET['msg'];
?>
<form method="POST" action="mail_handler.php">
      <div class="col-sm-7 slideanim">
      <div class="row">
        <div class="col-sm-6 form-group">
          <input class="form-control" id="name" name="name" placeholder="Naam" type="text" required>
          </div>
          <div class="col-sm-6 form-group">
          <input class="form-control" id="phone" name="phone" placeholder="Telefoonnummer" type="text" required>
        </div> 
          <div class="col-sm-12 form-group">
          <input class="form-control" id="email" name="email" placeholder="Email" type="email" required>
        </div>
      </div>
      <textarea class="form-control" id="msg" name="msg" placeholder="Bericht" rows="5"></textarea><br>
      <div class="row">
        <div class="col-sm-12 form-group">
         <button class="btn btn-default pull-right" id="submit" name="submit" type="submit">Verstuur</button>
        </div>
      </div>
    </div>
  </div>
</div> 
        </div>
    </form> 

在mail_handler.php中，將echo更改為$ msg

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

$to='infosyncdevelopment@gmail.com'; // Receiver Email ID, Replace with your email ID
$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)){


    $msg = "<h1>Bedankt voor uw bericht!"." ".$name.", Wij nemen zo snel mogelijk contact met u op.</h1>";
}
else{
    $msg = "Something went wrong!";
}

header("Location: contact.php?$msg");

} ?>

使用AJAX

    $("form").submit(function(e) {
    e.preventDefault();
    var name = $('#name').val(); 
    // do this for all other input tags
        $.post("file.php" , {x:name , .....} , function(data){
              // do stuff with data , here data is the things echoed/printed by 'file.php'
        });
    });
