提交电子邮件表单后，我想保持在同一页面上，并像成功一样发送消息

Question

我希望在提交电子邮件信息后保持在同一页面上，而不是将我重定向到新页面。

这是我的 html 代码：

<form method="post" action="index.php" id="formaa" accept-charset="UTF-8">
    <input name="name" placeholder="Name" id="aa">
    <input name="email" type="email" placeholder="E-mail" id="aa">      
    <textarea name="message" placeholder="Message"></textarea>      
    <input name="human" placeholder="2+2=" id="ab">
    <input id="submit" name="submit" type="submit" value="Submit">
</form>

这是 PHP 代码：

<?php
$name = $_POST['name'];
$email = $_POST['email'];
$message = $_POST['message'];
$headers = 'From: PappuLighting'; 
$to = '[e-mail]'; 
$subject = 'Hello';
$human = $_POST['human'];
$headers = "MIME-Version: 1.0" . "rn";
$headers .= "Content-type:text/html;charset=UTF-8" . "rn";
$body = "From: $namen E-Mail: $emailn Message:n $message";
if ($_POST['submit'] && $human == '4') {                 
if (mail ($to, $subject, $body, $headers)) { 
echo '<p>Your message has been sent!</p>';
} else { 
echo '<p>Something went wrong, go back and try again!</p>'; 
} 
} else if ($_POST['submit'] && $human != '4') {
echo '<p>You answered the anti-spam question incorrectly!</p>';
}
?>

Answer 1

尝试这样 ==> 将 php 和 html 代码放在同一个文件中并action=""

<?php
if(isset($_POST['submit'])){
$name = $_POST['name'];
$email = $_POST['email'];
$message = $_POST['message'];
$headers = 'From: PappuLighting'; 
$to = '[e-mail]'; 
$subject = 'Hello';
$human = $_POST['human'];
$headers = "MIME-Version: 1.0" . "rn";
$headers .= "Content-type:text/html;charset=UTF-8" . "rn";
$body = "From: $namen E-Mail: $emailn Message:n $message";
if ($_POST['submit'] && $human == '4') {                 
if (mail ($to, $subject, $body, $headers)) { 
$messageSuccess =  '<p>Your message has been sent!</p>';
} else { 
$messageerror =  '<p>Something went wrong, go back and try again!</p>'; 
} 
} else if ($_POST['submit'] && $human != '4') {
$messageerror = '<p>You answered the anti-spam question incorrectly!</p>';
}
}
?>
    <?php  
    if(isset($messageSuccess))
    echo $messageSuccess;
   else if(isset($messageSuccess))
    echo $messageerror;
    ?>
<form method="post" action="" id="formaa" accept-charset="UTF-8">
    <input name="name" placeholder="Name" id="aa">
    <input name="email" type="email" placeholder="E-mail" id="aa">      
    <textarea name="message" placeholder="Message"></textarea>      
    <input name="human" placeholder="2+2=" id="ab">
    <input id="submit" name="submit" type="submit" value="Submit">
</form>

你可以

通过使用一个使ajax变得简单的框架来使用ajax调用，如jQuery或AngularJS。 在这种情况下，在服务器端，您应该创建 REST APi 端点来发送电子邮件。
