我正在编写我自己的第一个网站。有一个部分，您可以输入您的姓名，邮件和消息给我。通过单击“发送消息”，该消息应发送到我的个人邮件。网站访问者应该通过弹出“消息已成功发送”或类似的方式收到提醒。遗憾的是，当点击“发送消息”时，会打开另一个网站，说明“发送消息失败”。任何帮助都非常感谢。
HTML：
<form action="untitled.php" method="post" target="self">
<p><input class="w3-input w3-border" type="text" id="name" name="name" placeholder="Name" required name="Name"></p>
<p><input class="w3-input w3-border" type="email" id="email" name="email" placeholder="Email" required name="Email"></p>
<p><textarea id="message" type="text" name="message" required placeholder="Message" rows="6" cols="30" ></textarea>
</p>
<button class="w3-button w3-black" type="submit" name="submit" value="submit">
<i class="fa fa-paper-plane"></i> Sende Nachricht
</button>
</p>
</form>
php：代码
<?php
$posted = false;
if( $_POST ) {
$posted = true;
$to = '[email protected]';
$name = $_POST['name'];
$mail_from = $_POST['email'];
$subject = 'Message sent from website';
$message = $_POST['message'];
$header = "From: $name <$mail_from>";
$result = $_POST['name'] == "danny"; // Dummy result

欢迎来到stackoverflow :)我在下面测试了你的公式（你可以点击运行）并且看起来有效，但是你需要untitled.php或者你可以将它重命名为email.php以使其更具体，即email.php是一个代码只发送电子邮件:)
在email.php（目前无名字.php）中，请看看这个帖子How to send an email using PHP?
或将此代码复制粘贴到email.php（当前为untitled.php）
<?php
$to = '[email protected]'; //your email
$subject = 'from my website - email form';
$message = $_POST['message'];
$headers = 'From: '.$_POST['email']. "\r\n" .
'Reply-To: [email protected]' . "\r\n" .
'X-Mailer: PHP/' . phpversion();
mail($to, $subject, $message, $headers);
?>
//thank you message
<div>Thanks for your message, I'll answer your email as soon as i can. best regards <a href="/">back »</a></div>
<form action="untitled.php" method="post" target="self">
<p><input class="w3-input w3-border" type="text" id="name" name="name" placeholder="Name" required name="Name"></p>
<p><input class="w3-input w3-border" type="email" id="email" name="email" placeholder="Email" required name="Email"></p>
<p><textarea id="message" type="text" name="message" required placeholder="Message" rows="6" cols="30" ></textarea>
</p>
<button class="w3-button w3-black" type="submit" name="submit" value="submit">
<i class="fa fa-paper-plane"></i> Sende Nachricht
</button>
</p>
</form>如何执行这两种方法的示例 - 传统表单提交和ajax。
<?php
ob_clean();
$payload=array();
if( $_SERVER['REQUEST_METHOD']=='POST' && !empty( $_POST['submit'] ) ){
/* for ajax & standard form submissions */
$args=array(
'name' => FILTER_SANITIZE_STRING,
'email' => FILTER_SANITIZE_EMAIL,
'message' => FILTER_SANITIZE_STRING
);
$_POST=filter_input_array( INPUT_POST, $args );
/* Have any additional fields been injected into the POST request? */
foreach( $_POST as $field => $value ){
if( !in_array( $field, array_keys( $args ) ) )exit( sprintf( 'unknown parameter "%s"', $field ) );
}
/* Are all the required fields in the POST array? */
foreach( array_keys( $args ) as $field ){
if( !in_array( $field, array_keys( $_POST ) ) )exit( sprintf('Empty or missing parameter "%s"',$field ) );
}
/* assign fields to variables */
extract( $_POST );
/*
check the validity of the email address -
doesn't actually determine if this is a genuine email though
*/
$email = filter_var( $email, FILTER_VALIDATE_EMAIL );
if( $email ){
$to = '[email protected]';
$from = $email;
$subject = 'Message sent from website';
$headers = sprintf( 'From: %s<%s>', $name, $email );
$status=@mail( $to, $subject, $message, $headers );
$payload['email']=$email;
$payload['status']=$status;
$payload['message']=$message;
$payload['method']='FORM';
}
if( !empty( $_SERVER['HTTP_X_REQUESTED_WITH'] ) && $_SERVER['HTTP_X_REQUESTED_WITH']=='XMLHttpRequest' ){
header('Content-Type: application/json');
$payload['method']='AJAX';
exit( json_encode( $payload ) );
