好的，对于您的表单页面..

<form action="server.php" method="post">
    <h1> Contact us </h1>
    <label for="name">Name:</label>
    <span>Please enter your name</span>
    <p> <input type="text" name="name"> </p>
    <label for="email">Email:</label>
    <span>Please enter a valid email address</span>
    <p> <input type="text" name="email"> </p>
    <label for="subject">Subject:</label>
    <span>Please enter your subject</span>
    <p> <input type="text" name="subject"> </p>
    <label for="message">Message</label>
    <span>Please enter your message</span>
    <p> Message: </p> <p> <textarea rows="4" cols="50" name="message"> </textarea> </p>
    <p> <input type="submit" value="submit"> </p>
</form>

服务器.php页面：

如果您决定更改此页面的名称，请记住在第一页表单的"表单操作"部分中更新名称

.PHP：

$name = $_POST["name"];
$email = $_POST["email"];
$subject = $_POST["subject"];
$message= $_POST["message"];
//Sending information to an email
$to = "khanyasser@live.co.uk";
$from = $email;
$headers = "From: " . $from;
if ($name != '' && $email != '' && $subject != '' && $message != '')
{
    mail($to,$subject,$message,$headers);
    echo "mail sent";
} else {
    echo "Please fill in all of the required fields";
}

如果您有任何问题，请告诉我，我会进一步为您提供帮助，但我认为这应该可以解决您的问题。

你犯了很傻的错误，其实你还没有把<放在form的开头。如果您在php文件中遇到任何错误，请发布它，以便我们为您提供帮助。我在 php 中没有发现任何错误，但我只在 html 语法中发现了错误。我认为您的服务器在压力下被压垮了，请给您的服务器一些时间，然后检查您的电子邮件，我相信您很快就会收到消息。

<form action="server.php" method="post">
    <p> 
        <label for="name">Name:</label>
        <input name="name" id="name" type="text" class="required">
        <span>Please enter your name</span>
    </p>
    <p> 
        <label for="email">Email:</label>
        <input name="email" id="email" type="text" class="required">
        <span>Please enter a valid email address</span>
    </p>
    <p>
        <label for="subject">Subject:</label>
        <input name="subject" id="subject" type="text">
        <span>Please enter your subject</span>
    </p>
    <p>
        <label for="message">Message</label>
        <textarea name="message" id="message" class="required"></textarea>
        <span>Please enter your message</span>
    </p>
    <p class="submit">
        <input type="submit" value="Submit" class="btn-submit" name="send" />
    </p>
</form>

您的服务器.php脚本

<?php
define('FROM', 'F-Sharp Media');
define('RECIPIENT', 'f.ajibade@f-sharpmedia.com');
define('SUBJECT', 'Hello');
if ( ! isset($_POST['send']))
{
    header('Location: form.html');
    die;
}
$errors = array();
if ( ! isset($_POST['name']) || empty($_POST['name']))
    $errors[] = '"name" can not be empty';
if ( ! isset($_POST['email']) || empty($_POST['email']))
    $errors[] = '"email" can not be empty';
if ( ! isset($_POST['message']) || empty($_POST['email']))
    $errors[] = '"message" can not be empty';
if ( ! isset($_POST['human']) || ((int) $_POST['human'] !== 4))
    $errors[] = 'are you human?';
if (count($errors) > 1)
{
    foreach($errors as $error)
        echo $error,"'n";
    die('Aborting due to form errors');
}
$body =<<<MAIL
    From: {$_POST['name']}
    E-Mail: {$_POST['email']}
    Message:
        {$_POST['message']}
MAIL;
$headers = 'From: '.FROM;
if (mail(RECIPIENT, SUBJECT, $body, $headers))
    echo 'Email sent!';
else
    echo 'Failed sending email';

请注意，mail(( 在 php 上需要一些配置.ini

你会更好地使用SwiftMailer，PHPMailer或其他邮件库

如果您尝试从本地主机发送邮件，则必须查看如何从本地主机发送邮件

或

您可以使用 SwiftMailer 发送邮件。它非常简单易用。

还尝试使用SMTP身份验证发送邮件，可能会发生在服务器上发送邮件需要身份验证的情况。

也许这对你有用，试试这个：

require_once('swift/swift_required.php');
$name = $_POST['name'];
$email = $_POST['email'];
$message = $_POST['message'];
$from = 'From: F-Sharp Media'; 
$to = 'f.ajibade@f-sharpmedia.com'; 
$subject = 'Hello';
$body = "From: $name'n E-Mail: $email'n Message:'n $message";
$transport = Swift_SmtpTransport::newInstance('SMTP_HOST', SMTP_PORT)
                  ->setUsername('SMTP_USERNAME')
                  ->setPassword('SMTP_PASSWORD')
                  ;
$mailer = Swift_Mailer::newInstance($transport);
    $message = Swift_Message::newInstance()
                       ->setSubject($subject) // Message subject
                       ->setTo(array($to => 'TO_NAME')) // Array of people to send to
                       ->setFrom(array($email => $name)) // From:
                       ->setBody($body , 'text/html');
if($mailer->send($message)){
    header("Location:email_success.php");
}
else{
    echo 'Some error occurred while sending mail';
    exit;
}
