提交并刷新后显示一条消息

如何解决提交并刷新后显示一条消息

我试图在提交表单后显示一条消息，我可以提交表单，然后刷新页面，但不确定如何在刷新后添加消息。

我不了解PHP，因此很抱歉，它是显而易见的答案

谢谢

我的html和PHP（如果需要）

<form action="action.php" method="POST" target="my_iframe" onsubmit="setTimeout(function(){window.location.reload();},10);">
                    
                        <input type="text" id="name" name="name" placeholder="name" required="required">
    
                        <input type="email" id="email" name="email" placeholder="email" required="required">
                
                        <input type="tel" id="phone" name="phone" placeholder="phone">
                        
                        <div class="form-row" style="display:none;"><input type="hidden" name="url" placeholder="URL"></div>
                
                        <textarea id="message" name="message" placeholder="message" style="height:200px"  required="required"></textarea>
                        
                        <input id="submit" type="submit" value="submit">
                        
                    </form>
                    <iframe name="my_iframe" width="1" height="1" style="border:none"></iframe>



<?php

$to = '[e-mail]';
$subject = 'New Message Recieved!';
$from = $_POST['email'];
$phone = $_POST['phone'];
$message = $_POST['message'];
$name = $_POST['name'];

//check honeypot
    if( !empty( $honeypot ) ) {
        echo 'There was a problem';
    }
 
// To send HTML mail,the Content-type header must be set
$headers  = 'MIME-Version: 1.0' . "\r\n";
$headers .= 'Content-type: text/html; charset=iso-8859-1' . "\r\n";
 
// Create email headers
$headers .= 'From: '.$from."\r\n".
    'Reply-To: '.$from."\r\n" .
    'X-Mailer: PHP/' . phpversion();
 
// Compose a simple HTML email message
$message = "$message \r\n |
                From $name \r\n |               
                Tel: $phone";


 
// Sending email
if(mail($to,$subject,$message,$headers)){
    echo 'Your message has been sent successfully.';
} else{
    echo 'Unable to send email. Please try again.';
}

?>

解决方法

更新您的php发送电子邮件到此

    if (mail($myEmail,$subject,$message)){
     $success = "Message sent successful";
    }else{
     $success = "Message Sending Failed.";
    }

然后在您的html代码中添加此php代码，并添加此代码以显示消息。将其放在表单html标签顶部。

<?php
 if (isset($success)){ echo "<div>" . $success . "</div>";}
?>

如果愿意，您甚至可以在邮件上添加一些样式。
