PHP在同一页面上发送带有响应的电子邮件

代码执行，但我没有收到错误消息或成功消息，你知道为什么这不起作用吗

<?php 

if(isset($_POST['action'])=='submitfunc') {
    submitfunc(); 
}
else {} //show form $fromeml = "From:".$_POST['demo-email'].' \r\n';

if(isset($_POST['demo-copy'])==true){
    $ccemail = "Cc:".$_POST['demo-email'].' \r\n'; 
}
else {
    $ccemail= "Cc: \r\n";
} 

function submitfunc() {

    $to = "me@mywebsite.net";    
    $subject = "This is subject";    
    $message = $_POST['demo-name']."<br><br>";    
    $message .= $_POST['demo-message'];    
    $header = $fromeml;    
    $header = $ccemail; 
    $header .= "MIME-Version: 1.0\r\n";    
    $header .= "Content-type:    text/html\r\n";
    $retval = mail ($to,$subject,$message,$header);   
    if( $retval == true ) {
        echo <strong>"Message sent successfully...";</strong>    
    } 
    else {
        echo "Message could not be sent...";    
    }  
}


?>

另外，这里是上面正文中的表单HTML代码。我使用name作为在post变量中查找的函数

                    <form method="post" action="?action=submitfunc">
                        <div class="row uniform 50%">
                            <div class="6u 12u$(3)">
                                <input type="text" name="demo-name" id="demo-name" value="" placeholder="Name" />
                            </div>
                            <div class="6u$ 12u$(3)">
                                <input type="email" name="demo-email" id="demo-email" value="" placeholder="Email" />
                            </div>
                            <div class="12u$">

                            </div>
                            <div class="6u 12u$(2)">

您的代码中有一个输入错误，

打开和关闭标记在echo命令之外：

echo <strong>"Message sent successfully...";</strong>

最后，我用另一个版本自己解决了这个问题，该版本基本上将表单操作设置为空白，并在isset（$_POST['submit']）{上触发，如下所示：

<?php 



if(isset($_POST['submit'])) {
    $to = "my@emladdress.com"; // this is your Email address
    $from = $_POST['demo-email']; // this is the senders Email address
    $first_name = $_POST['demo-name'];
    $last_name = $_POST['demo-priority'].label;
    $subject = "Form submission for ".$_POST['demo-category'];
    $subject2 = "Copy of your form submission for ".$_POST['demo-category'];
    $message = "<h1>".$first_name . "</h1>" . $last_name . " wrote the following:" . "\n\n" . $_POST['demo-message'];
    $message2 = "Here is a copy of your message " . $first_name . "\n\n" . $_POST['demo-message'];
    $headers = "From:" . $from;
    $headers2 = "From:" . $to;
$headers = "MIME-Version: 1.0" . "\r\n";
$headers .= "Content-type:text/html;charset=UTF-8" . "\r\n";
$headers2 = "MIME-Version: 1.0" . "\r\n";
$headers2 .= "Content-type:text/html;charset=UTF-8" . "\r\n";
    mail($to,$subject,$message,$headers);
    mail($from,$subject2,$message2,$headers2); // sends a copy of the message to the sender
    echo "Mail Sent. Thank you " . $first_name . ", we will contact you shortly.";
    }


?>

此版本与上面的表单一起工作，并将电子邮件设置为html，这非常方便，而且都是从一个页面开始的！

您在本地运行吗？您收到电子邮件了吗？我没有使用此功能收到电子邮件，我是在单独的页面上收到的，并且能够使用纯字符串调用通用函数并收到电子邮件，因此我知道这与我的代码有关而不是我的配置它在代码本身中，所以在提交时？是的，这个php在主体下面，但在其他地方阅读时，我希望它会基于…n=“？action=submitfunc”运行>好的，我按照你的建议改变了这个值，但它没有改变anything@Frankenmint所以你仍然没有收到任何文本？错误消息呢？没有，和以前一样，现在要尝试Dorvala的建议，所以你只是在原始问题中发布了错误的形式？为什么你没有调试

$\u post

内容？

error_reporting(E_ALL);
ini_set('display_errors', '1');

<?php 



if(isset($_POST['submit'])) {
    $to = "my@emladdress.com"; // this is your Email address
    $from = $_POST['demo-email']; // this is the senders Email address
    $first_name = $_POST['demo-name'];
    $last_name = $_POST['demo-priority'].label;
    $subject = "Form submission for ".$_POST['demo-category'];
    $subject2 = "Copy of your form submission for ".$_POST['demo-category'];
    $message = "<h1>".$first_name . "</h1>" . $last_name . " wrote the following:" . "\n\n" . $_POST['demo-message'];
    $message2 = "Here is a copy of your message " . $first_name . "\n\n" . $_POST['demo-message'];
    $headers = "From:" . $from;
    $headers2 = "From:" . $to;
$headers = "MIME-Version: 1.0" . "\r\n";
$headers .= "Content-type:text/html;charset=UTF-8" . "\r\n";
$headers2 = "MIME-Version: 1.0" . "\r\n";
$headers2 .= "Content-type:text/html;charset=UTF-8" . "\r\n";
    mail($to,$subject,$message,$headers);
    mail($from,$subject2,$message2,$headers2); // sends a copy of the message to the sender
    echo "Mail Sent. Thank you " . $first_name . ", we will contact you shortly.";
    }
