提交联系表后显示“谢谢”消息

Question

我的网站上有一个有效的联系表。 提交按钮指向一个正在发送电子邮件的.php 文件（用户看不到此步骤），并将用户再次重定向到联系表单。

单击提交按钮后，我想在屏幕中央发出一条简单的消息。 诸如“感谢您发送申请”之类的内容。

我试图在 php 文件中设置一个变量

$mailSent = 1;

然后在脚本中捕获它

var mailSent = "<?php echo $mailSent; ?>";

然后我想做一个简单的 if 语句和样式。显示消息 cotnainer。 可悲的是它没有成功，我得到了未定义的错误。

if (mailSent == 1) {
    document.querySelector('.thankYouMessage').style.display = 'flex';
}

我想问你是否对如何做有任何想法。 我希望消息看起来像引导模式。

这是我的联系表格：

<div class="contact-form-container">
            <div class="contact-form">
                <form action="contact-form-handler.php" method="POST">

            </div>

这是我的 php Contact-form-handler

<?php

if(isset($_POST['submit'])) {

    $name = $_POST['name'];
    $visitor_email = $_POST['email'];
    $topic = $_POST['topic'];
    $message = $_POST['message'];

    $to = "xyz@xyz.pl";

    $subject = "Tu ".$name.". Wiadomość do xyz";

    $headers = "From: ".$visitor_email;

    $txt = "\nNowa wiadomość od: ".$name."\n\n\nTemat:\n".$topic."\n\n\nWiadomość:\n".$message;

    mail($to, $subject, $txt, $headers);

    header ('Location: contact.php');  

} else {

    header ('location: index.php');

}

?>

Answer 1

您正在尝试添加已解析的 php 代码。 PHP 代码首先被解析为 HTML 代码，然后您将再次将 PHP 代码添加到您的 Z9E13B69D1D2DAACAAAF771 代码中。

添加这个：

$mailSent = false;

如果您的邮件发送成功，请将该变量切换为true 。 然后：

<?php
if($mailSent === true) {
?>
    <div class="success"></div>
<?php
}
?>

编辑：试试这个：

<?php

$mailSent = false;

if(isset($_POST['submit'])) {

        $name = $_POST['name'];
        $visitor_email = $_POST['email'];
        $topic = $_POST['topic'];
        $message = $_POST['message'];

        $to = "marcincelmer95@gmail.com";

        $subject = "Tu ".$name.". Wiadomość do poznanprzeprowadzki.pl";

        $headers = "From: ".$visitor_email;

        $txt = "\nNowa wiadomość od: ".$name."\n\n\nTemat:\n".$topic."\n\n\nWiadomość:\n".$message;

        mail($to, $subject, $txt, $headers);

        $mailSent = true;

}

?>

<?php
if ($mailSent === true) {
?>
<div class="success">Mail is succesfully sent.</div>
<?php
}
?>

Answer 2

现在看起来像这样：

<?php

$mailSent = 0;

echo $mailSent;

if ($mailSent === 1) {
    
    echo "<script>

        function myFunction() {
            document.querySelector('.modal-background').style.display = 'flex';
        };

    </script>";

}

else if ($mailSent === 0) {

    if(isset($_POST['submit'])) {

        $name = $_POST['name'];
        $visitor_email = $_POST['email'];
        $topic = $_POST['topic'];
        $message = $_POST['message'];

        $to = "marcincelmer95@gmail.com";

        $subject = "Tu ".$name.". Wiadomość do poznanprzeprowadzki.pl";

        $headers = "From: ".$visitor_email;

        $txt = "\nNowa wiadomość od: ".$name."\n\n\nTemat:\n".$topic."\n\n\nWiadomość:\n".$message;

        mail($to, $subject, $txt, $headers);

        $mailSent = 1;  

    } 

}

else {

}

?>

程序回显 $mailSent = 0，但尽管它正确发送了 email，但它并没有覆盖 $mailSent 变量...

我是一个初学者，所以我有生以来第一次看到这个错误，很抱歉在某些情况下无知。 我很想学习框架，但我觉得现在理解这一切还为时过早。
