我创建了一个带有 html 和 php 代码的 web php 网页，见下文。
当我提交表单时，它会向我发送一封电子邮件，并显示成功或失败消息。所以，一切正常。
我的问题:我想使成功或失败消息弹出或成为模态，但我不知道该怎么做。我应该在哪里更改代码并添加模态？
我在顶部有 php，然后是我的 HTML 表单。我的表单还有 google recaptcha 验证工具。我只想添加一个模式，但我不知道如何以及在哪里添加代码。
<?php
error_reporting(0);
$msg="";
if (isset($_POST['submit'])) {
$to = "aleciadeklerk.119@gmail.com";
$subject = "Form Submission";
$name = $_POST['name'];
$email = $_POST['email'];
$message = $_POST['message'];
$check = $_POST['check'];
$msgBody = 'Name: '.$name.'Message: '.$message.'Subscribe: '.$check.'E-mail: '.$email;
$headers = 'From: '.$email;
$secretKey = "6LdXbq8UAAAAAM1B79Yz2IPgcTuIynBXeJMF2ZLY";
$responseKey = $_POST['g-recaptcha-response'];
$url = "https://www.google.com/recaptcha/api/siteverify?secret=$secretKey&response=$responseKey";
$response = file_get_contents($url);
$response = json_decode($response);
if ($response->success) {
if (mail($to, $subject, $msgBody, $headers)) {
$msg="Message sent successfully!";
}
else {
$msg="Failed to send the message. Please try again.";
}
}
else {
$msg="Verification Failed";
}
}
?>

我的目标是点击提交按钮，然后弹出一个带有成功或失败消息的模式。
最佳答案
如果您想使用模态作为信息消息，请将模态放在 html 中的 body 标记之后，然后在事件成功或失败后使用 javascript 调用它。
用于模式的 javascript:$('#myModal').modal(options).
或者如果你想要更简单的方式，你可以使用 javascript alert() 来通知成功或失败的事件
