发送电子邮件的警报消息未显示

Question

在通过单击发送消息按钮发送电子邮件时，应显示一个警报框，但它没有出现，既不显示查询已成功发送，也不显示未发送电子邮件我不知道我要去哪里错误的。请帮我解决这个问题。 任何帮助都将是非常可观的。我附上我的contact.php 代码和mail.php 代码的一部分。 谢谢你

contact.php

<form id="contact-form" method="POST" action="mail.php">
                    <div class="row">
                        <div class="col-md-4">
                            <div class="form-group">

                                <input class="form-control" name="name" id="name" placeholder="" type="text" required>

                </form>

邮件.php

<?php

$name = $_POST['name'];
$email = $_POST['email'];
$subject = $_POST['subject'];
$message = $_POST['message'];
$message .="\r\n from: $email";


if(mail ($to, $subject, $name,  $message)){
    echo "<script>alert('Enquiry sent successfully!');</script>";
   
}
    else
    {
    echo "<script>alert('Mail was not sent. Please try again later');</script>";
    }

Answer 1

替换

<button class="btn btn-primary solid blank button"  id="btn" type="submit" value="submit" name="submit">Send Message</button>

到

<input class="btn btn-primary solid blank button"  id="btn" type="submit" value="submit" name="submit">

Answer 2

你应该给你的按钮添加名字

<button class="btn btn-primary solid blank button"  id="btn" name="submit" type="submit" value="submit">Send Message</button>

同样，当您通过更改标题进行重定向时，它不会向您显示警报，因为警报在不同的页面上。

试试这个代码

<form id="contact-form" method="POST" action="">
<div class="row">
    <div class="col-md-4">
        <div class="form-group">
            <label>Name</label>
            <input class="form-control" name="name" id="name" placeholder="" type="text" required>
        </div>
    </div>
    <div class="col-md-4">
        <div class="form-group">
            <label>Email</label>
            <input class="form-control" name="email" id="email" placeholder="" type="email" required>
        </div>
    </div>
    <div class="col-md-4">
        <div class="form-group">
            <label>Subject</label>
            <input class="form-control" name="subject" id="subject" placeholder="" required>
        </div>
    </div>
</div>
<div class="form-group">
    <label>Message</label>
    <textarea class="form-control" name="message" id="message" placeholder="" rows="10" required></textarea>
</div>
<div class="text-right"><br>
    
    <button class="btn btn-primary solid blank button"  id="btn" name="submit" type="submit" value="submit">Send Message</button>

</div>
</form>

然后在下面写你的 php 代码在同一个文件中

<?php
if(isset($_POST['submit'])) {

$to = "contact@imatrixautomation.com";
$name = $_POST['name'];
$email = $_POST['email'];
$subject = $_POST['subject'];
$message = $_POST['message'];
$message .= "\r\n from: $email";


if(mail($to, $subject, $name, $message)) {
    echo "<script>alert('Enquiry sent successfully!');</script>";
    
}
else {
    echo "<script>alert('Mail was not sent. Please try again later'); 
          </script>";
  }
}
?>

Answer 3

在contact.php文件中

name="submit" 缺少提交按钮。

这一行应该是：

<button class="btn btn-primary solid blank button"  id="btn" type="submit" name="submit" value="submit">Send Message</button>
                

说明： 目前的

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

由于 POST['submit'] 为空，因此始终评估为 FALSE，因此它在 header() 处继续...

试试这个代码作为 mail.php 并告诉我们会发生什么;-)

<?php
if (isset($_POST['submit'])){
    
    echo "submit is set to {$_POST['submit']} and now we send the email<br>";

$to = "contact@imatrixautomation.com"; 
$name = $_POST['name'];
$email = $_POST['email'];
$subject = $_POST['subject'];
$message = $_POST['message'];
$message .="\r\n from: $email";


if(mail ($to, $subject, $name,  $message)){
    echo "Enquiry sent successfully!<br>";
   
}
    else
    {
    echo "Mail was not sent. Please try again later<br>";
    }
} else{

echo"submit is not set<br>"; 
}

echo "after the if condition";


exit;

?> 

这里我有新的contact.php 文件 - 只需复制粘贴即可

<html>
<head>
<meta charset="utf-8">
<title>Unbenanntes Dokument</title>
