[英]Alert message on sending email not showing up
在通过单击发送消息按钮发送 email 时，应显示一个警告框，但它既没有显示查询发送成功，也没有显示 email 未发送，我不知道我哪里出错了。 请帮我解决这个问题。 任何帮助都将是非常可观的。 我附上我的部分联系人。php 代码和我的邮件。php 代码。 谢谢你
联系方式。php
<form id="contact-form" method="POST" action="mail.php">
<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" type="submit" value="submit" name="submit">Send Message</button>
</div>
</form>
mail.php
<?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, $message)){
echo "<script>alert('Enquiry sent successfully!');</script>";
}
else
{
echo "<script>alert('Mail was not sent. Please try again later');</script>";
}
}
header('Location: https://imatrixautomation.com/contact.php');
exit;
?>
在contact.php文件中
提交按钮缺少name="submit" 。
这一行应该是：
<button class="btn btn-primary solid blank button" id="btn" type="submit" name="submit" value="submit">Send Message</button>
解释：目前
if (isset($_POST['submit'])){
由于 POST['submit'] 为空，因此始终评估为 FALSE，因此它在 header() 处继续...

尝试将此代码作为 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;
?>
在这里我有新的联系人。php 文件 - 只需复制粘贴即可
<!doctype html>
<html>
<head>
<meta charset="utf-8">
<title>Unbenanntes Dokument</title>
</head>
<body>
<form id="contact-form" method="POST" action="mail.php">
<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" type="submit" name ="submit" value="submit">Send Message</button>
</div>
</form>
</body>
</html>
您应该在按钮上添加名称
<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 header 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>
并在下面将您的 php 代码写在同一个文件中
<?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>";
}
}
?>
代替
<button class="btn btn-primary solid blank button" id="btn" type="submit" value="submit" name="submit">Send Message</button>
至
<input class="btn btn-primary solid blank button" id="btn" type="submit" value="submit" name="submit">
