Please help me resolve this issue. Any help will be highly appreciable. I'm attaching herewith a part of my contact.php code and my mail.php code. Thank You

contact.php

In the contact.php file

name="submit" is missing for the submit button.

This line should be:

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

Explanation: Currently the

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

always evaluates to FALSE as POST['submit'] is empty so it continues at the header()...

################

try this code as mail.php and tell us what happens;-)

<?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;

?>

Here i have the new contact.php file - just copy paste this

<!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">

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

                        <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>

you should add name to your button

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

also as you're redirecting by changing header it won't show you the alert as alert was on different page.

try this code

<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>

and below this write your php code in same file

<?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>";
  }
}
?>

Replace

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

To

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