php - contact form not getting submitted

Question

On clicking the submit button it is showing submit is not set after the if condition. I guess this message is showing because the form is not getting submitted. I don't know where I'm going wrong kindly help me fix this issue. I'm herewith attaching a part of my contact.php code and mail.php code. Thank you

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>
                            </div>

Answer 1

nothing wrong with your code, i guess you doing a direct request to mail.php

try this code, maybe this help your problem

<?php
if($_POST){ // add condition if http request is POST then process your POST request
    if (isset($_POST['email'])){
    
    echo "submit is set to {$_POST['submit']} and now we send the email<br>";

$to = "[email protected]"; 
$name = $_POST['name'];
$email = $_POST['email'];
$subject = $_POST['subject'];
$message = $_POST['message'];
$message .="
 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; // if POST process has done, script will stop, and code above will not showing
}

?>
