contact form not getting submitted - php

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

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 = "abc#email.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; // if POST process has done, script will stop, and code above will not showing
}
?>
