PHP contact form submits but does not send mail - php

Question

I recently made a website using HTML, CSS, and JS. Since I don't know PHP, I am stuck at building the contact form where it is vital on the website. I learned a bit from YouTube tutorials and have the following HTML & PHP code:
<div class="contact_form">
<form action="/action_page.php">
<input type="text" id="name" name="name" placeholder="Name*">
<input class="contact_even" type="text" id="email" name="email" placeholder="Email id*">
<input type="text" id="phone" name="phone" placeholder="Phone No.">
<input class="contact_even" type="text" id="city" name="city" placeholder="City">
<textarea id="subject" name="subject" placeholder="How Can We Help You?"></textarea>
<input type="submit" value="Submit">
</form>
</div>
<?php
if (isset($_POST['submit'])) {
$name = $_POST['name'];
$mailFrom = $_POST['email'];
$phone = $_POST['phone'];
$city = $_POST['city'];
$message = $_POST['message'];
$mailTo = 'example#something.in';
$headers = 'From: '.$mailFrom;
$txt = $name.'('.$phone.') from '.$city.' says:\n\n'.$message;
$headers = "MIME-VERSION: 1.0" . "\r\n";
$headers .= "Content-type:text/html;charset=UTF-8" . "\r\n";
mail($mailTo, $headers, $txt);
header("Location: index.html?mailsent");
}
?>
Why do I need the MIME and content-type headers at the bottom as that bit I added from another tutorial.
When I use the form and try sending the message, I get the "?mailsent" after the URL but I receive no email which is a professional plan by GoDaddy.
They are also hosting my website. I contacted them to know whether the server allows me to make my contact form with the plan I have and they said yes. So, I must be missing something important here.

Answer 1

refer to the documentation of mail function
there are 3 required parameter : email destination (to), subject and the message, and two additional options are: headers and parameters.
your code didnt respect that, because you missing to add the subjuct as parameter.
and you get ?mailsent because you use header("Location: index.html?mailsent") without any test if the email send successfully or not.
i suggest you to replace the last two lines of your php code with this
$subject = "some subject"; // you can replace it with $subject = $_POST["subject"]
$result = mail($mailTo, $subject , $txt,$headers);
if ($result){
// mail send successfully
header("Location: index.html?mailsent");
} else {
// error
}
EDIT:
you can get the error message with error_get_last() function.
thanks to https://stackoverflow.com/a/20203870/195835
$subject = "some subject"; // you can replace it with $subject = $_POST["subject"]
$result = mail($mailTo, $subject , $txt,$headers);
if ($result){
// mail send successfully
header("Location: index.html?mailsent");
} else {
print_r(error_get_last());
}

Answer 2

You are missing the form action, So PHP doesn't know what to do with your variable data.Try adding method="post" inside <form> tag. Like this
<div class="contact_form">
<form action="/action_page.php" method="post">
<input type="text" id="name" name="name" placeholder="Name*">
<input class="contact_even" type="text" id="email" name="email" placeholder="Email id*">
<input type="text" id="phone" name="phone" placeholder="Phone No.">
<input class="contact_even" type="text" id="city" name="city" placeholder="City">
<textarea id="subject" name="subject" placeholder="How Can We Help You?"></textarea>
<input type="submit" value="Submit">
</form>
</div>
And also. If you use your computer as localhost(using xampp , wamp, or something without a hosting service) You have to make some changes to the config files.
Also try this modified php code
<?php
if (isset($_POST['submit'])) {
$name = $_POST['name'];
$mailFrom = $_POST['email'];
$phone = $_POST['phone'];
$city = $_POST['city'];
$message = $_POST['message'];
$title = "replace this";
$mailTo = 'support#udichi.in';
$txt = $name.'('.$phone.') from '.$city.' says:\n\n'.$message;
$headers = 'From: '.$mailFrom . PHP_EOL .'Reply-To:' .$mailFrom . PHP_EOL . 'X-Mailer: PHP/' . phpversion();
mail($mailTo,$title,$txt,$headers);
header("Location: index.html?mailsent");
}
?>
