Contactform.php not sending all inputs - php

Question

I have a contact form that is working fine, it sends the email except that it doesn't post the email address of the person that sends it. I have no idea why, I tried changing the $from variable and nothing changes. Is there something obvious I am missing?
It is the input with the id c_email which is put into the $from variable that I do not receive in the emails sent by this form.
My contactform.php:
<?php
// Contact
$to = 'myemail#gmail.com';
$subject = 'Portfolio ContactForm';
if(isset($_POST['c_name']) && isset($_POST['c_email']) && isset($_POST['c_message'])){
$name = $_POST['c_name'];
$from = $_POST['c_email'];
$message = $_POST['c_message'];
if (mail($to, $subject, $from, $name, $message)) {
$result = array(
'message' => 'Sent, thanks!',
'sendstatus' => 1
);
echo json_encode($result);
} else {
$result = array(
'message' => 'Ooops, problem..',
'sendstatus' => 1
);
echo json_encode($result);
}
}?>
On my html page:
<form id="contact-form" role="form">
<div class="form-group">
<label class="sr-only" for="c_name">Name</label>
<input type="text" id="c_name" class="form-control" name="c_name" placeholder="Nom">
</div>
<div class="form-group">
<label class="sr-only" for="c_email">Email address</label>
<input type="email" id="c_email" class="form-control" name="c_email" placeholder="E-mail">
</div>
<div class="form-group">
<textarea class="form-control" id="c_message" name="c_message" rows="7" placeholder="Votre message"></textarea>
</div>
<button type="submit" class="btn btn-custom-1">
<i class="fa fa-bullhorn icon-before"></i> Envoyer
</button>
</form>

Your values is not posting because in your form you not mention method="POST".Just try like this.it should work
<form id="contact-form" role="form" action="" method="POST">
<div class="form-group">
<label class="sr-only" for="c_name">Name</label>
<input type="text" id="c_name" class="form-control" name="c_name" placeholder="Nom">
</div>
<div class="form-group">
<label class="sr-only" for="c_email">Email address</label>
<input type="email" id="c_email" class="form-control" name="c_email" placeholder="E-mail">
</div>
<div class="form-group">
<textarea class="form-control" id="c_message" name="c_message" rows="7" placeholder="Votre message"></textarea>
</div>
<button type="submit" class="btn btn-custom-1">
<i class="fa fa-bullhorn icon-before"></i> Envoyer
</button>
</form>
<script>
$('button').click(function() {
var c_name = $("#c_name").val();
var c_email = $("#c_email").val();
var c_message = $("#c_message").val();
$.ajax({//create an ajax request to load_page.php
type: "POST",
url: "assets/php/contactForm.php",
data:{"c_name":c_name,"c_email":c_email,"c_message":c_message},
success: function(data) {
if (data) {
alert(data);
}
else {
alert('Successfully not posted.');
}
}
});
});
</script>
