The form doesn't seem to submit or send a message. Attached is the code please any help will be great. Also, the PHP and javascript have been attached for reference.
Also sometimes the page doesn't respond to the button.
If anyone can fix the code will be great.

First of all you can try check your url.Is it correct or no.For example send anything via ajax and show the response at console log.If it is not working thats mean your url is wrong.

Send Form data in Email using PHP without refreshing the page

I have a contact section in my website. I want when a user submit the form all the data should be sent in email plus the page don't reload.
My form:
<label for="name">Name:</label>
<input type="text" class="form-control" name="name" id="name" >
</div>
<div class="form-group">
<label for="email">E-Mail:</label>
<input type="email" class="form-control" name="email" id="email" >
</div>
<div class="form-group">
<label for="mobile">Mobile Number:</label>
<input type="text" class="form-control" name="mobile" id="mobile">
</div>
<div class="form-group">
<label for="message">Message:</label>
<textarea class="form-control" rows="5" name="message" id="message"></textarea>
</div>
<button type="submit" id="send" class="btn btn-primary" style="width: 100%" name="form_submit">Send Message</button>
Javascript
$(document).ready(function(){
$('#send').click(function(){
var name = $('#name').val();
var email = $('#email').val();
var mobile = $('#mobile').val();
var message = $('#message').val();
var varData = 'name=' + name + '&email=' + email + '&mobile=' + mobile + '&message=' + message;
$.ajax({
type: 'POST',
url: 'process.php',
data: varData,
success: function() {
alert("message sent");
}
});
});
});
</script>
Process.php
if (isset( $_POST['form_submit'] ) ) {
// Do processing here.
$name = $_POST['name'];
$email = $_POST['email'];
$mobile = $_POST['mobile'];
$message = $_POST['message'];
if ($name == '' || $email == '' || $mobile=='' || $message=='')
{
echo "<script> alert('please fill the field');
</script>";
exit;
}
elseif ($_POST["email"]<>'') {
$ToEmail = 'email#gmail.com';
$EmailSubject = 'Website Contact form';
$mailheader = "From: ".$_POST["email"]."\r\n";
$mailheader .= "Reply-To: ".$_POST["email"]."\r\n";
$mailheader .= "Content-type: text/html; charset=iso-8859-1\r\n";
$MESSAGE_BODY = "Name: ".$_POST["name"]."<br><br>";
$MESSAGE_BODY .= "email: ".$_POST["email"]."<br>";
$MESSAGE_BODY .= "mobile: ".nl2br($_POST["mobile"])."<br>";
$MESSAGE_BODY .= "message: ".nl2br($_POST["message"])."";
mail($ToEmail, $EmailSubject, $MESSAGE_BODY, $mailheader) or die ("Failure");
echo "<script> alert('mail sent')
</script>";
exit;
} else{
echo "<script> alert ('there is some problem');</script>";
};
}
?>
The problem is the form is not using the code mentioned in "process.php"
How can I ensure the form data is sent in email? I have searched the previous answers but couldn't fix this.

Contactform with different subjects Automaticly

What I have to do is when you click on assortiment -> roses.
http://binnenkijkenbij.nl/happycolors/roses.html
You see a page with roses, when you click on a rose it pops up in a lightbox.
Underneath the photo you can contact the company.
I want to add a custom subject for eacht flower. So if I click on the first Rose and click on contact us. A contact form has to show up or I go to the contactpage where the subject automaticly is filled with the name of the flower.
Does anyone know how I can fix this? I know some little php/javascript but, at this point I'm stuck.. I have on simple contactform where you can add an subject by yourself.
The HTML:
<div class="divide50"></div>
<div class="row">

php simple contact form - stop submit on page refresh

The following PHP form works without any issues other than on refresh. If a user hits the refresh button after submitting the form, it re-submits the form.
Is there a way to use PHP or Jquery to stop the form re-submitting after refreshing the page?
I know in PHP there should be a way with Session, but I am not sure how.
contact.php
<script src="http://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>

$honeypot = $_POST['email_confirm'];
$name = $_POST['name'];
$email = $_POST['email'];
$comments = $_POST['comments'];
// honeypot
if($honeypot)
exit(1);

<?php echo $error; ?>

}
?>
<!------- capitalize first letter Name input ---->
<script>
function toUpper(mystring) {
var sp = mystring.split(' ');
var wl=0;
var f ,r;
var word = new Array();
for (i = 0 ; i < sp.length ; i ++ ) {
f = sp[i].substring(0,1).toUpperCase();
r = sp[i].substring(1);
word[i] = f+r;
}
newstring = word.join(' ');
document.getElementById('name').value = newstring;
return true;
}
</script>

After the form has been submitted correctly run the following code:
header("Location :contact.php?msg=success");
This will redirect the user back to the contact form with an condition allowing for a message to be displayed.
if($_REQUEST['msg']){
echo "Contact Form Submitted Successfully!!";
}
If they hit refresh it will just bring up a successful message while displaying the contact form again.
Update:
if(mail($address, $e_subject, $msg, "From: $email\r\nReply-To: $email\r\nReturn-Path: $email\r\n"))
{
header("Location: contact.php?msg=success");
}else{
header("Location: contact.php?msg=error");
}
Then for displaying:
<?php if($_REQUEST['msg']=="success"){
echo "Success Message Here.";
}elseif($_REQUEST['msg']=="error"){
echo "Error Message Here."
}

$body = "New User Registration \n\n";
$body .= "========== \n\n";
$body .= "Ticket type: $_POST[typeTicket] \n\n";
if($_POST[typeTicket] == "TeamTicket") {
$body .= "Naam: $_POST[name] \n\n";
$body .= "Naam: $_POST[name1] \n\n";
$body .= "Naam: $_POST[name2] \n\n";
$body .= "Naam: $_POST[name3] \n\n";
$body .= "Naam: $_POST[name4] \n\n";
} else {
$body .= "Naam: $_POST[name] \n\n";
}
$body .= "Organisatie: $_POST[organisatie] \n\n";
$body .= "Functie: $_POST[functie] \n\n";
$body .= "Email: $_POST[email] \n\n";
//Send email
mail( $youremail, "New User Registration", $body, "From:" . $_POST['email'] );
}

How about trying this...
<script>
$('#typeTicket').on('change', function() {
if ($(this).val() === "TeamTicket") {
$("#extraNamen").show();
$("#extraNamen").attr("required",true);
} else {
$("#extraNamen").hide();
}
});
</script>
