Angular 'Uncaught error: Zone already loaded' - javascript

Errors in console
I am using a Mailchimp Ajax Submit jQuery Plugin to submit an email using a PHP file on a contact form in a website template I imported to my Angular app. When I go to enter my details on the form and submit, the page refreshes on the POST request.
The console then throws the following two errors.
[Deprecation] Synchronous XMLHttpRequest

I am finding it difficult to understand the cause of the problem. I have tried to prevent the page from refreshing on submit using <button type="button">, this does not do a page refresh however it does not call a POST request as expected.
I have also tried un-commenting import 'zone.js/dist/zone'; in polyfills.ts
I wish to accomplish sending the email on the same page without a refresh in the Angular app unless there is a better alternative. (I am learning)

PHP email issue with $Error message

On a Linux server, I have an ajax form that gets posted to a js script, which in turn posts to a php routine for sending a web site email contact form (Styleshout-Puremedia template). I know the post is occurring to js, and to the php page. I get an httpd server error on the php page that "$Error is undefined". However if I define it as NULL or '' it exists and therefore doesn't pass the test "if (!$Error)". If I create a hard-coded php script using the mail function, the e-mail works so php and sendmail are all configured properly. Can someone help as to why this php script doesn't work, or how to fix the "$Error" error?
PHP code:
<?php
// Replace this with your own email address
$siteOwnersEmail = 'info#mydomain.com';
if($_POST) {
$fname = trim(stripslashes($_POST['contactFname']));
$lname = trim(stripslashes($_POST['contactLname']));
$email = trim(stripslashes($_POST['contactEmail']));
$subject = trim(stripslashes($_POST['contactSubject']));
$contact_message = trim(stripslashes($_POST['contactMessage']));
// Check First Name
if (strlen($fname) < 2) {
$error['fname'] = "Please enter your first name.";
}
// Check Last Name
if (strlen($lname) < 2) {
$error['lname'] = "Please enter your last name.";
}
// Check Email
if (!preg_match('/^[a-z0-9&\'\.\-_\+]+#[a-z0-9\-]+\.([a-z0-9\-]+\.)*+[a-z]{2}/is', $email)) {
$error['email'] = "Please enter a valid email address.";
}
// Check Message
if (strlen($contact_message) < 15) {
$error['message'] = "Please enter your message. It should have at least 15 characters.";
}
// Subject
if ($subject == '') { $subject = "Contact Form Submission"; }
// Set Name
$name = $fname . " " . $lname;
// Set Message
$message = "Email from: " . $name . "<br />";
$message .= "Email address: " . $email . "<br />";
$message .= "Message: <br />";
$message .= $contact_message;
$message .= "<br /> ----- <br /> This email was sent from your site's contact form. <br />";
// Set From: header
$from = $name . " <" . $email . ">";
// Email Headers
$headers = "From: " . $from . "\r\n";
$headers .= "Reply-To: ". $email . "\r\n";
$headers .= "MIME-Version: 1.0\r\n";
$headers .= "Content-Type: text/html; charset=ISO-8859-1\r\n";
if (!$error) {
ini_set("sendmail_from", $siteOwnersEmail); // for windows server
$mail = mail($siteOwnersEmail, $subject, $message, $headers);
if ($mail) { echo "OK"; }
else { echo "Something went wrong. Please try again."; }
} # end if - no validation error
else {
$response = (isset($error['fname'])) ? $error['fname'] . "<br /> \n" : null;
$response .= (isset($error['lname'])) ? $error['lname'] . "<br /> \n" : null;
$response .= (isset($error['email'])) ? $error['email'] . "<br /> \n" : null;
$response .= (isset($error['message'])) ? $error['message'] . "<br />" : null;
echo $response;
} # end if - there was a validation error
}
?>
Thanks for your help!!
-Rob
You can always just initialize $error as
$error = [];
and then check for errors by
if(count($errors) === 0){
//no errors
}
Or, just use if(!isset($error)){//no errors}

getting a 500 error when submitting email but email still goes through

I am lost on why i am getting this internal error(500). My email info still go through when i click submit. The only problem i have is that the ajax success method is not being called so basically my callback function is never getting called on. Any help would be greatly appreciated. I have been pulling my hair out for hours on this problem.
My scipt-ajax call:
emailValidation: function(e){
e.preventDefault();
$('body, html').animate({scrollTop:0},"slow");
var valid = '';
var name = $("#f_name").val();
var email = $("#f_email").val();
var message = $("#f_message").val();
var emailReg = /^([\w-\.]+#([\w-]+\.)+[\w-]{2,4})?$/;
if(name === '' || name.length <= 2){
valid += '<p class="error">Name must be longer than 2 char.</p>';
}
if(message === '' || message.length <= 5){
valid += '<p class="error">Message must be longer than 5 char.</p>';
}
if (!(email).match(emailReg)){
valid += '<p class="error">Invalid Email</p>';
}
if (valid !== ''){
$('#form-messages').html(''+valid+'').fadeIn();
}
else {
var formData = $("#contact").serialize();//Value for sanitized form values to be paased to email.php. Value returns an array
portfolio.submitEmail(formData);
}
},
submitEmail: function(formData){
console.log(formData);
//$('#form-messages').html("Proccessing...<img src='img/processing_bar.png' alt='Proccessing' />").fadeIn('fast');
$('body, html').animate({scrollTop:0},"fast");
$.ajax({
type: 'POST',
url: 'mailer.php',
data: formData,
dataType: 'json',
success: function(result){
console.log(result.statusText);
if(result.statusText === 'OK'){
console.log('jam');
// Make sure that the formMessages div has the 'success' class.
$('#form-messages').removeClass('error');
$('#form-messages').addClass('success');
// Set the message text.
$('#form-messages').html('<p class="success">Message has been sent succesfully! Thank you '+ $('#f_name').val() +', a response will be returned in less than one business day.</p>');
$("#contact").fadeOut('slow').remove();
$('body, html').animate({scrollTop:0},"fast");
}
},
error: function(error){
console.log(error.statusText);
if(error.statusText === 'OK'){
// Make sure that the formMessages div has the 'success' class.
$('#form-messages').removeClass('error');
$('#form-messages').addClass('success');

not send when the process failed

I have PHP code that help me to other people can be in touch with me and send their opinion to me .
here's my PHP code :
<?php
$to = 'ticket.ritaweb#gmail.com';
$subject = 'Your decision/Opinion';
$name = htmlspecialchars($_REQUEST['name']);
$email = htmlspecialchars($_REQUEST['email']);
$site = htmlspecialchars($_REQUEST['site']);
$mobile = htmlspecialchars($_REQUEST['mobile']);
$nazar = htmlspecialchars($_REQUEST['nazar']);
$sqt = '2164854';
$sqtin = htmlspecialchars($_REQUEST['sqtin']);
if ($sqt === $sqtin) {
function clean_string($string) {
$bad = array("content-
type", "bcc:", "to:", "cc:", "href");
return str_replace($bad, "", $string);
}
$email_message .= "name : " . clean_string($name) . "\n";
$email_message .= "email : " . clean_string($email) . "\n";
$email_message .= "address : " . clean_string($site) . "\n";
$email_message .= "number : " . clean_string($mobile) . "\n";
$email_message .= "opinion : " . clean_string($nazar) . "\n";
$headers = 'From: ' . $mobile . "\r\n" . 'Reply-To: ' . $email . "\r\n" . 'X-Mailer:
PHP/' . phpversion();
mail($to, $subject, $email_message, $headers);
}
?>
and I called it with javascript ( ajax ) but I want a code in ajax that help me If my condition in PHP file was FALSE or each of the field was empty , show the message : "Your message was not send, be careful".
and here's my AJAX code :
<script type="text/javascript">
$(document).ready(function() {
$('#submit').click(function() {
$('#submit').attr('value', 'sending...');
$.post("themes/RitaWeb-v1/send.php", $(".rita_form").serialize(),
function(response) {
$('#submit').attr('value', 'sent.');
});
return false;
});
});
</script>
Use PHP to print messages on the page, like
{'status' : 'success'}
if the mail was sent and
{'status' : 'error'}
Then do something based on the output with js.
EDIT:
If you use jQuery.ajax instead of jQuery.post,you can also use the settings argument to let something happen if there ared errors during the request.
More information: http://api.jquery.com/jquery.ajax/
In your code, it would look like this.
PHP:
...
mail($to, $subject, $email_message, $headers);
print('{"status":"success"}');
}
else{
print('{"status":"error"}');
}
And your js:
$.ajax('themes/RitaWeb-v1/send.php').done(function(data){
status = $.parseJSON(data).status;
if(status == 'success'){
// do something
}
else if(ststus == 'error'){
// do something
}
else{
alert('unknown response');
}
});
