Ajax not refreshing contact form (PHP and Bootstrap 4)

I have this exact code on another website and it works flawlessly but for some reason on this website it won't work. It sends the email but it refreshes the page and forwards it to a contact.php with a message.
I have read through everything I could find. I have gone over the code and nothing is different. I even changed the html button type from submit to button. Nothing is working. The last thing I tried was to copy and paste the code from the working website to this site, and still it refreshes the page.
The ajax codes is being loaded after the jquery.
html (index.html):
<form id="contact-form" method="post" action="contact.php" role="form">
<div class="messages">
</div>
<div class="controls">
<div class="row">

my javascript files are in the following order:

<script src="https://cdnjs.cloudflare.com/ajax/libs/1000hz-bootstrap-validator/0.11.9/validator.min.js"></script>
<!--contact.js-->

Take out these changes:
Contact.php
// if requested by AJAX request return JSON response
if (!empty($_SERVER['HTTP_X_REQUESTED_WITH']) && strtolower($_SERVER['HTTP_X_REQUESTED_WITH']) == 'xmlhttprequest') {
$encoded = json_encode($responseArray);
header('Content-Type:application/json');
echo $encoded;
exit();
}
After echoing your json encoded array, it is important that you exit() the script else you won't end up with a proper JSON string on the client side;.
Contact.js
<script>
$(document).ready(function () {
$('.btn-send').on('click', function (e) {

Bootstrap Alert Message not working

First - Im not an expert in PHP, but just know how to make some basic changes within contact form using PHP.
On this contact form when I filled in the required textfields and hit the submit button it redirects to the contact.php with a Contact form successfully submitted.

You are echoing it (printing it) instead of returning the response, change it like this in your Contact.php
if (!empty($_SERVER['HTTP_X_REQUESTED_WITH']) &&
strtolower($_SERVER['HTTP_X_REQUESTED_WITH']) == 'xmlhttprequest') {
$encoded = json_encode($responseArray);
header('Content-Type: application/json');
return $encoded;
}
// else just display the message
else {
return $responseArray['message'];
}

Codeigniter upload image file with array field name

I'm quite new to the codeigniter library and function. Recently i had a form that had a few dynamic input field to be submit and insert into database for recording purpose.
The image upload file field was dynamically created if user click "+" button, and i was using array name as the name for the input field. However when i trying to call the controller to upload the file or insert with the array field name, it keep prompted me 'You did not select a file to upload'.
If i change the image field's input name to only 'reg_photo' and the do upload field name to 'reg_photo' then everything working fine but that is not i wanted because i wanted to upload it based on the dynamic input array.
I did try to look around the solution at stackoverflow and google but after i try and none of it could help me.
Here are my Controller to do the upload :
//Upload Picture Configuration
$config['upload_path'] = './uploads/profile_picture/';
$config['allowed_types'] = 'gif|jpg|png';
$config['max_size'] = 2048;
$config['max_width'] = 1920;
$config['max_height'] = 1080;
$this->load->library('upload', $config);
//Check and get the Areas list
$areaList = $this->input->post('areas', true);
$finalSeparator = $areaList;
$resultArea = "";
foreach ($finalSeparator as $i => $a) {
if (next($finalSeparator )) {
$resultArea .= $a.','; // Add comma for all elements instead of last
}
else
{
$resultArea .= $a;
}
}
if ($this->input->post('reg_name')) { // returns false if no property
//Get Last Inserted District ID
$district = "";
$failedUploadNameList = "";
$photoPath = "";
$data = array(
'district_code' => $this->input->post('reg_district_2', true),
'district_country' => '',
);
$this->db->set('district_registered_date', 'NOW()', FALSE); //Submit current date time
if($this->Registerlanguage_admin_model->register_district($data))
{
$district = $this->db->insert_id(); //Last Get ID
$name = $this->input->post('reg_name', true);
$year1 = $this->input->post('reg_year1', true);
$year2 = $this->input->post('reg_year2', true);
$nickname = $this->input->post('reg_nickname', true);
$photo = $this->input->post('reg_photo', true);
foreach ($name as $i => $a) { // need index to match other properties
//Check to whether can upload image or not
if ( ! $this->upload->do_upload($photo[$i]))
{
$error = array('error' => $this->upload->display_errors());
foreach($error as $q)
{
$failedUploadNameList .= $q;
}
}
else
{
$data = array('upload_data' => $this->upload->data('file_name'));
foreach($data as $a)
{
$photoPath = $config['upload_path'].$a;
}
}
$data = array(
'area_district_id' => $district,
'area_name' => $resultArea,
'area_language' => $this->input->post('reg_language', true),
'area_year_1' => isset($year1[$i]) ? $year1[$i] : '',
'area_year_2' => isset($year2[$i]) ? $year2[$i] : '',
'area_leader_name' => isset($name[$i]) ? $name[$i] : '',
'area_leader_nickname' => isset($nickname[$i]) ? $nickname[$i] : '',
'area_leader_photo' => $photoPath
);
$this->db->set('area_registered_date', 'NOW()', FALSE); //Submit current date time
if (!$this->Registerlanguage_admin_model->register_area($data)) {
// quit if insert fails - adjust accordingly
$this->session->set_flashdata('msg','<div class="alert alert-danger text-center">Oops! Error. Please try again later!!!</div>');
redirect('index.php/language_admin/index');
}
}
}
else{
// don't redirect inside the loop
$this->session->set_flashdata('msg','<div class="alert alert-danger text-center">Oops! Error. Please try again later!!!</div>');
redirect('index.php/language_admin/index');
}
//Redirect back once all successfully insert
$this->session->set_flashdata('msg','<div class="alert alert-success text-center">You are Insert Successfully!</div>'.$failedUploadNameList);
redirect('index.php/language_admin/index');
}

// don't redirect inside the loop
$this->session->set_flashdata('msg','<div class="alert alert-danger text-center">Oops! Error. Please try again later!!!</div>');

}else {
$final_files_data[] = $this->upload->data();
// Continue processing the uploaded data
}
}
}
This Worked for me. reffer to this page this is not my code
https://gist.github.com/zitoloco/1558423

Try this code to upload image
$directory = "./images/";
$config['upload_path'] = $directory;
$config['encrypt_name'] = TRUE;
$config['allowed_types'] = 'gif|jpg|png|jpeg';
if (!$this->upload->do_upload('mainimage'))
{
$error = array('error' => $this->upload->display_errors());
print_r($error);
}
else {
$data = array('upload_data' => $this->upload->data());
print_r($data);
}
And one other change is :
Replace upload.php file.
take latest verison upload.php file from system directory -> libraries directory -> upload.php. Copy new version upload.php file and replace in your project
Hope it will work properly.

If I add jQuery and change to .on("submit" of the form, it works.
$(document).ready(function() {
$("#contact-form").on("submit",function(e) {
e.preventDefault();
// Get input field values of the contact form
var user_name = $('input[name=name]').val();
var user_email = $('input[name=email-address]').val();
var user_company = $('input[name=company-name]').val();
var user_subject = $('input[name=subject]').val();
var user_message = $('textarea[name=message]').val();
// Datadata to be sent to server
post_data = {
'userName': user_name,
'userEmail': user_email,
'userCompany': user_company,
'userSubject': user_subject,
'userMessage': user_message
};
// Ajax post data to server
$.post('/php/contact-me.php', post_data, function(response) {
// Load json data from server and output message
if (response.type == 'error') {
output = '<div class="error-message"><p>' + response.text + '</p></div>';
} else {
output = '<div class="success-message"><p>' + response.text + '</p></div>';
// After, all the fields are reseted
$('#contact-form input').val('');
$('#contact-form textarea').val('');
}
$("#answer").hide().html(output).fadeIn();
}, 'json');
});
// Reset and hide all messages on .keyup()
$("#contact-form input, #contact-form textarea").keyup(function() {
$("#answer").fadeOut();
});

It seems you have a syntax error in your PHP code
$to_Email = "email#gmyemail; // Write your email here
It should change to $to_Email = "email#gmyemail"; // Write your email here
BTW, if it's not the issue, Please enable PHP debug mode and check the error logs. This may help you to find the issue.

Custom AJAX form not working async

I have a contact from that uses PHP mailer that I have integrated into my Wordpress blog. The script sends emails no problem - the issue is that it does not work async so once the form is submitted I am taken to another page with the following text on it: {"message":"Your message was successfully submitted from PHP."}. The script works as expected when used outside of wordpress - I have no idea whats going on.
PHP
<?php
/**
* Sets error header and json error message response.
*
* #param String $messsage error message of response
* #return void
*/
function errorResponse ($messsage) {
header('HTTP/1.1 500 Internal Server Error');
die(json_encode(array('message' => $messsage)));
}
/**
* Pulls posted values for all fields in $fields_req array.
* If a required field does not have a value, an error response is given.
*/
function constructMessageBody () {
$fields_req = array("name" => true, "description" => true, "email" => true, "number" => true);
$message_body = "";
foreach ($fields_req as $name => $required) {
$postedValue = $_POST[$name];
if ($required && empty($postedValue)) {
errorResponse("$name is empty.");
} else {
$message_body .= ucfirst($name) . ": " . $postedValue . "\n";
}
}
return $message_body;
}
//header('Content-type: application/json');
//attempt to send email
$messageBody = constructMessageBody();
require 'php_mailer/PHPMailerAutoload.php';
$mail = new PHPMailer;
$mail->CharSet = 'UTF-8';
$mail->setFrom($_POST['email'], $_POST['name']);
$mail->addAddress("example#example.com");
$mail->Subject = $_POST['name'];
$mail->Body = $messageBody;
//try to send the message
if($mail->send()) {
echo json_encode(array('message' => 'Your message was successfully submitted from PHP.'));
} else {
errorResponse('An expected error occured while attempting to send the email: ' . $mail->ErrorInfo);
}

change
jQuery('#form').on('submit', function(){
to
jQuery('.ajax').on('submit', function(event){
and replace ALL $ with jQuery
and
wrap your code in document ready function
jQuery(function(){});
