Data send to ajax by php are undefined after ajax success call

I have some issue with showing the response alert of the form.
$(function () {
// when the form is submitted
$('#contact-form').on('submit', function (e) {
// if the validator does not prevent form submit
if (!e.isDefaultPrevented()) {
var url = "contact.php";
// POST values in the background the the script URL
$.ajax({
type: "POST",
url: url,
data: $(this).serialize(),
success: function (data)
{
// we recieve the type of the message: success x danger and apply it to the
var messageAlert = 'alert-' + data.type;
var messageText = data.message;
// let's compose Bootstrap alert box HTML
var alertBox = '<div class="alert ' + messageAlert + ' alert-dismissable"><button type="button" class="close" data-dismiss="alert" aria-hidden="true">×</button>' + messageText + '</div>';
// If we have messageAlert and messageText
if (messageAlert && messageText) {
// inject the alert to .messages div in our form
$('#contact-form').find('.messages').html(alertBox);
// empty the form
$('#contact-form')[0].reset();
// }
}
});
return false;
}
})
});
php file looks like that
try
{
if(count($_POST) == 0) throw new \Exception('Form is empty');
$emailText = "You have a new message from your contact form\n=============================\n";
foreach ($_POST as $key => $value) {
// If the field exists in the $fields array, include it in the email
if (isset($fields[$key])) {
$emailText .= "$fields[$key]: $value\n";
}
}
// All the neccessary headers for the email.
$headers = array('Content-Type: text/plain; charset="UTF-8";',
'From: ' . $from,
'Reply-To: ' . $from,
'Return-Path: ' . $from,
);
// Send email
mail($sendTo, $subject, $emailText, implode("\n", $headers));
$responseArray = array('type' => 'success', 'message' => $okMessage);
}
catch (\Exception $e)
{
$responseArray = array('type' => 'danger', 'message' => $errorMessage);
}
The thing is that if (messageAlert && messageText) is never TRUE since the variables are that time undefined. Though emails are sent successfully and console.log(data) in js file prints wanted data.
Could you please help me to solve the problem?

You send the email, you create the response Array but you don't pass it to the ajax call.
Where is the echo of the responseArray?
The best way I suggest you is to pass it as a json data:
echo json_encode($responseArray);
And then read in the javascript function
var json = $.parseJSON(data);

Differ PhpMailer in AngularJS foreach

I have problems :
My code for emailing is working, but I don't think its the right way to do so. Is it possible to use the $http service inside an AngularJS foreach loop? Will it overheat the process, if each loop is destined to PhpMailer to send one mail each time? Should I use the $q service? The code works to send a low amount of emails but will it overheat the php script if more emails are sent?
AngularJS code
$scope.submit = function(contactform) {
$scope.submitted = true;
$scope.submitButtonDisabled = true;
angular.forEach($scope.intervenants,function(data){
var x = angular.copy($scope.formData);
x.destinataire = data.email;
$http({
method : 'POST',
url : 'contact-form.php',
data : $.param(x), //param method from jQuery
headers : { 'Content-Type': 'application/x-www-form-urlencoded' } //set the headers so angular passing info as form data (not request payload)
}).success(function(data){
console.log(data);
if (data.success) { //success comes from the return json object
$scope.submitButtonDisabled = true;
$scope.resultMessage = data.message;
$scope.result='bg-success';
} else {
$scope.submitButtonDisabled = false;
$scope.resultMessage = data.message;
$scope.result='bg-danger';
}
});
});
}
PhpMail code
//check if any of the inputs are empty
if (empty($_POST['inputName']) || empty($_POST['inputEmail']) || empty($_POST['inputSubject']) || empty($_POST['inputMessage'])) {
$data = array('success' => false, 'message' => 'Please fill out the form completely.');
echo json_encode($data);
exit;
}
//create an instance of PHPMailer
$mail = new PHPMailer();
$mail->IsSMTP();
$mail->Host = "smtp.orange.fr";
$mail->From = $_POST['inputEmail'];
$mail->FromName = $_POST['inputName'];
$mail->AddAddress($_POST['destinataire']); //recipient
$mail->Subject = $_POST['inputSubject'];
$mail->Body = "Name: " . $_POST['inputName'] . "\r\n\r\nMessage: " . stripslashes($_POST['inputMessage']);
if (isset($_POST['ref'])) {
$mail->Body .= "\r\n\r\nRef: " . $_POST['ref'];
}
if(!$mail->send()) {
$data = array('success' => false, 'message' => 'Message could not be sent. Mailer Error: ' . $mail->ErrorInfo);
echo json_encode($data);
exit;
}
$data = array('success' => true, 'message' => 'Thanks! We have received your message.');
echo json_encode($data);
} else {
$data = array('success' => false, 'message' => 'Please fill out the form completely.');
echo json_encode($data);
}

I want that after email is sent successfully then this message should be displayed
$data = '{"status":"true","message":"Email Created successfully"}';
When I commented the mail sending function then it display the successful message, I want that the message should be display after sending email.

have you tried returning a value from your send_email function?
if(!$this->email->send()){
return 'success';
}else{
$this->session->set_flashdata('message', 'To complete registration, click the link in email we just send you at khadija#precisetech.com.pk');
redirect('controller/login_register','refresh');
die();
}
then in your :
if ($last_id>0) {
$res = $this->send_email($email);
if($res === 'success'){
$data = '{"status":"true","message":"Email Created successfully"}';
}
}

Email sending with AngularJS and PHP

I have created an application in AngularJS and it has an email contact form and it sends emails using PHP file in server.
Here's my Controller.js part in AngularJS:
$scope.feedbacksubmit= function (){
var name1 = document.getElementById("name").value;
var email1 = document.getElementById("email").value;
var message1 = document.getElementById("message").value;
$http({
url: "http://boost.meximas.com/mobile/email.php",
method: "POST",
data: { name: name1, email: email1, message:message1 }
}).success(function(data, status, headers, config) {
// this callback will be called asynchronously
// when the response is available
if(status == 200) {
var return_data = data;
if(return_data != 0){
$scope.hide();
//$scope.closeFeedback();
}else{
$scope.showEmailError();
}
}
}).
error(function(data, status, headers, config) {
// called asynchronously if an error occurs
// or server returns response with an error status.
console.log(status);
$scope.showAlertNetwork();
$scope.hide();
});
};
Here's my PHP Code:
<?php
$array = json_decode(file_get_contents('php://input'), true);
$name = $array['name'];
$email = $array['email'];
$message = $array['message'];
if (($name=="")||($email=="")||($message==""))
{
printf("0");
}
else{
$from="From: $name<$email>\r\nReturn-path: $email";
$subject="Message sent using your contact form";
mail("mygmail#gmail.com", $subject, $message, $from);
}
?>
The problem arises when I fill in the contact form and hit the Send button. I'm getting $scope.showEmailError();. But I get the email without problem.
And if I try to hit the button without filling the form still getting same $scope.showEmailError(); message.

Why don't you use model values from input? It looks like you try to use AngularJS but you still think with other frameworks in mind
In the following example I'm sending model to php script, if NAME is not filled then PHP returns 404 error and it's handled in AngularJS $http via .error handler. You don't have to add so much extra logic to success to deal with it

Unable to print success message using Jquery Ajax

I'm using the Jquery Ajax to post a form data and display the success message. Everything works fine, but I'm not able to display the success message. Below is the code :
Javascript
<script>
$(document).ready(function() {
$('form').submit(function(event) { //Trigger on form submit
$('#stage').empty();
var postForm = { //Fetch form data
"name": $("#name").val(),
"element_4_1": $("#element_4_1").val(),
"element_4_2": $("#element_4_2").val(),
"element_4_3": $("#element_4_3").val(),
"email": $("#email").val(),
"input4": $("#input4").val(),
};
$.ajax({ //Process the form using $.ajax()
type : 'POST', //Method type
url : 'contact.php', //Your form processing file url
data : postForm, //Forms name
dataType : 'json',
success : function(data) {
console.log("inside success3") ;
alert(data);
$("#stage").html(data);
if (!data.success) { //If fails
if (data.errors) { //Returned if any error from process.php
$('.throw_error').fadeIn(1000).html(data.errors); //Throw relevant error
console.log("inside failure") ;
}
} else {
console.log("inside success") ;
$('#stage').fadeIn(1000).append('<p>' + data.posted + '</p>');
console.log("inside success2") ;
}
}
});
event.preventDefault(); //Prevent the default submit
});
});
</script>
PHP :
<?php
ini_set('display_errors','On');
error_reporting(E_ALL);
$errors = array();
$form_data = array();
header('Content-type: application/json');
echo json_encode($form_data);
$name=$_POST['name'];
$phone=chop($_POST['element_4_1']);
$phone.=chop($_POST['element_4_2']);
$phone.=chop($_POST['element_4_3']);
$email=chop($_POST['email']);
$message1=chop($_POST['input4']);
if ($name && $phone && $email) {
$headers = "MIME-Version: 1.0\r\n";
$headers .= "Content-type: text/plain; charset=iso-8859-1\r\n";
$headers .= "From: sales#test.com \n";
$recipient= "test#test.in";
$subject="Online Enquiry ";
$message="\nName : $name\n";
$message.="\nPhone : $phone\n";
$message.="\nEmail ID : $email\n";
$message.="\nMessage : $message1\n";
//send auto-reply
$subject_reply="Thank you for contacting us";
$message_reply="Thank you for contacting us. We will get back to you shortly.";
//mail($email, $subject_reply, $message_reply, $headers);
//Send Mail
//===========
if(isset($recipient, $subject, $message, $headers)) {
error_log($message);
$form_data['status'] = 'success';
error_log($form_data['status']);
} else {
$form_data['status'] = 'error';
error_log($form_data['status']);
} ?>
HTML
<div id="stage">
</div>
How can I print the success message

You have this at the start of your php script:
echo json_encode($form_data);
where $form_data is an empty array at that time.
You should remove that and put it at the end.
