Multiple file upload using jquery serialization works only at the second call

I experience a strange problem:
Form ajax call with multiple files and form values works perfect, but only on the second call. First call ends up the the success: function(result) "else" condition. Second call works perfect and sends all data to the php. So I hit the submit button once and it shows up an empty error box and I hit the submit button again and everything works perfect.
How is that possible and how to solve that?
UPDATE #1: Found workaround, but not the solution. It works when I put if (result==="") { $(".form-application").submit(); } below the success function. But thats very dirty! ... and it upload all files twice! :-(
PROBLEM SOLVED David Knipe provided the solution!! Thank you so much!!
JQUERY:
$(".form-application").submit(function(e) {
e.preventDefault();
$("#btnSubmit2").text("Please wait...");
$("#btnSubmit2").attr("disabled", true);
var files = $('#files')[0].files;
var form = $(this);
var error='';
var formData = new FormData(this);
grecaptcha.ready(function() {
grecaptcha.execute('6Le4Qb0UAAAAAHUPcsmVYIk7zc4XCsiBnf6oE-fP', {action: 'create_comment'}).then(function(token) {
$('<input>').attr({
type: 'hidden',
value: token,
name: 'token'
}).appendTo('form');
for(var count = 0; count<files.length; count++)
{
var name = files[count].name;
var extension = name.split('.').pop().toLowerCase();
if(jQuery.inArray(extension, ['gif','png','jpg','jpeg']) == -1)
{
error += "Invalid " + count + " Image File"
}
else
{
formData.append("files[]", document.getElementById('files').files[count]);
}
}
if(error == '')
{
$.ajax({
url: form.attr("action"),
method: form.attr("method"),
data: formData,
processData: false,
contentType: false,
success: function(result) {
if (result == "0") {
$("#btnSubmit2").text("Thank you!");
$("#btnSubmit2").attr("disabled", true);
$(".output_message").text("");
$(':input','.form-application')
.not(':button, :submit, :reset, :hidden')
.val('')
.prop('checked', false)
.prop('selected', false);
$(".output_message").append("<div class='alert alert-success alert-dismissible fade show' role='alert'>We have received your application!</div>");
} else {
$(".output_message").text("");
$(".output_message").append("<div class='alert alert-danger alert-dismissible fade show' role='alert'>"+result+"</div>");
$("#btnSubmit2").attr("disabled", false);
$("#btnSubmit2").text("try again");
}
}
});
}
else
{
alert(error);
}
});
});
return false;
});

PHP Script /include/process-application.php
<?PHP
echo "0";
?>

OK, I think I've figured this out. $('<input>').attr(...); sets the token attribute on a new <input> element. But this is after var formData = new FormData(this);, so the token doesn't get included in formData. Then I guess you get an authentication error, and I guess it does the authentication before it even gets to the PHP part. It would just be a HTTP401 response with no body, hence "". But then, on the second attempt, the <input> has already been created with the correct token, and this ends up being used to authenticate.

Either keep onsubmit or action. Remove action from form tag, it will work

Return mysql fetch data and insert into form field value

i have a list of clients on a page, each client has an icon to click on to edit the client details.
<i class="fas fa-user-edit gray openModal" data-modal="modal2" client="'.$client['id'].'"></i>
Everything is good up to this point. click the icon the proper modal opens and it triggers the js file just fine. (I did alot of console logs to ensure). The client variable in my jquery file holds fine and i'm able to get it passed to the php file.
in the php file i'm able to pull the information into an array and i was able to just echo the $client['firstName'] and have it show in the console.
when i moved to getting that information and parse it as the Json is when i got lost. Can someone please help me take my result and load into my form fields. The code i have now may be totally off because i've been playing with different code from different searches.
form (shortened to two fields for ease of example)
<form id="form" class="editClient ajax" action="ajax/processForm.php"

<!-- last name -->
<div class="inline">

.val("")
.html("")

Issue posting form via AJAX

I have the following form which I then send upon submit via AJAX to insert to a MySQL DB through Ajax. All inputbox in form have their own Id and I get them all in my .php process file except the ones "cas" and "dat" that do not seem to go through the AJAX posting process.
The form:
<form id="form">
<div class="form-group">
<label class="lab" for="nm">id</label>
<input disabled type="text" id="id" name="id" class="form-control" placeholder="Id">
</div>
<div class="form-group">
<input type="text" class="form-control" name="cas" id="cas" value="2">
<input type="text" class="form-control" name="dat" id="dat" value="2017-11-30">
</div>
<div class="form-group">
<label class="lab" for="nm">Product</label> <?php
//// function populate ($sql, $class,$name, $id, $title, $value,$option)
echo populate ("SELECT * FROM product_family order by product_type_id ASC","form-control","nm","nm","Select Product", "product_family", "product_family");?>
</div>
<div class="form-group">
<label class="lab" for="em">Win</label>
<input type="text" id="em" name="em" class="form-control allow_decimal" placeholder="Win">
</div>
<div class="form-group">
<label class="lab" for="hp">Drop</label>
<input type="text" id="hp" name="hp" class="form-control allow_decimal" placeholder="Drop">
</div>
<div class="form-group">
<label class="lab" for="ad">Currency</label> <?php
//// function populate ($sql, $class,$name, $id, $title, $value,$option)
echo populate ("SELECT * FROM currency order by id ASC","form-control","ad","ad","Select Currency", "currency", "currency");?>
</div>
<button type="button" id="save" class="btn btn-success" onclick="saveData()">Save</button>
<button type="button" id="update" class="btn btn-warning" onclick="updateData()">Update</button>
</form>
I then have the following JavaScript code triggering the Insert upon "save data" click in order to post the different inputbox values to my .php processing file:
function saveData(){
var id = $('#id').val();
var name = $('#nm').val();
var email = $('#em').val();
var phone = $('#hp').val();
var address = $('#ad').val();
var casino = $("#cas").val()
var date = $("#dat").val();
$.post('server.php?p=add', {id:id, nm:name, em:email, hp:phone, ad:address, cas:casino, dat:date}, function(data){
viewData()
$('#id').val(' ')
$('#nm').val(' ')
$('#em').val(' ')
$('#hp').val(' ')
$('#ad').val(' ')
})
}
function viewData(){
$.get('server.php', function(data){
$('tbody').html(data)
})
}
Then I try to read my "$_post" values on the PHP side:
if($page=='add'){
try{
$id = $_POST['id'];
$nm = $_POST['nm'];
$em = $_POST['em'];
$hp = $_POST['hp'];
$ad = $_POST['ad'];
$casino_id = $_POST['cas'];
$date = $_POST['dat'];
}
I perfectly get all variables except the dat and cas posts that do no appear in the $_post list. Listing all $_Post the following way:
$myfile = fopen("LOGPOST.txt", "w") or die("Unable to open file!");
foreach ($_POST as $key => $value){
$txt= $txt."{$key} = {$value}//";
gives the following output: id = //nm = F&B Sales//em = 1000//hp = 500//ad = EUR//
What am I doing wrong?

$.post variables not passing to php getting undefined index error

This code almost works, it inserts into the db and it is giving feedback on the page to say it has updated. However I am getting undefined index between lines 5-8 in the insert_message.php and my database is filling with blank entries (except the date).
Apologies for being new to jquery and AJAX. Need some help.

var receiver1 = $('receiver').val();
var subject1 = $('subject').val();
$.post("insert_message.php", {message:message1, sender:sender1, receiver:receiver1, subject:subject1}, function(info) { $("#result").html(info);

<?php
include("connections/conn.php");
$getsubject = mysqli_escape_string($conn,$_POST["subject1"]);
$getmessage = mysqli_escape_string($conn,$_POST["message1"]);
$getsender = mysqli_escape_string($conn,$_POST["sender1"]);
$getreceiver = mysqli_escape_string($conn,$_POST["receiver1"]);
$date = date("Y-m-d");
$insertmessage = "INSERT INTO messages (id,subject,message,date,sender,receiver) VALUES (NULL,'$getsubject','$getmessage','$date','$getsender','$getreceiver')";
$insert = mysqli_query($conn, $insertmessage) ;
if($insert){
echo "Message Sent";
}else{
echo "Message did not send";
}
UPDATE
attempted alternative way but I still get the undefined index in the inser_message.php
$(document).ready(function(){
$("#submit").click( function(e) {
e.preventDefault();
$.ajax({
url: "insert_message.php",
type: "POST",
data: $("#contact_form").serialize(),
success: function(result){
$("#result").html(result);
}
});
});
});

You have several problems in both JS and PHP.
Adjust typo in input hidden where actually name="reciever" instead of name="receiver";
In your $("#submit").click() function you're trying to selecting elements with an invalid selector (e.g. $('message').val() instead of $("#message").val());
Adjust $_POST keys by removing 1 at end. If you have any doubt, print the whole array print_r($_POST);
This is not an error but a suggestion. Since you require conn.php to do your job, I would use require instead of include.

Remove the $conn and the 1's from your 'get' block and, for example:
$getsubject = mysqli_escape_string($_POST["subject"]);
$getmessage = mysqli_escape_string($_POST["message"]);
$getsender = mysqli_escape_string($_POST["sender"]);
$getreceiver = mysqli_escape_string($_POST["receiver"]);

Form with ajax: JS not executing

I've got one big problem on only 1 page of a web site: Javascript doesn't want to be executed.
I tried to copy and paste from another web site i've done where it works perfectly... but not here. Maybe you can help me to figure out why it doesn't work...
I tried many ways, no ajax seems to work here.
Here is one of them, when i try to send a mail, i got no alert but {"reponse":"Mail sent corretly!"} instead, and the mail is corretly sent.
The submit button works! The page is refreshing, so i think the js is not executed. (i'd like to have the information without refreshing the page, like a normal ajax request).
I've tried to put the script (and the link to librairies) in the head, nothing changed.
Here is my code:
<--! Some HTML -->
<form class="form-horizontal myForm" method="post" action="contact.php">
<div class="form-group col-md-6">
<input type="text" class="form-control" name="prenom" id="prenom" placeholder="First Name" pattern="[a-zA-ZÀ-ÿ._-\s]{1,30}" required>
</div>
<div class="form-group col-md-6" style="margin-left:14px">
<input type="text" class="form-control" name="nom" id="nom" placeholder="Name" pattern="[a-zA-ZÀ-ÿ._-\s]{1,30}" required>
</div>
<div class="form-group col-md-6">
<input type="email" class="form-control" name="email" id="email" placeholder="Mail" required >
</div>
<div class="form-group col-md-6" style="margin-left:14px">
<input type="text" class="form-control" name="objet" id="objet" placeholder="Object" pattern="[a-zA-ZÀ-ÿ._-\s]{1,30}" required >
</div>
<div class="form-group col-md-12">

<div class="form-group">

<div class="col-xs-6 col-sm-2">

<div class="form-group col-md-12">

</div>
<div class="the-return"> </div>
</form>
<--! Some HTML -->
<script src="js/jquery-1.11.1.min.js"></script>
<script src="js/bootstrap.min.js"></script>
<script src="js/main.js"></script> <!-- Gem jQuery -->
<script>
$(document).ready(function() {

var fname = $('#prenom').val();
var objet = $('#objet').val();
var mail = $('#email').val();

});
}
});
});
And my php file:

{
$reponse = 'Mail not sent corretly!';
echo json_encode(['reponse' => $reponse]);
echo 'An error occurred, please try again

{
if(isset($_POST["objet"]))
{

{

$message = $_POST['message'];
// Formulaire

mail($emailAdmin, $subject, $message, $headers);
echo '<div>Thanks a lot !</div>';
$reponse = 'Mail sent corretly!';
echo json_encode(['reponse' => $reponse]);
}}}}}}}}}
?>
Thanks in advance, sorry for my poor English, it's not my native language as you can see in my code.

Not sure why it did't work, but If you want sending the data using the $.ajax request, then stick to click event. Try change the code into this :
$(document).ready(function() {
// On button click
$('#my_button').on('click', function(e) {
var $this = $('.myForm');
// Getting values
var name = $('#nom').val();
var fname = $('#prenom').val();
var objet = $('#objet').val();
var mail = $('#email').val();
var msg = $('#msg').val();
// Looking for errors
if(name === '' || fname === '' || objet === '' || mail === '' || msg === '') {
alert('Les champs doivent êtres remplis');
} else {
// Sending Ajax query
$.ajax({
url: $this.attr('action'), // form's action
type: $this.attr('method'), // form's method
data: $this.serialize(), // Serializing data
success: function(html) { // php's file response
alert(html); // Print the result
}
});
}
});
});
And change button type into :
<button type="button" class="btn btn-default" id="my_button">Submit</button>
