PDF file not downloading or being saved to folder

I posted about this issue not that long ago, and I thought I had figured it out but nothing is happening.
Issue: I am trying to generate a PDF file that captures the signature of a client. Essentially they type in their name in a box and that name gets displayed in the pdf.php file along with all the other information(e.g. date, terms & conditions etc..).
I created a class that extends from FPDF and though JavaScript I am sending the name that gets filled and it gets processed through that pdf.php file and should return a "signed" pdf file.
However my pdf file is not downloading, saving or any of the options (I, D, F, S).
Below is a snippet of that section in my code.
pdf.php
$tempDir = "C:/PHP/temp/";
$thisaction = filter_input(INPUT_POST, 'action', FILTER_SANITIZE_STRING);
$answers = filter_input(INPUT_POST, 'encFormData');
$decFD = json_decode($answers);
$pdf = new WaiverFPDF();
// Pull values from array
$returnVals = array();
$returnVals['result'];
$returnVals['html'] = '';
$returnVals['errorMsg'] = '';
//the name of the person who signed the waiver
$name = $decFD->signWaiver;
$today = date('m/d/Y');
if($thisaction == 'waiverName'){
// Generate a new PDF
$pdf = new WaiverFPDF();
$pdf->AddPage()
$pdfFile = "Waiver". $name . ".pdf";
....
// Output form
$pdf->Write(8, 'I HEREBY ASSUME ALL OF THE RISKS...');
// Line Break
$pdf-> all other info...
$outFile = $tempDir . $pdfFile;
//output pdf
$pdf->Output('D', $pdfFile);
$returnVals['result'] = true;
}
else{
$returnVals['errorMsg'] = "There was an error in waiver.php";
$returnVals['result'] = false;
}
echo json_encode($returnVals);
?>
.js file (JSON)
function sendWaiver(){
var formHash = new Hash();
formHash.signWaiver = $('signWaiver').get('value');
console.log ("name being encoded");
waiverNameRequest.setOptions({
data : {
'encFormData' : JSON.encode(formHash)
}
}).send();
return true;
}
waiverNameRequest = new Request.JSON({
method : 'post',
async : false,
url : 'pdf.php',
data : {
'action' : 'waiverName',
'encFormData' : ''
},
onRequest : function() {
// $('messageDiv').set('html', 'processing...');
console.log("waiver onRequest");
},
onSuccess : function(response) {
$('messageDiv').set('html', 'PDF has been downloaded');
if (response.result == true) {
console.log('OnSuccess PDF created');
} else {
$('messageDiv').set('html', response.errorMsg);
console.log('PDF error');
}
}
});
I know my error handling is very simple, but all I am getting is success messages, but no generated pdf file... I'm not sure what i am doing wrong. I also made sure the file (when i save to a file) is writable.
class_WaiverFPDF.php
class WaiverFPDF extends FPDF
{
// Page header
function Header()
{
// Arial bold 15
$this->SetFont('Arial','B',12);
// Position XY X=20, Y=25
$this->SetXY(15,25);
// Title
$this->Cell(179,10, 'Accident Waiver ','B','C');
// Line break
$this->Ln(11);
}
// Page footer
function Footer()
{
// Position from bottom
$this->SetY(-21);
// Arial italic 8
$this->SetFont('Arial','I',8);
$this->Ln();
// Current date
$this->SetFont('Arial','I',8);
// $this->Cell(179,10,$today,0,1,'R',false);
// $today= date('m/d/Y');
$this->Cell(115,10,' Participant Name',0,0,'C');
$this->Cell(150,10,'Date',0,'C',false);
// Page number
//$this->Cell(0,10,'Page '.$this->PageNo().'/{nb}',0,0,'C');
}
}

window.location.reload(true) reloads page but page needs refreshing to show changes

Have a function that makes a change to taxonomy term via AJAX. This works great, except the content remains unchanged on window.location.reload(true) even though the change has been made. See the code and GIF below to understand.
This is an example that adds the button and reloads page on click
if ( 'publish' === $post->post_status && $post->post_type === 'campaigns' ) {
$text = (in_category( 'live') ? 'Activate' : 'Activate');
echo '<li>' . $text . '</li>';
}
So, is there another way that I can reload the page onClick that may help? Also, the post modified date is not updating, yet changes have been made to the post.
Thanks in advance for your help
EDIT -
I have already tried
location.href = location.href; and
document.location.reload();
ADDITIONAL INFO -
Function
add_action('wp_ajax_toggle_live', function(){
// Check ID is specified
if ( empty($_REQUEST['post']) ) {
die( __('No post ID specified.') );
}
// Load post
$post_id = (int) $_REQUEST['post'];
$post = get_post($post_id);
if (!$post) {
die( __('You attempted to edit an item that doesn&#8217;t exist. Perhaps it was deleted?') );
}
// Check permissions
$post_type_object = get_post_type_object($post->post_type);
if ( !current_user_can($post_type_object->cap->edit_post, $post_id) ) {
die( __('You are not allowed to edit this item.') );
}
// Load current categories
$terms = wp_get_post_terms($post_id, 'campaign_action', array('fields' => 'ids'));
// Add/remove Starred category
$live = get_term_by( 'live', 'campaign_action' );
$index = array_search($live, $terms);
if ($_REQUEST['value']) {
if ($index === false) {
$terms[] = $live;
}
} else {
if ($index !== false) {
unset($terms[$index]);
}
}
wp_set_object_terms( $post_id, 'live', 'campaign_action' );
die('1');
});
JS
function toggleLive(caller, post_id)
{
var $ = jQuery;
var $caller = $(caller);
var waitText = ". . .";
var liveText = ". . .";
var deactivateText = ". . .";
// Check there's no request in progress
if ($caller.text() == waitText) {
return false;
}
// Get the new value to set to
var value = ($caller.text() == liveText ? 1 : 0);
// Change the text to indicate waiting, without changing the width of the button
$caller.width($caller.width()).text(waitText);
// Ajax request
var data = {
action: "toggle_live",
post: post_id,
value: value
};
jQuery.post("<?php bloginfo( 'wpurl' ); ?>/wp-admin/admin-ajax.php", data, function(response)
{
if (response == "1") {
// Success
if (value) {
$caller.text(deactivateText);
} else {
$caller.text(liveText);
}
} else {
// Error
alert("Error: " + response);
// Reset the text
if (value) {
$caller.text(deactivateText);
} else {
$caller.text(liveText);
}
}
// Reset the width
$caller.width("auto");
});
// Prevent the link click happening
return false;
}
IT WORKS RIGHT ON PAGE THAT ISN'T SINGULAR

Is toggleLive the function that makes the AJAX request? You are calling reload immediately on click before changes are reflected on the backend. If you are using Jquery include your reload code in the complete callback function that indicates completion of your AJAX request.

Try using Live Query plug-in in jquery instead of live .

I was able to achieve this by setting return trueOrFalse(bool); in the JS and adding the permalink for the page into <a href=""> within the function.
I believe #cdoshi was correct in their answer, yet I was unable to achieve this. I am sure that a little further exploration would make this possible, yet my fix achieved what I wanted with little change to my code.

Form submited two times (ajax with jquery)

i have a simple form: when i submit it without javascript/jquery, it works fine, i have only one insertion in my data base, everything works fine.
I wrote some jquery to have result in ajax above the input button, red message if there was an error, green if the insertion was done successfully. I also display a small gif loader.
I don't understand why when i use this jquery, two loaders appear at the same time and two insertions are done in my database.
I reapeat that when i comment the javascript, it works fine, i'm totally sure that my php is ok.
$('#addCtg').submit(function () {
var action = $(this).attr('action');
var name = $('#name').val() ;
$('.messages').slideUp('800', function() {
$('#addCtg input[type="submit"]').hide().after('<img src="spin.gif" class="loader">');
$.post(action, {
name: name
}, function (data) {
$('.messages').html(data);
$('.messages').slideDown('slow');
$('.loader').fadeOut();
$('#addCtg input[type="submit"]').fadeIn();
});
});
return false;
});
I really don't understand why it doesn't work, because i use the 'return false' to change the basic behaviour of the submit button
Basic php just in case:
<?php
require_once('Category.class.php');
if (isset($_POST['name'])) {
$name = $_POST['name'] ;
if ($name == "") {
echo '<div class="error">You have to find a name for your category !</div>' ;
exit();
} else {
Category::addCategory($name) ;
echo '<div class="succes">Succes :) !</div>' ;
exit();
}
} else {
echo '<div class="error">An error has occur: name not set !</div>';
exit();
}
And finnaly my function in php to add in the database, basic stuff
public static function addCategory($name) {
$request = myPDO::getInstance()->prepare(<<<SQL
INSERT INTO category (idCtg, name)
VALUES (NULL, :name)
SQL
);
$r = $request->execute(array(':name' => $name));
if ($r) {
return true ;
} else {
return false ;
}
}
I rarely ask for help, but this time i'm really stuck, Thank you in advance

You're calling: $('.messages') - I bet you have 2 elements with the class messages. Then they will both post to your server.

One possible reason could be because you are using button or submit to post ajax request.
Try this,
$('#addCtg').submit(function (e) {
e.preventDefault();
var action = $(this).attr('action');
var name = $('#name').val() ;
$('.messages').slideUp('800', function() {
$('#addCtg input[type="submit"]').hide().after('<img src="spin.gif" class="loader">');
$.post(action, {
name: name
}, function (data) {
$('.messages').html(data);
$('.messages').slideDown('slow');
$('.loader').fadeOut();
$('#addCtg input[type="submit"]').fadeIn();
});
});
return false;
});

Where is the file data sent with jQueryFileUpload?

I'm working on file uploads and I wanted a plugin that could let users easily update their profile pictures, or avatars, with one click. Someone recommended jQueryFileUpload by blueimp. I have the view part of it setup (a link which, when clicked, opens a filechooser dialog), but I'm having problems receiving the file data. Fiddler shows the file data being posted to the url I want, but I can't seem to find where the data of the file I selected is being stored. Using
print_r($_POST);
shows only one parameter.
My javascript is the following:
$(".hoverAction").on('click', function(e) {
$(".fileInput:first").fileupload({
url: "/user/update",
singleFileUploads: true,
formData: {
type: "avatar"
},
add: function(e, data) {
var goUpload = true;
var uploadFile = data.files[0];
if (!(/\.(gif|jpg|jpeg|tiff|png)$/i).test(uploadFile.name)) {
common.notifyError('You must select an image file only');
goUpload = false;
}
if (uploadFile.size > 2000000) { // 2mb
common.notifyError('Please upload a smaller image, max size is 2 MB');
goUpload = false;
}
if (goUpload == true) {
data.submit();
}
}
});
$(".fileInput:first").click();
And my POST handler is the following:
function updateAction() {
$type = $_POST['type'];
switch($type) {
case "avatar":
print_r($_POST); // returns only the type param
break;
case "cover":
break;
default:
}
}

You should follow the documentation on https://github.com/blueimp/jQuery-File-Upload/wiki/Setup on how to build the back end. The plugin archives contain a basic PHP example which you can use as a starting point.

Javascript function "does not exist". Bad syntax but can't see it

The javascript is supposed to handle form submission. However, even if called with
script src="js/registerform.js"> Uncaught ReferenceError: sendreg is not defined .
The function is called onclick. Can be reproduced on www.r4ge.ro while trying to register as well as live edited. Tried jshint.com but no clue.
I will edit with any snips required.
function sendreg() {
var nameie = $("#fname").val();
var passwordie = $("#fpass").val();
var emailie = $("#fmail").val();
if (nameie == '' || passwordie == '' || emailie == '') {
alert("Please fill all the forms before submitting!");
} else {
// Returns successful data submission message when the entered information is stored in database.
$.post("http://r4ge.ro/php/register.php", {
numeleluii: nameie,
pass: passwordie,
mail: emailie
}, function(data) {
alert(data);
$('#form')[0].reset(); // To reset form fields
setTimeout(fillhome, 1000);
});
}
}
function sendpass() {
var oldpassw = $("#oldpass").val();
var newpassw = $("#newpass").val();
if (oldpassw == '' || newpassw == '') {
alert("Please fill all the forms before submitting!");
} else {
// Returns successful data submission message when the entered information is stored in database.
$.post("http://r4ge.ro/php/security.php", {
xoldpass: oldpassw,
xnewpass: newpassw
}, function(data2) {
alert(data2);
$('#passform')[0].reset(); // To reset form fields
});
}
}
function sendmail()
{
var curpass = $("#curpass").val();
var newmail = $("#newmail").val();
if (curpass == '' || newmail == '')
{
alert("Please fill all the forms before submitting!");
}
else
{
// Returns successful data submission message when the entered information is stored in database.
$.post("http://r4ge.ro/php/security.php", {
curpass: curpass,
newmail: newmail
}, function(data3) {
alert(data3);
$('#mailform')[0].reset(); // To reset form fields
});
}
}

I'm guessing here but... I imagine you are doing something like
...<button onclick="sendreg">...
And you have your <script> in the bottom on the code. Just put them on top or use $("#mybtn").click(sendreg)
Try using $("#mybtn").click(sendreg) instead of inline onclick.

The script wasn't called in the html. sorry for wasting time. A simple
<script src="js/registerform.js"></script> Fixed it.

There is no syntax error there, and I don't see any such error when trying the page.
The error that you get is that you can't make a cross domain call. Do the request to the same domain:
$.post("http://www.r4ge.ro/php/register.php", {
or:
$.post("/php/register.php", {
