PHP - renaming a file before uploading - php

Question

I am trying to build off a question I asked yesterday.
I am able to pass the file over to PHP using the ajax method. But I need to be able to change the file name to the booking number. For some reason, the booking was not being passed over to the PHP script. So I attempted the following:
$('#uploadBtn').on('click', function()
{
var form_data = new FormData();
form_data.append("file", document.getElementById('pdfFile').files[0]);
var booking = $('#bookingNum').val();
var partner = $('#partnerCode').val();
$.post('process/fileUpload.php', {booking:booking, partner:partner}, function(data)
{
// Wasn't sure if I needed anything here
console.log(data);
});
$.ajax({
url: 'process/fileUpload.php',
method:"POST",
data: form_data,
contentType: false,
cache: false,
processData: false,
success: function(data){console.log(data);},
error: function(jqHHR, textStatus, errorThrown){console.log('fail: ' + errorThrown);}
});
});
As you will notice above, I had to use the $.post method to send the booking and partner over to the php script.
I then used $.ajax to send the form_data over to the same script.
(I could not achieve this in one motion from yesterday's question I asked. So this is my second attempt to complete this. If there is a way to send all of the info in one motion, please refer to the question I linked above.)
So over in the PHP script, I am able to get all of the items I needed with a couple of functions:
<?php
// from the $.post method
if(isset($_POST['booking']))
{
$booking = $_POST['booking'];
$partner = $_POST['partner'];
getInfo($booking);
}
// from the $.ajax method
if($_FILES['file'])
{
$file = var_dump($_FILES['file']);
getFile($file);
}
function getInfo($booking)
{
return $booking;
}
function getFile($file)
{
return $file;
}
?>
I know it's not pretty, but I am able to get the booking (I don't need the partner right now), and I am also able to get the file information.
What I need to do is rename the file to the booking, and then finally upload it to the necessary directory.
I wasn't sure if I had to combine the functions, but I did try to no avail.
With that said, I am able to get the booking and file info within the PHP script. Now how would I go about renaming the file to the booking?

Answer 1

As you used form_data.append() to add the file data to the formdata. did it not occur to you to also use that to add the booking and partner values to it as well?
$('#uploadBtn').on('click', function()
{
var form_data = new FormData();
form_data.append("file", document.getElementById('pdfFile').files[0]);
form_data.append('booking', $('#bookingNum').val());
form_data.append('partner', $('#partnerCode').val());
$.post('process/fileUpload.php', form_data, function(data)
{
console.log(data);
});
});

To fix your ajax request (especially the illegal invocation), use the following javascript code
$('#uploadBtn').on('click', function()
{
var form_data = new FormData();
form_data.append("file", document.getElementById('pdfFile').files[0]);
form_data.append('booking', $('#bookingNum').val());
form_data.append('partner', $('#partnerCode').val());
$.ajax({
type: "POST",
url: 'process/fileUpload.php',
data: form_data,
processData: false,
contentType: false,
success: function(data) { console.log(data); }
});
});
Notice the use of processData: false and contentType: false
