AJAX, JSON, and PHP - Uncaught SyntaxError: Unexpected token < - php

Question

So I am using AJAX to upload an image with this image manager tool I am building... all of a sudden its not working... I didn't change any code or anything.
The .php runs and uploads the image, but the events I want to fire after the json is encoded and sent back arent happening. :/
The console logs Uncaught SyntaxError: Unexpected token <
The same things is happening on another AJAX request, but is fine on the third one...
In the past when I get this error, it is a PHP syntax error, but I have not updated the .php in a while.. soooo Im stumped.
Here is my Javascript:
$("#chosenfile").change(function(){
if($(this).attr('name')) {
var data;
data = new FormData();
data.append('uploadedfile', $( '#chosenfile' )[0].files[0]);
$('#loader').css('display','block');
$.ajax({
url: '/includes/uploadimage.php',
data: data,
processData: false,
contentType: false,
type: 'POST',
success: function ( data ) {
//console.log(data); //returns a string of the data.
var image = JSON.parse(data); //parses the string into an object.
console.log(image); //logs the object.
if (image.error) {
alert(image.error);
$('#remove').click();
$('#loader').css('display','none');
} else {
if (image.link) { //If the image is uploaded and returned a link.
$('#remove').click();
$('#loader').css('display','none');
$('#scrollwindow').append("<div class='you'><img imgid='" + image.id + "' src='" + image.link + "' alt=''><span class='delete'>x</span></div>").fadeIn(200);
addToSlider(1);
};
}
}
});
}
});
Here is my PHP:
<?php
include '../includes/global.php'; // General Vars and Functions I use sitewide.
/* ------------------------- */
/* -- Lets Get that file! -- */
/* ------------------------- */
$file = $_FILES["uploadedfile"];

$Return["type"] = $file["type"];
$target_path = "../uploads/"; // Define a folder to upload to
$allowedExts = array("jpeg", "jpg", "JPG", "JPEG", "image/jpg"); // Array of allowed extensions.
$extension = end(explode("/", $file["type"])); // Find extension.
$maxsize = 2097152; // Get Max file size from hidden field in form.
if ($file) {
if (in_array($extension, $allowedExts)) // If the extension is allowed.
{
if(($file["size"] < $maxsize)) { // If size is less then max file size.
$uploadResponse = "The file is a good size - ";
$target_path = $target_path . basename($file['name']); //Add file name string to upload folder destination string.
$imageLink = "http://scoutsamerica.com/uploads/" . basename( $file['name']); // This is the full link

$uploadResponse .= "This file exists: " . $target_path;
$randomNum = rand(1, 9999999);
$crudparts = explode(".", $file["name"]); //split filename and extension again.
$exceptExt = $crudparts[0]; //Filename
$extension = $crudparts[1]; //Extension
$target_path = "../uploads/" . $exceptExt . "_" . $randomNum . "." . $extension; //rename it with the random number.
$imageLink = "http://scoutsamerica.com/uploads/" . $exceptExt . "_" . $randomNum . "." . $extension;
$uploadResponse .= " Path changed to: " . $target_path;
}
if(move_uploaded_file($file['tmp_name'], $target_path)) {

$uploadResponse .= "File size: " . ($file["size"] / 1024) . "kb</br>";

}
$status = "success";
$Return["link"] = $imageLink;
/* ---------------------------------- */

/* ---------------------------------- */

}
} else {
$uploadResponse = "The file must be a .jpg file.";
$status = "failure";
$Return["error"] = $uploadResponse;
}
} else {
$uploadResponse = "No Image.";
$status = "failure";
$Return["error"] = $uploadResponse;
}
/* ------------------------- */
/* - Lets Send it back :) - */

$Return["traveler"] = $file;

Answer 1

unexpected token probably means you've got a corrupted JSON response from the server. Most likely it's an html-formatted PHP error/warning, embedded before/after the json data, e.g.
<p>PHP Warning: blah blahblah</p>[...json text here ...]
Since html is not valid json, you get that error message. So check out the RAW response from the server for that particular ajax call, and see what's coming back from the server.

Answer 2

A few things:
Why are you using \/ instead of just /?
Shouldn't the first return statement in the response be "a" not "z"?
Why do you have a block of JSON at the end of the response?
