blueimp/jQuery-File-Upload SyntaxError: Unexpected token <

Question

I am integrating the jQuery-File-Upload plugin into my php/mysqli site. I am attempting to modify the code so that when the user uploads images the user's email will be added to the database. I have added an email column to the database. My problem is when the " Start Upload " button is clicked it adds the images to the folders but does not update the database with any of the info. It throws an error, " SyntaxError: Unexpected token < " I have hunted the net with no luck and have tried multiple experiments with the code and still get the same error so any suggestions would be greatly appreciated.

Here is the index.html with the mods I did to add the email:

        <div class="container">

Answer 1

Okay I figured this out and it's working great now. I wanted to share what I found just in case somebody else does a search on this same problem.

The first problem:

In the code above for the index.php:

$query->bind_param(
                'sisss',

This won't fly because I've added a string but I forgot to add another s.

This code is now changed to:

$query->bind_param(
                    'sissss', //Added an s

I can't take any credit for this solution and I owe a big thank you to https://stackoverflow.com/users/2712069/tom-mcgee who provided my solution over at Add more custom variables to mysql insert on blueimp/jquery-file-upload

The second problem: Totally self-inflicted but I digress...

In the UploadHandler.php there is a piece of code like this:

 protected function handle_form_data($file, $index) {
        // Handle form data, e.g. $_POST['description'][$index]
           }

Yours truly changed that code to this:

protected function handle_form_data($file, $index) {
$_POST['email'][$index]
               }

Once I returned this code back to the original form everything is good to go. I reckon having this function duplicated in two different files was not a proper approach.

I would like to compliment Sebastian Tschan on this jQuery File Upload. It's very excellent and very free. If you are looking for a good upload handler you can find Mr. Tschan on GitHub at https://github.com/blueimp
