How to include the CSRF token in the headers in Dropzone upload request?

Okay so this code is working just fine now:

$("#mydropzone").dropzone({
    url: "/profile/update-photo",
    addRemoveLinks : true,
    maxFilesize: 5,
    dictDefaultMessage: '<span class="text-center"><span class="font-lg visible-xs-block visible-sm-block visible-lg-block"><span class="font-lg"><i class="fa fa-caret-right text-danger"></i> Drop files <span class="font-xs">to upload</span></span><span>&nbsp&nbsp<h4 class="display-inline"> (Or Click)</h4></span>',
    dictResponseError: 'Error uploading file!',
    headers: {
        'X-CSRF-TOKEN': $('meta[name="token"]').attr('content')
    }
});

So basically I needed to add the X-CSRFToken in the header of the Dropzone request. Works like charm now.

You can add csrf token for every jquery ajax request within your application with these code.

$.ajaxSetup({
    headers: {
        'X-CSRF-Token': $('meta[name="_token"]').attr('content')
    }
});
