yes, follow my example and understand it.
Copy the code in your editor.
I explain:
I don't use jquery, it's not important and not necessary.
If you want to pass all input , you must add class dropzone to your form.
After, you can call Dropzone.options.propertyForm=... (
propertyForm is the camelized ID of the form element)
options uploadMultiple: true and parallelUploads are important.
DropzoneJS send a XHR request(Ajax) to the url (attribute action).
It send the $_FILES and $_POST.
because it's an ajax call, don't use redirect in your PHP code, use it in your javascript.
