Posting additional data with Dropzone and params

I am using Dropzone and the bootstrap example to upload files. I want to also POST additional data. I have tried a number of variations after reading the answers to other questions but I can't quite get the syntax right to get the data from the input statement as I am not very experienced with javascript.

I have two fields

<input type="text" name="firstname" id="firstname">
<input type="text" name="lastname" id="lastname">

and I have tried to add params

params: {
  firstname: ?????,
  lastname: ?????,
},

I know that the method works as if I use

params: {
  firstname: "abcde",
  lastname: "vwxyz",
},

then abcde and vwxyz are posted. I just can't get the data from the input statements to POST.

The question is divided to 2.

  1. How to get the values of the inputs.
  2. How to pass params to Dropzone.

The answers:

  1. Using document.querySelector and .value (See this this answer).
  2. Since the inputs are empty when you initlize Dropzone, params should be a function that retrieve the values when you need them (e.g. click start).
params: () => ({
  firstname: document.querySelector('#firstname').value,
  lastname: document.querySelector('#lastname').value,
}),
