I want to use Dropzone.js so that the user can select images he wants to upload. But I do not want them to be uploaded on the fly, rather to just be added to form and then submitted the normal way in form array. How can I do that?

I've seen questions like How to get Dropzone.js to upload files only when a submit button is clicked?, but I do not need to upload them at all, I want Dropzone to add files to my form.

BTW, dropzone is in div, not on whole form, if it is important.

Is it possible?

You need to set the autoQueue property to false when you initialize your dropzone instance:

var formData = new FormData();

//On addedfile:
Dropzone.options.myAwesomeDropzone = {
  autoQueue: false,
  init: function() {
    this.on("addedfile", function(file) { 
      formData.append("file", file); 
    });
  }
};

//On removedfile:
Dropzone.options.myAwesomeDropzone = {
  init: function() {
    this.on("removedfile", function(file) { 
      formData.delete('file');
    });
  }
};

  • Thanks. That's not what I wanted first, I wanted to add files to my form, but as I understand one cannot set value on file input due to the security reasons so your answer makes sense. So I will mark it as right. – Paul Smalling Dec 08 '16 at 11:37

    do I receive it on the server as a file input? – Cristiano Felipe Nov 23 '20 at 20:01
