Dropzone.js inside another PHP form

Question

Despite there's some documentation, there are very few real examples on how to use it.

For example: I want to include Dropzone inside my existing form that adds a product with title, description and photos.

Dropzone itself works as a form. It would be nice to use Dropzone just to preview and validate image type and size, but let the main form submit all the data. How should I do it?

This would be the idea (however, I shouldn't include a form inside a form):

<form action="products/add.php" method="POST" class="form-horizontal" role="form">
    <div class="form-group">
      <legend>Add product</legend>
    </div>

    <label for="title">Title</label>
    <input type="text" name="title" id="input-title" class="form-control">

    <label for="description">Description</label>
    <input type="text" name="description" id="input-description" class="form-control">

    <form action="/file-upload" class="dropzone" id>
      <div class="dropzone-previews"></div>
    </form>

    <div class="form-group">
      <div class="col-sm-10 col-sm-offset-2">
        <button type="submit" class="btn btn-primary">Submit</button>
      </div>
    </div>
</form>

Answer 1

Please try the following. You have to "load" dropzone programmatically as the creator explains here

 Dropzone.autoDiscover = false;
 jQuery(document).ready(function() {

   $("div#my-awesome-dropzone").dropzone({
     url: "/file/post"
   });

 });
