How to put uploaded files into collection with related user/post id?

[gsshakil]

Hi, i've added the package and copied the code from example-app. How i can submit the uploaded files into a collection when it comes with other fields in a form.
<form id="add-project"> <div class="form-group"> <label for="title">Project Title</label> <input type="text" class="form-control required" id="title" name="projectTitle" placeholder="Project Title"> </div> <div class="form-group"> <label for="upload">Upload Files</label> {{>dropzone url="/upload" id="template-helper"}} </div> <div class="form-group"> <button type="submit" class="btn btn-primary btn-block">Submit</button> </div> </form>
