Laravel 5.2/ Dropzone multiple file upload

I am attempting to add the ability to upload multiple files (in this case 3 PDF's), to my website. So far, I am able to get one file to upload and store in the DB. My DB column names are rates_1, rates_2 and rates_3. The file path is also not storing automatically in my DB, instead, the temp file path is being stored. If any one has any suggestions, I greatly appreciate it. I have been searching high and low and so far, below is the only way I am able to get it to work (for one image only).
