for the past few days I've been trying to implement Dropzone into my form, but so far I had no luck figuring out how to make it upload and process the images only when the submit button gets clicked.
Therefore, I decided to come here and ask you guys for help.
I've made a example code structure so you can only take a look at what its necessary. Right now, I think its should work the way when I put some pictures into the Dropzone and click the button it triggers the collect_input function from the controller. But I have no clue how to process the files,etc. So, I guess what I'm asking for is a tip/solution on how to process the files from the form e.g.. Saving them to a folder and adding an entry to a database.
I'm gonna post the code below and if any of you have any tips or solutions please share them with me. I'd like to thank you all in advance for even reading this and for your replies. Btw I'm working in CodeIgniter.
