dodotree / dropzonephpchunks Goto Github PK

First of all - thanks to everyone involved in contributing to these files. I am currently trying to customize them to fit my purposes and at the same time understand them. Below are the parts I find confusing despite pouring a lot of time into the code.

I would be super grateful if I could get some help understanding the following lines.

Loop through $FILES?:

Isn't this loop only required if we have multiple file inputs in the same form as according to PHO Uploading multiple files? I am trying to understand if there is any other need to loop through the $FILES array since Dropzone seems Dropzone seems to handle multiple files (regardless of drag and drop or clicking and selecting files) as individual requests.

$file['filename']:

Is $file['filename'] set by Dropzone or is it a custom variable used in this script? Despite extensive experiments I can't see $file['filename'] ever being populated with a value. PHP POST method uploads mentions $_FILES['userfile']['name'] but not filename so will this ever not be empty? What I am trying to get at is if there is a reason this row is not just simply $filename = $file['name'];

$tmp_file_path:

Why is $tmp_file_path updated here? The only place I can see it being used is in the function resumableUpload() which is called three lines before $tmp_file_path is updated. It seems a bit pointless to update a variable after it is already used, but this might have something to do with my first question.

I'm curious about DZUUID in chunk.php. It does not mention in official documentation. What is the function of the POST value (other POST values such as dztotalfilesize as well)? How should I implement them?

Also in chunk.js, params is not defined. Can you post your HTML as well?

Thanks for your help.
