Dynamic Form with Upload - php

Question

Straight to the point.
I have dynamic field form. Per row, I need to insert multiple file attachments.
For example i have 3 field row.
Row 1 = 3 files
Row 2 = 2 Files
Row 3 = 3 Files
When I dd($request->all()) the files (upload[]) are not group per row, it became 8, how do i group the files?
Thanks.

Answer 1

I will add new class to you input like this:
<div class="col-md-1">
<div class="form-group">
<input type="file" name="upload[]" class="uploads" multiple />
</div>
</div>
then i create function changeUploadName() and call it when you click on add new or delete row.
function changeUploadName() {
$(".uploads").each(function(index) {
$(this).attr('name', 'upload' + index + '[]');
});
}

Answer 2

I changed the name attribute to an unique name.
To capture the request at in the laravel controller, I come out with unique variable to capture the variable.
Example:
Blade View
<div class="col-md-1">
<div class="form-group">
<input type="file" name="upload_{{ $id }}[]" class="uploads" multiple />
</div>
</div>
Controller
$store->file = $request->{'upload_'.$id}
