How to upload data-uri files in codeigniter? - codeigniter

Codeigniter's file upload library expects $_FILES[] before uploading files. If the $_FILES[] is not set, it returns an error.
I am struggling here, because I am getting the POST as JSON and that JSON contains the file as data uri.
How do I use codeigniters native file upload helper for data-uri ?

Laravel Download an Uploaded file

I need help!! I'm facing a issue with uploaded files. I don't now how to download them properly...
I have a front end that uploads files using FormData. Then, in the controller, I simply save the file (a test.txt for example) using:
request()->file('attachment')->store('logs', 'public')
It saves an rqervdrertwer.txt where it should, BUT, the content of the file is set to a base64 string.
My problem is when I try to download the file.
How could I achieve that?
If I write in my controller:
$pathToFile = storage_path('app/public/logs/' . basename($log->file));
return response()->download($pathToFile);
Then it force the browser downloading the file, exactly as it is stored; I mean, the browser gets an base64 string instead of the original content.
So, how could give a download response with a decoded file? and if it is a .pdf or other format?
Or that is not the way to save the file? maybe Laravel has a better approach instead encoding with base64?
Please, help!
Thx!
EDIT
Ok, I checked that my problem only occurs when its a .txt file. If the user uploads a .pdf, a .docx, an image, etc, it works ok. So, i'll block any .txt upload :)

ASP.NET MVC 2 - Uploaded image validation - Is there more to do than checking file extensions and MIME types?

I have a somewhat complex edit model coming into (surprise surprise) an Edit ActionMethod. One of the model's properties is a HttpPostedFileBase object, which I'd like to validate and display the validation results on the form if the file isn't legit. To this end, I've already started work on a custom ValidationAttribute object, based on RequiredAttribute (see How to validate uploaded file in ASP.NET MVC? for an idea of where I'm going).
Is there anything I can do in addition to checking the file extension and MIME type to ensure that, yes, the file being uploaded is indeed an image?
Checking the file extension or the MIME type is a start, but if you want to be sure you are dealing with a valid image you need to open the file and check its headers.
You can find more information on this in the following post:
