I want to get the file extension of one of my uploaded files in Laravel. I've tried to solve this by using the Request $request object in my controller action but it does not seem to work.
public function uploadFile (Request $request)
{
// this doesnt work for me.
$file_extension = $request->input('file_upload')->ext();
} There is a function called “extension()” on the file object in Laravel. This will return the file extension as a string. It works on every file object. E.g. on the request object or on the file facade itself. It also will work on some storage instances.
Get file extension on a uploaded file:
$extension = $request->file('file_input')->extension();Get file extension on a file saved on the filesystem:
$extension = File::get($filePath)->extension()Get the mime type on a file saved on the filesystem:
$mimeType = File::mimeType($filePath);
