Symfony2 File Upload Error – “guessExtension() always return nil”

Symfony 2.0 RC1 was released a few days ago, do not forget to grab it, it is very stable now!

Today I’m facing an error which made me crazy a few hours.

I’m trying to get the file upload on Symfony 2 done but never success on my Windows + wamp machine.

Yup, like what I’ve written on the subject, when I try to move the file using UploadedFile->move() and tell the framework to guess the file extension for me using UploadedFile->guessExtension().

It always return nil, the getExtension() is working but not useful at all because the uploaded file always be ended with tmp extension.

Even though I can’t found the solution after researched on Google for a few hours.

Until I try to dig into the symfony source code itself and I finally found it is using php_fileinfo extension!

So, I just resolve my issue by enabling the php_fileinfo extension from wamp and it works!

Wasted my few hours… Learn new things…
