IS_UPLOAD_FILENAME validator

[黄祥]

hi,

i have a problem using validator IS_UPLOAD_FILENAME() to check upload
file neither avi or flv extension, is it support to check multiple
extension like on IS_IMAGE()
e.g.
IS_IMAGE(extensions = ('jpeg', 'png'))
is it support to use
IS_UPLOAD_FILENAME(extensions = ('avi', 'flv'))
thank you

IS_IMAGE(extensions = ('jpeg', 'png'))

actually checks the file type by opening it.

IS_UPLOAD_FILENAME(extension = '(avi|flv)')

only checks the extension using regex.
