FILTER_CALLBACK -- Files?

Posted on 16th Feb 2014 07:03 pm by admin

Hi All,

I'm using the php filter functions to validate my form data. For custom filters, I'm using the FILTER_CALLBACK filter but when I'm using files, this never seems to be called? It may be that the filters are not designed to be called for files but I can't find any documentation to support that. Anybody know anything about this?
