Input = file validation on multipart form

[eluser]Linderman[/eluser]
Hello!

I validate only 1 fields because of the example. In my life project , the form is big and the file input is required. The question is not why i validate only 1 field using the corresponding class , the question is how to validate file input using normal way?

[quote author="steelaz" date="1272150655"]I don't think you can validate file input with form_validation library, it checks $_POST array whereas uploaded file information is located in $_FILES array. You can use file upload library to check if file was uploaded or try JavaScript to validate it.[/quote]

yes this is right

[quote author="Aken" date="1272246954"]Create your own callback rule during forum validation, and use it to check the relevant file data.
