Validating upload form field mixed with other fields - El Forum - 10-15-2008

[eluser]jleequeen[/eluser]
Hello all,

I have a form that has a few text fields and also needs to have a field to upload a file. I am having a hard time looking at the docs and figuring out how to do this and have validation on the whole form. I would like to stay within the form validation class and not have to hack something if possible. Does the validation class and uploading class not work together?

Any ideas?

Thanks.

I'm having this issue now, the new validation class is nice, but I need to require that a file is also part of the mix. What's the cleanest way to do this?

thx!
