Problems with Form_Validation and Upload LIbraries

Hi,

i can use “alpha_dash”, but i want to allow dot(.) and @ as well.

In case you want to validate an email address you can use the
"valid_email" rule.
Otherwise you can write your own callback-functions additionally
to the build-in validation functions.
User Guide // Callback

About your file upload question:
Check if a file was selected for uploading like this:

Code:

if($_FILES['userfile']['size'])
{
     // do upload call
}
