Just thinking off the top of my head, but a quick function to see if the error exists and return the error class if it does might work?

Code:

function return_error_class($err_msg)
{
if ($err_msg != null)
{
return 'error';
}
else
{
return 'normal_class';
}
}

then just call it for each input you want to check?
not sure if that' what your looking, nor if it'll work....
