[support] is it possible to have validation using CCK fields?

[Larry Garfield]

No, CCK does not.

However, FAPI does. :-)  You can use hook_form_alter() in your own module 
somewhere to add another validation function to the form.  In that validation 
function, just set a form error if you don't like what the user's doing.  
FAPI will take care of rejecting the form and showing it back to the user 
with your message.  That the form is built with CCK is irrelevant to this 
task.

Cheers.

"If nature has made any one thing less susceptible than all others of 
exclusive property, it is the action of the thinking power called an idea, 
which an individual may exclusively possess as long as he keeps it to 
himself; but the moment it is divulged, it forces itself into the possession 
of every one, and the receiver cannot dispossess himself of it."  -- Thomas
