When the status of an activity is changed, I need to allow the status change to go through only if certain conditions are met. If not, the status should remain the same. I was looking at the pre hook but saw this note in the pre hook documentation 'This hook does not allow the abort of the operation, use a form hook instead.' I looked for more information on this but couldn't find any. Has anyone done this kind of a thing before?
I appreciate your help.

Thanks Lobo.
I am looking at using civicrm_validate but activityid & activitytypeid are protected. When I try $form->get('_activityId') or even $form->get('_name') I am not getting any value even though I can see all the values in the debugger. How can I validate without having access to the key fields?

I get 'Call to undefined function getVar() ' & I do not see this function in Form.php. We are using civi 2.0.6 & this is the implementation for get():
    function get( $name ) {
        return $this->controller->get( $name );
    }

Is there a workaround?
Thanks.

I backported getVar & now can access all the data.
Thank you for your help.
