Kohana 3.0 - Validate: Error if one of fields aren't empty

I have four fields. Lets call them a, b, c and d. I need to validate them.

Error is when:

Error is not when:

Any neat solution here? Thanks in advice.

Edit:

Only relationships are that all four variables are prefixed with event_. It gives me event_name, event_description etc..

Edit #2:

At the moment I have something like...

if (
       !empty($values['event_date'])
    && !empty($values['event_time'])
    && !empty($values['event_name'])
    && !empty($values['event_description'])
) {

It checks that all fields are filled up and then, if that's true, adds event.

As I said before, I need to display user-friendly error when some field isn't filled up (for example, user had forgot to enter description). Anyway, when all fields are filled up (it means - all okay) or when no fields are filled up (it means - user ignores event adding and don't want to add one) - no error should be displayed.

I could write code with 16 'if' statements, but isn't there any better way? :)

This isn't beautiful, but as long as you have something unique about the fields you want to check (such as "event_..."), you could loop through the variable array ($values, $_POST, etc) and check only the fields that matter. Then, you can easily check for an all or none situation.

Here is a quick example:

$total = 0;
$filled = 0;
foreach($values as $field => $val) {
    if(strpos($field,'event_') === 0) {
        $total++;
        if( ! empty($val)) {
            $filled++;
        }
    }
}
if($filled == 0 OR $total == $filled) {
    //PASS VALIDATION
} else {
    //FAIL VALIDATION
}

Is there a relationship between one of the entered values and the none entered values?? could you just parse it as an empty value?

if ( ! isset($post->a) )  $post->a = '';
