Add a new logical operator: NOT

Thanks for your idea, I have already merged the idea of logical operators (OR and AND) for inline conditions. So I think I can add a new logical operator such as NOT to cover your needs. Let me move this feature request to the correct place.

Here is my first attempt to add this new logical operator to inline conditions.

I've tested in many different configuration and it seems to work fine to me.

Reopening issue, as it's not too old yet.

This way of adding NOT doesn't really work, because NOT applies to a single condition. Right now:

• If you have only one condition, you cannot negate it;
• the 'Not' operator is equal to 'And Not' - you cannot do 'Or' with a negated condition.

The attached patch implements NOT as a separate control (checkbox) for each condition.

Remarks:

• I rewrote some code a bit; $temp is now a full condition object instead of an array. (And maybe changing '$temp = NULL' to use 'unset($temp)' was unnecessary... It just spoke more to me in this kind of situation.)
• I don't see which CSS properties to add, to be consistent with what you have already, and keep the 'negate' checkbox on the same line. Now it's wrapping (sometimes). So that's still Needs Work. For the rest: I think the code is good / tested.

Hello Roderik,

Thanks for re-opening this issue, your approach is better than mine, I've just added a CSS rule and i've fixed up the default value of the "negate" form item.

    $element[$delta]['condition_negate'] = array(
      '#type' => 'checkbox',
      '#title' => t('Negate'),
      '#default_value' => !empty($item['condition_negate']) ? $item['condition_negate'] : FALSE,
      '#prefix' => '<div class="negate-condition">',
      '#suffix' => '</div>',
    );
