Drupal boolean radio button/check boxes select the N/A option

I'm working on a migrate class that needs to select the N/A option from the boolean check boxes/radio buttons. I have configured my fields so 1 == True and 0 == No. But I would like to select the N/A option whenever nothing is specified in the source.

The function I call in the prepareRow function looks like this:

protected function utcYesNoBoolean($value) {
  $upper = strtoupper($value);

  switch ($upper){
    case "YES":
      return 1;
      break;

    case "NO":
      return 0;
      break;

    //Not filled in so set to NA
    default:
      return NULL;
      break;
  }
}

So if the source looks like this:

source example

  • id 1: result => 1 => select Yes
  • id 2: result => 0 => select No
  • id 3: result => NULL? => select N/A

Should I just do it like this and return a NULL and ignore the fact that the field is not selected in the UI, or is there a way to select the N/A option? What value should I be returning in order to select the N/A option? I tried with returning -1, NULL and "N/A" but no success.

Or is there maybe an option to set the default value of the field to N/Ausing the migrate field mapping?

Note: This on Drupal 7 using Commerce Kickstart if that matters. Please also note it is required to set the with PHP code in the migrate class.

Solution

  • In the meantime I figured it out myself. When you update the field on a product from No to N/A. Save it and edit it again you will see that there is nothing selected anymore.

    So in the database this will also result in an empty/deleted field/record. So there is no need to set it to anything else as Yes or No. The N/A button is there to remove the value in case you don't want the value to be there anymore.

    Thanks everyone who read the question, I could have figured this out earlier if checked the Drupal database earlier. I hope this answer is useful for some one else in the future.
