I got this error in Drupal after upgrading 4.6.9 to 4.7.3. Exact text (repeating several times): 

Warning: array_keys() expects parameter 1 to be array, null given in CRM_Utils_Array::formatArrayKeys() (line 1037 of /home/mysitename/public_html/sites/all/modules/civicrm/CRM/Utils/Array.php)

I was able to fix one record by editing & saving. But doing that for thousands of records wasn't an option.

So comparing custom fields of fixed records to broken records in phpMyAdmin, I found that the fixed records had blank entries whereas broken records were NULL, and that the number of fields that were checkboxes matched the number of error messages. I disabled my custom field sets and the errors went away.

After disabling my fields, I updated the custom field to set the value to blank where value is null. The SQL was similar to this: 

update `civicrm_value_custom_table_1` set `custom_field_123`="" where `custom_field_123` IS NULL;

I repeated that for all problematic fields, enabled my custom fields and all was well.

tl;dr: Cause is NULL values in custom checkbox fields. Fix is to update NULL values to blank values

  • Just a thought, but should a bug report be filed on this?

  • I considered that, but I upgraded a few more sites and didn't have the same problem. Seems like it was a fluke.

I got the same error but in my case the custom field had no value at all (no row for this id). Adding isset solves the issue, but not sure whether this is a correct way of working. Can anyone confirm?

public static function formatArrayKeys(&$array) {
++    if (isset($keys)) {
      $keys = array_keys($array, 1);
      if (count($keys) > 1 ||
        (count($keys) == 1 &&
          (current($keys) > 1 ||
            is_string(current($keys)) ||
            (current($keys) == 1 && $array[1] == 1) // handle (0 => 4), (1 => 1)
          )
        )
      ) {
        $array = $keys;
      }
    }
++  }
}
