  • true (bool): to allow all empty values to be retained (thus no point in calling this function).
  • Specify array of keys (from data) that should be retained if you want some retained and not others.
  • Specify array of literal empty value types to retain, i.e. [ 0, '0', array(), false, null ]

“To Drupal, or to ProcessWire? The million dollar choice. We decided to make an early switch to PW. And in retrospect, ProcessWire was probably the best decision we made. Thanks are due to ProcessWire and the amazing system and set of modules that are in place.” —Unni Krishnan, Founder of PigtailPundits
