How to override function in parent theme via child theme function in Wordpress?

Question

I am trying to do override a function which is inside a class in the parent theme via child theme function. Can someone give me the correct way to override parent theme function via child theme function? Is it even possible on a non pluggable class?

The class itself extends from another class and the base class is pluggable.

class Fre_ReviewAction extends AE_Base --> Class attempting to overrite
----------------------------------
if (!class_exists('AE_Base')) {
class AE_Base --> Base class IS PLUGGABLE?

Answer 1

Yes you can do that , first you need to remove the action which you have used in the parent/base class.

function remove_add_class_actions() {
  //remove some action stuff , for example I used woocommerce action
  remove_action( 'some_action_hook', array( $GLOBALS['someglobals'], 'functiontooverrideinchildclass' ), 10, 3 );

  //add action by child class m in your case it will be Fre_ReviewAction
  add_action( 'some_action_hook', array(  new Fre_ReviewAction, 'functiontooverrideinchildclass' ) );
}
add_action( 'init','remove_add_class_actions' );

After that you need define the child class extending parent,

class Fre_ReviewAction extends AE_Base {
  function __construct() {
    //parent::__construct();
  }
  function functiontooverrideinchildclass(){
    //your stuff here
  }
}
