[wp-hackers] Child Themes in OOP flavour

[Thomas Scholz]

Hi Filippo,

> As you know, child themes' functions.php is *always* loaded before the

> able to override parent's methods when needed.

Offer a custom action in your parent theme:

# parent

new Parent_Theme;

class Parent_Theme
{
     public function __construct()
     {
         // set up autoloader, basic config etc, then
         do_action( 'parent_theme_loaded', $autoloader, $config, $this );
     }
}


# child

add_action( 'parent_theme_loaded', 'child_theme_init', 10, 3 );

function child_theme_init( $autoloader, $config, $parent )
{
     // load your classes, set up child theme config
}
