You class method need to be static
to be access without initializing the class or public
in order to access from the class itself without reference &
. And the variable $this->itemsClass
also need to be public. So the workaround is –
class Plugin
{
public $itemsClass;
function __construct()
{
add_action('wp_ajax_list_items', array(
$this,
'list_items'
));
}
public function list_items()
{
// Get class instance
self::$itemsClass = new itemsClass();
echo "success";
die();
}
public function another_function()
{
// Can't access this function
self::$itemsClass->list_items();
return false;
}
}
