Question

I have a class that acts as a wrapper to Smarty but want to use it statically across my application.

My setup looks something like this:

class Template extends Smarty {

    public function __constructor() {

         parent::__constructor();
    }

    public function setSettings() {

         $this-> some smarty settings here
    }

    public static function loadTpl($tpl) {

         self::$tplFile = $tpl;

         // other logic

         self::setSettings(); // this won't get executed because it uses non static method calls.
    }
}

How can I get around this?

Answer 1

Rather than attempt to wrap it to be called all statically, create a singleton instance and call Template::getInstance() to retrieve it rather than new Smarty():

class Template extends Smarty {
  public static $instance = NULL;

  // Private constructor can't be called
  private function __construct() {
    parent::__construct();
  }

  // Instead instantiate or return the existing instance
  public static function getInstance () {
    return self::$instance ? self::$instance : new self();
  }
}


// Instantiate as:
$smarty = Template::getInstance();
