http://snippets.dzone.com/posts Fri, 25 Jul 2008 03:48:41 GMT DZone Snippets: wrapper code http://snippets.dzone.com/posts/show/3234 This function simply calls another function based on the argument, assuming that argument ($action) is in the "allowed" list of actions. <br /> <br />settings-config.php <br /><code> <br />$settings['actions'] = "list,view,delete,update"; <br /></code> <br /> <br />Catalog-class.php <br /><code> <br />public function process_action($action) { <br /> global $settings; <br /> <br /> $allowed_actions = explode(",",$settings['actions']); <br /> if (is_numeric(array_search($action, $allowed_actions))) { <br /> $f_name = "product_" . $action; <br /> $this->$f_name(); <br /> } else { <br /> $this->error_msg = 'ACTION_NOT_ALLOWED'; <br /> } <br />} <br />private function product_list() { <br />} <br />private function product_view() { <br />} <br />private function product_delete() { <br />} <br />private function product_update() { <br />} <br />private function product_create() { <br />} <br /></code> <br /> <br />Even if product_create() exists, if you do process_action('create'), it will not work... it's basically like a function wrapper.. or something like that... <br /> <br />UPDATE: Yes I know I could have created an array like <code>$settions['actions'] = array('list','view','delete','update');</code> but I've modified this code a bit for snippet/display purposes... anyways this is just a reminder for myself, not of actual use or interest for others... comments are welcome though :D <br /> Wed, 03 Jan 2007 12:15:14 GMT http://snippets.dzone.com/posts/show/3234 alexwilliams (Alex Williams)
