To the PHP gang: As for the discussion re jQuery and such, there's no need -- it was not used in this demo. IOW, no jQuery was harmed. I am not against jQuery, on the contrary I think it's great, but it's not always needed for client-side functionality. As I see it, there is no need for a sledgehammer to drive a thumb tack. Please realize that all controls (input, textarea, options, selections, checkboxes, radio buttons, multi-options, etc.) can be handled this fashion. This is not your father's limited server-side php, but rather a coupling of both server-side and client-side languages to provide a more desktop-application-like user experience.

RE: [PHP] Creating drop-down menus
AJAX. Your page calls a PHP 'ajax' routine that pulls the data, sends it back as a JS array, and you re-populate the second select box. Welcome to the year 2000. Using frameworks like jQuery, this is pretty trivial these days. You're not trading any security since the PHP gets whatever parameters and checks whatever $_SESSION or other authentication and only sends back whatever data is needed. You can add some caching (memcached or whatever else) to make subsequent calls lightning fast. -Original Message- From: Ramiro Barrantes [mailto:ram...@precisionbioassay.com] Sent: Monday, July 16, 2012 1:17 PM To: php-general@lists.php.net Subject: [PHP] Creating drop-down menus Hello, I am making an application using PHP/Javascript/mysql and had a question.
