You may want to try this forms generation and validation class. It provides means to do exactly what you want. It comes with several plug-ins that simplify the implementation of controls like you want. There is one plug-in that can link 2 or more select inputs, on which one switches its group of options when another changes the currently selected value. The new group of options can be loaded from a static array or dynamically connecting to the server via AJAX and executing some task that gets the new set options depending on the new linked select value. It comes also with several variants of the plugin that query databases to retrieve the new sets of options. Here is a screenshot of a form using the static array version: http://www.phpclasses.org/browse/view/html/file/9879/name/test_linked_select_page.html There is also a more generic plug-in form submitting the form using AJAX. This means that you can submit the form without reloading the page. In response you can tell the class to make the current browser page be updated arbitrarily. There is now even a plug-in to integrate with Google Maps, but that is anothe story: The class and all plug-ins are available here. See the dependent classes too for more third party plug-ins: http://www.phpclasses.org/formsgeneration -- Regards, Manuel Lemos Metastorage - Data object relational mapping layer generator http://www.metastorage.net/ PHP Classes - Free ready to use OOP components written in PHP http://www.phpclasses.org/ -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
