Why don't you just use the same script to display and process the form? Just set the form action attribute to an empty string and you do not even have to figure what is the current page URL. I always do that precisely for the reasons you mentioned of the form having invalided fields that need to be corrected by the user. I also use this popular class for forms generation and validation. I just specify which kinds of validation I want and the class validates the form for me on the server side. It also generates automatic Javascript code to perform validation on the browser side before the user submits the form to reduce the need to access the server to perform validation. Now there is even something better. The class comes with an AJAX form submission plug-in that lets the form be validated without reloading the page. If there are invalid fields, your script can command the forms class with that plug-in to mark the fields that are invalid. If the form is completely valid, you can process the form actions and give feedback to the user browser while the form processing occurs on the server side. When all is done you can tell the class to show a success message, wait a few secons and redirect the browser to a new page. The good part is that this works well with all browsers and you do not need to know a single bit of Javascript to implement this. Take a look in particular to the test_ajax_submit.php example. http://www.phpclasses.org/formsgeneration PS. the class also comes with another plug-in to link multiple dropdown (select) inputs loading options taken from a database. http://www.phpclasses.org/browse/view/html/file/9879/name/test_linked_select_page.html -- 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
