ober Posted March 16, 2006 Share Posted March 16, 2006 You can do this both ways.1) You can have them enter a part number and give them a button. The button submits the form and either takes them to a second form where they fill in additional information about the part to be submitted for insertion, or it takes them to a page that says the part already exists.2) Same as above, but you use AJAX to return the results. If you don't understand what AJAX is, check out www.ajaxfreaks.com (a sister site of phpfreaks). It's a javascript call that can run a PHP script that will return data to a specified area of your page without reloading the page.I'd personally go with AJAX, but it requires the user to have Javascript enabled to use the functionality of the site.
