You will need to use AJAX/COMET requests. Regular XMLHttpRequest AJAX requests will not do because when you send the AJAX response your script exits. With AJAX/COMET requests you can send several responses to the same request without exiting the script, so you can show progress report. Take a look at these articles: http://www.phpclasses.org/blog/post/58-Responsive-AJAX-applications-with-COMET.html http://www.phpclasses.org/blog/post/51-PHPClasses-20-Beta-AJAX-XMLHttpRequest-x-IFrame.html This forms class comes with an AJAX/COMET plug-in that allows you to show progress of a task running on the server without page reloading in a single request. http://www.phpclasses.org/formsgeneration Here is is a live example script that show progress of a task running on the server after the form is submitted. http://www.meta-language.net/forms-examples.html?example=test_ajax_form -- Regards, Manuel Lemos Find and post PHP jobs http://www.phpclasses.org/jobs/ PHP Classes - Free ready to use OOP components written in PHP http://www.phpclasses.org/
