Refresh web page when using Browser back button

fx.php

April 14, 200817 yr

Hi there,

We have an online multiple registration system which contains a summary page with a list of possible students and courses. Each course is listed under each student with a checkbox - to register students, the corresponding checkbox needs to be tagged. Courses that have been checked previously become disabled to prevent duplicate registrations. The process ends up taking the browser to a tax invoice/receipt page.

However when a browser uses their Back button to return to the summary page the most recent registration checkboxes are still active as the page has not refreshed itself (because it loads from the preceding login page). Is it possible to make a page refresh without leaving the current training account? Using does not work as when it refreshes it takes the browser to the first record in the database, eg a totally different account! Is it possible to add code that makes the refresh search for a particular username and password perhaps, or some other way of making the page reload correctly when accessed by the Back button?

All advice gratefully received.

Yes, there's a way; if your form retrieves a POST variable, even if it's bogus, it'll have to reload every time, even when someone uses the BACK button.

So one way to force your page to reload might be to make sure that you reach it through a POST command.

Hope this helps,

Bob Patin
