    Refreshing a page to display change in data

    I have a page that scrolls out information from a database. When one
    of the records has been completed by the user, they press delete at
    the end of the row, and it sends the record id to a processing page
    that deletes that record from the database, then returns to the
    scrolling page. However, the deleted record still shows on the page
    until one presses the refresh tab on the browswer.

    Is there some way I can have the page refresh when the processing is
    done, so that the changes made will be reflected immidiatly, instead
    of the user having to press the refresh button themselves?

    Thanks,
    Bill

      Include the code on the same page?

          I don't think that'll make a difference. It's probably a problem with the
          browser's cache. Since PHP is processed server side, the browser wouldn't
          know the difference.

          Unfortunately, I don't know the answer either.

              It sounds like the user's browser is caching the page, so when it loads
              the page (presumably at the same URL) again, it just loads from the
              cache instead of getting the updated version. If you want the page not
              to cache, you can add specific headers. Here's something like what I use:

              header("Expires : Sat, 10 Jan 1970 00:00:00 GMT");
              header("Last-Modified: " . gmdate("D, d M Y H:i:s") . " GMT");
              header("Cache-Control: no-store, no-cache, must-revalidate");
              header("Cache-Control: post-check=0, pre-check=0", false);
              header("Pragma: no-cache");
              header("Content-type: text/html");

              And for good measure, in the <head> tag of your html:

              <meta http-equiv='Pragma' content='no-cache'>
              <meta http-equiv='expires' content='0'>

              These headers should make it so that the page is always considered expired
              and will be loaded fresh rather than from the cache every time the URL is
              accessed in a browser. Note that you probably shouldn't use the above
              for relatively static pages because it wastes bandwidth to have users
              reloading the same thing over and over.

                  It will automatically refresh the page.
