AutomaticPageRefresh

Description

This recipe makes it possible for a page to refresh at set intervals, or by an interval set in a ?refresh=nn addition to a page URL.

Notes

The following will cause a browser to refresh the page every 30 seconds:

 if ($action == 'browse')@]
    $HTMLHeaderFmt['refresh'] =
       "<meta http-equiv='Refresh' Content='30; URL={\$PageUrl}' />";
 

It can be done sitewide in local/config.php (probably not recommended), or in a per-page or per-group customization file.

Or, one could use the following customization to add a '?refresh=nn' option to all pages:

 if (@$_GET['refresh']) {
   $r = $_GET['refresh'];
   $HTMLHeaderFmt['refresh'] =
     "<meta http-equiv='Refresh' Content='$r; URL={\$PageUrl}?refresh=$r' />";
 }
 

As a demonstration, this latter version is enabled at: Test.Refresh.

Release Notes

If the recipe has multiple releases, then release notes can be placed here. Note that it's often easier for people to work with "release dates" instead of "version numbers".
