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' />";
}
For demonstration, I've enabled this latter option at
http://www.pmwiki.org/wiki/Test/Refresh .
