excellent!
Here is another expression, which is more general.
It selects at random one item from a list of items supplied,
by default from a CSV list, but the item separator can be choosen.
Combine this with (plist) or (pagelist) markuop expression and you
can construct random links like in the (rndpage) expression.
(plist0 lets you use nice exclusive and inclusive wildcard pagename
patterns.
Or you can use it for entirely different things, where you wish to
have arandom pick of something.
Again this expression function keeps track of items already choosen
before, so it will not display doubles.
//add markup expression {(random item1,item2,item3,item4 sep=SEPARATOR)}
$MarkupExpr['random'] = 'MXRandomItem($pagename, $args[0],$argp)';
function MXRandomItem($pagename, $list, $args) {
global $RandomItemsUsed; echo $args['sep'];
$sep = (isset($args['sep'])) ? $args['sep'] : ',';
$sep = str_replace('\n',"\n",$sep);
$list = explode($sep,$list);
foreach($list as $i => $item)
if (in_array($item,(array)$RandomItemsUsed) || $item=='')
unset($list[$i]);
echo "<pre>\$list "; print_r($list); echo "</pre>";
sort($list);
$i = rand(0,count($list)-1);
$RandomItemsUsed[] = $list[$i];
return $list[$i];
}
a link markup may look something like this:
[[{(random (plist -Recent* -Group*))}|+]]
