get random sub categories with get_categoreis

  • Hi,
    I have about 100 sub directories under category 3 and I would like display random 12 sub directories every time people refresh the page.

    this is what I have so far but it’s not returning anything
    My first help would be: how to retrieve all the sub categories id and store them into an array? and once that stored into an array I can then do a random function to route that array.

    $args=array(

  'child_of' => '3',
  'number' =>'12'
  );
$categories=get_categories($args);

foreach ($categories as $cat) : ?>

    thanks

  • I think this is what you want:

    $args=array(
  'child_of' => '3',
);
$categories = get_categories($args);
$number_to_show = min(12, sizeof($categories));
$picks = array_rand($categories,$number_to_show);
shuffle($picks);
foreach ($picks as $pick) {
   $cat = $categories[$pick];
   echo "<p>Category = $cat->name</p>";
}
