I'm trying to add a random order to my wordpress results with the code below. I've been told an array that calls a random number might work. Or somehow trying to include the orderby="rand" parameter somewhere.
class WC_Widget_Brand_Thumbnails_MJ extends WP_Widget {
/** Variables to setup the widget. */
var $woo_widget_cssclass;
var $woo_widget_description;
var $woo_widget_idbase;
var $woo_widget_name;
/** constructor */
function __construct() {
/* Widget variable settings. */
$this->woo_widget_name = __('WooCommerce Brand Thumbnails MJ', 'wc_brands' );
$this->woo_widget_description = __( 'Show a RANDOM Brand (Supplier) Thumbnail', 'wc_brands' );
$this->woo_widget_idbase = 'wc_brands_brand_thumbnails';
$this->woo_widget_cssclass = 'widget_brand_thumbnails';
/* Widget settings. */
$widget_ops = array( 'classname' => $this->woo_widget_cssclass, 'description' => $this->woo_widget_description );
/* Create the widget. */
$this->WP_Widget( $this->woo_widget_idbase, $this->woo_widget_name, $widget_ops );
}
/** @see WP_Widget */
function widget( $args, $instance ) {
extract( $args );
$exclude = array_map( 'intval', explode( ',', $instance['exclude'] ) );
$order = $instance['orderby'] == 'name' ? 'asc' : 'desc';
$brands = get_terms( 'product_brand', array( 'hide_empty' => $instance['hide_empty'], 'orderby' => $instance['orderby'], 'exclude' => $exclude, 'number' => $instance['number'], 'order' => $order ) );
if ( ! $brands )
return;
echo $before_widget;
if ( ! empty( $instance['title'] ) )
echo $before_title . $instance['title'] . $after_title;
woocommerce_get_template( 'widgets/brand-thumbnailsMJ.php', array(
'brands' => $brands,
'columns' => $instance['columns']
), 'woocommerce-brands', untrailingslashit( plugin_dir_path( dirname( dirname( __FILE__ ) ) ) ) . '/templates/' );
echo $after_widget;
}
/** @see WP_Widget->update */
function update( $new_instance, $old_instance ) {
$instance['title'] = strip_tags( stripslashes( $new_instance['title'] ) );
$instance['columns'] = strip_tags( stripslashes( $new_instance['columns'] ) );
$instance['orderby'] = strip_tags( stripslashes( $new_instance['orderby'] ) );
$instance['exclude'] = strip_tags( stripslashes( $new_instance['exclude'] ) );
$instance['hide_empty'] = strip_tags( stripslashes( $new_instance['hide_empty'] ) );
$instance['number'] = strip_tags( stripslashes( $new_instance['number'] ) );
if ( ! $instance['columns'] )
$instance['columns'] = 1;
if ( ! $instance['orderby'] )
$instance['orderby'] = 'name';
if ( ! $instance['exclude'] )
$instance['exclude'] = '';
if ( ! $instance['hide_empty'] )
$instance['hide_empty'] = 0;
if ( ! $instance['number'] )
$instance['number'] = '';
return $instance;
}
/** @see WP_Widget->form */
function form( $instance ) {
if ( ! isset( $instance['hide_empty'] ) )
$instance['hide_empty'] = 0;
if ( ! isset( $instance['orderby'] ) )
$instance['orderby'] = 'name';

If you just want to randomise the order of the $brands returned from the get_terms calls you could simple shuffle the results by calling shuffle($brands);
If you want to be able to choose whether the results are shuffled or not based on the orderby parameter, then you would need a little more code.
$args = array( 'hide_empty' => $instance['hide_empty'], 'orderby' => $instance['orderby'], 'exclude' => $exclude, 'number' => $instance['number'], 'order' => $order );
if ($instance['orderby'] == 'random') {
$args['orderby'] = 'none';
$brands = get_terms( 'product_brand', $args );
shuffle($brands);
}
else {
$brands = get_terms( 'product_brand', $args );
}
