我正在尝试使用下面的代码向我的 wordpress 结果添加随机顺序。有人告诉我，一个调用随机数的数组可能会起作用。或者以某种方式试图在某处包含 orderby="rand" 参数。

WC_Widget_Brand_Thumbnails_MJ 类扩展 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;
}

function form( $instance ) {
    if ( ! isset( $instance['hide_empty'] ) )

如果您只想随机化调用$brands返回的顺序，get_terms您可以通过调用简单地打乱结果shuffle($brands);

如果您希望能够根据参数选择是否对结果进行混洗orderby，那么您将需要更多代码。

$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 );
}
