Wordpress 结果的随机顺序

问题描述 投票:0回答:1

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

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';

如果您只想随机化从

$brands
调用返回的
get_terms
的顺序,您可以通过调用
shuffle($brands);

简单地打乱结果

如果您希望能够根据

orderby
参数选择是否对结果进行打乱,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 );
}
