Question

我正在尝试显示Wordpress Woothemes小部件“品牌缩略图”的分类法描述。

这里的代码返回一个随机的术语（即1个随机品牌），但我还希望它包含随机品牌描述。最好用div包裹。

/** 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';


    /**MJ added args and else function MJ*/
    $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);
    $brands = array_slice($brands, 0, 1);

    }
    else {
    $brands = get_terms( 'product_brand', $args );
    }

    /**MJ added args and else function MJ*/


    if ( ! $brands ) 
        return;

    ), 'woocommerce-brands', untrailingslashit( plugin_dir_path( dirname( dirname( __FILE__ ) ) ) ) . '/templates/' );

    echo $after_widget;

Answer 1

我修好了。因此，对于偶然发现类似问题的其他人，我使用了

<?php echo $brand->description; ?>

我还需要截断它，我在function.php中使用了这个函数

function limit_words($string, $word_limit) {
$newstring = substr($string, 0, $word_limit);
if(strlen($newstring) < strlen($string))
$newstring = $newstring."...";
echo "<p>".$newstring."</p>";
}

和此修改后的描述调用（而不是上面的描述调用）

<?php echo limit_words($brand->description,100); ?>

获取每个术语的Wordpress自定义后分类描述
