WooCommerce 自定义分页未根据每页帖子选项值获取产品

Question

WooCommerce 分页不会根据每页帖子选项值获取产品。单击分页链接时显示不同的产品，有时在单击分页链接时显示正确的产品数量，但有时不显示。相同的查询适用于所有自定义分页。 这是我的代码：

public function render()
    {
        global $wp_query, $wp_rewrite;
        $args= [];
        $ordering_args =[];
        $pagination_args =[];
        $taxonomy   = 'product_cat';
      
        $args = array(
            'post_type'           => 'product',
            'post_status'         => 'publish',
            'posts_per_page'      =>  absint(get_option('posts_per_page')),
        );
      
      
        if (isset($_POST['orderby'])) {
            if ('price-desc' === $_POST['orderby']) {
                $args['orderby'] = 'price';
                $args['order']   = 'DESC';
            } elseif ('price' === $_POST['orderby']) {
                $args['orderby'] = 'price';
                $args['order']   = 'ASC';
            } elseif ('date' === $_POST['orderby']) {
                $args['orderby'] = 'date';
                $args['order']   = 'DESC';
            } else {
                $args['orderby'] = $_POST['orderby'];
                $args['order'] ='';

            }

            $ordering_args = WC()->query->get_catalog_ordering_args($args['orderby'], $args['order']);

            $args['orderby'] = $ordering_args['orderby'];
            $args['ordering_args']   = $ordering_args;
            $args['order']   = $ordering_args['order'];
            if ($ordering_args['meta_key']) {
                $args['meta_key'] = $ordering_args['meta_key'];
            }
        }

            $args['limit'] = isset($args['posts_per_page']) ? intval($args['posts_per_page']) : intval(get_option('posts_per_page'));

            if (empty($args['offset'])) {
               $args['offset'] = 1 < $args['paged'] ? ($args['paged'] - 1) * $args['limit'] : 0;

任何帮助将不胜感激。我在 ajax post 方法中使用它。

 /*Display only in stock*/
    $args['meta_query'][]= [
        'key' => '_stock_status',
        'value' => 'instock'
    ];
    /*Display only visible product*/
    $args['tax_query'][]= [
            'taxonomy'  => 'product_visibility',
            'terms'     => array( 'exclude-from-catalog' ),
            'field'     => 'name',
            'operator'  => 'NOT IN',
        ];
