我正在尝试根据其描述对自定义帖子类别进行排序。我在下面试过了args 但它不起作用

$taxonomies = array(
    \'post_tag\',
    \'product-type\',
);

// Add the slugs of product types that should appear on the page
$slugs = array(
    \'hand-tools\',
    \'mechanical-tools\',
    \'abrasive-wheel\',
    \'garden-tools\',
    \'screens\',
    \'locks\'
);

$args = array(
    \'orderby\'           => \'description\',
    \'order\'             => \'DESC\',
    \'hide_empty\'        => false,
    \'exclude\'           => array(),
    \'exclude_tree\'      => array(),
    \'include\'           => array(),
    \'number\'            => $number,
    \'fields\'            => \'all\',
    \'slug\'              => $slugs,
    \'parent\'            => 0,
    \'hierarchical\'      => true,
    \'childless\'         => false,
    \'get\'               => \'\',
    \'name__like\'        => \'\',
    \'description__like\' => \'\',
    \'pad_counts\'        => false,
    \'offset\'            => $offset,
    \'search\'            => \'\',
    \'cache_domain\'      => \'core\'
);
