php - 按类别或作者 wordpress 获取帖子

Question

我想获取特定类别的帖子或特定用户的帖子。看来我们只能在 wordpress 中使用 AND 条件。我知道下面的代码是错误的，但这是我需要得到的——我想要特定用户写的所有帖子或特定类别的所有帖子

$args = array(
    'posts_per_page'   => 10,
    'offset'           => $PageStart,
    'query' => array(
    'relation' => 'OR', /* <--                here */
    array(
        'author' => 18,
    ),
    array(
        'category' => 20,
        )
    ),
    'orderby'          => 'date',
    'order'            => 'DESC',
    'post_type'        => 'post',
    'post_status'      => 'publish',

);
//print_r($args);
$author_post = get_posts( $args );

请帮忙。提前致谢。

试试这段代码

$args = array(
    'posts_per_page'   => 10,
    'offset'           => $PageStart,
    'author'       => '18',
    'orderby'          => 'date',
    'order'            => 'DESC',
    'post_type'        => 'post',
    'post_status'      => 'publish',

);
$author_post = get_posts( $args );

$args = array(

    'posts_per_page'   => 10,
    'offset'           => $PageStart,
    'category'         => '20',
    'orderby'          => 'date',
    'order'            => 'DESC',
    'post_type'        => 'post',
    'post_status'      => 'publish',
);
$category_post = get_posts( $args );
$total_post = array_merge($category_post,$author_post)
