获取自定义帖子类型（Wordpress）的每年帖子数量的数组

Question

我有一个名为“论文”的自定义帖子类型，为了提供图表，我需要一个包含每年有帖子的帖子数量的数组。

我尝试过使用wp_count_posts()，但它只是给了我帖子类型的总数，而get_archives() 只是静态的，我需要使用特定信息，例如每年的帖子数量。

有人知道怎么做吗？希望你能帮助我。

对于任何一直想知道同样事情的人，我从其他论坛得到它：

我创建了一个基本示例，说明如何实现此结果。

// get all posts from our CPT no matter the status
$posts = get_posts([
    'post_type'      => 'papers', // based on the post type from your qeustion
    'post_status'    => 'all',
    'posts_per_page' => -1
]);

// will contain all posts count by year
// every year will contain posts count by status (added as extra =])
$posts_per_year = [];

// start looping all our posts
foreach ($posts as $post) {
    // get the post created year
    $post_created_year = get_the_date('Y', $post);

    // check if year exists in our $posts_per_year
    // if it doesn't, add it
    if (!isset($posts_per_year[$post_created_year])) {
        // add the year, add the posts stauts with the initial amount 1 (count)
        $posts_per_year[$post_created_year] = [
            $post->post_status => 1
        ];
    // year already exists, "append" to that year the count
    } else {
        // check if stauts already exists in our year
        // if it exist, add + 1 to the count
        if (isset($posts_per_year[$post_created_year][$post->post_status])) {
            $posts_per_year[$post_created_year][$post->post_status] += 1;
        // it doesnt exist, add the post type to the year with the inital amount 1 (count)
        } else {
            $posts_per_year[$post_created_year][$post->post_status] = 1;
        }
    }
}

Answer 2

获取去年发布的帖子

$today = getdate();
$args = array(
    'post_type' => 'post',
    'posts_per_page' => -1,
    'date_query' => array(
        array(
            'year'  => $today['year'] - 1,
        ),
    ),
);
$result = new WP_Query($args);
$count = $result->found_posts;
echo $count;

其他不同的方式

$args = array(
    'type'              => 'yearly',
    'post_type'         => 'post',
    'show_post_count'   => true
);
wp_get_archives($args);

这将输出以下内容 2015 (5) 2014 (3) 2011（10）
