WP按年份查询帖子

Question

我正在尝试按以下顺序获得推荐（自定义帖子类型）。

我可以使用WP_Query类轻松检索帖子，但是如上面的屏幕截图所示，正在努力创建手风琴。

Answer 1

Try using a custom select query and looping through each post with a post_type of testimonial.

然后遍历结果并将WP_Query() class date_query参数设置为自定义选择查询结果获得的年份数组。

global $wpdb;

$posts = $wpdb->posts;

//Get all unique years as "years" from posts where post type is equal to testimonials

$sql = "SELECT DISTINCT(YEAR(`post_date`)) as years FROM $posts WHERE post_type = 'testimonials' ORDER BY years DESC"; //Get all post year list by DESC


//Loop through all results and use date_query param https://codex.wordpress.org/Class_Reference/WP_Query#Date_Parameters


$result = $wpdb->get_results($sql);

foreach($result as $rs) {
    echo '<h2>'.$rs->years.'</h2>';
    $args = array(
        'post_type' => 'testimonials',
        'post_per_page'=> -1,
        'post_status' => 'publish',
        'orderby'   => 'date',
        'order' => 'DESC',
        'date_query' => array(array(
            'year'=> $rs->years,
        ),),

    );

     $loop = new WP_Query($args);

     if($loop->have_posts()) {

        while($loop->have_posts()) : $loop->the_post();

            echo '<a href="'.get_permalink().'">'.get_the_date().'</a>';
        endwhile;

     }
}

@ user3325126很棒的代码，谢谢:) 只需将'post_per_page'=> -1替换为'posts_per_page'=> -1，（缺少1个） 应该是

'posts_per_page'=> -1,
