如何通过比较 acf 自定义字段日期值来过滤过去一年的自定义帖子

Question

我必须通过比较 acf 自定义字段日期选择器值来获取最近 12 个月的最新帖子

$args = array( 
  'post_type' => 'news',
  'paged' => (get_query_var('paged')) ? get_query_var('paged') : 1,
   'meta_query' => array(
array(
    'key' => 'publication_date',
     'after'   => '-365 days',
 ),
 ),
 'orderby' => 'meta_value',
  'order' => 'DESC',
  'hide_empty' => 0,
   'pad_counts' => false, 
 );

Answer 1

您可以通过以下方式获得过去一年的post：

$today = date('Ymd'); // Today's date
$date = strtotime($today.' -1 year'); // converting into string and doing minus a year
$lastyear = date('Ymd', $date); //get the date of the last year

$args = array( 
  'post_type' => 'news',
  'paged' => (get_query_var('paged')) ? get_query_var('paged') : 1,
  'orderby' => 'meta_value',
  'order' => 'DESC',
  'hide_empty' => 0,
  'pad_counts' => false,

    'meta_query' => array(
      'relation' => 'AND',
           array(
                'key'       => 'publication_date',
                'compare'   => '<=',
                'value'     => $today,
            ),
               array(
                'key'       => 'publication_date',
                'compare'   => '>=',
                'value'     => $lastyear,
            )
      )

 );

在这里我们可以使用元查询来获取它。

             );

        <?php

        the_posts_pagination(

                'before_page_number' => '<span class="meta-nav screen-reader-text">' . __( 'Page', 'theme' ) . ' </span>',
            )
        );
        ?>
