How to filter last one year custom posts by comparing acf custom field date value

Question

I have to get latest posts from only last 12 months by comparing the acf custom field datepicker value

$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

You can get the post of last a year by:

$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,
            )
      )

 );

Here we can fetch it using meta query.
