如何在wordpress中自定义自定义发布日期格式？

I've used custom field on my event called date. I want to display this date as: MAY 23, 2017. But it's displaying as: 20170523. I've used this code.

<?php the_field( 'date' ); ?>

Are you using Advanced Custom Fields PRO? If yes, then you can try this:

<?php
$time = strtotime( get_field( 'date' ) );
$date = date( 'F d, Y', $time );

echo $date;
?>

More native way for Advanced Custom Fields PRO would be the following:

<?php
$date = get_field( 'date', false, false );
$date = new DateTime( $date );

echo $date->format('F d, Y');
?>
