Okay, so if you have multiple datepicker fields on a Course, try something like this on your single-course.php to only show dates that are in the future:
$today = date( 'Y-m-d' );
if(get_field('date_1') > $today):
echo '<p>' . get_field('date_1') . '</p>';
endif;
if(get_field('date_2') > $today):
echo '<p>' . get_field('date_2') . '</p>';
endif;
etc...
Again, just make sure that the date format for $today matches what you specified in your datepicker field in the ACF settings. If that doesn’t work, you may need to do a php strtotime() with the dates.
Querying Courses by multiple ACF field dates would be a little trickery.
$today = date( 'Y-m-d' );
$args = array(
'post_type' => 'course',
'meta_query' => array(
'relation' => 'OR',
array(
'key' => 'date_1',
'value' => $today,
'compare' => '>',
),
array(
'key' => 'date_2',
'value' => $today,
'compare' => '>',
),
),
);
$query = new WP_Query( $args );
I just don’t think your can order a WP Query by multiple fields.
