Hi,
I’m building a filter function and I’m looking for a way to echo the field values for a post type.
I have an archive page with a custom loop that gives me all posts. All these posts have a select field called “year” where you choose which year with radiobuttons.
Now to filter through them I would like to get all those years from the posts but only once.
The way I’ve done it now is to create a custom query for just getting the years but it of course returns the year for every post. I just want one of each year used in this post type (2019, 2020, 2021 and so forth).
This is my code right now:
<?php
$args = array (
'post_type' => 'match',
'post_status' => 'publish',
'posts_per_page' => -1,
);
$loop = new WP_Query($args);
if ( $loop->have_posts() ) { ?>
<?php while ( $loop->have_posts() ) { $loop->the_post(); ?>
<?php $field = get_field_object('year');?>
<?php echo $field['value']; ?></p>
<?php } ?>
<?php } ?>
<?php wp_reset_postdata(); ?>
