Hi! My posts get ordered by date which is picked by an advanced custom field datepicker. I want to use the regular WordPress function references [the_title(), etc …] and the post related custom field’s. Right now the output of every loop is the the same:
January 2018
Post-a
Post-a
December 2017
Post-a
Post-a
I read setup_postdata() can have issues with sharing the same variables as ACF fields. I also tried to rename them, but no difference.
<?php
$posts = get_posts(array(
'post_type' => 'post',
'meta_key' => 'release_date',
'orderby' => 'meta_value_num',
'order' => 'DESC'
));
$group_posts = array();
if( $posts ) {
global $post;
foreach( $posts as $post ) {
$date = get_field('release_date', $post->ID, false);
$date = new DateTime($date);
$year = $date->format('Y');
$month = $date->format('F');
$group_posts[$year][$month][] = array($post, $date);
}
}
foreach ($group_posts as $yearKey => $years) {
foreach ($years as $monthKey => $months) {
echo '<li class="time">' . $monthKey . ' ' . $yearKey . '</li>';
foreach ($months as $postKey => $posts) {
setup_postdata($post); ?>
<li class="item clearfix">
<!-- WordPress Functions -->
<?php the_title();?>
<?php the_permalink();?>
<!-- Advanced Custom Fields -->
<?php the_field('blabla')?>
</li>
<?php
}
}
} wp_reset_postdata();
?>
You cannot use the function the_title() and the_permalink(), or any other WP functions that start with “the_” in the loop your using. These only work inside a standard WP post loop while (have_posts())...
You need to use alternates like https://developer.wordpress.org/reference/functions/get_the_title/ and https://developer.wordpress.org/reference/functions/get_permalink/ that allow you to specify the post ID.
