On my homepage I want to feature the information of the next coming event (custom post type), this is working and it displays all the info from the event post – except the info from the Relationship field.
The below code works on the single-event.php page but within the loop on the homepage it can’t grab them – can anybody explain why?
<?php
$today = current_time('Ymd');
$args = array(
'post_type' => 'event',
'post_status' => 'publish',
'posts_per_page' => '1',
'meta_query' => array(
array(
'key' => 'date',
'compare' => '>=',
'value' => $today,
)
),
'meta_key' => 'date',
'orderby' => 'meta_value',
'order' => 'ASC',
'paged' => ( get_query_var('paged') ? get_query_var('paged') : 1 ),
);
$query = new WP_Query($args);
if ($query->have_posts()) :
while ($query->have_posts()) : $query->the_post();
?>
<tr>
<td class="gig_date2">
<?php $date = get_field('date');
$dateD = date("d", strtotime($date));
$dateM = date("M", strtotime($date));
$dateY = date("Y", strtotime($date));
?>
<?php echo $dateM; ?> <?php echo $dateD; ?> <?php echo $dateY; ?> @ <?php the_field('venue'); ?>
<div class="entry-content">
<strong>Date:</strong> <?php the_field('date'); ?>
<strong>Venue:</strong> <?php the_field('venue'); ?>
<?php
$posts = get_field('performers');
if( $posts ): ?>
<ul>
<?php foreach( $posts as $post): // variable must be called $post (IMPORTANT) ?>
<?php setup_postdata($post); ?>
<li>
<?php the_field('name'); ?>
</li>
<?php endforeach; ?>
</ul>
<?php wp_reset_postdata(); // IMPORTANT - reset the $post object so the rest of the page works correctly ?>
<?php endif; ?>
</div>
<?php endwhile; ?>
<?php endif; ?><?php wp_reset_postdata(); ?>+ LINE-UP +</h2>
I’ve boiled down your code to the important bits so that it’s easier to see why it’s not working and what to change
<?php
// start of main loop
while (have_posts()) {
// main query is being used
the_post();
$args = array(
// your query args here ...
);
$query = new WP_Query($args);
if ($query->have_posts()) {
while ($query->have_posts()) {
// sub qury is being used
// do some stuff
$query->the_post();
$posts = get_field('performers');
if( $posts ) {
// hold the current post in a temp var
// why below
$temp_var = $post;
foreach( $posts as $post) {
setup_postdata($post);
// do stuff
}
// if we do wp_restet_postdata
// it resets to the main query, not the secondary query
// wp_reset_postdata();
// do this instead
$post = $temp_var;
}
}
// do some more stuff
// this resets to the main query
wp_reset_postdata();
}
} // end main loop
?>
