Hello,
I got a CPT called events and would like to display the name of the related artist (which I am relating with the relationship field) to the event. This is my code, in which I can’t assign the field to a variable and then include the value into the loop:
<div class="container">
<div class="row">
<table>
<tr>
<th>Artista</th>
<th>Fecha</th>
<th>Ciudad</th>
<th>Información</th>
</tr>
<?php
$artista_evento = get_field('artista_del_evento');
$today = current_time('Ymd');
$args = array(
'post_type' => 'evento',
'post_status' => 'publish',
'posts_per_page' => '-1',
'meta_query' => array(
array(
'key' => 'fecha_del_evento',
'compare' => '>=',
'value' => $today,
),
),
'meta_key' => 'fecha_del_evento',
'orderby' => 'meta_value',
'order' => 'ASC',
);
$query = new WP_Query($args);
if ($query->have_posts()) :
while ($query->have_posts()) : $query->the_post();
?>
<?php $i = 0;?>
<?php if($i == 0){ echo "<tr>"; }?>
<td><?php echo get_the_title( $artista_evento->ID ); ?></td>
<?php $i++;?>
<td><?php the_field('fecha_del_evento'); ?></td>
<?php $i++;?>
<td><?php the_field('lugar_del_evento'); ?></td>
<?php $i++;?>
<td><?php echo get_the_content(); ?></td>
<?php $i++;?>
<?php if($i == 4){ echo "</tr>"; $i=0;}?>
<?php endwhile; ?>
<?php if($i < 4) echo '</tr>'; ?>
</table>
<?php wp_reset_postdata(); ?>
<?php endif; ?>
</div><!-- END OF ROW -->
</div><!-- END OF CONTAINER -->
You need to move the get_field into the loop. You are performing this function outside the loop so the post ID is either wrong or non-existent when you call the function.
// ... code before query & loop
$args = array(
'post_type' => 'evento',
'post_status' => 'publish',
'posts_per_page' => '-1',
'meta_query' => array(
array(
'key' => 'fecha_del_evento',
'compare' => '>=',
'value' => $today,
),
),
'meta_key' => 'fecha_del_evento',
'orderby' => 'meta_value',
'order' => 'ASC',
);
$query = new WP_Query($args);
if ($query->have_posts()) :
while ($query->have_posts()) : $query->the_post();
// put your get_field call here
$artista_evento = get_field('artista_del_evento');
$today = current_time('Ymd');
// the rest of your template code ...
Hello John,
I recieve this message: Trying to get property of non-object in …/wildlion/wp-content/themes/wildlion/archive-evento.php on line 71 The Faith Keepers en dondesea
Line 71: <td><?php echo get_the_title( $artista_evento->ID ); ?></td>
What is get_field('artista_del_evento'); returning.
Is this field set to return an Object or an ID?
You can add echo $artista_evento; to test what’s being returned.
It was returning an ID, now I’ve changed it to return an object (in the Back-End) and also changed the code, previously I was receiving the following message:
Trying to get property of non-object in… (same as above).
The final code:
$query = new WP_Query($args);
if ($query->have_posts()) :
while ($query->have_posts()) : $query->the_post();
?>
<?php $i = 0;?>
<?php if($i == 0){ echo "<tr>"; }?>
<td>
<?php
$artista_evento = get_field('artista_del_evento');
foreach ($artista_evento as $av) {
echo get_the_title( $av->ID );
}
?>
</td>
<?php $i++;?>
<td><?php the_field('fecha_del_evento'); ?></td>
<?php $i++;?>
<td><?php the_field('lugar_del_evento'); ?></td>
<?php $i++;?>
<td><?php echo get_the_content(); ?></td>
<?php $i++;?>
<?php if($i == 4){ echo "</tr>"; $i=0;}?>
<?php endwhile; ?>
<?php if($i < 4) echo '</tr>'; ?>
</table>
<?php wp_reset_postdata(); ?>
Did it clear up the error? is it working?
Sorry, yes, it is working. Thank you very much for your help.
