Hi there, I have a reverse relationship setup with a return format of Post Objects. I have followed your instructions (thank you) and most data comes through perfectly but can’t get the_content or the_exceprt from the relationship. I have mucked about trying get_the_content but cannot get anything to appear 🙁 Am I missing something? Renee
My code:
<?php
$items = get_posts(array(
'post_type' => 'post',
'meta_key' => 'nursery',
'orderby' => 'date',
'order' => 'ASC',
'meta_query' => array(
array(
'key' => 'nursery',
'value' => '"' . get_the_ID() . '"',
'compare' => 'LIKE'
))
));
?>
<?php if( $items ): ?>
<?php foreach( $items as $item ): ?>
<div class="news">
<?php
$photo = wp_get_attachment_url( get_post_thumbnail_id($item->ID), 'news' );
$content = the_content( $item->ID ); // have tried get_the_content
?>
<a href="<?php echo get_permalink($item->ID); ?>"
<div class="nursery-news clearfix">
<img src="<?php echo $photo ?>" alt="<?php echo get_the_title( $item->ID ); ?>" width="180" /> // gets thumbnail okay
<h3 style="clear:none"><?php echo get_the_title( $item->ID ); ?></h3>
<?php echo get_the_date( $item->ID ); ?> // gets date okay
<?php $author = get_the_author( $item->ID ); ?> <?php echo $author; ?> // gets author okay
<p><?php echo $content; ?></p> // no content appearing - have tried excerpt also
</div></a>
<?php endforeach; ?>
<?php endif; ?>
Hi Renee i have the same problem, did you get this solved somehow?
Hi Kylu, am yet to solve this problem.
Hi renee, kylu –
the reason this won’t work is that the_content and get_the_content are only meant to be used within ‘The Loop’ and therefore do not accept a post id parameter.
my personal solution to this would be using WP_Query directly (rather than get_posts) to create a secondary loop, but within the context of your code above you can probably get around this through the use of setup_postdata as in the example here:
http://codex.wordpress.org/Template_Tags/get_posts#Access_all_post_data
and remember to call wp_reset_postdata after the fact.
EDIT: as an afterthought… you should be able to access all post data directly from your $items array the same way you are accessing the id. the only problem is that this bypasses all content filters so you would have to apply them manually.
something like:
$content = apply_filters( 'the_content', $item->post_content );
Hi RBmac,
Been away from the desk. Thanks for responding. Of course, not in the loop – makes total sense and now have it working. Setup_postdata was the answer.
Code for anyone looking for it:
<?php
$args = array(
'post_type' => 'post',
'posts_per_page' => 1,
'meta_query' => array(
array(
'key' => 'field', // name of custom field
'value' => '"' . get_the_ID() . '"',
'compare' => 'LIKE'
)
)
);
$lastposts = get_posts( $args );
foreach ( $lastposts as $post ) :
setup_postdata( $post ); ?>
<h2><a href="<?php the_permalink(); ?>"><?php the_title(); ?></a></h2>
<p><?php the_content(); ?>
<?php endforeach;
wp_reset_postdata(); ?>
