No, you are not missing an option. Taxonomies are technically one-way relationships.
HOWEVER, if desired, you can retrieve the relationship info in both directions, i.e. if your relationship is Movies->Actors but you want to know which movies are tied to an actor, by using the get_objects_in_term() function:
// first, you need the actor's post id
$actor_post_id = 321;
// get_object_in_term() will return term info for all movies who are tied to this actor
$movies = $cpt_onomy->get_objects_in_term( $actor_post_id, 'movies' );
I hope this info helps.
So– if I have a list of six hundred authors– and I want the three thousand quotes to associate with them two ways… do I have to repeat that bit of code six hundred times?
Although I’m hazy on the context of what you’re doing, you should never have to repeat code 600 times. You could use a PHP loop to loop through the list of authors with your code inside the loop.
I have almost the same problem. I have two custom post : Label and Band. On single-band.php , associated labels are well recovered on the page but on the single-label.php I didn’t succeed to see the bands for this particular label.
I tried get_objects_in_term but i have empty array() in result. Any ideas ?
Are you using $cpt_onomy->get_objects_in_term()? Some CPT-onomy functions require the CPT-onomy class.
Don’t forget that you’ll probably need to add global $cpt_onomy; before you use the variable.
Yes, i have :
global $cpt_onomy;
$terms = $cpt_onomy->get_objects_in_term($post->ID, 'groupe');
if ($terms && !is_wp_error($terms)) {
foreach ($terms as $term) {
echo ("Groupe : " . $term->name);
}
}
get_objects_in_term() only returns the IDs for the objects so you have to insert another step to get term/post information.
I’m about to run out the door but you can check out my get_objects_in_term() documentation for an example.
If that didn’t help, let me know and I’ll type up another example when I get a chance.
Ok thanks for your help, i’ll check this out
Edit : It’s ok, thanks again for your help 😉
In fact another example would help me. For a given label, I can not retrieve the cpt groupe. I have all the groupe even if the label does not match.
I have :
<?php
global $cpt_onomy;
echo ("<br />Titre : " . $post->post_title . "<br />");
echo get_the_term_list($post->ID, 'origins', '<p>Origine: ', ',','</p>');
echo $post->post_content;
?>
<?php
$objects = $cpt_onomy->get_objects_in_term($post->ID,'groupe');
$args = array(
'post_type' => 'groupe',
'post__in' => $objects,
'orderby' => 'title',
'order' => 'ASC',
);
query_posts($args);
if ( have_posts() ) ?>
<ul>
<?php while ( have_posts() ) : the_post(); print_r($post);?>
<li><a href="<?php the_permalink(); ?>" title="<?php the_title(); ?>"> <?php the_title(); ?></a></li>
<?php endwhile; ?>
</ul>
Hey! Sorry for the delayed response. Been a busy week and I haven’t been able to check the forum.
The first thing that jumps out at me is the second group of code. Unless your custom post type ‘groupe’ is assigned as a CPT-onomy to itself, the post type that you use for get_objects_in_term() should be different than the post type you use for the query posts $args.
It looks as if you mean for ‘origins’ to be in get_objects_in_term(). Try this:
$objects = $cpt_onomy->get_objects_in_term( $post->ID, 'origins' );
$args = array(
'post_type' => 'groupe',
'post__in' => $objects,
'orderby' => 'title',
'order' => 'ASC',
);
query_posts( $args );
if ( have_posts() ) :
?><ul><?php
while ( have_posts() ) : the_post();
?><li><a href="<?php the_permalink(); ?>" title="<?php the_title(); ?>"><?php the_title(); ?></a></li><?php
endwhile;
?></ul><?php
endif;
Let me know if this helped… or if you already figured it out =)
Change nothing, I still have all groups and not only those belonging to a label.
This is my cpt onomies. I need to display the cpt attached to the ‘Label’ especially ‘Groupes’
my cpt
So you need to display ALL posts that are attached to a label? Just change the ‘post_type’ to ‘any’:
$objects = $cpt_onomy->get_objects_in_term( $post->ID, 'label' );
$args = array(
'post_type' => 'any',
'post__in' => $objects,
'orderby' => 'title',
'order' => 'ASC',
);
query_posts( $args );
if ( have_posts() ) :
?><ul><?php
while ( have_posts() ) : the_post();
?><li><a href="<?php the_permalink(); ?>" title="<?php the_title(); ?>"><?php the_title(); ?></a></li><?php
endwhile;
?></ul><?php
endif;
Did that do the trick?
It works great ! thanks for your help ! =)
