I have custom post type 'cars' and its child post type is 'carvariants'.
What I want to do is get child posts (carvariants) of current post (cars). I tried this code:
<div>
<?php
$parent_id = 1064;
$the_query = new WP_Query(array(
'post_parent' => $parent_id,
'post_type' => 'carvariants',
'posts_per_page' => 1,
'meta_key' => 'wpcf-minimum-price',
'orderby' => 'meta_value_num',
'order' => 'ASC'
));
?>
<?php if( $the_query->have_posts() ): ?>
<ul>
<?php while( $the_query->have_posts() ) : $the_query->the_post();
$compprd = get_the_ID(); ?>
<?php the_title(); ?>
<?php
endwhile; ?>
</ul>
<?php endif; ?>
<?php wp_reset_query(); ?>
</div>
I want to display child posts of Cars order by custom field wpcf-minimum-price but 'post_parent' is not working. This code is showing blank output. Whats wrong in this?
