how can i show only the parents in owl-carousel?
Domanda
I have this code that shows all the posts in my post type (parents and children). the php is:
<div class="owl-carousel owl-theme">
<?php
$c=0;
$q2=new WP_Query(array('post_type'=> array( 'post', 'book' ),'post_status'=> 'publish','orderby'=>'modified','order'=>'desc'));
while($q2->have_posts()) {
$c++;
$q2->the_post();
?>
<li class="item">
<a href="<?php the_permalink(); ?>">
<?php the_post_thumbnail(); ?>
<div class="metaitem">
<ul>
<li><?php the_title(); ?></li>
<li><?php the_excerpt(); ?></li>
</ul>
</div>
</a>
</li>
<?php
}
wp_reset_postdata();
?>
</div>
now what array i can use to show only the parents and don't show the children? i have used 'parent' => 0
but it didn't work!
Soluzione
According to the documentation, you would have to use post_parent => 0
So your code would look like this:
<div class="owl-carousel owl-theme">
<?php
$c = 0;
$q2 = new WP_Query( array(
'post_type' => array( 'post', 'book' ),
'post_status' => 'publish',
'post_parent' => 0, //add this here
'orderby' => 'modified',
'order' => 'desc'
) );
while ( $q2->have_posts() ) : $q2->the_post();
$c ++;
?>
<li class="item">
<a href="<?php the_permalink(); ?>">
<?php the_post_thumbnail(); ?>
<div class="metaitem">
<ul>
<li><?php the_title(); ?></li>
<li><?php the_excerpt(); ?></li>
</ul>
</div>
</a>
</li>
<?php
endwhile;
wp_reset_postdata();
?>
</div>
