I succeeded in realize what i wanted. But i don’t know if it’s safe way :
<?php function sidebar_related() {
<strong>ob_start();</strong>
$type = get_field( "themes", get_the_ID() );
$args = array(
'post_type' => 'post',
'posts_per_page' => -1,
'orderby' => 'date',
'post__not_in' => array(get_the_ID()),
'order' => 'DESC',
'meta_query' => array(
array(
'key' => 'themes',
'value' => $type
)
),
);
$my_posts = new WP_Query($args); ?>
<ul>
<?php if ( $my_posts->have_posts() ) : while ( $my_posts->have_posts() ) : $my_posts->the_post(); ?>
<li><a href="<?php the_permalink(); ?>"><?php the_title() ;?></a></li>
<?php endwhile; ?>
</ul>
<?php endif;
wp_reset_postdata();
<strong>$output_string = ob_get_contents();
ob_end_clean();
return $output_string;</strong>
}
add_shortcode('related-terms', 'sidebar_related');
Any idea ?
