Show related item by tags without using any type of plugins. Use functions code on your theme and show item by tag. So follow simple steps.
How to Do
- Open theme’s functions.php file and paste given code.
//Show Related item by tags
function single_post_related_items_by_tag() {
$current_post_id = get_the_ID();
$post_tags = get_the_tags($current_post_id);
if ($post_tags) {
$tag_ids = wp_list_pluck($post_tags, 'term_id');
$args = array(
'tag__in' => $tag_ids,
'post__not_in' => array($current_post_id),
'posts_per_page' => 4,
'orderby' => 'rand',
);
$related_query = new WP_Query($args);
if ($related_query->have_posts()) {
echo '<section class="related-posts-tag clear" nosnippet>';
echo '<h3>Related Items</h3>';
echo '<ul>';
while ($related_query->have_posts()) {
$related_query->the_post();
echo '<li><a href="' . get_the_permalink() . '">' . get_the_title() . '</a></li>';
}
echo '</ul>';
echo '</section>';
}
wp_reset_postdata(); // Reset the post data
}
}
Now SAVE functions.php file. Then open single.php file and paste given code, Where you want to show items.
<?php single_post_related_items_by_tag(); ?>
