    My current related posts are related by categories. I’d like to make them related by tags.

    Please help.

    So far, I’ve changed the top part like this, but got stuck:

    *Get current post's tags*/
$post_tags_temp = wp_get_post_tags( $post->ID );
$post_tags = array();
if( !empty( $post_tags_temp )){
	foreach ( $post_tags_temp as $tag) {
		$post_tags[] = $tag->term_ID;
	}
}

    Here’s link to full file:

    I used your template to create another function, which is able to fetch related posts based on categories, I think you will be able to use it in a template to achieve what you are trying to.

    Here’s the code

    function get_related_posts_by_taxonomy($args) {
    $defaults = array(
        'post_id' => get_the_ID(),
        'num_posts' => 6,
        'taxonomy' => 'category',
    );
    $args = wp_parse_args($args, $defaults);

    /* Get current post's categories */
    $post_cats_temp = get_the_category($post->ID);
    $post_cats = array();
    if (!empty($post_cats_temp)) {
        foreach ($post_cats_temp as $cat) {
            $post_cats[] = $cat->cat_ID;
        }
    }
    unset($post_cats_temp);
    if (empty($post_cats)) {
        return false;
    }
    /* Prepare the query, allow modifying by applying filter */
    $myposts_query = array(
        'post_type' => 'post',
        'post_status' => 'publish',
        'post__not_in' => array($args['post_id']),
        'suppress_filters' => false,
        'posts_per_page' => 6,
        'tax_query' => array(
            'taxonomy' => $args['taxonomy'],
            'field' => 'term_id',
            'terms' => $post_cats
        ),
    );
    $myposts = new WP_Query($myposts_query);
    if($myposts->have_posts()){
        return $myposts->posts;
    }
    else{
        return false;
    }
}

    Thanks Gagan. Can you make it fetch related posts based on tags?

    Ken,

    Just use this to fetch the posts

    $related_posts = get_related_posts_by_taxonomy (array('taxonomy'=>'post_tag'));

    Ken

    The function I wrote above is having bugs, use this function instead, I corrected it

    function get_related_posts_by_taxonomy($args) {
    $defaults = array(
        'post_id' => get_the_ID(),
        'num_posts' => 6,
        'taxonomy' => 'category',
    );
    $args = wp_parse_args($args, $defaults);

    /* Get current post's categories */
    $post_cats_temp = get_the_terms($args['post_id'], $args['taxonomy']);
    $post_cats = array();
    if (!empty($post_cats_temp)) {
        foreach ($post_cats_temp as $cat) {
            $post_cats[] = $cat->term_id;
        }
    }
    unset($post_cats_temp);
    if (empty($post_cats)) {
        return false;
    }
    /* Prepare the query, allow modifying by applying filter */
    $myposts_query = array(
        'post_type' => 'post',
        'post_status' => 'publish',
        'post__not_in' => array($args['post_id']),
        'suppress_filters' => false,
        'posts_per_page' => 6,
        'tax_query' => array(
            array(
                'taxonomy' => $args['taxonomy'],
                'terms' => $post_cats
            )),
    );
    $myposts = new WP_Query($myposts_query);
    if ($myposts->have_posts()) {
        return $myposts->posts;
    } else {
        return false;
    }
}

    This will work with categories, tags and even any custom taxonomies.

    Use this for fetching related posts with same tags

    $related_posts = get_related_posts_by_taxonomy (array('taxonomy'=>'post_tag'));
