Dear Agnes,

Thank you for your reply.
I’m afraid but I think Post 2 Postplugin leaves us more parts we can coding.

So, I decided to try to make it with Post 2 Post plugin, but again I have some problem.

I added

/**
 * Related Post Connection
 * @author Bill Erickson
 * @link https://www.billerickson.net/manually-curated-related-posts/
 *
 * @uses Posts2Posts
 * @link https://github.com/scribu/wp-posts-to-posts/wiki
 */
function be_post_type_connections() {

	p2p_register_connection_type( array(
		'name' => 'related-articles', // unique name
		'from' => 'post',
		'to' => 'post',
		'title' => array( 'to' => 'All Connections', 'from' => 'Related Articles' )
	) );
}
add_action( 'p2p_init', 'be_post_type_connections' );

/**
 * Related Posts Before Loop
 * Adds connection data to $wp_query. Run before the loop.
 *
 * @author Bill Erickson
 * @link https://www.billerickson.net/manually-curated-related-posts/
 */
function be_related_posts_pre_loop() {
 	// Make Sure plugin is active
 	if ( !function_exists( 'p2p_register_connection_type' ) )
		return;

	global $wp_query;
	p2p_type( 'related-articles' )->each_connected( $wp_query );
}
/**
 * Display Related Posts
 * @author Bill Erickson
 * @link https://www.billerickson.net/manually-curated-related-posts/
 */
function be_related_posts() {
 	// Make Sure plugin is active
 	if ( !function_exists( 'p2p_register_connection_type' ) )
		return;

	global $post;
	if( isset( $post->connected ) && !empty( $post->connected ) ):
		echo '<div class="related-posts">';
		$count = 1;
		foreach( $post->connected as $related ):
			if( $count < 6 ) {
				echo '<div class="related-post">';
				echo '<a class="image" href="' . get_permalink( $related->ID ) . '">';
				$cat = wp_get_object_terms( $related->ID, 'category', array( 'count' => 1 ) );
				echo '<span class="category">' . $cat[0]->name . '</span>';
				echo get_the_post_thumbnail( $related->ID, 'be_home_small' );
				echo '</a>';
				echo '<a class="title" href="' . get_permalink( $related->ID ) . '">' . $related->post_title . '</a>';
				echo '</div>';
				$count++;
			}
		endforeach;
		echo '</div>';
	endif;
}

to my function.php but the related posts never appears on each posts.

If you know about this, I beg your ideas.
