Posts 2 Posts Relationships

説明

This plugin allows you to create many-to-many relationships between posts of any type: post, page, custom post types, etc.

Configure post 2 post connections easily in a friendly interface.

The new connection metaboxes will appear on the related post edition pages. Search text, post type and term combo filter available as option for it.

Use the standard WP_Query() and get_posts() to get the related posts.

Solid-rock relationships: use his own database table, updated on post status change and removed on post deletion.

Getting related: the WP_Query way

// inside main loop, current post ID (p2p_rel_post_id) not needed, current post will be used if you don't set it:

$args = array(
    'p2p_rel_key'        => 'prod_to_bars',  // This is your connection key name. Required.
    'p2p_rel_post_id'    => 1,               // The post ID. Inside main loop dont needed.
    'p2p_rel_direction'  => 'any',           // The connection direction. 'any' by default. Optional. Explained below. ( can be 'any' | 'from_to' | 'to_from' )

    // Of course, here you can add the standard WP arguments you need: post type, status, dates, pagination, etc.
); 

// (at this point, as any other WP looping):

// The Query 
$the_query = new WP_Query( $args );

// The Loop
if ( $the_query->have_posts() ) {
    echo '<ul>';
    while ( $the_query->have_posts() ) {
        $the_query->the_post();
        echo '<li>' . get_the_title() . '</li>';
    }
    echo '</ul>';
} else {
    // no posts found
    echo '<p>Nothing related</p>';
}

// Restore original Post Data 
wp_reset_postdata();

Getting related: the get_posts() way

// inside main loop, current post ID (p2p_rel_post_id) not needed, current post will be used if you don't set it:

$args = array(
    'p2p_rel_key'        => 'prod_to_bars', // This is your connection key name. Required.
    'p2p_rel_post_id'    => 1,              // The post ID. Inside main loop dont needed
    'p2p_rel_direction'  => 'any',          // The connection direction. 'any' by default. Optional. Explained below. ( can be 'any' | 'from_to' | 'to_from' )
    'post_type'          => 'any',          // The filtered post types, can be an array. Optional. 'post' by default. (can be 'any' for all)
    'suppress_filters'   => false           // Required

    // Of course, here you can add the standard WP arguments you need: post type, status, dates, pagination, etc.
); 

// (at this point, as any other WP looping):

$rel_posts = get_posts ( $args );

print_r( $rel_posts );

Getting related: getting it raw

// inside main loop, current post ID (element_id) not needed, current post will be used if you don't set it:

$args = array(
    'key'           => 'prod_to_bars',  // This is your connection key name. Required.
    'element_id'    => 1,               // The post ID. Inside main loop dont needed.
    'element_type'  => 'any',           // The filtered post types, can be an array. Optional. 'post' by default. (can be 'any' for all)
    'status'        => 'any'            // The filtered post status, can be an array. Optional. 'publish' by default. (can be 'any' for all)
    'direction'     => 'any',           // The connection direction. 'any' by default. Optional. Explained below. ( can be 'any' | 'from_to' | 'to_from' )
); 

global $P2P_Relationships;
$rel_posts = $P2P_Relationships->get_raw ( $args );

// Only an array of related post IDs, not the posts objects.
print_r ( $rel_posts ); 

The connection direction

By default, the connections are bidirectional (any). However, you can get related posts only in one direction: ‘from_to’ or ‘to_from’.

You can do the same logic at interface level for your users in the backoffice: you can setup your connection hidding the from metabox or the to metabox (UI mode setting).

FAQ

Is this plugin an add-on for Advanced Custom Fields (ACF)?

No. This plugin is an stand-alone add-on for WordPress. However, it cover the gap of ACF about many-to-many post connections, and can be used together.

Where are the post connections stored?

This plugin store connecitons in his own table on database, instead of post meta.

This gives you a more efficient queries and a solid-rock connections consistency.

The DB table is named: {WP prefix}p2p_relationships

Double metabox issue on post edition pages

If you need relationships between posts and posts, or products and products, etc. Hide one of two metaboxes (UI mode setting) to avoid double metabox issue (FROM and TO same metaboxes relation in the same page).
