Posts 2 Posts limited by taxonomy terms

I have two post types (products and coaches). The products post type has a ‘product-type’ taxonomy with two term (assessments and coaching-packages). When editing a coach, I wanted two Post Type Connection boxes to appear – one for each taxonomy. It would be properly labeled and only show products with that term.

<?php
/**
* Connect Products and Coaches
*
*/
function be_p2p_connections() {
p2p_register_connection_type( array(
'name' => 'coach_assessments',
'from' => 'dietitians',
'to' => 'product',
'title' => array(
'to' => 'Connected Coaches',
'from' => 'Connected Assessments',
)
) );
p2p_register_connection_type( array(
'name' => 'coach_packages',
'from' => 'dietitians',
'to' => 'product',
'title' => array(
'to' => 'Connected Coaches',
'from' => 'Connected Coaching Packages',
)
) );
}
add_action( 'p2p_init', 'be_p2p_connections' );
/**
* Limit display of P2P metaboxes
*
*/
function be_p2p_limit_admin_box( $show, $ctype, $post ) {
$options = array(
'coach_assessments' => 'assessments',
'coach_packages' => 'coaching-packages',
);
foreach( $options as $connection_type => $term ) {
if( $ctype->name == $connection_type && 'product' == get_post_type( $post ) ) {
$terms = get_the_terms( $post->ID, 'product-type' );
if( !empty( $terms ) ) {
$terms = wp_list_pluck( $terms, 'slug' );
$show = in_array( $term, $terms );
} else {
$show = false;
}
}
}
return $show;
}
add_filter( 'p2p_admin_box_show', 'be_p2p_limit_admin_box', 10, 3 );
/**
* Limit which products show up in P2P metabox
*
*/
function be_p2p_query_args( $args, $ctype, $post_id ) {
$options = array(
'coach_assessments' => 'assessments',
'coach_packages' => 'coaching-packages',
);
foreach( $options as $connection_type => $term ) {
if( $ctype->name == $connection_type && 'dietitians' == get_post_type( $post_id ) )
$args['product-type'] = $term;
}
return $args;
}
add_filter( 'p2p_connectable_args', 'be_p2p_query_args', 10, 3 );
