Complex Configuration, Need Advice

You could create a single connection type, with a ‘primary’ custom field defined. The problem would be that the UI (a checkbox) would allow you to have multiple “primary” connections per item.

You could define 2 connection types and use the built-in ‘cardinality’ setting for one of them. In that case, you could have a person be the ‘primary’, while not necessarily having a regular ‘many-to-many’ connection, which might or might not be acceptable.

Ok, here is my configuration and it seems to be working “ok” but i’m having a few issues:

p2p_register_connection_type( array(
	'name'	=> 'company_primary_contact',
	'from'	=> $this->contacts->post_type,
	'to'	=> $this->companies->post_type,
	'title' => array(
		'to' => __('Primary Contact', IMB_I18N),
		'from' => __('Primary Contact On', IMB_I18N)
	),
	'cardinality' => 'one-to-many',
	'from_labels' => array(
		'singular_name' => __( 'Primary Contact', IMB_I18N ),
		'search_items' => __( 'Search Contacts', IMB_I18N ),
		'not_found' => __( 'No primary contact.', IMB_I18N ),
		'create' => __( 'Set Primary Contact', IMB_I18N )
	),
	'to_labels' => array(
		'singular_name' => __( 'Connected Companies (Primary)', IMB_I18N ),
		'search_items' => __( 'Search Companies', IMB_I18N ),
		'not_found' => __( 'No companies.', IMB_I18N ),
		'create' => __( 'Set Company (Primary)', IMB_I18N )
	)
) );

p2p_register_connection_type( array(
	'name'	=> 'company_contacts',
	'from'	=> $this->contacts->post_type,
	'to'	=> $this->companies->post_type,
	'title' => array(
		'to' => __('Additional Contacts', IMB_I18N)
	),
	'prevent_duplicates' => false,
	'from_labels' => array(
		'singular_name' => __( 'Contact', IMB_I18N ),
		'search_items' => __( 'Search Contacts', IMB_I18N ),
		'not_found' => __( 'No contacts.', IMB_I18N ),
		'create' => __( 'Add Contact', IMB_I18N ),
	)
) );

I’ve got this in the admin interface ok with some adjustments to labels and meta box priority, however my troubles are on the Table view. I’m actually having 2 troubles.

On my Companies page, I want a column called “contacts” and that would display the total # of connected contacts for that company. My first problem is my # is wrong. My second problem is I want a link to the Manage Contacts Admin page that only shows the connected items. Here is my code for the column:

$connection_primary = 'company_primary_contact';
$connection = 'company_contacts';
$primary = p2p_type( $connection_primary )->get_related( $post );
$related = p2p_type( $connection )->get_related( $post );
$total_contacts = count($primary->posts) + count($related->posts);

echo '<a href="'.admin_url('edit.php?post_type='.$imb_plugin->contacts->post_type).'&connected_items='.$post->ID.'&connected_type[]='.$connection_primary.'&connected_type[]='.$connection.'&connected_direction=from">'.$total_contacts.'</a>';

I wasn’t sure if calling “connected_type[]” would work, but I tried this on a different connection and I’m still getting invalid data and my links don’t work:

$connection = 'company_projects';
$related = p2p_type( $connection )->get_related( $post );

echo '<a href="'.admin_url('edit.php?post_type='.$imb_plugin->projects->post_type).'&connected_items='.$post->ID.'&connected_type='.$connection.'&connected_direction=from">'.count($related->posts).'</a>';

I realize now I was using get_related() when i needed to use get_connected()
