WP_Query Connections Between Posts - php

Question

I'm using the Posts 2 Posts plugin. I have many different post types and many different connection types.
I create all those relationships like so
function register_post_type_connections() {
$connection_post_types = array('person', 'nonprofit', 'business', 'article', 'event', 'structure', 'government');
foreach($connection_post_types as $post_type){
p2p_register_connection_type( array(
'name' => $post_type .'_to_structure',
'from' => $post_type, // use $my_post_types if you didn't define $temp_array
'to' => 'structure',
'reciprocal' => false,
'duplicate_connections' => true,
'sortable' => true,
));
}
// Foreach repeated for each $connection_post_types
}
add_action( 'p2p_init', 'register_post_type_connections' );
The foreach loops is repeated 7 total times in this function to get every possible combination. I've tested the result and it works correctly
Many connections are made and attached to individual post pags. I want to show a list of all these connections made.
I get a complete list of all the connection types like this
function get_all_connection_types() {
$connection_types = array();
$connection_post_types = array('person', 'nonprofit', 'business', 'article', 'event', 'structure', 'government');
foreach($connection_post_types as $post_type){
$connection_types[] = $post_type .'_to_person';
$connection_types[] = $post_type .'_to_nonprofit';
$connection_types[] = $post_type .'_to_business';
$connection_types[] = $post_type .'_to_article';
$connection_types[] = $post_type .'_to_event';
$connection_types[] = $post_type .'_to_structure';
$connection_types[] = $post_type .'_to_government';
}
return $connection_types;
}
Then I run my loop
$post_types = array('person', 'nonprofit', 'business', 'article', 'event', 'structure', 'timeline', 'government');
$connection_types = get_all_connection_types();
$connected = new WP_Query( array(
'connected_type' => $connection_types,
'post_type' => $post_types,
'connected_items' => 'any',
'connected_direction' => 'to',
'posts_per_page' => 20,
'orderby' => 'meta_value',
'connected_orderby' => 'date',
'connected_order' => 'desc'
) );
echo '<ul>';
if ( $connected->have_posts() ) {
while ( $connected->have_posts() ) :
$connected->the_post();
Here are my connections from the database
My loops is only returning person_to_person connections. So I tested by changing connected_type to..
$connection_types = array('person_to_structure', 'person_to_person');
This gives me the person_to_structure connections but not the person_to_person.
Why?

Answer 1

You need to pass "connected_direction" as array with exact length of that "connected_type" has for this change this code on your index file.
$post_types = array('person', 'nonprofit', 'business', 'article', 'event', 'structure', 'timeline', 'government');
$connection_types = get_all_connection_types();
$direction_array = array();
for($i=0;$i<count($connection_types);$i++) {
$direction_array[$i] = 'from'; // if you want then you can send the from as well;
}
$connected = new WP_Query( array(
'connected_type' => $connection_types,
'post_type' => $post_types,
'connected_items' => 'any',
'connected_direction' => $direction_array,
'posts_per_page' => 20,
'orderby' => 'meta_value',
'connected_orderby' => 'date',
'connected_order' => 'desc'
) );
This will work.
