[Plugin: Posts 2 Posts] Querying connections via URL params

    I have having trouble querying posts using parameters passed in the URL.

    I have two custom post types I am connecting reciprocally, Athletes and Sports. For testing, I print out 1) the actual Sport ID, 2) the title and IDs of the athletes that are connected to that sport. This is done using the code:

    $athletes_query = new WP_Query(array('post_type' => 'athletes', 'connected_to' => get_queried_object_id()));
    echo get_queried_object_id();
    echo $post->ID;
    echo "<br/>";
    foreach ($athletes_query->posts as $athlete) {
        echo $athlete->post_name."-";
        echo $athlete->ID.", ";
    }

    However, when I try to perform the same query via URL (for this example, the sport I’m looking at has a post ID of 87),
    http://mysite.com/?post_type=athletes&connected_to=87
    I am given all the athletes, not just the ones I connected to the sport.

    What am I doing wrong here?

    For query variables to be used directly from the URL, they need to be registered, like so:

    function make_p2p_qv_public() {
    global $wp;

    $wp->add_query_var( 'connected_to' );
}

add_action( 'init', 'make_p2p_qv_public' );

    Thanks for getting back to me so quickly!

    I tried your snippet, but it didn’t seem to work. I inserted it into my functions.php file, logged out and logged back in just be sure, but I’m still getting all the athletes.

    I also tried the query_vars hook, but that didn’t seem to work either.

    function add_p2p_qv ($public_query_vars) {
    $public_query_vars[] = 'connected_to';
    return $public_query_vars;
}

add_action( 'query_vars', 'add_p2p_qv' );

    People seem to think a parse_request filter is also needed, but I’m not familiar enough with hooks and filters to tell.

    Any suggestions?
