Meta Box

Hi,

I know the Meta Box team is on vacation, so I don't want to bother them. They deserve some time off and I'm posting this here in case anyone has encountered this or knows what to do.

I tried writing my issue out a few times with no luck, so I made a quick video trying to show the problem I'm facing.

The video: https://www.loom.com/share/144db4819f284c7eb41535bc1a9b016c

The code: https://pastebin.com/aYjmCN0q

Does anyone have suggestions or ideas on what could be going wrong?

I spoke too soon about my solution for Scholars working – it only pulls in one scholar connected to one course, regardless of any others. What do I need to change so the Advanced Select field creates options for any/all scholars in a relationship with the courses on the event?

Thank you so much for any time and assistance.

I still don't have the solution - this is still not working as wanted and assistance is still needed.

I was able to query courses connected to an event; but, only by manually inputting the Post ID. See below:

<?php
add_filter( 'rwmb_meta_boxes', 'qrsi_select_advanced' );

function qrsi_select_advanced( $meta_boxes ) {
    $prefix = '';

    $meta_boxes[] = [
        'title'      => __( 'QRSI2', 'your-text-domain' ),
        'id'         => 'qrsi2',
        'post_types' => ['events'],
        'include'    => [
            'relation'       => 'OR',
            'event-category' => [15],
        ],
        
        'fields'     => array(
            array(
                'name' => __( 'Courses Block 1', 'your-text-domain' ),
                'id'   => $prefix . 'courses_block_1',
                'type' => 'post',
                'post_type' => 'course',
                'field_type' => 'select_advanced',
                'placeholder' => __( 'Select an Item', 'your-text-domain'),
                'query_args' => array(
                    'relationship' => array(
                        'id'   => 'event-to-course-relationship',
                        'from' => 60,
                    ),
                    'post_status' => 'publish',
                    'posts_per_page' => - 1,
                    'order' => 'ASC',
                    'orderby' => 'name',
                )
            )
        )
    ];

    return $meta_boxes;
}

?>

Neither get_the_ID() or get_queried_object_id() worked. I was unable to figure out the $from and $to IDs mentioned in the documentation – there were no examples that showed how to find what the or what they would be. It just said to use them, which isn't a useful direction to provide. Nonetheless, I tried from_event-to-course-relationship and event-to-course-relationship_from as options. Neither worked.

Manually inputting the events doesn't really work for this purpose. What's the correct way to do this?

I appreciate the concern behind the reasoning of why; but, right now, I need the how more than anything. I can further expand on the reason after I get this code working as intended.

Thank you.

Nevermind – I posted this very late my time and it was painfully simple. I had the primary rule set to "Taxonomy" -> "Event Category" instead of "Post Type" -> Event. Very silly mistake on my part.
