rwmb_ajax_get_posts

This filter changes the items that the post field gets via Ajax (when ajax is true). The field shows these items in the dropdown when users search or scroll.

apply_filters( 'rwmb_ajax_get_posts', $items, $field, $request );

It has 3 parameters:

Name	Description
`$items`	Array of items. Each item is an array with `value` (post ID), `label` (post title) and `parent` (parent post ID).
`$field`	Field settings
`$request`	The `RWMB_Request` object. Use `$request->filter_post( 'term' )` to get the search keyword.

Other fields that get items via Ajax have similar filters:

rwmb_ajax_get_terms: for the taxonomy and taxonomy_advanced fields. Each item has value (term ID), label and parent.
rwmb_ajax_get_users: for the user field. Each item has value (user ID) and label.
rwmb_ajax_get_models: for the model field of MB Custom Table.

Examples

Add the post date to the labels:

add_filter( 'rwmb_ajax_get_posts', function ( $items, $field, $request ) {
    if ( 'related_event' !== $field['id'] ) {
        return $items;
    }
    foreach ( $items as &$item ) {
        $item['label'] .= ' (' . get_the_date( 'Y-m-d', $item['value'] ) . ')';
    }
    return $items;
}, 10, 3 );

Remove users with the "subscriber" role from the results:

add_filter( 'rwmb_ajax_get_users', function ( $items, $field, $request ) {
    return array_values( array_filter( $items, function ( $item ) {
        return ! in_array( 'subscriber', get_userdata( $item['value'] )->roles, true );
    } ) );
}, 10, 3 );

To change the query (not the results), use the field's query_args setting instead.
