I have a meta like this:
```
array(
				'name'        => __( 'Related proceedings', 'textdomain' ),
				'placeholder' => __( 'Select the related proceedings', 'textdomain' ),
				'id'          => "{$prefix}related_prod",
				'type'        => 'taxonomy',
				'taxonomy'    => 'category',
				'field_type'  => 'select_advanced',
				'add_new'     => true,
			),
```
How could set up a value to this meta field?
I've tried with rwmb_set_value but I couldn't manage to work.

Hi,

Please follow the sample code in the documentation to know how to set a taxonomy field value.
https://docs.metabox.io/functions/rwmb-set-meta/
```
add_action( 'init', function() {
    rwmb_set_meta( 123, 'related_prod', 456 );
}, 99 );
```
where 123 is the post ID
456 is the term ID
and check the correct field ID related_prod (with prefix).
