I'm currently using code like this:
\add_filter( 'the_content', 'filter_keywords' );
And it works with my filter_keywords function to change the output of default Post or Page content.

But I would also like to filter text stored and displayed from post meta custom fields. For example, I have a custom field called extra_info that I would like to run through my filter_keywords filter.

What would be the MetaBox.io way to do this? I've tried doing something similar to add_filter( 'rwmb_meta',... at the bottom of this page: https://docs.metabox.io/filters/rwmb-the-value/ - but not having any luck.

Thank you.

I think I was having an issue with priority and shortcodes. This seems to be working now, but if there is a better or more preferred way, I'm interested to know. Thank you!
```
add_filter( 'rwmb_meta', function( $value, $field_id, $args, $object_id ) {
    // look for my custom fields
    $filterThese = array('extra_info','user_notes','manager_notes');
    if ( in_array($field_id, $filterThese, true) ) {
        // run my custom field values through the filter
        return filter_keywords($value);
    }
    return $value;
}, 99, 4 );
```

Hello Brandon,

Thanks for sharing the solution.

I see it is the correct way to filter the field value when outputting with the helper function rwmb_meta(). Refer to the documentation https://docs.metabox.io/filters/rwmb-meta/
