Hi

I am trying to use pre_get_posts to filter posts based on CFS field values.

– I have posts with boolean field named _is_a_video
– I want to use pre_get_posts to limit posts only to the ones with TRUE value for _is_a_video field

The problem is I don’t know how to access the field value in the function. How to make the following code works?
```
function limit_to_video_posts($query) {
    if ($query->is_author() AND $query->is_main_query()) {
        $query->set(.....);
    }
}

add_action('pre_get_posts', 'limit_to_video_posts');
```

You don’t really need pre_get_posts to filter by custom field value. You could just use meta_query within WP_Query.

E.g.

$args = array(
  'post_type' => 'post',
  'meta_query' => array(
    array(
        'meta_key' => '_is_a_video',
        'meta_value' => 1,
    )
  )
);
$query = new WP_Query( $args );
