How to autmatically switch on YARPP in bulk?

Okay - re the following code - what do I change the 'POST_TYPE_HERE' to? And anything else need changing?

Most posts in 1 of 2 different categories.

add_action('init', 'bulk_update_post_meta_data');

function bulk_update_post_meta_data() {

// guardrail: if current user can't edit posts, bail

if ( ! current_user_can( 'edit_posts' ) ) return;

$args = array(

'posts_per_page' => -1,

'post_type' => 'POST_TYPE_HERE',

'suppress_filters' => true

);

$posts_array = get_posts( $args );

foreach($posts_array as $post_array) {

$yarpp_meta['yarpp_display_for_this_post'] = 1; // YARPP value to update

update_post_meta( $post_array->ID, 'yarpp_meta', $yarpp_meta );

}

}
