Hi,
I did the migration for more than 500 posts from my old site to my new own.

I installed Members plugin before that. Now, these posts are without roles.
I’d like to assign some specific roles programmatically, I prefer don’t modify every single post 🙂

I tried this loop:

<?php
require_once('wp-load.php');
 
if ( !is_user_logged_in() && !current_user_can('manage_options')) {
	die('Please login as admin to use this page.');
}

$roles = array('administrator','author','support');

// the query
$wpb_all_query = new WP_Query(array('post_type'=>'post', 'post_status'=>'publish', 'posts_per_page'=>-1)); 

if ( $wpb_all_query->have_posts() ) : 
?>
<ul>
    <?php while ( $wpb_all_query->have_posts() ) : $wpb_all_query->the_post(); 
		members_set_post_roles( the_ID(), array_map( 'members_sanitize_role', $roles ) );		
	?>
    <li><a href="<?php the_permalink(); ?>"><?php the_title(); ?></a></li>
    <?php endwhile; ?>
</ul>
	<?php wp_reset_postdata(); 
 
 else : ?>
    <p><?php _e( 'Sorry, no posts matched your criteria.' ); ?></p>
<?php endif; ?>

I put this file.php into my installation root. It’s print all post Title and I have this warning, but nothing happened to posts’ roles.
Warning: in_array() expects parameter 2 to be array, boolean given in /home/wpwebsit/public_html/PMSknow/wp-content/plugins/members/inc/functions-content-permissions.php on line 105

Can someone help me to do this?
THANKS

Regards
