[wp-hackers] WP 3.5.2/multisite: How to use NOT IN in $wpdb->prepare()?

[Shea Bunge]

You should have a look at the absint (http://queryposts.com/function/absint) function - it will make sure that a variable is a positive integer.
If you're dealing with an array of blog IDs, use array_map( $blog_ids, 'absint' ); (http://www.php.net/array_map) to apply the absint function to all of the array elements.
