[wp-hackers] Multisite global user setting reset

[Drew]

You can hook into the 'edit_posts_per_page' filter in
class-wp-posts-list-table.php.
It covers any/all pages (afaik) regardless of whether a post_type is passed.

Something like this should work. It's set to max at 20, but allows fewer:

/**
>  * Force all the things to 20 max X per page.
>  *
>  * @param int    $per_page  The number of items to show per page.
>  * @param string $post_type The post type.
>  *
>  * @return int Filtered number of items to show per page.
>  */
> function force_per_page( $per_page, $post_type ) {
>     return $per_page >= 21 ? 20 : $per_page;
> }
> add_filter( 'edit_posts_per_page', 'force_per_page', 10, 2 );
