Hide/Exclude a Page in Edit Pages Section in WordPress Dashboard

If you’re searching for a way where you can tailor the admin dashboard pages (Edit Pages Section). Let’s take an example:

You have a blog page on a WordPress site, but that blog page is fed from posts in the post section. And you want to remove that Blog page from the pages section. Following is a tip to exclude or hide a page from edit pages section. Let’s say page ID is “15“.

add_action( 'pre_get_posts' ,'exclude_this_page' );
function exclude_this_page( $query ) {
if( !is_admin() )
return $query;
global $pagenow;
// WordPress 2.9
if( 'edit-pages.php' == $pagenow )
$query->set( 'post__not_in', array(15) );

// WordPress 3.0
/*
if( 'edit.php' == $pagenow && ( get_query_var('post_type') && 'page' == get_query_var('post_type') ) )
$query->set( 'post__not_in', array(15) );
*/
return $query;
}
