Prevent pages or posts from being deleted in WordPress

To stop any page from being deleted by any user role, including admins, add the following code to your functions.php file.

Update the $post_id variable to the ID of the page or post you want to protect from deletion.

function prevent_views($allcaps, $caps, $args) {
    $post_id = 6293;
    if ( isset( $args[0] ) && isset( $args[2] ) && $args[2] == $post_id && $args[0] == 'delete_post' ) {
        $allcaps[ $caps[0] ] = false;
    }
    return $allcaps;
}
add_filter ('user_has_cap', 'prevent_views', 10, 3);
