Redirect single pages of post type in to post type archive page - WordPress

In WordPress, if our post type is public, in default, a single page view will be available for all posts in that post type.

If we don’t need a single view of post type, it is better to make post type, not as public. In register_post_type hook, there is an argument called public & we have to set that value as false.

But now I need to make one of my custom post types as public & the same time, I need to remove the single page view of that custom post type. Below you can find the code snippet that I have used for that purpose.

add_action( 'template_redirect', function() {
	$post_type = 'board_member';
	if ( is_singular($post_type) ) {
		global $post;
		$redirectLink = get_post_type_archive_link( $post_type );
		wp_redirect( $redirectLink, 302 );
		exit;
	}
});
