Problem:
The user is following this tutorial to create a comparison page https://www.youtube.com/watch?v=oSuY4QF812s
When he selects more than 2 posts, the view works as expected. When he selected one post or none, the view displays all the posts.

Solution:
We'll need to implement a custom code that will check how many posts are passed to the comparison page. Then we can conditionally display the comparison view or a message.
This a sample code for the shortcode:

add_shortcode( 'compared-post-ids-count', 'compared_post_ids_count_func' );
function compared_post_ids_count_func () {
  $post_ids = isset( $_GET['post_ids'] ) ? $_GET['post_ids'] : array();
  return sizeof( $post_ids );
}

The shortcode needs to be registered in Toolset->Settings->Front-end Content to be used in conditions.

Then we can display a view or a message, like this:

[wpv-conditional if="( [wpv-search-term param='post_ids'] ne '' )"][wpv-view name="scholen-vergelijken-po"][/wpv-conditional]
 
[wpv-conditional if="( [wpv-search-term param='post_ids'] ne '' )" evaluate="false"]You will need to select at least two posts to compare[/wpv-conditional]
