Hello Fation,
Thanks for reaching out! What a great and difficult question. 🙂
Our plugins don’t have that option built-in and haven’t used anything like that so far.
If you would like to compare events, then this would be my thinking and approach:
The events are stored in the database as custom post types. They are basically like posts and pages. So You would need a plugin that can compare posts, including the custom post types.
I did a quick google search for “WordPress compare posts” and one of the results was this plugin:
Alike – Any post comparison WordPress
It claims that it works with every post type, so it should also work with events and possible tickets if you would like to compare those. Please note that this hasn’t been tested with our plugins yet, so I cannot guarantee full compatibility.
This is as much as I can give you at this moment. Hope it will help you get started.
Let me know if you have any further questions.
If you decide to go for that plugin we would be delighted to hear about it. Your experience might be useful for other users as well.
Cheers,
Andras
