Search Posts, attachment limits and attaching Terms

[lmartins]

While really useful as it is, I believe it could really improve with a few changes:

1. Search posts
   I've noticed theres a field dedicated to that functionality, but something in the lines of what ACF does would be really awesome. When you have a lot of posts, the current presentation won't scale well, hence the need for some sort of search functionality.
2. Limit Attachments
   Would be possible to limit ao many attachments the user can add?
3. Attaching Terms
   It would be very useful if we could attach other types of contents, such as categories, custom post-types, etc.

Thank you CMB2 and this useful extension.

1. My goal is to eventually combine this library with the
   CMB2 Post Search field type.
2. Interesting idea. It'll likely sit on the back-burner till we need it for a certain project, but if you care to submit a PR, we'd be happy to look at it.
3. You can definitely modify the query args if you follow the example and have it use any post-type you want. That being said, other types of data would be a cool option.

Yeah! Combining this with "Post Search Field Type" would be reallllllly useful.

I just got this installed, in which to attempt to create kind of curated/arranged "guides" of existing posts/pages/etc, but it's not really possible because I can't find the content in which to add. And it doesn't look like I can switch to "Post Search" field type, because then I lose the ability to re-arrange.

Let's see if I can whip something up

Ok, the deed is done. Let me know how it works for you guys.

If you're familiar with the pre_get_posts hook, and the $query object, you can modify the search modal's results by specifying a callback on the 'attached_posts_search_query_cb' field parameter. (similar to other *_cb parameters). The callback gets the $query object passed to it.

this is sweet - best of both worlds. Now we can set up queries to prefill the list with relevant stuff on load AND use search.

Awesome!
