Meta Box

There are a couple problems with this doc. One is that the JS looks for #map_ID and the html provides id="map". I worked through that.

Once that's fixed we get this error:
Uncaught Error: Set map center and zoom first.

This despite the fact that they are indeed set. I don't know JS well enough to debug this. Any ideas?

Yes, that's what I'm talking about, there's no UI under the advanced tab.

Yes, I know, it's coming from the map code, and I'm asking WHY it's there. As you can see in the code above, there is no anchor tag.

I figured it out. I had some logic dictating when my class was instantiated. It was there for the front of the admin page, but not there for submission. I loosened the logic and it works fine.

Closing this. We didn't really fix the query, I THINK it was erroring because I was trying to detect a connection where there wasn't one. This was causing an IN statement with no IDs, which MariaDB gave an error on, but MySQL did not.

The way I "fixed" it was putting in more tests to make sure it was only looking for a connection on pages that really should have one, and THEN storing the object it got back in meta on the post.

DO NOT fetch this meta in the admin area, catastrophic error loss will occur.

I have the ID of the post I'm on, how do I know the ID of the other end, to check?

In other words, I want to know if current post is connected to ANY of the other post type.
