Add a new wp_title_array filter to wp_title

[aaroncampbell]

It would be awesome to have a filter in wp_title() that would let you filter the array. Right now if any part of the title contains the title separator you can't tell what is a separator and what isn't using the wp_title filter. Additionally if we make the array filterable you could add additional parts to it without worrying about rtl vs ltr.

I can't believe this hasn't been brought up before.

+1 to this as well.

Is this still needed considering #18548?

[aaroncampbell]

Well, since #18548 doesn't actually affect wp_title we could still do this, but honestly if that one goes in I won't care about this one anymore since I'll be switching to the new way :)

I think 'wp_title_parts' or 'wp_title_sections' would be a better name for this.

17877.2.diff​ uses wp_title_parts for the filter name.

+1 for wp_title_parts.

Added filter documentation

[obenland]

Low hanging fruit.
Refreshed patch with added filter documentation.

[DrewAPicture]

The hook docs in 17877.3.diff​ look good, though I'd prefer to use "page title" instead of "document title".

[SergeyBiryukov]

In 28669:

Add 'wp_title_parts' filter to wp_title().

props aaroncampbell, obenland.
fixes #17877.
