Filter for visualization of terms list in admin tables

[DaveFX]

While trying to customize the list of terms for a given post in the admin posts list table, I've found that there's no available filter for that.

Here I'm adding a patch adding a new filter to allow this customization.

New version of the patch.

Added new version for the patch, so how it mimics the behaviour of "term_links-{$taxonomy}" filter.

Hello,

5.0.3 is going to be released in a couple of weeks. We are currently sorting the remaining tickets in the milestone.

The ticket adds a new filter and still needs a dev-feedback/second-opinion. Since 5.0.3 is going to be a "normal" minor with only self-contained patches and regression/bug fixes. Let's address this ticket in 5.1 which is scheduled for February.

@DaveFX: It seems like the functionality you're after would be better done using the get_the_terms filter. Perhaps with a get_current_screen() check to ensure you're on the right screen, if you just want to filter in the post list table.

[DaveFX]

@pento I respectfully disagree. By using the get_the_terms filter we would only be able to customize the list of terms returned. But what we want to achieve with this patch is customizing the output of the shown terms, not the actual list of terms.

For example, we want to show only one of the terms using a bold font-weight.

Thanks for the patch and for your patience, @DaveFX.

I agree that a get_the_terms filter is not enough in this case, and it seems reasonable to want to filter these links.

42669.diff​ renames the filter to avoid a dynamic filter name, and to better match other post_column filters. $taxonomy is passed as an argument instead. I've also passed $terms and renamed some variables to be more transparent. Does this seem appropriate to you?

[DaveFX]

Thank you, @boonebgorges.

Yes, your changes look good for me.

In 44822:

Taxonomy: Introduce post_column_taxonomy_links.

This filter allows plugin developers to modify the markup for the links
in taxonomy columns on edit.php.

Props DaveFX.
Fixes #42669.
