Allow developers to filter the authors list on quick edit dropdown

[Mista-Flo]

Hello,

I want to find a way to filter the author list displayed in quick edit dropdown. I basically want to remove some roles of this list.

But there is currently no hook so I have to go through the wp_dropdown_users function, then use wp_dropdown_users_args filter, but this functions is also called on a lot of other parts of the backend, so I have to be sure that I'm only affecting the quick edit query.

So it would be nice to just add a particular filter for this quick edit author dropdown.

@SergeyBiryukov Can this one be moved forward for version 5.3 Beta 1 tomorrow? The patch looks clean. Would this need a small Dev Note as well?

[davidbaumwald]

With 5.3 Beta 1 being released today, I’m punting this to Future Release.

Hey @SergeyBiryukov I have updated my patch so it will be applied with last version of trunk. Hopefully it can now be part of 5.6 release :)

New filter. Tagging for a mention in the general dev note.

Minor refresh to improve the filter docblock and rename it quick_edit_dropdown_authors_args to coincide with the existing quick_edit_dropdown_pages_args filter.

Thanks for the enhancement @Mista-Flo I've refreshed your patch in 47685.3.diff to slightly improve the docblock and rename the filter quick_edit_dropdown_authors_args (previously quick_edit_authors_query_args) to coincide with the existing quick_edit_dropdown_pages_args filter.

I think this just needs some testing on the latest patch and it's ready for committers review.

Screen capture showing before filter is applied and when filtering 'rolein' => array( 'editor', 'administrator' ).

[hellofromTonya]

Tested with this code:

<?php

add_filter( 'quick_edit_dropdown_authors_args', function ( $users ) {
        $users['role__in']                = [ 'editor', 'administrator' ];
        $users['who']                     = '';
        $users['hide_if_only_one_author'] = false;

        return $users;
} );

Works as expected.

Removing needs-testing. This ticket is ready for commit.

Thanks for the test @hellofromTonya, looks good to me as well, thanks for the refresh @garrett-eclipse

In 49238:

Quick/Bulk Edit: Introduce quick_edit_dropdown_authors_args filter.

This allows for customizing the arguments used to generate the Quick Edit authors drop-down.

Additionally, pass the $bulk argument to the quick_edit_dropdown_pages_args filter, for consistency.

Props Mista-Flo, garrett-eclipse, hellofromTonya.
Fixes #47685.
