WP Admin Bar doesn't display on wp-login.php page

[henry.wright]

I like to display the WP Admin Bar on all pages even if a user isn't authenticated because we get the WordPress logo and menu and a search button. To always show the WP Admin Bar we can do this:

add_filter( 'show_admin_bar', '__return_true' );

This will display it everywhere except wp-login.php. I think it _should_ display on this page if we return true in the filter

I think it _should_ display on this page if we return true in show_admin_bar()

I can't edit the ticket description but I should have said:

I think it _should_ display on this page if we return true in the filter.

This is because wp-login.php uses a different set of hooks. login_header and login_footer are used instead of wp_head and wp_footer

With CSS fix.

Hello @henrywright,

I attached a patch, https://core.trac.wordpress.org/attachment/ticket/48831/48831.2.diff, that should address this ticket.

P.S. - I changed this ticket from bug to enhancement as I feel that this is more of an enhancement.

Just noting there's a ​Logged Out Admin Bar plugin used on WordPress.org for that purpose, though it doesn't display the toolbar on the login page either.

@donmhico I think you are right to set this to an enhancement. It isn't really a bug

Thanks @SergeyBiryukov

check that filter returns true and that the page is not an interim login

Latest iteration: 48831.3.diff​

I moved the actions into wp-login.php so it checks whether the filter returns true (not every case of showing toolbar). The toolbar also does not fit in an interim login.

For the CSS, I prefer resetting form element styles along with the links, and the search input min-height matches the height. The html element includes an admin-bar class so the full height layout can subtract the toolbar height from 100% (using the new custom property).
