Conditional tags for wp-admin

[ericlewis]

On the front-end, we have access to conditional tags, which allows us to check which page is being requested quite declarative, and elegant.

if ( is_page( 'about' ) ) { /* do something */ }
if ( is_post_type_archive( 'people' ) ) { /* do something else */ }

In wp-admin, we're not so well equipped. You have access to $hook_suffix and get_current_screen(), both of which would require writing some more, at times tricky to craft imperative conditionals.

Some ideas:

is_post_type_list_screen() // true for a listings screen of any post type.
is_post_type_list_screen( 'post' ) // true for the posts listings screen.
is_edit_screen() // true for an edit screen of any post type.
is_edit_screen( 'post' ) // true for a post edit screen.
is_edit_screen( 13 ) // true for the edit screen of post with an ID of 13.
is_add_new_screen() // true for an add new screen.
is_add_new_screen( 'post' )
is_settings_page( 'tools' )
is_taxonomy_edit_screen()
is_taxonomy_edit_screen( 'tag' )

Hello

In which cases do you need these functions, can you provide us some examples?
Thank you

The current screen object is pretty resilient for this. I'd rather not add new top-level functions:

$screen = get_current_screen();

if ( $screen->base === 'edit' )
if ( $screen->base === 'edit' && $screen->post_type === 'post' )
if ( $screen->base === 'post' )
if ( $screen->base === 'post' && $screen->post_type === 'post' )
if ( $screen->base === 'post' && $screen->action === 'add' )
if ( $screen->base === 'post' && $screen->post_type === 'post' && $screen->action === 'add' )
if ( $screen->id === 'tools' )
if ( $screen->base === 'edit-tags' && $screen->taxonomy === 'post_tag' )

Sounds fair - closing out.
