How to extend show_on

    I understand that you can use show_on_cb returning a bolean to extend show_on which only uses post_id / template.

    But I am a little unsure how to achieve this. I want to just have the meta box on homepage when in admin. I can use page ID but intherory that may change

    I tried (is_home()||is_front_page()) but this didn’t work, I guess as conditional tags don’t apply in the back end?

    What am I doing wrong?

    Btw I have worked out how to write a custom ‘show on static front page’ for calls from show_on_cb

    e.g.

    function my_show_on_static_front_page(){
    global $post;
    return ($post->ID == get_option( 'page_on_front' ));
 }

    However, I have discovered a bug (feature?) that show_on_cb works fine on normal fields but on group fields, not so. AM I doing something wrong here?

    I think the show_on_cb led me up the garden path for this solution.

    show_on_cb doesn’t appear to work on ‘new_cmb2_box’ and ‘add_group_field’ only on ‘add_field’ (tested with hard coded logic)

    But the solution I actually wanted was simple, after the fact, ignore show_on_cb and just use show_on thus

    'show_on'      => array( 'id' => array( get_option( 'page_on_front' ), ) ),

    Which version are you using? show_on_cb works on grouped fields as well. Also, I just added the show_on_cb parameter for new_cmb2_box, and should be in the next release. And you’re right, conditional tags do not apply in the backend, but you are using the right solution.

    Hi Justin,

    version 2.0.2

    My ‘bad’ I was trying to use show_on_cd on

    $group_field_id = $cmb_meta->add_field

    which still returns the id (maybe it shouldn’t?)

    where as using shown_on_cb on add_group_field does work
