Custom taxonomy meta box callback

[johnbillion]

I'd like to be able to specify my own meta box function for my custom taxonomies.

Currently if I want to specify my own meta box for my custom taxonomy, I must set the public parameter to false and then add my own meta box using add_meta_box(). It would be nice to just do this with a callback function parameter in register_taxonomy().

Example:

register_taxonomy( 'foo', 'bar', array(
    'meta_box_callback' => 'my_meta_box'
) );

I'll write up a patch if there's a chance of it going in.

+1 on the idea.

Just to avoid confusion, in register_post_type() there's a 'register_meta_box_cb' argument which receives a callback. In that callback, you are supposed to call add_meta_box() or remove_meta_box(), as necessary.

[garyc40]

there's a patch for that

[scribu]

This can wait.

This appears to work for me in 3.5 out-of-the-box. Has the patch been silently added to the repo without updating this ticket?

[scribu]

There is no code in 3.5 for handling the 'meta_box_callback' argument. You probably have a plugin installed or something.

The name is different, but it appears that the same functionality is referenced in wp-includes/post.php around line 1178 and 1336

you're looking for 'register_meta_box_cb'

[scribu]

The idea was to pass the callback directly to register_taxonomy(), whereas 'register_meta_box_cb' is an argument you pass to register_post_type().

Refreshed against trunk

I'm hesitating a bit on this because of the difference between register_meta_box_cb and meta_box_callback. It is clear why the different functionality is needed — you may want to add a bunch of meta boxes for a single post type, while this is for replacing the taxonomy box — but the names are too similar. Explaining what register_meta_box_cb does is kind of awkward as it is.

I think we can solve this by clearly documenting the meta_box_callback parameter (missing from this patch) and seeing if the documentation for register_meta_box_cb can be improved as well.

14206.2.diff​ - refreshed, added and massaged some docs. Renamed it meta_box_cb to parallel register_meta_box_cb. I agree that they're similar, but perhaps keeping the same base of the name will indicate that they function differently on purpose.

​nacin says he will test and get it in. Really, I just wanted to link to that chat log.

[ocean90]

meta_box_cb looks good for me too. +1 for 14206.2.diff​.

[nacin]

In 25572:

Introduce a meta_box_cb argument for register_taxonomy().

The specified callback function is used as the meta box callback for the taxonomy.

props garyc40, helen.
fixes #14206.

I wonder if we should also allow boolean false in the meta_box_cb argument to disable the meta box?

#21543 was marked as a duplicate.

I think we should - using #21543 for that.
