Add post_type_supports filter

[mitchoyoshitaka]

The post_type_supports return value should be filter-able, and there's even a @todo in the code to that effect.

I'm thinking that $args as in array_slice( func_get_args(), 2 ); should get passed along. That can be quite helpful. As an example, we use it for post thumbnails by post type. We can also remove the otherwise commented code.

Couldn't the same effect be achieved by using add_post_type_support() and remove_post_type_support() ?

There's no filter on current_theme_supports() either.

Replying to scribu:

There's no filter on current_theme_supports() either.

The use case I'm thinking of is for enforcing a certain combination of support features, or disallowing certain combinations. In particular, for ​this plugin, I want to ensure that post types that support 'xmldoc' do not support 'editor'. I don't think there's a good way to do that right now... filtering on add_post_type_support would be an alternative, though, but I think this has more flexibility.

Patch v2, passing all args using array_slice

i also think this would be quite useful. i'm using the verve meta boxes plugin and the gd custom posttypes plugin and want to have a post type which does not "support custom fields" - that is that it would not display that meta box, but i would like to be able to add a custom meta box on the side using the verve plugin. rather than rewriting the verve meta plugin i think it would be easier to get the desired behavior using this filter. so +1

This is basically obsolete since [23722] - use add_post_type_support()

@wonderboymusic how would that work for the scenario presented in comment:3?

[wonderboymusic]

When all of the post types are registered, you can remove the support for editor from the types that support xmldoc using those funcs - turning off support on the fly isn't a feature I see a lot of people screaming for. I remember when Mitcho was talking about this stuff in SF in 2011 at WordCamp. If he wants to reopen the ticket, he can.
