Issue with multiple post-types with same taxonomy :: Two post-types can't have same taxonomy

[manojhl]

i created two objects $book and $person, and an taxonomy author_type.

$books->register_taxonomy(array(
    'taxonomy_name' => 'author_type',
));
$person->register_taxonomy(array(
    'taxonomy_name' => 'author_type',
));

but the taxonomy is available for only the last declared object $person but $books did't get the auther_type taxonomy...

I don't know may be i am doing something wrong..

When registering the taxonomy to another post type this way, the class uses register_taxonomy_for_object_type (codex), which doesn't seem to be working as expected. I think the taxonomy gets registered to the post type, its the UI doesn't display. So I'll look into fixing this bug when I can.

For now, you could try registering the taxonomy to the post type within its arguments array (codex) like so:

$person = new CPT('person', array(
    'taxonomies' => array('author_type')
));

This should work :)

I have already tried that but this one also registers the taxonomy once again :D, I took into the register_taxonomy_for_object_type inside core, everything looks fine but don't know the registered taxonomies aren't added in the $wp_taxonomies global.. May be you should localize this global variable inside the CTP itself.....

That's cool man I tried for hours and thought its not possible and moved on but you finally got the solution.
Can you give me brief what was causing that error.

The add_action to register the taxonomies was inside the register_taxonomy method of the class, I think this meant the action wasn't registered early enough to run properly and register taxonomies correctly.

By moving the add_action into the __construct method of the class registers the action and taxonomies correctly.

Hope that makes sense :)
