Deregister custom post types

Question

Anyone know of a way to deregister custom post types ?

Is there an equivalent to register_post_type() ?

Answer 1

There's not currently an unregister_post_type function, but it's quite simple to do..

See the code provided by Nacin here.

I've no idea how WordPress will react to a built-in post type being unregistered, so do so at your own risk.. for custom post types it should be fine, simply saying that unregistering a built-in post type may have odd effects on the installation (if you were to do so).

Answer 2

As t31os noted it is easy to remove post type from global variable.

But if you mean non-core post type then it would be better to lookup code that registers it and unhook with remove_action() (if it is decent code it should be hooked rather than run directly).

Answer 3

This worked for me, like Rarst said using the remove_action() if possible.

add_action( 'after_setup_theme','remove_foundation_options', 100 );

function remove_foundation_options() {   
    remove_action( 'init', 'Orbit');    
}
