How Can I hide a custom post type for a specific WordPress blog
Have a look the following example code
if ( ! function_exists( 'unregister_custom_post_type' ) ) :
function unregister_post_type() {
global $wp_post_types;
if ( isset( $wp_post_types[ 'post_type_name' ] ) ) {
unset( $wp_post_types[ 'post_type_name' ] );
return true;
}
return false;
}
endif;
$blog_id = get_current_blog_id();
if($blog_id = 1)
{
add_action('init', 'unregister_custom_post_type');
}
