Custom Taxonomies not associated to Custom Post Type on Export

[jeffikus]

When I export my blogs data including all the Custom Post Types and the associated Custom Taxonomies, and I import on the other wordpress blog, the Custom Taxonomies are not assigned back to the Custom Post Type and the hierarchy of the custom taxonomies have been lost (although they are imported).

I have read ​http://wordpress.org/support/topic/412612?replies=2 and no one has responded to this. I have specified 'can_export' => true in the register_post_type() declaration. Also, this has apparently been fixed in ​http://core.trac.wordpress.org/ticket/12180 yet I am having the same issue.

I have tried other taxonomy plugins, including GD Custom Posts And Taxonomies Tools and they all give the same issue.

If you want more info I can send you the code/data.

Hi Jeffikus,

I've also had this problem. I'm not sure how to submit a patch, exactly, but I think I've found a fix.

In /wp-admin/includes/export.php, there's a function wxr_post_taxonomy() about line 253

Replace this:

$taxonomies = get_object_taxonomies( 'post' );
$terms = wp_get_post_terms( $post->ID, $taxonomies );

With this:

$taxonomies = get_object_taxonomies( $post->post_type ); 
$terms = wp_get_object_terms($post->ID, $taxonomies);

See if that fixes your issue?

Hope I did that right! Can anyone confirm?

Looks good.

Not sure what to update on here, but I can confirm this fix works.

We only close tickets once they have been committed to core.

(In [15961]) Importer and exporter overhaul, mega props duck.

Exporter overhaul:

• Add author information to export
• Greater usage of slug identifiers
• Don't export auto-drafts, spam comments, or edit lock/last meta keys
• Inline documentation improvements
• Remove filtering for now (@todo)
• Bump WXR version to 1.1, but remain back compat in the importer

Importer overhaul (​http://plugins.trac.wordpress.org/changeset/304249):

• Use an XML parser where available (SimpleXML, XML Parser)
• Proper import support for navigation menus
• Many bug fixes, specifically improvements to category and custom taxonomy handling
• Better author/user mapping
