I traced out the code, and it looks like the code is good. Below is the array I traced out in the create_or_get_categories function. So, it looks like the issue is related to WP’s wp_insert_category function.
Array
(
[0] => Array
(
[cat_name] => Toddler
[category_parent] =>
)
[1] => Array
(
[cat_name] => Toddler Health & Safety
[category_parent] =>
)
[2] => Array
(
[cat_name] => Heath, Complications, & Illness
[category_parent] =>
)
[3] => Array
(
[cat_name] => Autism, ADD, & ADHD
[category_parent] =>
)
)
So, it looks like this is a “feature” of the core. If you look at line 2651 of wp-includes/taxonomy.php:
$object_ids = explode(‘,’, $object_ids);
It looks like a hack to the importer is needed to alter to comma prior to injection (maybe [COMMA] or like), then update the terms table after the import is complete. This is assuming that you can have commas in category names in WP.
I spoke too soon, the problem is with line 301 of the plugin:
$items = array_map(‘trim’, explode(‘,’, $data[‘csv_post_categories’]));
I’m not sure why this is in place, but when I replace it with the below code, the categories imported properly:
$items = array_map(‘trim’, array( $data[‘csv_post_categories’]) );
As a final post, here’s what I ended up doing to preserve the ability to import multiple categories for a single post with commas in the category name:
$items = array_map(‘trim’, explode(‘|’, $data[‘csv_post_categories’]));
I just changed the delimiter to a pipe. It’s a hack, but works for my purposes.
I had the same problem,
$items = array_map('trim', explode('|', $data['csv_post_categories']));
helped. Thank you, ddimaria, that’s a good idea.
