how to format nested taxonomies,

Hey @arsenalemusica

This plugin looks unsupported but I guess this is as useful for you as it is for me. I recommend you to edit the plugin and rename it, this will prevent any possible update.

Then, in file rs-csv-importer.php after the comment [// (string, comma separated) slug of post categories] you can edit the post_category column data. I have added a simple snippet that accepts a parent > child structure.

$inserted_categories = array();
$categories = explode(', ', $post_category);
foreach ($categories as $key => $category) {
	$_categories = preg_split("/ > +/", $category);
	$cat_id = wp_create_category($_categories[0]);
	$inserted_categories[] = $cat_id;

	if (isset($_categories[1])) {
		$inserted_categories[] = wp_create_category($_categories[1], $cat_id);
	}
}
$post['post_category'] = $inserted_categories;

Hope it helps!

Regards.

oh, thank you very much for your support.
I have actually assigned my categories manually (it was tedious, as I have over 10k records) so I’m fine for the moment but I will safely keep your code in case I should make some new imports. ??
