how to allow a role editor to manage woocommerce taxonomies in worpdress?

if you read this, you can see that woocommerce recommend two plugins to work, try: this or this

Or try adding this capabilities

1. manage_product_terms
2. edit_product_terms
3. delete_product_terms
4. assign_product_terms
5. manage_categories

You can also do this programmatically like you were trying to, however there are several more roles you must grant for it to work.

I found this out by querying the Woocommerce Shop Manager role, and comparing the capabilities with the editor role.

Here's the code to add the whole lot (at time of writing):

    //add caps to editor role    $role = get_role("editor");    //for woocommerce    $role->add_cap("manage_woocommerce");    $role->add_cap("view_woocommerce_reports");    $role->add_cap("edit_product");    $role->add_cap("read_product");    $role->add_cap("delete_product");    $role->add_cap("edit_products");    $role->add_cap("edit_others_products");    $role->add_cap("publish_products");    $role->add_cap("read_private_products");    $role->add_cap("delete_products");    $role->add_cap("delete_private_products");    $role->add_cap("delete_published_products");    $role->add_cap("delete_others_products");    $role->add_cap("edit_private_products");    $role->add_cap("edit_published_products");    $role->add_cap("manage_product_terms");    $role->add_cap("edit_product_terms");    $role->add_cap("delete_product_terms");    $role->add_cap("assign_product_terms");    $role->add_cap("edit_shop_order");    $role->add_cap("read_shop_order");    $role->add_cap("delete_shop_order");    $role->add_cap("edit_shop_orders");    $role->add_cap("edit_others_shop_orders");    $role->add_cap("publish_shop_orders");    $role->add_cap("read_private_shop_orders");    $role->add_cap("delete_shop_orders");    $role->add_cap("delete_private_shop_orders");    $role->add_cap("delete_published_shop_orders");    $role->add_cap("delete_others_shop_orders");    $role->add_cap("edit_private_shop_orders");    $role->add_cap("edit_published_shop_orders");    $role->add_cap("manage_shop_order_terms");    $role->add_cap("edit_shop_order_terms");    $role->add_cap("delete_shop_order_terms");    $role->add_cap("assign_shop_order_terms");    $role->add_cap("edit_shop_coupon");    $role->add_cap("read_shop_coupon");    $role->add_cap("delete_shop_coupon");    $role->add_cap("edit_shop_coupons");    $role->add_cap("edit_others_shop_coupons");    $role->add_cap("publish_shop_coupons");    $role->add_cap("read_private_shop_coupons");    $role->add_cap("delete_shop_coupons");    $role->add_cap("delete_private_shop_coupons");    $role->add_cap("delete_published_shop_coupons");    $role->add_cap("delete_others_shop_coupons");    $role->add_cap("edit_private_shop_coupons");    $role->add_cap("edit_published_shop_coupons");    $role->add_cap("manage_shop_coupon_terms");    $role->add_cap("edit_shop_coupon_terms");    $role->add_cap("delete_shop_coupon_terms");    $role->add_cap("assign_shop_coupon_terms");    $role->add_cap("edit_shop_webhook");    $role->add_cap("read_shop_webhook");    $role->add_cap("delete_shop_webhook");    $role->add_cap("edit_shop_webhooks");    $role->add_cap("edit_others_shop_webhooks");    $role->add_cap("publish_shop_webhooks");    $role->add_cap("read_private_shop_webhooks");    $role->add_cap("delete_shop_webhooks");    $role->add_cap("delete_private_shop_webhooks");    $role->add_cap("delete_published_shop_webhooks");    $role->add_cap("delete_others_shop_webhooks");    $role->add_cap("edit_private_shop_webhooks");    $role->add_cap("edit_published_shop_webhooks");    $role->add_cap("manage_shop_webhook_terms");    $role->add_cap("edit_shop_webhook_terms");    $role->add_cap("delete_shop_webhook_terms");    $role->add_cap("assign_shop_webhook_terms");

Note that this will add FULL capabilities in woocommerce for all editors.

To check that you don't need additional roles, compare these with the capabilities granted to the shop manager role like so:

    $role = get_role("shop_manager");    print_r($role->capabilities);

Sorry, I'm a little late to the party. I wanted to share this snippet for debugging user roles, it has helped me greatly.

add_action( 'admin_notices', 'debug_user_roles' );function debug_user_roles() {  global $pagenow;  if( $pagenow == 'index.php' ) {    $MYrole = get_role("seo_specialist");    echo '<pre>';    print_r($MYrole->capabilities);    echo '</pre>';    $MY_other_role = get_role("shop_manager");    echo '<pre>';    print_r($MY_other_role->capabilities);    echo '</pre>';  }}

This will display the capabilities of user roles on the wp-dashboard, you could also add something like if current_user_can('administrator') if you need to
