How to Avoid Duplicate Terms in WordPress Taxonomy

[Vasco]

Hello,

I’m creating WordPress tags based on the content of an article. The issue is that when ChatGPT creates the same tag based on another article, the module “Create a Tag” returns the error: [400] A term with the name provided already exists in this taxonomy. (error code: term_exists)

Is there a way to avoid this? For example, I could search if a value already exists and, if so, return that value without creating it (to avoid the error), and continue the scenario flow. Later in the flow, I’ll need to map those tags (both the new ones and those that already exist).

Thanks!

Welcome to the Make community!

You’ll need to split the categories by comma-space so that it becomes an array.

Then, use an iterator on the array so that you can process each category at a time.

Create new category using the name.

Then, if category exists, there will be an error. Handle the error by searching for the category, and resuming with the existing category ID.

Then, aggregate the category IDs into an array using the Array Aggregator.

You can then insert the array of category IDs into the tag/category field.

Similarly, this works the same way for the Wordpress Tags field.

Hope this helps! Let me know if there are any further questions or issues.

@samliew, thanks for the reply, although it’s exactly the same reply I’ve read on many other topics. However, some questions still arise.

What should I put in the Name field of Create a Tag? I have 10 tags but the iterator only allows me to map the first one.

And what should I put in the Search field of Search Tags?

Creating all tags separately
I already have my ten tags comma-space separated and iterated, and WordPress can create them separately with no issues, although I used steps different from your example (because I don’t know how to create ten tags using only one module). I had to use “Set multiple variables” after the iterator to be able to map each tag individually on ten “Create a Tag” modules (that’s because the Iterator only allows me to map the first tag, although it outputs a bundle for each tag). Maybe there’s a better way to do that…

In the “Create a Post” module, you insert map(Array[];id) in the Tag field—just to be clear, will it assign ALL tag IDs to the post?

So, resuming:

1. I’m still unable to create all tags using only one Create a Tag module, which seems to be the most efficient way to do it.
2. How to customize Search Tags and Resume to avoid duplicate tags, while still retrieving all tag ids (even the duplicate ones).
