Until the new system is out can someone help me add brands taxonomy terms to new product in REST?

[rudtek]

I created my own custom brand (product_brands) as a taxonomy and added it to the REST API using this code:

add_filter( 'woocommerce_rest_prepare_product_object', 'ul_rest_api_prepare_brands_tax', 10, 3 );
function ul_rest_api_prepare_brands_tax( $response, $object, $request ) {
    $product_id = $object->get_id();
    if ( empty( $response->data[ 'product_brands' ] ) ) {
        $terms = [];
        foreach ( wp_get_post_terms( $product_id, 'product_brands' ) as $term ) {
            $terms[] = [
                'id'   => $term->term_id,
                'name' => $term->name,
                'slug' => $term->slug,
            ];
        }
        $response->data[ 'product_brands' ] = $terms;
    }
    return $response;
}

I can see brands attached when I use a GET for products, and with only this code I could not PUT OR POST a product with this brand.

So I added this code:

function ul_prepare_insert_product( $product, $request ) {
    if ( isset( $request['product_brands'] ) ) {
        wp_set_post_terms($request['id'], $request['product_brands'], 'product_brands', false);
    }
    return $product;
}
add_filter( 'woocommerce_rest_pre_insert_product_object', 'ul_prepare_insert_product', 10, 2 );

This works if I PUT an array to the body of an existing product endpoint to allow me to add brand terms. My array is just product_brands[61] (which is the ID of one of my existing brand terms.) I found that I can use an ID if I use wp_set_post_terms (not wp_set_object_terms). set_object_terms will only allow me to use the brand slug.

However, neither option works if I try to POST a NEW product with an existing brand term. Nothing gets set into the brand for the product.

I've looked high and low for documentation on this but came up short. Here's some further notes/assumptions and questions.

Some sites said to use woocommerce_rest_pre_insert_product and some said woocommerce_rest_pre_insert_product_object. My understanding is that using object is the new way to do it.

I didn't get some of the parameters either. Sometimes it was $object and sometimes it was $product. Either case seems to work but I think it may have to do with whether I used the filter woocommerce_rest_pre_insert_product_object or woocommerce_rest_pre_insert_post_object. I'm not sure.

thank you. I saw this post too, which may or may not help.

woocommerce_rest_pre_insert_product_object Filter: This filter is correct for both POST and PUT requests when dealing with product objects.

add_filter('woocommerce_rest_pre_insert_product_object', 'ul_prepare_insert_product', 10, 2);
function ul_prepare_insert_product($product, $request) {
    if (isset($request['product_brands'])) {
        wp_set_object_terms($product->get_id(), $request['product_brands'], 'product_brands');
    }
    return $product;
}

please use this code

Thanks for helping me on this. That's the same code that I had but using wp_set_object instead of wp_set_post This code does work when I use a PUT and the body has the array product_brands[61] it does not work for POST though at all. my results show an empty array for product_brands.

my array that I'm sending when I PUT is:

{
	"name": "Beaut2",
	"type": "simple",
	"regular_price": "21.99",
	"description": "Pellentesque habitant morbi tristique senectus et netus et malesuada fames ac turpis egestas. Vestibulum tortor quam, feugiat vitae, ultricies eget, tempor sit amet, ante. Donec eu libero sit amet quam egestas semper. Aenean ultricies mi vitae est. Mauris placerat eleifend leo.",
	"short_description": "Pellentesque habitant morbi tristique senectus et netus et malesuada fames ac turpis egestas.",
	"categories": [
	{
		"id": 9
	},
	{
		"id": 14
	}],
	"product_brands": [
		62
    ]
}
