Getting the product price of a WooCommerce product with Timber, Twig and ACF outside of WooCommerce

Question

I'm building a custom product loop outside of WooCommerce and I have setup a repeater loop within ACF where they can select the product they want to display and it returns the product's object; however this doesn't quite seem to match the same object you would get back with using the WC function get_product, as in, the price details are returned like this:

[_regular_price] => 14.99
[_sale_price] => 
[_price] => 14.99

These fields aren't accessible like many other fields as they start with an underscore.

The above data comes from a loop, such as:

{% for product in post.get_field('showcase_products') %}
    ...
{% endfor %}

I also tried doing product.get_price in Twig but it doesn't work.

I was then able to try doing the below:

{% set price = fn('wc_get_product', product.id) %}

Then I was able to use any of the below:

{{ fn('print_r', price.price) }}
{{ fn('print_r', price.get_price) }}
{{ fn('print_r', price.get_price_html) }}

Is there a way to be able to get the above data without the extra call to the WC function wc_get_product within each loop?

Answer 1

however this doesn't quite seem to match the same object you would get back with using the WC function get_product

This is because the ACF repeater field is set to return WP_Post data in an array, even for the "product" post type. ACF doesn't convert each post in the repeater array to a Woocommerce product for you, so you have to do it manually on each loop as you have {% set price = fn('wc_get_product', product.id) %}

Even Timber uses the wc_get_product function in their docs here https://timber.github.io/docs/guides/woocommerce/

I don't think there's anything particularly wrong or resource heavy in converting each post in the array with that function.
