I want to get woocommerce reviews by product id and display it in a template

Question

I want to fetch woocommerce product reviews by product id or anything else and want to display it in a template created by me.

Answer 1

In woocommerce/templates/single-product/tabs/tabs.php

If you run a print_r() on $tabs after it has been declared you'll see that a portion of the output is the following:

[reviews] => Array (
    [title] => Reviews (3)
    [priority] => 30
    [callback] => comments_template
)

This means that the callback is the function: comments_template().

Since this function doesn't accept a $post_id parameter, the would need to be called within the loop.

However, the function does accept a parameter of the template file to use, so to answer the OP's direct question of how to use a custom template file - you can use the function like so:

comments_template( string $file = '/comments.php', bool $separate_comments = false );
