WooCommerce Url rewrites – SEO

I’ve got the same problem described in this post:
[WordPress URL rewrite for WooCommerce attributes, except that I need to filter by attribute not only inside a category.
Unfortunately, I cannot post a comment before reaching a higher reputation, so I’m creating a new question.

I defined a manufacturer attribute and if I want to browse all products from a certain manufacturer, I can use a url like www.example.com/shop/?filter_manufacturer=230, where 230 is the attribute ID.
I tried adding a endpoint, like suggested in the post linked above above, but I cannot get the rewrites working; for example, if I try to open www.example.com/shop/manufacturer/manufacturer_name I get a 404 error.

It’s not clear to me if I should change anything in the permalink settings in WordPress and, if yes, how.
I’ve always flushed the rewrite rules after every edit, BTW.

    The missing link between your question regarding WooCommerce attributes and the linked answer is that product attributes are merely taxonomies with a ‘pa_’ appended to their name.

    In your case the taxonomy is called “pa_manufacturer”. WooCommerce sets these up by default to have no query var attached.

    So in lieu of filtering query_vars we are going to target when WooCommerce registers that particular taxonomy. I’ve also modified to remove anonymous functions.

    In my example I am using “color”, so adjust to “manufacturer”. I was able to then go to a URL of http://example.com/shop/color/black and see all the black products. Note that this doesn’t get you a term archive where /shop/color will list all the colors. That is a different question and a lot more work.

    I didn’t test the activation part, so if you get 404s after activating you can just delete the whole activation function and simply go to Settings>Permalinks and save the permalinks again.

    /**

function so_28460538_add_rewrite_endpoint(){
    add_rewrite_endpoint( 'color', EP_ALL );
}
add_action( 'init', 'so_28460538_add_rewrite_endpoint' );


function so_28460538_attribute_args( $args ){
    $args['query_var'] = 'color';
    return $args;
}
add_filter( 'woocommerce_taxonomy_args_pa_color', 'so_28460538_attribute_args' ); 


/**
 * Refresh permalinks on plugin activation
 * Source: http://wordpress.stackexchange.com/a/108517/12615 
 */
function WCM_Setup_Demo_on_activation(){
    if ( ! current_user_can( 'activate_plugins' ) )
        return;

    $plugin = isset( $_REQUEST['plugin'] ) ? $_REQUEST['plugin'] : '';
    check_admin_referer( "activate-plugin_{$plugin}" );

    add_rewrite_endpoint( 'color', EP_ALL ); #source: http://wordpress.stackexchange.com/a/118694/12615
    flush_rewrite_rules();
}
register_activation_hook(   __FILE__, 'WCM_Setup_Demo_on_activation' );

    EDIT

    Adding some screenshots of my settings in case it will help determine why you are getting 404s:

    Here are my permalinks settings:

    permalink settings

    and here is the WooCommerce setting for determining the product archive page:

    WC shop settings

    And finally, here is the result of visting:
    http://local.wordpress.dev/shop/color/black/

    Where shop is the pretty permalink for the product archive page set above. All items have a ‘black’ color attribute.

    I had a similar problem and was able to solve it like this:

    function add_model_taxonomy_args($args) {
    $args['query_var'] = 'filter_model';
    return $args;
}
add_filter('woocommerce_taxonomy_args_pa_model', 'add_model_taxonomy_args' ); 

function custom_rewrite_rules() {
	add_rewrite_tag('%filter_model%', '([a-zA-Z0-9-]+)');
	add_rewrite_rule('^c/phone-cases/(.+?)/?$', 'index.php?product_cat=phone-cases&filter_model=$matches[1]', 'top');
}
add_action('init', 'custom_rewrite_rules', 10, 2);

    Sample Url: c/phone-cases/iphone-8-plus/

    Resulting Rewrite: index.php?product_cat=phone-cases&filter_model=iphone-8-plus
