Getting Correct Product Link Within WooCommerce Loop When Using Twig And Timber

I have customised some of the WooCommerce templates and I am using the Twig templating system as well as Timber.

On the category pages I have just noticed that the product images all link correctly to the respective products, but the title below them all link to the first product on the page.

The difference between the two is the correct linking section with the photo is customised, and the incorrect linking title is generated via WooCommerce hooks.

Here are my respective files:

archive-product.php

defined( 'ABSPATH' ) || exit;

$context            = Timber::get_context();
$context['shop-sidebar'] = Timber::get_widgets( 'shop-sidebar' );

$posts = Timber::get_posts();
$context['products'] = $posts;

$context['search_str'] = (get_search_query()) ? get_search_query() : '';

if ( is_product_category() ) {
    $queried_object = get_queried_object();
    $term_id = $queried_object->term_id;
    $context['category'] = get_term( $term_id, 'product_cat' );
    $context['title'] = single_term_title( '', false );
} elseif (is_shop()) {

    $shop_id = get_option( 'woocommerce_shop_page_id' );
    $post = new TimberPost($shop_id);

    $alt_title = (!empty($post->get_field('alt_page_title')['title'])) ? $post->get_field('alt_page_title')['title'] : '';
    $context['title'] = ($alt_title) ? $alt_title : $post->post_title;

}

Timber::render( 'views/woo/archive.twig', $context );

views/woo/archive.twig

    {{ fn('timber_set_product', post) }}

    {% set title = (post.title) ? post.title : fn('the_title') %}

    <div class="photo {% if not post.thumbnail %}placeholder{% endif %}">
        <a href="{{ post.link }}" class="link">
            {% if post.thumbnail %}
                <img src="{{ post.thumbnail.src|resize(600)|e('esc_url') }}" class="img-responsive" alt="{{ fn('esc_attr', title) }}" />
            {% else %}
                <img src="{{ fn('wc_placeholder_img_src') }}" class="img-responsive" alt="Awaiting product image" />
            {% endif %}
        </a>
    </div>

    <div class="details">

        <h3 class="entry-title">

            {% do action('woocommerce_before_shop_loop_item') %}
            {% do action('woocommerce_before_shop_loop_item_title') %}
                {{ title|e2 }}
            {% do action( 'woocommerce_after_shop_loop_item_title' ) %}
            {% do action( 'woocommerce_after_shop_loop_item' ) %}

        </h3>

    </div>

</article>

The problem area is this bit:

<h3 class="entry-title">

    {% do action('woocommerce_before_shop_loop_item') %}
    {% do action('woocommerce_before_shop_loop_item_title') %}
        {{ title|e2 }}
    {% do action( 'woocommerce_after_shop_loop_item_title' ) %}
    {% do action( 'woocommerce_after_shop_loop_item' ) %}

</h3>

From what I can make out I am able to modify the anchor tag with this:

remove_action( 'woocommerce_before_shop_loop_item', 'woocommerce_template_loop_product_link_open', 10 );
add_action( 'woocommerce_before_shop_loop_item', 'myprefix_woocommerce_template_loop_product_link_open', 10 );

function myprefix_woocommerce_template_loop_product_link_open() {
    echo '<a href="https://www.google.com.au/">';
}

I am just not sure where the best place to put this code is and how to pass the correct permalink to it.

Answer

The permalink is accessible via the global product variable, as defined in your partial through {{ fn('timber_set_product', post) }}

Place the code in your functions.php.

remove_action( 'woocommerce_before_shop_loop_item', 'woocommerce_template_loop_product_link_open', 10 );
add_action( 'woocommerce_before_shop_loop_item', 'myprefix_woocommerce_template_loop_product_link_open', 10 );

function myprefix_woocommerce_template_loop_product_link_open() {
    global $product;
    $link = $product->get_permalink();
    echo '<a href="' . esc_url( $link ) . '" class="woocommerce-LoopProduct-link woocommerce-loop-product__link">';
}
