问题
(Warning: I'm not a programmer) Straight to the point.
I have a product catalogue http://adidassuperstar.cz, and I want images (thumbnails) point to the affiliate link - the same link as the link of a buy button under the image.
I googled everything, but none of the answers actually worked for me. However, I found something which helped me just half the way. When I insert this code to functions.php it makes this: Every link point to the affiliate link - I mean even a title of a product. I want only the image to have an affiliate link, not the title. The title should point to the product page on my site.
Here is the code:
// Do not include this if already open!
/**
* Code goes in theme functions.php.
*/
add_action('template_redirect', 'redirect_external_products');
function redirect_external_products() {
global $post;
if (is_singular( 'product' ) &&
! empty( $post ) &&
($product = wc_get_product($post)) &&
$product->is_type('external' )) {
wp_redirect( $product->get_product_url() );
exit;
}
}
I only need to specify the code to redirect only images (thumbnails). If you have a clue how to do that. Please let me know.

I use a WordPress theme: Avada
Products was imported with plugin: WP All import
If you need any more information, I will give it to you. Just ask :)
回答1:
WooCommerce uses a template for those images. They are product-thumbnails.php and 'product-image.php' files located in single-product folder in your WooCommerce templates folder.
For me these files are located in theme/woocommerce/single-product/ and "theme" is your theme (in this case Avada).
Based on what your theme does to WooCommerce templates (some themes rewrite them completely) you can just change some of those template files directly and add your links.
But the cleaner way would be to use actions that are used widely in WooCommerce and add your link to the images using them. The way I see it in an older version of Avada the themes modifies 'woocommerce_single_product_image_html' filter hook which shows the product main image.
If you share the files product-thumbnails.php and product-image.php with us we could find an easy solution.
I personally don't have access to your themes to see what exactly it does with images.
For now, you can put this code in your functions.php file and see how it turns out:
add_filter('woocommerce_single_product_image_html', 'change_product_image_link', 10, 2);
function change_product_image_link( $html, $product_id) {
$product = wc_get_product($product_id);
if (is_singular('product') &&
$product &&
$product->is_type('external')){
$attachment_count = count($product->get_gallery_attachment_ids());
$gallery = $attachment_count > 0 ? '[product-gallery]' : '';
$props = wc_get_product_attachment_props(get_post_thumbnail_id(), $post);
$image = get_the_post_thumbnail(
$post->ID,
apply_filters('single_product_large_thumbnail_size',
'shop_single'),
array(
'title' => $props['title'],
'alt' => $props['alt'],
));
return sprintf(
'<a href="%s" itemprop="image" class="woocommerce-main-image zoom" title="%s">%s</a>',
$product->get_product_url(),
esc_attr($props['caption']),
$image
);
}
else {
return $html;
}
}
To add external links to archive product images you can put this code in your functions.php:
remove_action('woocommerce_before_shop_loop_item', 'woocommerce_template_loop_product_link_open');
add_action('woocommerce_before_shop_loop_item_title', 'woocommerce_template_loop_product_link_open', 15);
add_action('woocommerce_before_shop_loop_item', 'woocommerce_add_aff_link_open', 10);
add_action('woocommerce_before_shop_loop_item_title', 'woocommerce_add_aff_link_close', 10);
function woocommerce_add_aff_link_open(){
$product = wc_get_product(get_the_ID());
if ($product->is_type('external'))
echo '<a href="' .
$product->get_product_url() .
'" class="woocommerce-LoopProductImage-link">';
}
function woocommerce_add_aff_link_close(){
$product = wc_get_product(get_the_ID());
if ($product->is_type('external'))
echo '</a>';
}
The second changes mixed with Avada's content-product.php file (I strongly suggest removing #2 edits from functions.php before using this edit):
<?php
/**
* The template for displaying product content within loops
*
* This template can be overridden by copying it to yourtheme/woocommerce/content-product.php.
*
* HOWEVER, on occasion WooCommerce will need to update template
files and you (the theme developer) will need to copy the new

as little as possible, but it does happen. When this occurs the
version of the template file will be bumped and the readme will
list any important changes.
