I have tried the code below, and tried to do as on the page here, but it doens't work...
https://www.advancedcustomfields.com/resources/adding-fields-taxonomy-term/
*The image return format is "Array".
function action_woocommerce_before_variations_form( ) {
$queried_object = get_queried_object();
$taxonomy = $queried_object->taxonomy;
$term_id = $queried_object->term_id;
$image = get_field('brand_logo', $taxonomy . '_' . $term_id);
echo '<img src="'.$image['url'].'" />';
};
// add the action
add_action( 'woocommerce_before_variations_form', 'action_woocommerce_before_variations_form', 10, 0 );

Answer 1

You can try like this:
<?php
$category_icon = get_woocommerce_term_meta( $cat->term_id, 'thumbnail_id', true );
$category-logo = wp_get_attachment_url( $category_icon );
?>

Answer 2

The woocommerce_before_variations_form is call on product page.
So if when you call get_queried_object() WordPress will return Product Object, not brand term.
So
Get brand(s) with your product id with get_the_terms function
Iterate on your brands and get image with get_field function
(optional) get brand link
Display your image
<?php
function prefix_add_brand_before_variations_form() {
// First get brand(s) with your product id.
$brands = get_the_terms(get_the_id(), 'brand');
// get_the_terms return false or an array, so
if(!$brands) {
return;
}
foreach ($brands as $brand) {
$image = get_field('brand_logo', $brand);
$brand_url = get_term_link($brand);
if (is_array($image)) : ?>
<a href="<?php echo $brand_url ?>">
<img src="<?php echo $image['url']; ?>" />
</a>
<?php
endif;
}
}
add_action('woocommerce_before_variations_form', 'prefix_add_brand_before_variations_form', 10, 0);
