Featured image for custom taxonomy

Hello !

I’ve created a custom taxonomy and created a custom image field for.
I would use it as a featured image (for a gridbuiler).
Any idea how to do it ?

Thanks !

That would dependent on what you are building with and would best be a question for the developers of that solution.

Terms in WP do not have “Featured Images”

Hello,
Thanks for your answer.
I do build on Woocommerce and it seems to me that the product category, witch is a wp taxonomy, has the featured image.
Anyway I’ve ask the gridbuilder support.
To be continued…

That is an image added by WC with code that shows them.

I wouldn’t know how to show a custom field for a term in whatever you are using to build with, you have not even relieved what it is you’re using.

As I said, how you show custom fields for a term would be determined by the tool you are using to build the page.

The only thing I can point you to is PHP code which is not what I thin you’re looking for.

Hi,

Sorry for that misunderstanding, I’m working on woocommerce and the plugin “WP Gridbuilder”.
And a php code is exactly what I’m looking for !

So far I’ve done this :

function save_acf_image_as_featured_in_taxonomy($term_id) {
// Assurez-vous de remplacer ‘nom_du_champ_image’ par le slug de votre champ ACF
$image_id = get_field(‘_thumbnail_id_marque’, ‘taxonomy_’ . $term_id);

if ($image_id) {
// Enregistrez l’ID de l’image dans les métadonnées de la taxonomie
update_term_meta($term_id, ‘featured_image_id’, $image_id);
}
}
add_action(‘edited_ma_taxonomie’, ‘save_acf_image_as_featured_in_taxonomy’);
add_action(‘create_ma_taxonomie’, ‘save_acf_image_as_featured_in_taxonomy’);

function set_custom_card_thumbnail_for_taxonomy($object) {
// Obtenez les paramètres du grid courant.
$grid = wpgb_get_grid_settings();

// Si cela ne correspond pas à l’ID du grid 6.
if (6 !== $grid->id) {
return $object;
}

// Si l’objet est une taxonomie (ajustez ‘ma_taxonomie’ pour votre taxonomie).
if (is_a($object, ‘WP_Term’) && ‘marque’ === $object->taxonomy) {
// Obtenez l’ID de l’image ACF pour la taxonomie.
$image_id = get_field(‘_thumbnail_id_marque’, ‘taxonomy_’ . $object->term_id);

// Si un ID d’image est trouvé, affectez-le.
if (!empty($image_id)) {
$object->post_thumbnail = $image_id;
}
}

return $object;
}
add_filter(‘wp_grid_builder/grid/the_object’, ‘set_custom_card_thumbnail_for_taxonomy’);

But it’s not working…
I was poiting out the product category miniatures of woocomerce because, without any dev, it just works fine with what I’m willing to do.

Thanks.

This document covers getting values from a term https://www.advancedcustomfields.com/resources/adding-fields-taxonomy-term/

You are doing that incorrectly

$image_id = get_field(‘_thumbnail_id_marque’, ‘term_’ . $term_id);

you can also call this function with the term object instead of "term_{$term_id}"

This document covers using an image field https://www.advancedcustomfields.com/resources/image/

How you use it depends on what you have set as a return value for the image field. But you can always get only the ID value regardless of the return setting by setting the 3rd parameter to false

$image_id = get_field(‘_thumbnail_id_marque’, ‘term_’ . $term_id, false);
