I want to add some extra images to the product gallery. Based on a meta field from a different post. The images should only add to the gallery in the frontend. Not to the image gallery of the product itself.
EDIT: @mujuonly was right. I could use woocommerce_product_thumbnails
and so I tried the following code and everything works fine:
<?php
add_action( 'woocommerce_product_thumbnails', 'custom_product_add_thumbnails', 100, 0 );
function custom_product_add_thumbnails(){
$extra_gallery = get_field( 'some_field' );
if( $extra_gallery ): ?>
<?php foreach ( $extra_gallery as $image_id ): ?>
<div class="woocommerce-product-gallery__image">
<?php echo wp_get_attachment_image( $image_id, 'woocommerce_single', false, array( "class" => "" ) ); ?>
</div>
<?php endforeach; ?>
<?php endif;
endif;
}
With 100
in the action the images are shown at the end of the gallery:
add_action( 'woocommerce_product_thumbnails', 'custom_product_add_thumbnails', 100, 0 );
add_action( 'woocommerce_product_thumbnails', 'custom_product_add_thumbnails', 100, 0 );
function custom_product_add_thumbnails(){
// Echo images here
}
