Thank you John
That worked!
One comma was missing
$images = implode(',' , $images);
I’ll paste my functions.php here if anyone in future is doing the same:
Transferring product data (featured image, images gallery, price) from ACF to WooCommerce
function acf_set_featured_image( $value, $post_id, $field ){
if($value != ''){
//Add the value which is the image ID to the _thumbnail_id meta data for the current post
add_post_meta($post_id, '_thumbnail_id', $value);
}
return $value;
}
add_filter('acf/update_value/name=my_featured_image', 'acf_set_featured_image', 10, 3);
function acf_set_current_price( $value, $post_id, $field ){
if($value != '')
update_post_meta($post_id, '_price', $value);
return $value;
}
function acf_set_regular_price( $value, $post_id, $field ){
if($value != '')
update_post_meta($post_id, '_regular_price', $value);
return $value;
}
add_filter('acf/update_value/name=my_price', 'acf_set_regular_price', 10, 3);
function my_acf_save_post($post_id) {
$repeater = 'other_images';
$subfield = 'image';
// using get_post_meta because that way we're sure to get the image ID
$count = intval(get_post_meta($post_id, $repeater, true));
$images = array();
for ($i=0; $i<$count; $i++) {
$field = $repeater.'_'.$i.'_'.$subfield;
$images[] = intval(get_post_meta($post_id, $field, true));
}
if (count($images)) {
$images = implode(',', $images); // convert to comma separated list
} else {
$images = '';
}
update_post_meta($post_id, '_product_image_gallery', $images);
}
add_action('acf/save_post', 'my_acf_save_post', 20); // priority of 20 so it runs after ACF
