Hi @eolis
I think you can loop through the product_urls repeater and then check the keys like this:
$productURLsRow = get_field('product_urls');
print_r($productURLsRow);
foreach($productURLsRow as $productURLs){
foreach($productURLs as $key => $productURL){
if(!empty($productURL)){
if($key == 'product_urls_us'){
echo "us";
} elseif ($key == 'product_urls_ca'){
echo "ca";
}
}
}
}
I hope this helps.
