gist wc thank you for product

add_action( 'woocommerce_thankyou', 'ad_redirectcustom');
 
function ad_redirectcustom( $order_id ){
    $order = new WC_Order( $order_id );
    $items = $order->get_items();
     $product_id=223074;//id of your product
     $product_id2=223076;//  id of your product
      $url ='';// url for the redirection   after purchase your product 
    $url2='';
  foreach ( $items as $item ) {

   
 if (($order->status!='failed')&&(product_id==$item['product_id'])) {
        wp_redirect($url);
        exit;
    }
 else if (($order->status!='failed')&&($product_id2==$item['product_id'])) {
     wp_redirect($url2);
     exit; // 
    }
  }
}

BTw I dont understand: What is this? == $product_id2=223076;// must be change by id of you product
foreach ( $items as $item ) {
And what is this for?=== $url2='';

hi thank u for asking me ;) $prudct_id2 , is the id of your product that u want him redirect to the pages , for example $url='www.google.fr' , then out in the code
if (($order->status!='failed')&&(product_id==$item['product_id'])) {
wp_redirect($url);
exit;
}
so when user purchase that product he will redirect to the url , in my example $url='www.google.fr'

i 'll create youtube tutorial explain this
