How Do I Update My WooCommerce Cart Meta Data?

If you’ve ever needed to update your WooCommerce cart meta data, you know it can be a bit tricky. Here’s a quick guide on how to do it.

1. First, you’ll need to add the following code to your functions.php file:

function my_custom_cart_data( $cart ) {
  if ( is_admin() && ! defined( 'DOING_AJAX' ) )
return;
   foreach ( $cart->get_cart() as $key => $item ) {
     $item['my_custom_data'] = 'Hello World';
   }
   return $item;
}
add_filter( 'woocommerce_get_item_data', 'my_custom_cart_data', 10, 2 );

2. Next, you’ll need to add the following code to your cart-totals.php file:

foreach ( $cart->get_cart() as $key => $item ) {
  $item['my_custom_data'] = 'Hello World';
}
  return $item;
}

3. Finally, you’ll need to add the following code to your checkout.php file:

foreach ( $cart->get_cart() as $key => $item ) {
  $item['my_custom_data'] = 'Hello World';
}
  return $item;
}
  $checkout = new WC_Checkout();
  $checkout->process();
