This guide shows the hooks available to you who want to modify the default Datalayer for WooCommerce behavior.
It is important to be clear that we will not give complete examples of the possibilities, but only an idea of what is possible to do.
We believe that in most cases you don’t need to use the hooks, be careful when using them, and only use them if you really need them.

Remove a specify product in the category/product pages:

function my_custom_hook_datalayer_impressions_verify_product( $products ) {
	foreach ( $products as $key => $product ) {
		if($product->get_id() === 225){
			unset( $products[$key] );
		}
    }
	$products = array_values($products);
    return $products;
}
add_filter( 'datalayer_before_impressions_loop_items', 'my_custom_hook_datalayer_impressions_verify_product' );

Add a specify product in the category/product page:

function my_custom_hook_datalayer_impressions_add_product( $products ) {
	$products[] = $new_product = new WC_Product( 175 ); // Create a new product object
	return $products;
}
add_filter( 'datalayer_before_impressions_loop_items', 'my_custom_hook_datalayer_impressions_add_product' );

Check if the product is part of a WooCommerce package and remove it in the checkout pages:

function my_custom_hook_datalayer_checkout_verify_product( $products ) {
	foreach ( $products as $key => $product ) {
        // Check if the product is part of a WooCommerce package
        if ( ! empty( wc_pb_get_bundled_product_map( $product['product'] ) ) ) {
            // If it's part of a package, remove the product from the array
            unset( $products[$key] );
        }
    }
    return $products;
}
add_filter( 'datalayer_before_checkout_loop_items', 'my_custom_hook_datalayer_checkout_verify_product' );

Add a specify product in the category/product in the checkout pages:

function my_custom_hook_datalayer_checkout_add_product( $products ) {
	$quantity = 1;
	$variation_id = null;
	$products[] = array(
		'quantity' => $quantity,
		'product'  => $new_product = new WC_Product( 225 ), // Create a new product object
		'variation_id' => $variation_id
	);
	return $products;
 }
add_filter( 'datalayer_before_checkout_loop_items', 'my_custom_hook_datalayer_checkout_add_product' );

Check if the product is part of a WooCommerce package and remove it in the thankyou page:

function my_custom_hook_datalayer_order_verify_product( $products ) {
	foreach ( $products->get_items() as $key => $item ) {
        // Check if the item is part of a WooCommerce package
        if ( wc_pb_is_bundled_order_item( $item ) ) {
            // If it's part of a package, remove the item from the array
            $products->remove_item( $key );
        }
    }
    return $products;
}
add_filter( 'datalayer_before_order_loop_items', 'my_custom_hook_datalayer_order_verify_product' );

Add a specify product in the thankyou page:

function my_custom_hook_datalayer_order_add_product( $products ) {
	$new_product_id = 225; // ID of the product you want to add
	$new_product = wc_get_product( $new_product_id );
	if ( $new_product ) {
		$order_item = new WC_Order_Item_Product();
		$order_item->set_props(
			array(
				'product' => $new_product,
				'quantity' => 1
			)
		);
		$products->add_item( $order_item );
	}
    return $products;
}
add_filter( 'datalayer_before_order_loop_items', 'my_custom_hook_datalayer_order_add_product' );

Get a product specific attribute (pa_color) and add it as a new parameter (item_category2) in the datalayer on category/product pages.

function my_custom_hook_datalayer_impressions_verify_product( $datalayer, $product ) {
	$attribute  = $product->get_attribute('pa_color');
	if($attribute){
		$datalayer['item_category2'] = $attribute;
	}
    return $datalayer;
}
add_filter( 'datalayer_during_impressions_loop_items_before_push', 'my_custom_hook_datalayer_impressions_verify_product', 10, 2 );

Get a product specific attribute (pa_color) and add it as a new parameter (item_category2) in the datalayer on checkout pages.

function my_custom_hook_datalayer_checkout_verify_product( $datalayer, $product ) {
	$attribute  = $product->get_attribute('pa_color');
	if($attribute){
		$datalayer['item_category2'] = $attribute;
	}
    return $datalayer;
}
add_filter( 'datalayer_during_checkout_loop_items_before_push', 'my_custom_hook_datalayer_checkout_verify_product', 10, 2 );

Get a product specific attribute (pa_color) and add it as a new parameter (item_category2) in the datalayer on thankyou page.

function my_custom_hook_datalayer_order_verify_product( $datalayer, $product ) {
	$product_attributes_data = wc_get_product( $product->get_product_id() );
	$attribute  = $product_attributes_data->get_attribute('pa_color');
	if($attribute){
		$datalayer['item_category2'] = $attribute;
	}
    return $datalayer;
}
add_filter( 'datalayer_during_order_loop_items_before_push', 'my_custom_hook_datalayer_order_verify_product', 10, 2 );

Remove the + sign from the phone number.

function my_custom_hook_datalayer_before_user_phone_push( $user_phone ){
	$user_phone = str_replace('+','',$user_phone);
	return $user_phone;
}
add_filter( 'datalayer_before_user_phone_push', 'my_custom_hook_datalayer_before_user_phone_push', 10, 1 );
