Woocommerce: Which Hook to Replace Deprecated "Woocommerce_Add_Order_Item_Meta"

Woocommerce: Which hook to replace deprecated woocommerce_add_order_item_meta

If you look at wc-deprecated-functions.php you will see

/**
 * @deprecated
 */
function woocommerce_add_order_item_meta( $item_id, $meta_key, $meta_value, $unique = false ) {
    return wc_add_order_item_meta( $item_id, $meta_key, $meta_value, $unique );
}

Basically, the function was renamed to wc_add_order_item_meta(), so if you need the function then use that. The action hook was not renamed and remains in class-wc-checkout.php as:

// Allow plugins to add order item meta
do_action( 'woocommerce_add_order_item_meta', $item_id, $values, $cart_item_key );

Replace woocommerce_add_order_item_meta hook in Woocommerce 3.4

Updated

Since Woocommerce version 3, woocommerce_checkout_create_order_line_item action hook now replace outdated woocommerce_add_order_item_meta hook in a much better way using the new introduced CRUD getters and setters methods:

// Save custom data to order item meta data
add_action( 'woocommerce_checkout_create_order_line_item', 'tshirt_order_meta_handler', 20, 4 );
function tshirt_order_meta_handler( $item, $cart_item_key, $values, $order ) {
    $custom_designer = WC()->session->get( $cart_item_key.'_designer' );
    if( ! empty($custom_designer) ) {
        $item->update_meta_data( 'custom_designer', $custom_designer );
    }
}

Code goes in function.php file of your active child theme (or active theme). It should works.

Replace woocommerce_add_order_item_meta hook in Woocommerce 3+

You need to change more than just the hook… The hooked function arguments are wrong in your code and the way to updated data has changed too. Try the following:

add_action( 'woocommerce_checkout_create_order_line_item', 'add_business_days', 10, 4 );
function add_business_days( $order_item, $cart_item_key, $cart_item, $order ){

    $now     = current_time( 'mysql' );
    $add     = $cart_item['data']->get_meta( 'dp_kargolanma_suresi' );
    $d       = new DateTime( $now );
    $t       = $d->getTimestamp();
    $oneDay  = 86400;
    $nextDay = date('w', ($t + $oneDay));


    // loop for X days
    for( $i = 0; $i < $add; $i++ ) {
        // if it's Saturday or Sunday get $i-1
        if($nextDay == 0 || $nextDay == 6) {
            $i--;
        }
        // modify timestamp, add 1 day
        $t = $t + $oneDay;
    }
    $d->setTimestamp($t);

    $teslim_tarihi = $d->format( 'd-m-Y' ). "\n"; 
    $desiveyakg    = ( $cart_item['quantity'] * $cart_item['data']->get_weight() );
    $kargosinifi   = $cart_item['data']->get_shipping_class();

    $order_item->update_meta_data( 'En Gec Kargolanma Tarihi', $teslim_tarihi );
    $order_item->update_meta_data( '_desi_kg', $desiveyakg );
    $order_item->update_meta_data( '_alici_onay_durumu', 'Onay Bekliyor' );

    if($cart_item['quantity'] >= 100) {
        $order_item->update_meta_data( '_kargo_sinifi', 'ucretsiz-kargo' );
    } else {
        $order_item->update_meta_data( '_kargo_sinifi', $kargosinifi );
    }
}

It should work…

Problem with woocommerce_add_order_item_meta

Hook woocommerce_add_order_item_meta is replaced by woocommerce_checkout_create_order_line_item, so with your code (assuming that the cart object contains your custom cart item data):

add_action('woocommerce_checkout_create_order_line_item', 'save_custom_order_item_meta_data', 10, 4 );
function save_custom_order_item_meta_data( $item, $cart_item_key, $values, $order ) {
    if( isset( $values['custom_data']['label'] ) && isset( $values['custom_data']['value'] ) ) {
       $item->update_meta_data( $values['custom_data']['label'], $values['custom_data']['value'] );
    }
}

Code goes in function.php file of your active child theme (or active theme). It should works.

How to add new meta item for each order item in WooCommerce?

Try this instead,

add_action( 'woocommerce_checkout_create_order_line_item', 'add_my_meta_to_line_item', 10, 4 );

function add_my_meta_to_line_item( $item, $cart_item_key, $values, $order) {
  if ($_POST['design']) $item->add_meta_data( 'design', esc_attr($_POST['design'], true ));
}

Trying to save order item meta data with woocommerce_new_order_item hook

Since Woocommerce 3 and the new CRUD setters and getters methods, use this instead:

add_action( 'woocommerce_checkout_create_order_line_item', 'add_booking_order_line_item', 20, 4 );
function add_booking_order_line_item( $item, $cart_item_key, $values, $order ) {
    // Get cart item custom data and update order item meta
    if( isset( $values['adults_qty'] ) ){
        if( ! empty( $values['adults_qty'] ) )
            $item->update_meta_data( 'Adults', $values['adults_qty'] );
    }
}

Woocommerce which hook to use for order status changes

"I need to catch every time an order status changes from wc_on_hold to wc_completed"

You would need to change your hook to woocommerce_order_status_changed.

"I couldn't get on Chrome's Console that echo giving me the order price"

You can't use javascript and console.log in this hook. You would need to either use the die function or the error_log function to log it to your debug.log file.

Using die function

add_action('woocommerce_order_status_changed', 'so_status_completed', 10, 3);

function so_status_completed($order_id, $old_status, $new_status)
{

    $order = wc_get_order($order_id);

    //$order_total = $order->get_formatted_order_total();
    $order_total = $order->get_total();

    die($order_total);
}

---

Using error_log function

dd_action('woocommerce_order_status_changed', 'so_status_completed', 10, 3);

function so_status_completed($order_id, $old_status, $new_status)
{

    $order = wc_get_order($order_id);

    //$order_total = $order->get_formatted_order_total();
    $order_total = $order->get_total();

    error_log(print_r('order total: ' . $order_total, true));
}

---

Second question

"since I am just here, I want to ask you if $order-get_total() is the right one to retrieve order amount without fee applied?"

You might want to take a look at the $order->get_subtotal() for the totals before shipping, coupons and taxes:

woocommerce_add_order_item_meta hook sending only one argument; three expected

Shame on me!I had not found necessary to add the last two arguments of the add_action() function. So the default number of argument being one, only one was passed to my callback.

so the right code for the add_action() function is:

add_action('woocommerce_add_order_item_meta', array($this, 'charlie_ajoute_un_order_item_meta'), 10, 3);

Hope it may help someone.

Which Woocommerce hook when order is purchased for an external delivery service

Instead, you could try to use the following hooked function, that will work for defined order statuses only once, after the delivery data is processed.

add_action( 'woocommerce_order_status_changed', 'delivery_information_process', 20, 4 );
function delivery_information_process( $order_id, $old_status, $new_status, $order ){
    // Define the order statuses to check
    $statuses_to_check = array( 'on-hold', 'processing' );

    // Only  "On hold" order status and "Free Shipping" Shipping Method
    if ( $order->get_meta( '_delivery_check', true ) && in_array( $new_status, $statuses_to_check ) )
    {
        // Getting all WC_emails objects
        foreach($order->get_items() as $item_id => $item ){
            $product = $item->get_product();
            $sku     = $product->get_sku();
        }

        ## ==> Process delivery data step

        // Once delivery information is send or processed ==> update '_delivery_check' to avoid repetitions
        $order->update_meta_data( '_delivery_check', true );
    }
}

Code goes in function.php file of your active child theme (or active theme). Tested and works.
