Hello I was using woocommerce_add_order_item_meta to add some additional information for order item. After woocommerce update I got error on ordar pay page. I researched that why it happens. I found this article. and I understood why I'm getting error. I changed action hook name but still get errors. What should I do ?
function addBizDays($item_id, $cart_item ,$start, $add){
$start =current_time( 'mysql' );
$add = get_post_meta( $cart_item[ 'product_id' ], 'dp_kargolanma_suresi', true );
$d = new DateTime($start );
$t = $d->getTimestamp();
// loop for X days
for($i=0; $i<$add; $i++){
// add 1 day to timestamp
$addDay = 86400;
// get what day it is next day
$nextDay = date('w', ($t+$addDay));
// if it's Saturday or Sunday get $i-1
if($nextDay == 0 || $nextDay == 6) {
$i--;
}
// modify timestamp, add 1 day
$t = $t+$addDay;
}
$d->setTimestamp($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();
wc_update_order_item_meta( $item_id, 'En Gec Kargolanma Tarihi', $teslim_tarihi );
wc_update_order_item_meta( $item_id, '_desi_kg', $desiveyakg );
wc_update_order_item_meta( $item_id, '_alici_onay_durumu', 'Onay Bekliyor' );
if($cart_item['quantity'] >= 100)
{
wc_update_order_item_meta( $item_id, '_kargo_sinifi', 'ucretsiz-kargo' );
}
else{
wc_update_order_item_meta( $item_id, '_kargo_sinifi', $kargosinifi );
}
}
add_action( 'woocommerce_checkout_create_order_line_item', 'addBizDays', 10, 5 );

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…
