How to send specific line item data to third party script - php

Question

I'm trying to send price, name and id of each item in the order, plus an extra static value to a single js variable formatted in this way,
items = eventID::price::name|eventID::price::name|eventID::price::name
I was trying to do it this way, but I'm getting an error on the last line which I mean to add a pipe if there is more than one product.
$line_items = $order->get_items();
//loop over line items
$wgItemCount = $order->get_item_count();
$wgItems = array();
foreach ( $line_items as $item ) {
$wgItem = array();
$wgItem ['eventId'] = '777777';
$wgItem ['eventId'] .= '::';
$wgItem ['price'] = $order->get_line_total( $item, true, true );
$wgItem ['price'] .= '::';
$wgItem ['name'] = $item->get_name();
if ($wgItemCount > 1) { //add divider if more than one item
wgItem .= '|';
}
$wgItems[] = $wgItem;
}
That hasn't worked so far, so I thought maybe I should create a custom object that contains the variables instead:
wgProduct = "77777", $order->get_line_total( $item, true, true ), $item->get_name();
and then call the items in a list later like
echo print ("|", wgProduct)
I had also tried using JSON to encode the data but the third party told me that is not going to work for their needs.
Edit: Code is now doing everything I need it to, but it's only pulling one item from the list instead of a string of all of them.
Here's what it looks like now based on the help I got here:
add_action( 'woocommerce_thankyou','wg_tracking' );
function wg_tracking( $order_id ) {
$order = wc_get_order( $order_id );
$shipping_total = $order->get_shipping_total();
$order_total = $order->get_total();
$currency = $order->get_currency();
$coupons = $order->get_coupon_codes();
$items = $order->get_items();
$total_exc_shipping = $order_total - $shipping_total;
$order_discount = $order->discount_total;
foreach( $coupons as $coupon ){
$coupon_post_object = get_page_by_title($coupon, OBJECT, 'shop_coupon');
$coupon_id = $coupon_post_object->ID;
$coupon = new WC_Coupon($coupon_id);
}
$wgItems = array();
foreach ( $items as $item ) {
$line = '';
$line .= '77777';
$line.= '::' . $order->get_line_total( $item, true, true );
$line .= '::' . $item->get_name();
$line .= '::' . $item->get_id();
}
$wgItems[] = $line;
$itemsList = implode('|', $wgItems);
?>
<script>
(function(w,e,b,g,a,i,n,s){w['ITCVROBJ']=a;w[a]=w[a]||function(){
(w[a].q=w[a].q||[]).push(arguments)},w[a].l=1*new Date();i=e.createElement(b),
n=e.getElementsByTagName(b)[0];i.async=1;i.src=g;n.parentNode.insertBefore(i,n)

ITCVRQ('set', 'trk.programId', 88888);
ITCVRQ('set', 'cvr', {

I think this all can be simplified to just use array's implode() method.
Below are what I would do in your situation:
$wgItems = array();
foreach ( $line_items as $item ) {
$line = '';
$line .= '777777';
$line .= '::' . $order->get_line_total( $item, true, true );
$line .= '::' . $item->get_name();
$wgItems[] = $line;
}
$items = implode('|', $wgItems);
