You're trying to access your array with $array->value, but the correct syntax would be $array['value']
I would loop through the meta data and check each key to see if is equals "tracking number" then echo out or do whatever you want with the result!
<?php
$test =array (
'id' => 448,
'parent_id' => 0,
'status' => 'completed',
'currency' => 'GBP',
'version' => '3.7.1',
'prices_include_tax' => true,
'meta_data' =>
array (
0 =>
array (
'id' => 8041,
'key' => 'is_vat_exempt',
'value' => 'no',
),
1 =>
array (
'id' => 8043,
'key' => '_wpam_id',
'value' => '4',
),
2 =>
array (
'id' => 8046,
'key' => '_woo_pp_txnData',
'value' =>
array (
'refundable_txns' =>
array (
0 =>
array (
'txnID' => '1U998392V9620752U',
'amount' => '5.95',
'refunded_amount' => 0,
'status' => 'Completed',
),
),
'txn_type' => 'sale',
),
),
3 =>
array (
'id' => 8056,
'key' => 'Payer PayPal address',
'value' => 'anthony#befive.co.uk',
),
4 =>
array (
'id' => 8057,
'key' => 'Payer first name',
'value' => 'Anthony',
),
5 =>
array (
'id' => 8058,
'key' => 'Payer last name',
'value' => 'Evans',
),
6 =>
array (
'id' => 8059,
'key' => 'Payment type',
'value' => 'instant',
),
7 =>
array (
'id' => 8060,
'key' => '_paypal_status',
'value' => 'completed',
),
8 =>
array (
'id' => 8061,
'key' => '_paypal_transaction_fee',
'value' => '0.47',
),
9 =>
array (
'id' => 8290,
'key' => 'TrackingNumber',
'value' => '10046182',
),
10 =>
array (
'id' => 8291,
'key' => 'CarrierName',
'value' => 'SEABOURNE',
),
11 =>
array (
'id' => 10349,
'key' => '_alg_wc_custom_order_number',
'value' => '6',
),
),
'line_items' =>
array (
48 =>
array (
),
),
'tax_lines' =>
array (
50 =>
array (
),
),
'shipping_lines' =>
array (
49 =>
array (
),
),
'fee_lines' =>
array (
),
'coupon_lines' =>
array (
51 =>
array (
),
),
);
foreach($test['meta_data'] as $data){
if($data['key'] === "TrackingNumber"){
echo "The tracking number is: " . $data['value'];
}
}
