Question

を呼び出して、私は次のエラーが表示されます

Fatal error: Uncaught Error: Call to undefined function charge() in D:......\square\1.php on line 28

続行するかどうかはわからないだけれども、私が行方不明$access_tokenを追加しましたか？不足している充電機能のバグを修正するにはどうすればよいですか？

<?php 
require 'vendor/autoload.php'; 

$access_token = 'sandbox-abcdefghijkl_mnopqrstivwxyzzz'; 
# setup authorization 
\SquareConnect\Configuration::getDefaultConfiguration()->setAccessToken($access_token); 
# create an instance of the Transaction API class 
$transactions_api = new \SquareConnect\Api\TransactionsApi(); 
$location_id = 'CBASEEum0KeFu_h-4VA4OWaV3F8gAQ'; 
$nonce = 'CBA15363g28251525625624455255A'; 

$request_body = array (
    "card_nonce" => $nonce, 
    # Monetary amounts are specified in the smallest unit of the applicable currency. 
    # This amount is in cents. It's also hard-coded for $1.00, which isn't very useful. 
    "amount_money" => array (
    "amount" => 100, 
    "currency" => "USD" 
), 
    # Every payment you process with the SDK must have a unique idempotency key. 
    # If you're unsure whether a particular payment succeeded, you can reattempt 
    # it with the same idempotency key without worrying about double charging 
    # the buyer. 
    "idempotency_key" => uniqid() 
); 

try { 
    $result = $transactions_api-charge($location_id, $request_body); 
    print_r($result); 
} catch (\SquareConnect\ApiException $e) { 
    echo "Exception when calling TransactionApi->charge:"; 
    var_dump($e->getResponseBody()); 
} 
?>

これはどこかからコピーして貼り付けましたか？

$transactions_api-charge 

は

$transactions_api->charge
