Return an array into payload-CodePudding

I need to send my cart contens in orderlines.

I can get the my orderlines as follows:

 foreach ($jcart->get_contents() as $item) {
                
            $queryString .= 'name'  . $count.  '=' . urlencode($item['name']);
            $queryString .= 'unit_price'  . $count . '=' . urlencode($item['price']);
            $queryString .= 'quantity' . $count . '=' . urlencode($item['qty']);
      $queryString .= 'total_amount' . $count . '=' . (urlencode($item['qty']) * urlencode($item['price']));
            // Increment the counter
          $count;   
        }

I want to send it as follows:

        $data = <<<DATA
        {
        "intent": "buy",
          "purchase_country": "GB",
          "purchase_currency": "GBP",
          "locale": "en-GB",
          "order_amount": 10,
          "order_tax_amount": 0,
            "order_lines": [
{
            "name": "name0",
            "quantity": quantity0,
            "unit_price": unit_price0,
            "total_amount": total_amount0
          },
    {
            "name": "name1",
            "quantity": quantity1,
            "unit_price": unit_price1,
            "total_amount": total_amount1
          }]
          
          
        }
        DATA;

How can I get my for each loop to populate the orderlines. so they can be send as example above

I tried:

 $data = <<<DATA
    {
    "intent": "buy",
      "purchase_country": "GB",
      "purchase_currency": "GBP",
      "locale": "en-GB",
      "order_amount": 10,
      "order_tax_amount": 0,
        "order_lines": [$queryString]
      
      
    }
    DATA;

This needs to be send as follows:

$url = "https://api.playground.klarna.com/payments/v1/sessions";
$curl = curl_init($url);
curl_setopt($curl, CURLOPT_URL, $url);
curl_setopt($curl, CURLOPT_POST, true);
curl_setopt($curl, CURLOPT_RETURNTRANSFER, true);
$headers = array(
   "Authorization: Basic $auth",
   "Content-Type: application/json",
);
curl_setopt($curl, CURLOPT_HTTPHEADER, $headers);
curl_setopt($curl, CURLOPT_POSTFIELDS, $data);
//for debug only!
curl_setopt($curl, CURLOPT_SSL_VERIFYHOST, false);
curl_setopt($curl, CURLOPT_SSL_VERIFYPEER, false);
$resp = curl_exec($curl);
curl_close($curl);

This does not work Any help welcome

CodePudding user response：

First you should populate the data into an array instead of a string.

$queryArray[] = [
    'name' => $item['name'],
    'quantity' => ...
]

Next encode the array with json.

$json = json_encode($queryArray);

Finally insert the encoded string into the payload.

$data = <<<DATA
{
  "intent": "buy",
  "purchase_country": "GB",
  "purchase_currency": "GBP",
  "locale": "en-GB",
  "order_amount": 10,
  "order_tax_amount": 0,
  "order_lines": $json
}
DATA;

CodePudding user response：

Create an array using the right structure and use json_encode() instead of trying to make the JSON string yourself.

// create data structure
$payload = [
    'intent'           => 'buy',
    'purchase_country' => 'GB',
    // ...
    'order_lines'      => [],
];

// Populate order-lines
foreach ($jcart->get_contents() as $item) {
    $payload['order_lines'][] = [
        'name'         => $item['name'],
        'unit_price'   => $item['price'],
        'quantity'     => $item['qty'],
        'total_amount' => $item['qty'] * $item['price'],
    ];
}

And use :

curl_setopt($curl, CURLOPT_POSTFIELDS, json_encode($payload));
