What parameters do I pass to doExpressCheckouPaymentt()? - php

Question

I have this controller that is supposed to perform PayPal payments. The payment function is working well but on getting to success function I am getting an error Illegal string offset 'total' . I am passing $this->productData($request) as suggested in this question. I tried creating a variable $total = $response['AMT'] which is the response from setCheckoutDetails but I still got the same error. How do I go about it?
<?php
namespace App\Http\Controllers;
use Illuminate\Http\Request;
use Srmklive\PayPal\Services\ExpressCheckout;
class PayPalController extends Controller
{
private function projectData(Request $request){
// dd($request->all());
$item = [];
$datat = array_map(function($item){
return [
'name'=>$request->project_id,
'price'=>$request->budget,
'desc'=>'Deposit',
'qty'=>1
];
}, $item);
$data = [
'items'=>$datat,
'invoice_id' => uniqid(),
'invoice_description' => "Payment for Project No.".$request->project_id." Amount ".$request->budget,
'return_url' => route('payment.success'),
'cancel_url' => route('payment.cancel'),
'total'=>$request->budget
];
// dd($data);
return $data;
}
/**
* Responds with a welcome message with instructions
*
* #return \Illuminate\Http\Response
*/
public function payment(Request $request) {
$data = $this->projectData($request);
$provider = new ExpressCheckout;
$response = $provider->setExpressCheckout($data);
// dd($response);
// $response = $provider->setExpressCheckout($data, true);
return redirect($response['paypal_link']);
}
/**
* Responds with a welcome message with instructions
*
* #return \Illuminate\Http\Response
*/
public function cancel()
{
dd('Your payment is canceled. You can create cancel page here.');
}
/**
* Responds with a welcome message with instructions
*
* #return \Illuminate\Http\Response
*/
public function success(Request $request)
{
$provider = new ExpressCheckout;
$response = $provider->getExpressCheckoutDetails($request->token);
$token = $response['TOKEN'];
$payerId = $response['PAYERID'];
$total = $response['AMT'];
// dd($response);
if (in_array(strtoupper($response['ACK']), ['SUCCESS', 'SUCCESSWITHWARNING'])) {
// dd('Payment successful');
//Performing transaction
$payment_status = $provider->doExpressCheckoutPayment($token, $payerId, $this->projectData($request));
dd($payment_status);
}
dd('Something is wrong.');
}
}

Answer 1

You have to pass three parameters
data, token, PAYERID
Data can service information like
$data = array(
'total' => Total amount,
'invoice_id' => Invoicen number,
'invoice_description' => invoice descrption
);
And items as well which will contain name, price, desc and qty
