Please I need help with coding

[caslas]

Good day, I have a pin/token system stored in mysql database for online registration, I also have an online payment system that accepts debit cards. I need a code so as to automatically show a pin to a user who has made payment and also an sms/email carrying the pin/token.
i have a payment page that verifies cards and debits the user called verify.php with code <?php
/**
 * Verify SimplePay transaction
 */

$private_key = 'test_pr_demo';  // put here your private key

// Retrieve data returned in payment gateway callback
$token = $_POST["sp_token"];
$amount = $_POST["sp_amount"];
$amount_currency = $_POST["sp_currency"];
$sp_status = $_POST["sp_status"];
$transaction_id = $_POST["transaction_id"]; // we don't really need this here, is just an example

$data = array(
    'token' => $token,
    'amount' => $amount,
    'amount_currency' => $amount_currency
);
$data_string = json_encode($data);

// Call to charge/verify a payment
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, 'https://checkout.simplepay.ng/v2/payments/card/charge/');
curl_setopt($ch, CURLOPT_USERPWD, $private_key . ':');
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
curl_setopt($ch, CURLOPT_CUSTOMREQUEST, 'POST');
curl_setopt($ch, CURLOPT_POST, true);
curl_setopt($ch, CURLOPT_POSTFIELDS, $data_string);
curl_setopt($ch, CURLOPT_HEADER, true);
curl_setopt($ch, CURLOPT_HTTPHEADER, array(
    'Content-Type: application/json',
    'Content-Length: ' . strlen($data_string)
));

$curl_response = curl_exec($ch);
$curl_response = preg_split("/\r\n\r\n/", $curl_response);
$response_content = $curl_response[1];
$json_response = json_decode(chop($response_content), TRUE);
print_r($json_response);
$response_code = curl_getinfo($ch, CURLINFO_HTTP_CODE);

curl_close($ch);

if ($response_code == '200') {
    // even is http status code is 200 we still need to check transaction had issues or not
    if ($json_response['response_code'] == '20000') {
        // card was successfully charged
        header('Location: success.html');
    } else {
        // failed to charge the card
        header('Location: failed.html');
    }
} else if ($sp_status == 'true') {
    // even though it failed the call to card charge, card payment was already processed
    header('Location: success.html');
} else {
    // failed to charge the card
    header('Location: failed.html');
}
?>

and after, it redirects to success.html. My pins are stored in a database. thank you.

You have all this code, so where is the problem? Where is the code to do this thing you are asking about? Do you want us to write it for you?

 

Show us the code that is not working and perhaps someone will help you over that hurdle.
