STRIPE Payment integration with PHP - php

Question

Have the below code - works fine.. BUT... As the DB is updated to PAID before the charge, and if the charge is declined, the DB is still updated to PAID.
Want to achieve -
If charge successful and not declined, charge customer THEN update DB to PAID..
NOT
Update DB to PAID, then charge customer...
// Create connection
$conn = mysqli_connect($hostname, $username,$password, $database);
// Check connection
if (!$conn) {
die("Connection failed: " . mysqli_connect_error());
}
$sql = "UPDATE details SET PaymentStatus='PAID' WHERE MembershipNo ='12345'";
if (mysqli_query($conn, $sql)) {
// starting the session
require_once('config.php');
$token = $_POST['stripeToken'];
$email = $_POST['stripeEmail'];
$SOSamount = ($_SESSION['price']*100);
$FirstName = ($_SESSION['FirstName']);
$LastName = ($_SESSION['LastName']);
$customer = \Stripe\Customer::create(array(
'email' => $email,
'source' => $token,
'description' => "$FirstName $LastName - Membership"
));
$charge = \Stripe\Charge::create(array(
'customer' => $customer->id,
'amount' => $amount,
'currency' => 'aud',
'description' => "Membership - $FirstName $LastName"
));
mysqli_close($conn);

Answer 1

You should wrap all calls to Stripe's API in a try/catch block to handle possible errors.
You can find more information in Stripe's API reference:
https://stripe.com/docs/api/php#errors
https://stripe.com/docs/api/php#error_handling
Basically, your code should look like this:
try {
$customer = \Stripe\Customer::create(...);
$charge = \Stripe\Charge::create(...);
} catch(\Stripe\Error\Card $e) {
// The card was declined, display an error message to your customer
// and end execution
} catch (Exception $e) {
// Another error happened, display an error message to your customer
// and end execution
}
// The charge was completed successfully, update your DB

Thx altoids
Found this snippet, moved Query..
if ($charge->paid == true) {
$conn = mysqli_connect($hostname, $username, $password, $database);
$sql = "UPDATE details SET PaymentStatus='PAID' WHERE MembershipNo ='12345'";
mysqli_query($conn, $sql);
}
