Yo , c'est la glace de Mcdo :D
Je vais vous faire un putain de tutoriel hihi
j'ai mis en place un systeme de payment via paypal
Tout dabors : crée un dossier Paypal
crée un fichié : class.paypal.php
code a mettre :
PHP:
class PayPalIPN {

}
/**

public function getPaypalUri()

}
}
Puis après aller exécuter cette requête SQL pour ajouter la table requise:
Ensuite, sur votre page de la boutique, allez ajouter ce tout en haut de votre fichier .php:
PHP:
/**
* Set cache headers to prevent the user from doing a duplicate of form submission
*/ header("Expires: Mon, 26 Jul 1997 05:00:00 GMT"); header("Last-Modified: " . gmdate("D, d M Y H:i:s") . "GMT"); header("Cache-Control: no-store, no-cache, must-revalidate"); header("Cache-Control: post-check=0, pre-check=0", false); header("Pragma: no-cache"); //header("HTTP/1.1 200 OK"); require dirname(__FILE__) . DIRECTORY_SEPARATOR . "app/management/paypal/class.paypal.php";
use PayPalIPN; $ipn = new PayPalIPN(); $orderPlaced = true; // Set the response array $response = ['status' => 'false', 'title' => 'Payment Error', 'message' => '']; $verified = $ipn->verifyIPN();
if($verified) {
$username = $users->getUsername($uid);
// Payment has been verified, so get details
$payer_email = $_POST['payer_email'];
$verify_sign = $_POST['verify_sign'];
$txn_id = $_POST['txn_id'];
$payment_date = $_POST['payment_date'];
$package = $_POST['item_number'];
$amount = $_POST['payment_gross'];
$item_name = $_POST['item_name'];
// Make sure the transaction id has not already been used
$stmt = $db->query("SELECT `id` FROM `cms_transactions` WHERE `transaction_id` = :tid LIMIT 1");
$stmt->bindParam(':tid', $txn_id, $db->PARAM_STR);
$stmt->execute();
if($stmt->rowCount() < 1) {
// If the transaction id has not been used, match the package id against the one in db.
$stmt = $db->query("SELECT `diamonds` FROM `cms_diamond_packages` WHERE `id` = :id AND `price` = :a LIMIT 1");
$stmt->bindParam(':id', $package, $db->PARAM_INT);
$stmt->bindParam(':a', $amount, $db->PARAM_STR);
$stmt->execute();
if($stmt->rowCount() > 0) {
$diamonds = $stmt->fetchColumn();
// Payment has been successfully placed, insert it into the transactions table.
$stmt = $db->query("INSERT INTO `cms_transactions` (`user_id`,`gateway`,`transaction_id`,`amount`,`package`,`email`,`nonce`,`purchase_date`) VALUES (:uid,:g,:tid,:a,:p,:e,:n,:d)");
$data = [
':uid' => $_SESSION['user']['id'],
':g' => 'paypal',
':tid' => $txn_id,
':a' => $amount,
':p' => $package,
':e' => $payer_email,
':n' => $verify_sign,
':d' => NULL
];
$stmt->execute($data);
// Give user paid currencies or VIP
$users->updateUser($uid, 'diamonds', ($users->getUserInfo($uid, 'diamonds') + $diamonds));
if(!$users->hasBadge($uid, 'SDB01')) // If user doesn't have badge give it to them
$users->giveUserBadge($uid, 'SDB01');
// Set response to success
$response['status'] = "true";
$response['title'] = "Payment Success";
$response['message'] = 'You have successfully bought '.$diamonds.' <img src="'.$url.'/static/img/diamonds.png" />.<br /> You can buy all sorts of things with diamonds. Visit our other shops to buy credits, duckets, rares, boxes, VIP etc.';
// Put log as success
$ipn->putLog("SUCCESS", json_encode($_POST, true));
$ipn->putLog("SUCCESS", "User {$username} has successfully bought package {$package} containing {$diamonds} with a price of {$amount} using payer email {$payer_email} on {$payment_date} with ID: {$txn_id}");
} else {
// Put log as the user trying to exploit the system by changing price for a package
$response['message'] = "Package ID doesn't match its pricetag: {$verified}";
$ipn->putLog("ERROR", "User {$username} tried to spoof {$package} with price {$amount} using transaction id {$txn_id} with payer email {$payer_email} on {$payment_date}.");
}
} else {
// User tried to duplicate this package, set the response and put the error log
$response['message'] = "You have already bought a package using this Transaction ID once <b>{$txn_id}</b>.";
$ipn->putLog("ERROR", "User {$username} tried to duplicate package {$package} using transaction id {$txn_id} with payer email {$payer_email} on {$payment_date}.");
}
} else {
$orderPlaced = false;
}
Donc, lorsque quelqu'un clique sur un bouton d'achat, ils doivent être redirigés vers PayPal avec les bonnes valeurs, qui est d'où cela vient dans maniable:
PHP:
<?php echo '<form action="'.$ipn->getPaypalUri().'" method="post" accept-charset="utf8">
<input type="hidden" name="cmd" value="_xclick">
<input type="hidden" name="lc" value="US">
<input type="hidden" name="currency" value="currency they're paying in">
<input type="hidden" name="item_name" value="title of what they're buying">
<input type="hidden" name="business" value="Your PayPal Business Email">
<input type="hidden" name="amount" value="price of what they're buying">
<input type="hidden" name="item_number" value="package id of what they're buying">
<input type="hidden" name="return" value="enter url here that returns to your shop page">
<input type="hidden" name="cancel_url" value="enter url here that returns to your shop page">
<input type="hidden" name="rm" value="2">
<input type="hidden" name="quantity" value="1">
<button style="margin:3px 3px 3px;float:left;padding:.375rem 0.9rem;" type="submit" class="btn btn-green" name="submit">
<big>_diamonds_ <img src="'.$url.'/static/img/diamonds.png" /></big>
<br />
<small>_price_ '.$currency.'</small>
</button>
</form>'; ?>
Pour vérifier si un processus a été fait, vous pouvez imprimer à l'utilisateur les détails de la réponse, comme indiqué ci-dessous:
PHP:
<?php if($orderPlaced): ?>
<script type="text/javascript">
window.alert("Title: <?php echo $response['title']; ?>, Response: <?php echo $response['message']; ?>");
</script> <?php endif; ?>
Obtenir le cacert.pem copier les données à partir d' ici: https://github.com/paypal/ipn-code-samples/blob/master/php/cert/cacert.pemAint va être trop précis à ce sujet, donc si vous avez obtenu Pour toute question écrire un commentaire. * Il y aura ajouté une fonctionnalité, de sorte que toutes les fois qu'un client utilisateur visite, il vérifie les transactions existantes actuelles faites par l'utilisateur, pour être sûr que l'utilisateur n'a pas remboursé le paiement, et si elles ont, il va interdire automatiquement leur.
