Tutoriel Paypal Express Checkout

PHP

Bonjour !

Je ne sais pas si c'est la bonne section pour cette question mais bref..

Pour un site Web, je dois faire un système d'abonnement et donc de payement par Paypal. Seulement, je n'avais jamais fait cela auparavant.

J'ai vu le nouveau tutoriel de Grafikart sur le Paypal Express Checkout mais malheureusement, ayant regardé quelques parties du tutoriel, il me semble qu'il est en orienté objet et je ne connais justement pas cet aspect là de PHP (et je déteste avoir du code que je ne comprends pas sur mes sites).

Je me demandais si Grafikart prévoyait un tutoriel là-dessus mais de manière procédurale ou si vous connaissiez des sites qui l'apprennent.

Je vous remercie.
Boris

Salut, l'API a un peux étais modifier mais elle est toujours pareil voir même simplifier je trouve

<?php $email = "Tonemail@email.com"; $price = 15; // CONFIG: Enable debug mode.

Tu as juste a modifier a ta guise ;)

La tu est en mode Debug + Sandbox tu soit passer a 0 en haut en situation réel, tu peux laisser en Sandbox pour tester

PS: tu risques de galerer a créé un compte sous Sandbox tu doit allez sur http://fr.fakenamegenerator.com/ et généré une personne copier ça carte bancaire etc et tu pourras payer ;)

Et pour faire payer la personne rien de bien compliquer
<?php
$price = 15;
$email = "tonemail@email.com";
$desc = "Canapé en cuir";
$number = 1;
$currency = "EUR";
$paypalurl = "https://www.sandbox.paypal.com/cgi-bin/webscr?cmd=_xclick&amount=".urlencode($price)."&business=".urlencode($email)."&item_name=".urlencode($desc)."&item_number=".urlencode($number)."&return=http://Si il a bien payer/"."&rm=2&notify_url=http://IPNPaypal/ipn.php"."&cancel_return=http://Si il annule.com"."&no_note=1&currency_code=".urlencode($currency)."";
?>
<a href="<?= $paypalurl ?>"><?= $paypalurl ?></a>

Modifier bien tes lien a la fin après les HTTP au debut de paypalurl j'ai mis sandbox.paypal.com si tu est plus en test (sandbox) tu as juste a enlever le sandbox.php
