№22 Dars — Yii da paypalni integratsiya qilish.

PayPal o`zi nima?

Yiida PayPal ning maxsus extensionlari mavjud. Bulardan hozircha bittasi bilan tanishib qanday ishlashi haqida gaplashamiz. PayPal o`zi o`zaro pul aylanmasini taminlab beruvchi veb ilova. Bu yerdan pul o`tkazmalar qilayotganda ro`yxatdan o`tgan bo`lishingiz kerak. Ya`ni akkountingiz bo`lishi kerak. Bu ilovada ham siz ishlaringizni test qilib ko`rishingiz uchun sandbox turidan foydalanishingiz kerak.

Paypal o`zining API siga ega va biz undan Yii da foydalanishimiz mumkin.

Kerakli ishlar:

1. Komponentani ishlatish uchun Yii framework 1.1 va undan yuqori versiyasi kerak bo`ladi
2. PHP CURL extensioni o`rnatilgan va yoqilgan bo`lishi kerak
3. PayPal ma`lumotlari (username, password, signature) lar bo`lishi kerak
4. Exstensioni quyidagi havola orqali yuklab olishingiz kerak bo`ladi http://www.yiiframework.com/extension/paypal/

Bog`lash:

Ushbu murojaat orqali extensionni yuklab olishingiz kerak. Keyin main.php ga quyidagicha kod kiritishingiz kerak bo`ladi.

'Paypal' => array(
    'class'=>'application.components.Paypal',
    'apiUsername' => 'YOUR_API_USERNAME',  // paypaldagi usernameingiz
    'apiPassword' => 'YOUR_API_PASSWORD',  // paypaldagi passwordingiz
    'apiSignature' => 'YOUR_API_SIGNATURE',  // yagona tarzdagi kalit 
    'apiLive' => false,  // false bo`lsa sandbox orqali ishlatish, ya`ni test qilish uchun ishlatiladi. Agar haqiqiy pul aylanmasini o`rnatmoqchi bo`lsangiz true qilib qo`yish talab qilinadi. 
 
    'returnUrl' => 'paypal/confirm/', //PayPal serveridan ish muvofaqiyatli kelsa shu urlga yo`naltiradi.
    'cancelUrl' => 'paypal/cancel/', //agar ish muvofaqiyatsiz bo`lsa ushbu urlga yo`naltiradi.
 
    // qaysi birlikda pul aylanmasini amalga oshirishingiz
    'currency' => 'USD',
 
    // izohlar uchun 
    //'defaultDescription' => '',
 
    // mahsulot soni 
    //'defaultQuantity' => '1',
),

PayPal ni komponentidan foydalanish kontrollerga quyidagicha kod yozishimiz orqali amalga oshadi.

class PaypalController extends Controller
{
    public function actionBuy(){
  
        $paymentInfo['Order']['theTotal'] = 10.00;
        $paymentInfo['Order']['description'] = "Some payment description here";
        $paymentInfo['Order']['quantity'] = '1';
 
        // paypalni chaqirish 
        $result = Yii::app()->Paypal->SetExpressCheckout($paymentInfo); 
        //jarayon vaqtida xatolik chiqsa 
        if(!Yii::app()->Paypal->isCallSucceeded($result)){ 
            if(Yii::app()->Paypal->apiLive === true){
                //Live bo`lsa. Agar qandaydir xatolik bo`lsa shu xatolikni oladi.
                $error = 'We were unable to process your request. Please try again later';
            }else{
                //Sandbox bo`lsa. Agar xatolik bo`lsa shu haqdagi xatolik xabari keladi.

Siz platformangizda «Buy» actioniga murojaat qilasiz. Undan siz yuklab olgan komponentingizga boradi. U yerdan PayPal serveriga userni yo`naltiradi. U yerdan muvofaqiyatli qaytsa «confirm» actioniga keladi va jarayon oxirgi bosqichigacha xatoliksiz amalga oshib kelsa o`zingiz uchun ham ushbu pul o`tkazmalarini saqlash uchun kodlar yozishingiz mumkin bo`ladi.

Ko`rib turganingizdek bu foydalanuvchining bosqichlar jarayoni. Sizning serveringizdan paypal serveriga yo`naltiriladi va u yerda foydalanuvchi accounti orqali kirib to`lovni amalga oshiradi. Har bir to`lovning yagona idsi mavjud.

PayPal ni platformangizga biriktirganingizdan keyin har xil o`zgarishlar qilib ko`rib xar bir parametrni nima ish qilishini yana bir bor bilib olishingiz mumkin bo`ladi.
