Variable error within the function

Question

I’m having problems and for what I searched in the internet forums, others have the same doubt that I.

I cannot use PHP variables within the transaction function. How do I set a variable?

For example, this does not work:

$id = $_POST["id_saida"];
$nome = $_POST["nome_produto"];
$valor   = $_POST["valor_final"];


class CreatePaymentRequestLightbox
{
public static function main()
{

Original:

$paymentRequest->addItem('0001', 'Notebook prata', 1, 430.00); //original

How I wish it would work:

$paymentRequest->addItem($id, $nome, $n, $valor); // como gostaria

Only it’s wrong, it’s empty. What to do?

<?php

require_once "includes/ps/PagSeguroLibrary/PagSeguroLibrary.php";
$form = $_GET['form'];
if ($form == "pagseg"){
echo "ok";
$id_transfer = $_POST["id_transfer"];
$id = $_POST["id_saida"];
$nome = $_POST["nome_produto"];
$valor   = $_POST["valor_final"];

$v1 ="teste";

Answer 1

I do not know if you have put enough code and information to indicate clearly where the problem is but surely there is something that will help or solve the problem. Probably just transfer the declaration of variables that are "loose" on the page and put inside the method where you need them, in case the main class CreatePaymentRequestLightbox. I have my doubts if you need this class. You are probably copying a code that you do not understand.

<?php
require_once "includes/ps/PagSeguroLibrary/PagSeguroLibrary.php";
class CreatePaymentRequestLightbox {

public static function main() {
    $form = $_GET['form'];
    $id_transfer = $_POST["id_transfer"];
    $id = $_POST["id_saida"];
    $nome = $_POST["nome_produto"];
    $valor   = $_POST["valor_final"];
    $v1 ="teste";

    $paymentRequest = new PagSeguroPaymentRequest();
    $paymentRequest->setCurrency("BRL");
    $paymentRequest->addItem($v1, 'Notebook prata', 1, 430.00);
    $paymentRequest->setReference("REF123");
    $sedexCode = PagSeguroShippingType::getCodeByType('SEDEX');
    $paymentRequest->setShippingType($sedexCode);
    $paymentRequest->setShippingAddress(
        '01452002',
        'Av. Brig. Faria Lima',
        '1384',
        'apto. 114',
        'Jardim Paulistano',
        'São Paulo',
        'SP',
        'BRA'
    );
    $paymentRequest->setSender(
        'João Comprador',
        '[email protected]',
        '11',
        '56273440',
        'CPF',
        '156.009.442-76'
    );
    $paymentRequest->setRedirectUrl("http://www.lojamodelo.com.br");
    $paymentRequest->addMetadata('PASSENGER_CPF', '15600944276', 1);
    $paymentRequest->addMetadata('GAME_NAME', 'DOTA');
    $paymentRequest->addMetadata('PASSENGER_PASSPORT', '23456', 1);
    $paymentRequest->addParameter('notificationURL', 'http://www.lojamodelo.com.br/nas');
    $paymentRequest->addParameter('senderBornDate', '07/05/1981');
    $paymentRequest->addIndexedParameter('itemId', '0003', 3);
    $paymentRequest->addIndexedParameter('itemDescription', 'Notebook Preto', 3);
    $paymentRequest->addIndexedParameter('itemQuantity', '1', 3);
    $paymentRequest->addIndexedParameter('itemAmount', '200.00', 3);
    try {
        $credentials = new PagSeguroAccountCredentials("[email protected]",
            "EDC2E4A8E6B246D29C713FB97C26808E");
        $onlyCheckoutCode = true;
        $code = $paymentRequest->register($credentials, $onlyCheckoutCode);
        self::printPaymentUrl($code);
    } catch (PagSeguroServiceException $e) {
        die($e->getMessage());
    }
  }

  public static function printPaymentUrl($code) {
    if ($code) {
        echo "<h2>Criando requisi&ccedil;&atilde;o de pagamento</h2>";
        echo "<p>Code: <strong>$code</strong></p>";
        echo "<script>
        PagSeguroLightbox('".$code."');
              </script>";
    }
  }
 }
}
CreatePaymentRequestLightbox::main();

I put in the Github for future reference.

Answer 2

The variables you are trying to use in the object method $paymentRequest shall be initialised within the main (main), so they will be recognized in the scope.

Answer 3

For you to use these parameters throughout the application (or in more than one class), the best, in my opinion, is to create a constant. Example:

define("ID", $_POST["id_saida"]);
define("NOME", $_POST["nome_produto"]);
define("VALOR", $_POST["valor_final"])  ;

class CreatePaymentRequestLightbox
{
    public static function main()
    {
        $id = ID;
        $nome = NOME;
        $valor   = VALOR;
    }
}
