QR code payment (SK)

A simple library to generate QR payment code for Slovakia. All methods are documented in source code. This library needs the xz binary to be present. If the binary is not in your PATH, you must set the path to xz manually.

See also QR code payment generator for Czech or European accounts.

Using Symfony? See the QR Payment Bundle.

Installation

Via composer: composer require rikudou/skqrpayment

Usage

Extending the QrPayment class was deprecated as of 2.4.0

You can create the Qr payment from IBAN or BBAN.

From IBAN:

<?php

use rikudou\SkQrPayment\QrPayment;
use rikudou\SkQrPayment\Structs\IbanBicPair;

$payment = QrPayment::fromIBAN(new IbanBicPair('SK6807200002891987426353'));
// or multiple accounts
$payment = QrPayment::fromIBANs([
    new IbanBicPair('SK6807200002891987426353'),
    new IbanBicPair('SK3302000000000000012351')
]);
// you can also specify the BIC (SWIFT) code in the IbanBicPair
$payment = QrPayment::fromIBAN(new IbanBicPair('SK6807200002891987426353', 'NBSBSKBX'));
// if you don't specify the BIC it will be guessed automatically

From account number and bank code (BBAN):

<?php

use rikudou\SkQrPayment\QrPayment;
use rikudou\SkQrPayment\Structs\IbanBicPair;
use rikudou\SkQrPayment\Structs\SlovakianIbanAdapter;

$payment = QrPayment::fromIBAN(
    new IbanBicPair(
        new SlovakianIbanAdapter('0123123123', '0900')
    )
);

Setting payment details

There are two approaches to setting payment details. You can set them in associative array or using the methods provided in the class.

Using associative array

<?php

use rikudou\SkQrPayment\QrPayment;
use rikudou\SkQrPayment\QrPaymentOptions;
use rikudou\SkQrPayment\Structs\IbanBicPair;

$payment = QrPayment::fromIBAN(new IbanBicPair('SK6807200002891987426353'))->setOptions([
  QrPaymentOptions::VARIABLE_SYMBOL => 123456,
  QrPaymentOptions::AMOUNT => 100,
  QrPaymentOptions::CURRENCY => "EUR",
  QrPaymentOptions::DUE_DATE => date("Y-m-d", strtotime("+14 days"))    
]);

Using methods

<?php
use rikudou\SkQrPayment\QrPayment;
use rikudou\SkQrPayment\Structs\IbanBicPair;

$payment = QrPayment::fromIBAN(new IbanBicPair('SK6807200002891987426353'))
    ->setVariableSymbol(123456)
    ->setAmount(100)
    ->setCurrency("EUR")
    ->setDueDate(date("Y-m-d", strtotime("+14 days")));

Exceptions

The only exception thrown by this library is rikudou\SkQrPayment\QrPaymentException.

Methods that can throw exception:

• IbanBicPair::__construct() - if the IBAN is of invalid type (not string or IbanInterface), if the BIC is not supplied and could not be automatically guessed and if the IBAN is not valid
• QrPayment::getQrString() - if there are no IBANs set
• QrPayment::getQrImage() - if the endroid\qrcode is not loaded
• QrPayment::fromIBANs() - if any of the the IBANs is not instance of IbanBicPair
• QrPayment::getXzBinary() - if the xz binary is not available
• QrPayment::getDueDate() - if the supplied date could not be parsed into DateTime object

List of public methods

Constructor

Deprecated as of 2.5.0

Params

• int|string $account - the account number

$payment = QrPayment::fromIBAN(new IbanBicPair('SK6807200002891987426353'))->setOptions([
  QrPaymentOptions::AMOUNT => 100
]);

getIBAN()

Deprecated as of 2.5.0

Returns the IBAN, either from supplied IBAN or generated from account number and bank code.

Returns

string

Example

<?php

use rikudou\SkQrPayment\QrPayment;
use rikudou\SkQrPayment\Structs\IbanBicPair;

$payment = QrPayment::fromIBAN(new IbanBicPair('SK6807200002891987426353'));
$myIBAN = $payment->getIBAN();

getQrString()

Returns the string that should be encoded in QR image.

Returns

string

Example

<?php
use rikudou\SkQrPayment\QrPayment;
use rikudou\SkQrPayment\QrPaymentOptions;

static fromIBAN()

Returns new instance of the payment object created from IBAN.

Params

Passing string as the $iban argument is deprecated as of 2.5.0

removeIban()

Removes the IBAN from payment. If the IBAN is not present, does nothing (e.g. you don't need to check whether the IBAN was actually added to payment before attempting to remove).

}

setXzBinary()

Params

• string $binaryPath - the path to the xz binary

Returns

Returns itself, you can use this method for chaining.

Example

echo $payment->getXzBinary(); // prints /usr/bin/xz or something similar
$payment->setXzBinary("/path/to/xz");
echo $payment->getXzBinary(); // prints /path/to/xz

Options

Direct access to properties (e.g. $payment->amount = 100) was deprecated as of 2.4.0

This is a list of options you can set.

• int variableSymbol - the variable symbol, has no default
• int specificSymbol - the specific symbol, has no default
• int constantSymbol - the constant symbol, has no default
• string currency - three letter code for currency, defaults to EUR
• string comment - the payment comment, has no default
• string|DateTime dueDate - the due date for payment, should be an instance of DateTime class or a string that can be parsed by strtotime(), has no default
• float amount - the amount for the payment, can't have more than 2 decimal places, has no default
• country - two letter code for country, defaults to SK

All of these options can be set using the QrPaymentOptions helper class as constants for constructor or setOptions() or as methods.

For example, the amount can be set in array using the constant QrPaymentOptions::AMOUNT or using the method setAmount().
