QR code payment (CZ)

A simple library to generate QR payment code for Czech Republic. All methods are documented in source code.

See also QR code payment generator for Slovak, Hungarian or European Union accounts.

Using Symfony? See the QR Payment Bundle.

Installation

Via composer: composer require rikudou/czqrpayment

Usage

You can create the QR payment for an object implementing \Rikudou\Iban\Iban\IbanInterface or from account number and bank account (which is then converted to \Rikudou\Iban\Iban\CzechIbanAdapter object).

See rikudou/iban for description of the interface and classes which let you for example validate the iban and/or the bank account number and bank code.

From IbanInterface implementing classes:

From account number and bank code directly:

Setting payment details

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

Using associative array

Using methods

Exceptions

Description of exceptions thrown:

• __construct()
  • InvalidArgumentException - if you provide options in constructor and any of those options does not exist
  • \Rikudou\CzQrPayment\Exception\InvalidValueException - if any of the options contains an asterisk
  • TypeError - if any of the values is not assignable to the properties after standard php conversions
• setOptions() - same as constructor
• getQrString()
  • \Rikudou\CzQrPayment\Exception\InvalidValueException - if any of the options contains an asterisk or if the iban is not valid
• getQrImage()
  • \Rikudou\CzQrPayment\Exception\MissingLibraryException - if the endroid/qr-code library is missing

All of these exceptions (except InvalidArgumentException and TypeError) extend the base \Rikudou\CzQrPayment\Exception\QrPaymentException.

QR Code image

This library provides many implementations of QR code image using its sister library rikudou/qr-payment-qr-code-provider. If any supported QR code generating library is installed, the method getQrCode() will return an instance of \Rikudou\QrPaymentQrCodeProvider\QrCode which can be used to get an image containing the generated QR payment data.

\Endroid\QrCode\QrCode

Example

Options

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 - ISO 4217 code for currency, defaults to CZK
• string $comment - the payment comment, has no default
• int $repeat - the number of days that the payment should be repeated if it fails, defaults to 7
• string $internalId - internal id of the payment, has no default
• DateTimeInterface dueDate - the due date for payment, has no default
• float $amount - the amount for the payment, shouldn't have more than 2 decimal places, has no default
• string $country - ISO 3166-1 alpha-2 code for country, defaults to CZ
• bool $instantPayment - whether the payment should be made as instant instead of standard payment (depends on bank support)

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

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