===============

[](#paybysquare-php)

**[Live Demo](https://pbs.engazan.eu)**

Požiadavky
----------

[](#požiadavky)

- PHP 8.0+
- `xz` nainštalovaný na serveri (`apt install xz-utils` / `yum install xz` / `brew install xz`)
- PHP extension `gd` (pre renderovanie QR obrázkov)

Inštalácia
----------

[](#inštalácia)

```
composer require engazan/pay-by-square
```

Použitie
--------

[](#použitie)

```
use Engazan\PayBySquare\Generator;
use Engazan\PayBySquare\QrStyle;

$qr = (new Generator())
    ->setIban('SK7700000000000000000000')   // povinné, bez medzier
    ->setSwift('CEKOSKBX')
    ->setAmount(49.99)                       // povinné
    ->setRecipient('Jozko Mrkvicka')
    ->setVariableSymbol('20240001')          // max 10 číslic
    ->setConstantSymbol('0308')              // max 4 znaky
    ->setSpecificSymbol('9999')
    ->setPaymentReference('/VS1234/SS5678')   // max 35 znakov
    ->setNote('Faktura č. 2024/001')         // max 35 znakov
    ->setDueDate(new DateTime('+14 days'))
    ->setStyle(QrStyle::PayBySquare);
```

### Výstupné metódy

[](#výstupné-metódy)

```
// HTML  tag – priamo do šablóny
echo $qr->getImgTag(300);

// Len data URI
$uri = $qr->getDataUri(300);
echo "";

// Uložiť PNG súbor
$qr->saveToFile('/var/www/qr/platba.png', 300);

// Surové PNG bajty (napr. pre HTTP response)
header('Content-Type: image/png');
echo $qr->getPngBytes(300);

// Len Pay by square reťazec (ak máš vlastný QR renderer)
$string = $qr->generateString();
```

Štýly QR kódov
--------------

[](#štýly-qr-kódov)

Vizuálny štýl QR kódu sa nastavuje cez `setStyle()`:

```
use Engazan\PayBySquare\QrStyle;

$qr->setStyle(QrStyle::PayBySquare);
```

ŠtýlHodnotaPopis`QrStyle::Default``default`Čistý QR kód, biele pozadie`QrStyle::Transparent``transparent`QR kód s priehľadným pozadím (PNG s alpha kanálom)`QrStyle::PayBySquare``pay_by_square`Modrý rám + "PAY by square" footer, biele pozadie`QrStyle::PayBySquareTransparent``pay_by_square_transparent`Modrý rám + "PAY by square" footer, priehľadné pozadie QR oblasti### Zmena cesty k xz

[](#zmena-cesty-k-xz)

```
$qr->setXzPath('/usr/local/bin/xz');
```

### Ošetrenie výnimiek

[](#ošetrenie-výnimiek)

```
use Engazan\PayBySquare\Exception\ValidationException;
use Engazan\PayBySquare\Exception\PayBySquareException;

try {
    echo $qr->getImgTag();
} catch (ValidationException $e) {
    // Chýba IBAN, suma getMessage();
} catch (PayBySquareException $e) {
    // xz binárka sa nenašla, kompresia zlyhala...
    echo 'Chyba generovania: ' . $e->getMessage();
}
