README

This package allows you to generate QR Codes.

Installation

You can install the package via composer:

composer require dominik-eller/laravel-qr-code

Usage

All QR codes are created via the QrCode facade. Call generate() to get a binary string, or toBase64() to get a data URI ready for use in an <img> tag.

URL

use Deller\QrCode\Facades\QrCode;

$qrCode = QrCode::create(‘url’)
    ->setUrl(‘https://example.com’)
    ->setSize(300)
    ->setColor([0, 0, 0])
    ->setBackgroundColor([255, 255, 255])
    ->setErrorCorrectionLevel(‘H’)
    ->generate();

Text

$qrCode = QrCode::create(‘text’)
    ->setText(‘Hello, World!’)
    ->setSize(300)
    ->generate();

E-Mail

$qrCode = QrCode::create(‘email’)
    ->setEmail(‘contact@example.com’)
    ->setSize(300)
    ->generate();

Opening the QR code encodes a mailto:contact@example.com link.

Phone number

$qrCode = QrCode::create(‘phone’)
    ->setPhoneNumber(‘+43123456789’)
    ->setSize(300)
    ->generate();

Opening the QR code encodes a tel:+43123456789 link.

Wi-Fi

WifiQrCode is not registered by default and must be added first:

use Deller\QrCode\Facades\QrCode;
use Deller\QrCode\Types\WifiQrCode;

QrCode::registerType(‘wifi’, WifiQrCode::class);

$qrCode = QrCode::create(‘wifi’)
    ->setSsid(‘MyNetwork’)
    ->setPassword(‘secret’)
    ->setEncryption(‘WPA’)   // WPA, WEP, or nopass
    ->setSize(300)
    ->generate();

Output formats

The default output format is PNG. Use setFormat() to switch to SVG or EPS:

$svg = QrCode::create(‘url’)
    ->setUrl(‘https://example.com’)
    ->setFormat(‘svg’)
    ->generate();

Base64 data URI

Use toBase64() to embed the QR code directly in HTML:

$dataUri = QrCode::create(‘url’)
    ->setUrl(‘https://example.com’)
    ->toBase64();

// <img src="{{ $dataUri }}">

Custom eye colors

The three finder-pattern squares ("eyes") can be colored independently:

$qrCode = QrCode::create(‘url’)
    ->setUrl(‘https://example.com’)
    ->setTopLeftEyeColor([255, 0, 0])
    ->setTopRightEyeColor([0, 0, 255])
    ->setBottomLeftEyeColor([0, 128, 0])
    ->generate();

Custom types

use Deller\QrCode\QrCode as BaseQrCode;

class VCardQrCode extends BaseQrCode
{
    public function getData(): string
    {
        return "BEGIN:VCARD\nVERSION:3.0\nFN:Jane Doe\nEND:VCARD";
    }
}

QrCode::registerType(‘vcard’, VCardQrCode::class);

$qrCode = QrCode::create(‘vcard’)->generate();
