README

qris-dynamicify is a powerful and lightweight composer library for effortlessly transforming static QRIS (Quick Response Code Indonesian Standard) into dynamic QRIS. This tool is designed for developers and businesses in Indonesia who need to generate transaction-specific QR codes with dynamic amounts, streamlining the payment process for modern applications.

The project solves the problem of static, non-specific QRIS codes by allowing you to programmatically inject transaction details like price and taxes, making the payment experience seamless for both merchants and customers.

Key Features

• Static to Dynamic Conversion: Convert any valid static QRIS string or image into a dynamic one.
• Set Transaction Amount: Easily set a specific price for the transaction.
• Add Tax/Service Fee: Include nominal or percentage-based taxes and fees.
• QRIS Metadata Extraction: Parse and retrieve merchant information from any QRIS code.
• Multiple Input Formats: Accepts QRIS data from a raw string or an image file (.png, .jpg, .jpeg).
• Flexible Output: Generate a dynamic QRIS as a raw string or save it directly as a QR code image.
• PHP-Friendly: Fully written in PHP with type-safe methods for a clean development experience.
• Lightweight: Minimal dependencies to keep your project lean.

Usage Instructions

Here’s how to get started with qris-dynamicify.

Basic Example: From a Static QRIS String

require_once 'vendor/autoload.php';

use XanderID\QrisDynamicify\QrisDynamicify;
use XanderID\QrisDynamicify\QrisException;

try {
    $staticQris = "00020101021126590013ID.CO.GOPAY.WWW021500000000000000000303UKE51450014ID.CO.GOPAY.MERCHANT02151234567890123450303UKE5204581253033605802ID5917MERCHANT NATIONAL6011JAKARTA SEL61051215062070703A01";

    $dynamicQris = QrisDynamicify::fromString($staticQris);

    // Set price and tax
    $dynamicQris->setPrice(50000)->setTax("10%");

    // Get the dynamic QRIS string
    echo "Dynamic QRIS String: " . $dynamicQris . PHP_EOL;

    // Save as PNG file
    $dynamicQris->writeToFile("dynamic-qris.png");
    echo "Successfully generated dynamic-qris.png" . PHP_EOL;

} catch (QrisException $e) {
    echo "Error: " . $e->getMessage() . PHP_EOL;
}

Example: From a QRIS Image File

require_once 'vendor/autoload.php';

use XanderID\QrisDynamicify\QrisDynamicify;
use XanderID\QrisDynamicify\QrisException;

try {
    $dynamicQrisFromFile = QrisDynamicify::fromFile("path/to/static-qris.png");

    // Set price and fixed tax
    $dynamicQrisFromFile->setPrice(125000)->setTax(5000);

    // Save new QRIS file
    $dynamicQrisFromFile->writeToFile("new-dynamic-qris.png");
    echo "Successfully generated new-dynamic-qris.png from file" . PHP_EOL;

} catch (QrisException $e) {
    echo "Error: " . $e->getMessage() . PHP_EOL;
}

FAQ

Q: What is the difference between static and dynamic QRIS? A: A static QRIS contains only the merchant's information. The customer has to manually input the transaction amount. A dynamic QRIS is generated for a single transaction and includes the amount, making the payment process faster and less error-prone.

Q: Can I use this for any QRIS code from any provider? A: Yes, this library should work with any valid QRIS code that complies with the Bank Indonesia standard.

Why this project?

In the rapidly growing digital economy of Indonesia, QRIS has become a ubiquitous payment method. However, many smaller businesses still rely on static QRIS displays, which require manual entry of payment amounts. This can be slow and prone to errors. qris-dynamicify was created to bridge this gap, providing developers with a simple, powerful tool to integrate dynamic QRIS generation into their applications. Whether you're building a POS system, an e-commerce platform, or a donation portal, this library helps you create a smoother, more professional payment experience.
