Laravel Simple Qrcode – Generate QR codes

Generating QR codes in a Laravel application can be easily accomplished using the Simple Qrcode package.

Step 1: Install Simple Qrcode

You can install the Simple Qrcode package via Composer. Run the following command in your terminal:

Step 2: Configure the Service Provider (Optional)

If you are using Laravel 5.5 or later, the package will automatically register itself. If you’re using an earlier version, you need to manually add the service provider to the config/app.php

Step 3: Create a Controller

Create a controller that will handle the QR code generation. You can do this with the following command:

Step 4: Generate QR Code in the Controller

In the newly created QrCodeController, you can add a method to generate the QR code. Below is an example:

Step 5: Define a Route

Now, define a route in routes/web.php to access the QR code generation method:

Step 6: Testing the QR Code Generation

1. Start your Laravel development server:

2. Visit http://localhost:8000/generate-qr-code?data=YourDataHere in your browser, replacing YourDataHere with the data you want to encode in the QR code.
3. You should see the generated QR code as a PNG image in your browser.

Step 7: Displaying QR Code in a View

If you want to display the QR code within a Blade view, you can modify your approach slightly. Create a new view for generating and displaying the QR code.

1. Create a view file at resources/views/qrcode.blade.php:

2. Create a route to display the form in routes/web.php:

Step 8: Testing the QR Code Display

Visit http://localhost:8000/qr-code in your browser. Enter some data into the form and submit it to generate and display the QR code.
