How to Generate BarCode in Laravel?

Published on : April 26,2023

Generating barcodes in Laravel is a common requirement for many web applications, especially those that deal with product inventory and sales. Barcodes provide a quick and efficient way to identify products, track inventory, and process transactions. In this blog post, we'll explore how to generate barcodes in Laravel using the SimpleSoftwareIO/simple-qrcode package.

Step 1: Install the Simple-QRCode Package

The first step in generating barcodes in Laravel is to install the Simple-QRCode package. Simple-QRCode is a PHP library that provides an easy way to generate QR codes and barcodes. To install the package, open your terminal and navigate to your Laravel project directory, then run the following command:

composer require simplesoftwareio/simple-qrcode

This will install the package and its dependencies.

Step 2: Generate Barcodes

Once the package is installed, you can use it to generate barcodes in Laravel. To generate a barcode, you need to first import the QrCode facade. Open the controller where you want to generate the barcode and add the following code:

use SimpleSoftwareIO\QrCode\Facades\QrCode;

public function generateBarcode()
{
    $barcode = QrCode::size(500)->generate('My first barcode!');
    return view('barcode', ['barcode' => $barcode]);
}

In the code above, we're using the QrCode facade to generate a barcode with a size of 500 pixels and the text 'My first barcode!'. We're then passing the barcode to the 'barcode' view.

The size() method sets the size of the barcode in pixels. You can adjust this value to suit your requirements. The generate() method takes a string as input and generates a barcode from it.

Step 3: Display the Barcode

Finally, we need to display the barcode in our view. Create a new blade view called 'barcode.blade.php' and add the following code:

<img src="data:image/png;base64, {!! base64_encode($barcode) !!} ">

This will display the barcode image in the browser.

The base64_encode() function converts the binary barcode data into a base64-encoded string, which can be embedded in an image tag.

Customizing the Barcode

You can customize the barcode by changing the text, size, color, and other properties. For example, to change the text of the barcode, modify the string passed to the generate() method. To change the size of the barcode, modify the value passed to the size() method. To change the color of the barcode, use the color() method.

$barcode = QrCode::size(500)
                ->backgroundColor(255, 255, 204)
                ->color(0, 0, 0)
                ->generate('My customized barcode!');

In the code above, we're setting the background color to a light yellow, the foreground color to black, and the text to 'My customized barcode!'.

You can also add logos or images to the barcode using the merge() method. The merge() method takes an image file path as input and merges it with the barcode. For example:

$barcode = QrCode::size(500)
                ->merge('path/to/logo.png', 0.5, true)
                ->generate('My barcode with logo!');

In the code above, we're merging the barcode with an image file located at 'path/to/logo.png'. The second parameter of the merge() method specifies the opacity of the logo (0.0 to 1.0), and the third parameter specifies whether to resize the logo to fit the barcode.
