How to generate bar code in laravel
Generating a barcode in Laravel can be achieved by using a barcode library like "Picqer/php-barcode-generator".
Follow below steps to generate a barcode in Laravel:
Step 1- Install the library via Composer by run below command in your terminal:
composer require picqer/php-barcode-generator
Step 2- Create a controller and add the following code to generate a barcode:
use Picqer\Barcode\BarcodeGeneratorPNG;
class BarcodeController extends Controller
{
public function generateBarcode($code)
{
$generator = new BarcodeGeneratorPNG();
header('Content-Type: image/png');
echo $generator->getBarcode($code, $generator::TYPE_CODE_128);
}
}
In this code, we are using the BarcodeGeneratorPNG class from the Picqer\Barcode namespace to generate the barcode. We then set the content type to image/png and output the generated barcode.
Step 3- Create a route in web.php to call the controller method:
Route::get('/barcode/{code}', 'BarcodeController@generateBarcode');
This will allow us to call the generateBarcode method by passing a code parameter to the URL like http://localhost/barcode/123456.
Step 4 - Call the URL in the browser to see the generated barcode.
Note: You may need to adjust the namespace and use statements based on your application's folder structure.
That's it! You now have a basic implementation of generating a barcode in Laravel.
