This is a barcode management package for Laravel that you can use in your projects.

Install via composer

composer require jobmetric/laravel-barcode

Documentation

Undergoing continuous enhancements, this package evolves each day, integrating an array of diverse features. It stands as an indispensable asset for enthusiasts of Laravel, offering a seamless way to harmonize their projects with barcode database models.

In this package, you can employ it seamlessly with any model requiring database barcode.

Now, let's delve into the core functionality.

Before doing anything, you must migrate after installing the package by composer.

php artisan migrate

Meet the HasBarcode class, meticulously designed for integration into your model. This class automates essential tasks, ensuring a streamlined process for:

In the first step, you need to connect this class to your main model.

use JobMetric\Barcode\HasBarcode;

class Product extends Model
{
    use HasBarcode;
}

How is it used?

Storing a barcode

You can now use the HasBarcode class to store barcodes for your model. The following example shows how to create a new product by saving a barcode:

$product = new Product();
$product->name = 'Product 1';
$product->save();

$product->storeBarcode('ean13', '1234567890123');

In this example, we created a new product and saved it to the database. Then, we stored a barcode for the product using the storeBarcode method. The first parameter is the barcode type, and the second parameter is the barcode value.

Retrieving a barcode

You can retrieve a barcode for a model using the getBarcode method. The following example shows how to retrieve a barcode for a product:

$product = Product::find(1);
$barcode = $product->getBarcode('ean13');

In this example, we retrieved a product from the database and then retrieved the barcode for the product using the getBarcode method. The parameter is the barcode type.

Deleting a barcode

You can delete a barcode for a model using the deleteBarcode method. The following example shows how to delete a barcode for a product:

$product = Product::find(1);
$product->forgetBarcode('ean13');

In this example, we retrieved a product from the database and then deleted the barcode for the product using the forgetBarcode method. The parameter is the barcode type.

Delete all barcodes

You can delete all barcodes for a model using the deleteAllBarcodes method. The following example shows how to delete all barcodes for a product:

$product = Product::find(1);
$product->forgetAllBarcodes();

In this example, we retrieved a product from the database and then deleted all barcodes for the product using the forgetAllBarcodes method.

Checking if a barcode exists

You can check if a barcode exists for a model using the hasBarcode method. The following example shows how to check if a barcode exists for a product:

$product = Product::find(1);
$exists = $product->hasBarcode('ean13');

In this example, we retrieved a product from the database and then checked if a barcode exists for the product using the hasBarcode method. The parameter is the barcode type.

Updating a barcode

You can update a barcode for a model using the storeBarcode method. The following example shows how to update a barcode for a product:

$product = Product::find(1);
$product->storeBarcode('ean13', '1234567890124');

In this example, we retrieved a product from the database and then updated the barcode for the product using the storeBarcode method. The first parameter is the barcode type, and the second parameter is the new barcode value.

Add barcodeable attribute in Resource

In the barcode resource, there is a field called bacodeable that can display your model, but it must be set as follows.

First, you create a listener for the model you want to display in the barcode resource.

php artisan make:listener AddProductResourceToBarcodableResourceListener

Then, you add the following code to the listener.

use JobMetric\Barcode\Events\BarcodeableResourceEvent;

class AddProductResourceToBarcodableResourceListener
{
    public function handle(BarcodeableResourceEvent $event)
    {
        $barcodeable = $event->barcodeable;

        if ($barcodeable instanceof \App\Models\Product) {
            $event->resource = new \App\Http\Resources\ProductResource($barcodeable);
        }
    }
}

Finally, you add the listener to the EventServiceProvider class.

protected $listen = [
    \JobMetric\Barcode\Events\BarcodeableResourceEvent::class => [
        \App\Listeners\AddProductResourceToBarcodableResourceListener::class,
    ],
];

The work is done, now when the BarcodeResource is called and if the ProductResource should be returned, the details of that resource will be displayed in the barcodeable attribute.
