Generate unique SKUs when saving any Eloquent model.
$model = new EloquentModel();
$model->name = 'Laravel is Awesome';
$model->save();
echo $model->sku; // ouputs "LAR-80564492"Package will add a new method to Laravel's Illuminate\Support\Str::sku() class to generate an SKU for you.
You can install the package via composer:
composer require binary-cats/laravel-skuThe service provider will automatically register itself.
You can publish the config file with:
php artisan vendor:publish --provider="BinaryCats\Sku\SkuServiceProvider" --tag="config"This is the contents of the config file that will be published at config/laravel-sku.php:
return [
/*
|--------------------------------------------------------------------------
| SKU settings
|--------------------------------------------------------------------------
|
| Set up your SKU
|
*/
'default' => [
/*
* SKU is based on a specific field of a model
* You can use a single field or an array of fields
*/
'source' => 'name',
/*
* Destination model field name
*
*/
'field' => 'sku',
/*
* SKU separator
*
*/
'separator' => '-',
/*
* Shall SKUs be enforced to be unique
*
*/
'unique' => true,
/*
* Shall SKUs be generated on create
*
*/
'generate_on_create' => true,
/*
* Shall SKUs be re-generated on update
*
*/
'generate_on_update' => true,
],
/*
|--------------------------------------------------------------------------
| SKU Generator
|--------------------------------------------------------------------------
|
| Define your own generator if needed.
|
*/
'generator' => \BinaryCats\Sku\Concerns\SkuGenerator::class,
];Please note that the above set up expects you have an sku field in your model. If you plan to manually overwrite the values, please make sure to add this field to fillable array;
Add BinaryCats\Sku\HasSku trait to your model. That's it!
namespace App;
use BinaryCats\Sku\HasSku;
use Illuminate\Database\Eloquent\Model;
class Product extends Model
{
use HasSku;
}Behind the scenes this will register an observer for the sku field, which will be generated every time you save the model.
If you want to change settings for a specific model, you can overload the skuOptions() method:
namespace App;
use BinaryCats\Sku\HasSku;
use BinaryCats\Sku\Concerns\SkuOptions;
use Illuminate\Database\Eloquent\Model;
class Product extends Model
{
use HasSku;
/**
* Get the options for generating the Sku.
*
* @return BinaryCats\Sku\SkuOptions
*/
public function skuOptions() : SkuOptions
{
return SkuOptions::make()
->from(['label', 'another_field'])
->target('arbitrary_sku_field_name')
->using('_')
->forceUnique(false)
->generateOnCreate(true)
->refreshOnUpdate(false);
}
}Assuming you want some extra logic, like having a default value, or defining prefix for an SKU, you can implement your own SkuGenerator. It is easiest to extend the base class, but you are free to explore any which way.
First, create a custom class:
namespace App\Components\SkuGenerator;
use BinaryCats\Sku\Concerns\SkuGenerator;
class CustomSkuGenerator extends SkuGenerator
{
/**
* Get the source fields for the SKU.
*
* @return string
*/
protected function getSourceString(): string
{
// fetch the source fields
$source = $this->options->source;
// Fetch fields from model, skip empty
$fields = array_filter($this->model->only($source));
// Fetch fields from the model, if empty, use custom logic to resolve
if (empty($fields)) {
return 'some-random-value-logic';
}
// Impode with a separator
return implode($this->options->separator, $fields);
}
}and then update generator config value:
'generator' => \App\Components\SkuGenerator\CustomSkuGenerator::class,You can also opt out to change implemetation completely;
just remember that custom generator must implement BinaryCats\Sku\Contracts\SkuGenerator.
