Using Eloquent Accessors and Mutators for Data Transformation
Transform model attributes automatically when retrieving or setting them using Laravel Eloquent accessors and mutators, perfect for formatting or encryption.
use Illuminate\Database\Eloquent\Casts\Attribute;
use Illuminate\Database\Eloquent\Model;
class User extends Model
{
/**
* Get the user's first name.
* For Laravel 9+ using new Attribute casting.
*/
protected function firstName(): Attribute
{
return Attribute::make(
get: fn (string $value) => ucfirst($value),
set: fn (string $value) => strtolower($value),
);
}
/**
* Old style accessor for Laravel < 9.
* public function getFullNameAttribute()
* {
* return "{$this->first_name} {$this->last_name}";
* }
*/
}
How it works: This snippet demonstrates how to use Eloquent Accessors and Mutators for automatic data transformation. Using the new `Attribute::make()` syntax (Laravel 9+), the `get` closure defines an accessor that capitalizes the first letter of the `first_name` attribute whenever it's retrieved. The `set` closure defines a mutator that converts the `first_name` to lowercase before it's saved to the database. This allows for consistent data formatting directly within the model.
