Custom casts

You can create custom casts to have Laravel automatically format your Eloquent model data. Here's an example that capitalises a user's name when it is retrieved or changed.

 1class CapitalizeWordsCast implements CastsAttributes
 2{
 3    public function get($model, string $key, $value, array $attributes)
 4    {
 5        return ucwords($value);
 6    }
 7 
 8    public function set($model, string $key, $value, array $attributes)
 9    {
10        return ucwords($value);
11    }
12}
13 
14class User extends Model
15{
16    protected $casts = [
17        'name'  => CapitalizeWordsCast::class,
18        'email' => 'string',
19    ];
20}
