如果回傳，我如何才能添加alpha_num到驗證中？$this->language()en
public function rules()
{
return [
'title' => ['required', 'alpha_num'],
];
}
public function language()
{
// For brevity I only return "en", it could be other languages
return 'en';
}
uj5u.com熱心網友回復：
use Illuminate\Validation\Rule;
public function rules()
{
return [
'title' => ['required', Rule::when($this->language() === 'en', ['alpha_num'])],
];
}
