Laravel 5.5带OR/ELSE条件的验证

我假设您使用表单请求验证,因此可以执行以下操作:

$rules = [
   'type' => 'required',
   'field' =>  ['required'];
];

$rules['field'][] = ($this->input('type') == 1) ? 'size:11' : 'size:14';

return $rules;

使用Laravel验证器, 参考链接: https://laravel.com/docs/5.5/validation

 $validatedData = $request->validate([
            'title' => 'required|unique:posts|max:255',
            'body' => 'required',
        ]);
