laravel - 如何允许 Laravel 数字验证为空值

Question

如何设置Laravel5.2不需要数字验证？我刚刚使用了此代码，但是当我不发送值或选择框未选择项目时，我出现错误，val 字段大多数是数字...我需要如果请求没有床输入，则不要理会床。下床验证...

$this->validate($request, [
        'provinces_id' => 'required|numeric',
        'type' => 'required',
        'bed' => 'numeric',
]);

Answer 1

如果我没理解错的话，您正在寻找 sometimes规则:

'bed' => 'sometimes|numeric',

In some situations, you may wish to run validation checks against a field only if that field is present in the input array. To quickly accomplish this, add the sometimes rule to your rule list
