Laravel password validation fail on "min length" if empty
提问by kuchar
My validator rule looks like this:
我的验证器规则如下所示：
$validator = Validator::make($request->all(), [
'name' => 'required|min:5|max:255',
'email' => [
'required',
'max:255',
'email',
Rule::unique('users')->ignore($id),
],
'password' => 'min:6|confirmed',
], [
'confirmed' => 'Has?o musi si? zgadza?',
'unique' => 'Wpisz inny adres email, ten adres jest zaj?ty',
'required' => 'To pole jest wymagane.',
'min' => 'To pole musi mie? minimum :min znaków.',
]);
if ($validator->fails()) {
return redirect('/panel/users/'.$id.'/edit')
->withErrors($validator)
->withInput();
}
When i edit user without change password, validator fails with 'min' rule. As you can see my validator doesnt require password, so why it validating?
当我在不更改密码的情况下编辑用户时，验证器因“最小”规则而失败。正如您所看到的，我的验证器不需要密码，那么为什么要验证呢？

It's look like what you want.
它看起来像你想要的。
$validator->sometimes('password', 'min:6|confirmed', function ($input) {
return (strlen($input->password) > 0);
});

use nullable rule
使用可为空规则
'nullable|min:6|confirmed'
回答by Ian
You are coming across expected behaviour.
您遇到了预期的行为。
min:value
最小值：值
The field under validation must have a minimum value. Strings, numerics, and files are evaluated in the same fashion as the size rule.
验证中的字段必须具有最小值。字符串、数字和文件的计算方式与大小规则相同。
as per the docs.
根据文档。
You can use the sometimesrule
你可以使用sometimes规则
Validator::make($request->all(), [
'password' => 'sometimes|min:6|confirmed',
]
回答by Alex Harris
You can use sometimesfor this case:
您可以sometimes在这种情况下使用：
$this->validate($request, [
'password' => 'sometimes|min:6',
]);
You can read more about sometimeshere:
您可以sometimes在此处阅读更多信息：
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:
在某些情况下，您可能希望仅当输入数组中存在该字段时才对该字段运行验证检查。要快速完成此操作，请将有时规则添加到您的规则列表中：
confirmedseems as if it can also cause a problem. So try doing it manually:
confirmed似乎它也会引起问题。因此，请尝试手动执行此操作：
'password' => 'required|min:6',
'password_confirmation' => 'required|min:6|same:password',
