Question

我有两个复选框字段tech和active，我想成为nullable，但我也希望可以将输入的值限制为一个字段的单个值，并且另一个字段的两个值之一。

我遇到了答案stackoverflow，但我似乎没有正确实现它。这是我的代码：

 $validator = Validator::make($request->all(), [
    'name' => 'required|string|max:150',
    'email' => 'required|string|max:200',
    'phone' => 'required|digits:11',
    'branch' => 'required|string',
    'department' => 'required|string',
    'tech' => ['nullable','digits:1', Rule::in([1, 2])],
    'role' => 'required|string',
    'active' => ['nullable', 'string', 'max:6', Rule::in(['active'])]
 ]);

如果我这样做：

'tech' => 'nullable|digits:1',
'active' => 'nullable|string|max:6'

它可以工作，但是我需要验证这些字段可以允许的值。

Chin Leung通过注释部分的实现为我解决了这个问题。

$validator = Validator::make($request->all(), [
   'name' => 'required|string|max:150',
   'email' => 'required|string|max:200',
   'phone' => 'required|digits:11',
   'branch' => 'required|string',
   'department' => 'required|string',
   'tech' => 'nullable|digits:1|in:1,2',
   'role' => 'required|string',
   'activate' => 'nullable|string|max:6|in:active'
]);

您甚至可以在验证器类中将闭包传递给验证器。

$validator = Validator::make($request->all(), [
    'name' => 'required|string|max:150',
    'email' => 'required|string|max:200',
    'phone' => 'required|digits:11',
    'branch' => 'required|string',
    'department' => 'required|string',
    'tech' => function($attribute, $value, $fail){
        if (isset($value)) {
            sizeof($value) > 1 ?? return $fail($attribute." is invalid");
            in_array($value, [1,2]) ?? return $fail($attribute." is invalid");
        }
    },
    'role' => 'required|string',
    'active' => ['nullable', 'string', 'max:6', Rule::in(['active'])]
 ]);

Laravel-验证字段输入应为一组给定值之一的可空字段
