Laravel in_array验证规则

Question

我已经定义了一个数组

$this->allslots=array('10:00:00', '10:10:00', '10:20:00', '10:30:00', '10:40:00', '10:50:00', '11:00:00', '11:10:00', '11:20:00', '11:30:00', '11:40:00', '11:50:00', '12:00:00', '12:10:00', '12:20:00', '12:30:00', '12:40:00', '12:50:00', '13:00:00', '13:10:00', '13:20:00', '13:30:00', '13:40:00', '13:50:00', '14:00:00', '14:10:00', '14:20:00', '14:30:00', '14:40:00', '14:50:00', '15:00:00', '15:10:00', '15:20:00', '15:30:00', '15:40:00', '15:50:00', '16:00:00', '16:10:00', '16:20:00', '16:30:00', '16:40:00', '16:50:00');

现在，在将数据保存到数据库之前，我要验证给定的输入是否与上述数组的某个值匹配。为此，我正在做这件事

$this->validate($request, [

        'field' => 'required|in_array:$this->allslots',
    ]);

但是，这会为每个输入返回验证错误。那么，我该怎么做呢？

Answer 1

试试这个：

'field' => 'required|in:' . implode(',', $this->allslots),

Answer 2

这比公认的答案更具语义性：

use Illuminate\Validation\Rule;

$this->allslots=array('10:00:00', '10:10:00', '10:20:00', '10:30:00', '10:40:00', '10:50:00', '11:00:00', '11:10:00', '11:20:00', '11:30:00', '11:40:00', '11:50:00', '12:00:00', '12:10:00', '12:20:00', '12:30:00', '12:40:00', '12:50:00', '13:00:00', '13:10:00', '13:20:00', '13:30:00', '13:40:00', '13:50:00', '14:00:00', '14:10:00', '14:20:00', '14:30:00', '14:40:00', '14:50:00', '15:00:00', '15:10:00', '15:20:00', '15:30:00', '15:40:00', '15:50:00', '16:00:00', '16:10:00', '16:20:00', '16:30:00', '16:40:00', '16:50:00');

$request->validate([
    'field' => [
        'required',
        Rule::in($this->allslots)
    ]
]);

Answer 3

我找到了一个更好的解决方案。验证in_array期望数组是请求中的参数之一。如果数组中有逗号，则接受的答案将不起作用。要在不创建新规则的情况下使用in_array，只需执行以下操作：

$this->allslots=array('10:00:00', '10:10:00', '10:20:00', '10:30:00', '10:40:00', '10:50:00', '11:00:00', '11:10:00', '11:20:00', '11:30:00', '11:40:00', '11:50:00', '12:00:00', '12:10:00', '12:20:00', '12:30:00', '12:40:00', '12:50:00', '13:00:00', '13:10:00', '13:20:00', '13:30:00', '13:40:00', '13:50:00', '14:00:00', '14:10:00', '14:20:00', '14:30:00', '14:40:00', '14:50:00', '15:00:00', '15:10:00', '15:20:00', '15:30:00', '15:40:00', '15:50:00', '16:00:00', '16:10:00', '16:20:00', '16:30:00', '16:40:00', '16:50:00');

$request['allslots'] = $this->allslots;

validate($request, [

        'field' => 'required|in_array:allslots.*',
    ]);

确保在末尾包含.*
