required_if 带有数组验证规则的验证规则不起作用 |拉拉维尔 |验证

Question

我有以下验证规则，我需要确保streaming_platforms 数组包含正确的信息。因此，如果 enable 键为真，则需要 stream_key 和 stream_url。 stream_key 应该是一个字符串，stream_url 应该是一个 URL。

$validator = Validator::make($input, [
    'name' => 'required|string|min:3|max:255',
    'type' => 'required|in:private,public',
    'streaming_platforms.*.stream_url' => 'required_if:streaming_platforms.*.enable,true|url',
    'streaming_platforms.*.stream_key' => 'required_if:streaming_platforms.*.enable,true|string',
], [
    'streaming_platforms.*.stream_url.required_if' => 'The stream url field is required when platform is enable.',
    'streaming_platforms.*.stream_key.required_if' => 'The stream key field is required when platform is enable.',
]);

if ($validator->fails()) {
    return $this->failResponse([
        "message" => $validator->errors()->first(),
        "messages" => $validator->errors(),
    ], 422);
}

一切正常，但即使 enable 值为 false，stream_url 和 stream_key 的 URL 和字符串验证规则也会触发。那么，如果没有应用required_if，为什么不停止检查下一个规则呢？

所以我尝试了以下数据。

{
    "name":"testing",
    "type":"public",
    "streaming_platforms":[
        {"id":16,"platform":"youtube","enable":true,"stream_url":"https://www.google.com","stream_key":"abdefghijk"},
        {"id":17,"platform":"facebook","enable":false,"stream_url":null,"stream_key":null},
        {"id":18,"platform":"custom","enable":false,"stream_url":null,"stream_key":null}
    ]
}

所以它返回

streaming_platforms.1.stream_url 格式无效。为了 Facebook 行。

我在某处读到您可以执行以下操作，即使用sometimes 规则。但我不知道如何处理数组类型的数据。

$validator = Validator::make($request->all(), [
    'name' => ['required', 'min:3', 'max:255'],
    'is_public_template' => 'boolean',

    'logo' => ['required_if:is_public_template,true'],
]);
$validator->sometimes('logo', 'required|image|mimes:jpeg,bmp,png,jpg|dimensions:min_width=128,min_height=128', function ($input) {
    return $input->is_public_template;
});

图片形式的真实用例。

使用exclude_if 规则conditionally exclude 验证字段。

$data = [
    "name" => "testing",
    "type" => "public",
    "streaming_platforms" => [
        ["id" => 16, "platform" => "youtube", "enable" => true, "stream_url" => "https://www.google.com", "stream_key" => "abdefghijk"],
        ["id" => 17, "platform" => "facebook", "enable" => false, "stream_url" => null, "stream_key" => null],
        ["id" => 18, "platform" => "custom", "enable" => false, "stream_url" => null, "stream_key" => null],
     ]
];

$rules = [
    'name' => 'required|string|min:3|max:255',
    'type' => 'required|in:private,public',
    'streaming_platforms.*.stream_url' => 'exclude_if:streaming_platforms.*.enable,false|required|url',
    'streaming_platforms.*.stream_key' => 'exclude_if:streaming_platforms.*.enable,false|required|string',
];

$messages = [
    'streaming_platforms.*.stream_url.required' => 'The stream url field is required when platform is enable.',
    'streaming_platforms.*.stream_key.required' => 'The stream key field is required when platform is enable.',
];

$v = Illuminate\Support\Facades\Validator::make($data, $rules, $messages);

dump($v->fails());

// false

注意，这也会阻止使用Illuminate\Validation\Validator::validated() 方法输出数据：

dump($v->validated());

输出：

   [
     "name" => "testing",
     "type" => "public",
     "streaming_platforms" => [
       [
         "stream_url" => "https://www.google.com",
         "stream_key" => "abdefghijk",
       ],
     ],
   ]
