required_if驗證規則與陣列驗證規則不起作用|拉拉維爾|驗證

我有以下驗證規則，我需要確保streaming_platforms陣列包含正確的資訊。因此，如果鍵為真，則stream_key和stream_url是必需的enable。本stream_key應該是一個字串stream_url應該是一個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值為 false ，stream_url 和 stream_key 各自的 URL 和字串驗證規則也會觸發。那么，如果required_if沒有應用，為什么不停止檢查下一個規則呢？

所以我嘗試使用以下資料。

{
    "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}
    ]
}

所以它回傳

stream_platforms.1.stream_url 格式無效。對于 Facebook 行。

我在某處讀到您可以使用sometimes規則執行以下操作，即。但我不知道如何處理陣列型別的資料。

$validator = Validator::make($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;
});

影像形式的真實用例。

uj5u.com熱心網友回復：

使用exclude_if規則有條件地從驗證中排除該欄位。

$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

請注意，這也會阻止使用該Illuminate\Validation\Validator::validated()方法輸出資料：

dump($v->validated());

輸出：

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