数组验证

验证数组表单输入字段非常简单。

假设你必须验证给定数组中的每个名称，电子邮件和父名称。你可以执行以下操作：

$validator = \Validator::make($request->all(), [
    'name.*'       => 'required', 
    'email.*'      => 'email|unique:users',
    'fatherName.*' => 'required'
]);

if ($validator->fails()) {
    return back()->withInput()->withErrors($validator->errors());
}

Laravel 显示验证的默认消息。但是，如果要为基于阵列的字段定制消息，可以添加以下代码：

[
    'name.*' => [
        'required' => 'Name field is required',
    ],
    'email.*' => [
        'unique'   => 'Unique Email is required',
    ],
    'fatherName.*' => [
        'required' => 'Father Name required',
    ]
]

你的最终代码如下所示：

$validator = \Validator::make($request->all(), [
    'name.*'       => 'required', 
    'email.*'      => 'email|unique:users',
    'fatherName.*' => 'required',
], [
    'name.*'       => 'Name Required',
    'email.*'      => 'Unique Email is required',
    'fatherName.*' => 'Father Name required',
]);

if ($validator->fails()) {
    return back()->withInput()->withErrors($validator->errors());
}
