php - 在 Laravel 验证期间获取列表的索引并显示在错误消息中

Question

我有一个验证规则如下。我正在通过 ValidateRequests 特性使用 validate 方法。

$this->validate($request, [
    'entries'                 => 'required|max:5',
    'entries.*.name'          => 'required',
    'entries.*.email'         => 'required|email',
    'entries.*.mobile_number' => 'required'
]);

这些是我遇到的一些示例错误消息。

[
    'entries.0.name'  => ['The entries.0.name is required.'],
    'entries.1.email' => ['The entries.1.email must be a valid email address.']
]

在修改此类消息时，是否可以仅使用 validation.php 将消息修改为这些消息？

[
    'entries.0.name'  => ['Line 0 - The name is required.'],
    'entries.1.email' => ['Line 1 - The email must be a valid email address.']
]

如果你想自定义错误信息，那么你可以这样做:

$validator = Validator::make($request->all(), [
                        'entries'                 => 'required|max:5',
                        'entries.*.name'          => 'required',
                        'entries.*.email'         => 'required|email',
                        'entries.*.mobile_number' => 'required'
                    ]);

$validator->setAttributeNames([
            'entries.*.name'          => 'name',
            'entries.*.email'         => 'email',
            'entries.*.mobile_number' => 'mobile number'
        ]);

$errors = $validation->errors()->all();
foreach ($errors as $key => $error) {
    $errors[$key] = "Line {$key} - $error";
}

// dd($errors);

if($validation->fails()) {
    return redirect()->back()->withErrors($errors());
}
