laravel如何验证是否等于变量

Question

在 laravel 验证（注册）中，我想将其中一个字段与 php 变量进行比较（它应该与那个相同）

我该怎么做？

protected function validator(array $data)
{

    return Validator::make($data, [
        'name' => 'required|max:255',
        'phone' => 'required|min:10|max:11|unique:users',
        'email' => 'required|email|max:255',
        'password' => 'required',
        'password_confirmation' => 'required',
        'user_captcha' => 'required'
    ]);
}

Answer 1

例如，您可以对这样的名称字段执行此操作：

$variable = "something"
return Validator::make($data, [
    'name' => [
        'required',
        Rule::in([$variable]),
    ],
    'phone' => 'required|min:10|max:11|unique:users',
    'email' => 'required|email|max:255',
    'password' => 'required',
    'password_confirmation' => 'required',
    'user_captcha' => 'required'
]);

记得导入规则类（使用 Illuminate\Validation\Rule;）

根据@patricus 的建议，您还可以连接变量

$variable = "something"
return Validator::make($data, [
    'name' => 'required|in:'.$variable,
    'phone' => 'required|min:10|max:11|unique:users',
    'email' => 'required|email|max:255',
    'password' => 'required',
    'password_confirmation' => 'required',
    'user_captcha' => 'required'
]);

EDIT2

如果你有一个数组变量：

$variable = ['one','two'];
return Validator::make($data, [
    'name' => 'required|in:'.implode(",", $variable),
    'phone' => 'required|min:10|max:11|unique:users',
    'email' => 'required|email|max:255',
    'password' => 'required',
    'password_confirmation' => 'required',
    'user_captcha' => 'required'
]);

或者

$variable = ['one','two']
return Validator::make($data, [
    'name' => [
        'required',
        Rule::in($variable),
    ],
    'phone' => 'required|min:10|max:11|unique:users',
    'email' => 'required|email|max:255',
    'password' => 'required',
    'password_confirmation' => 'required',
    'user_captcha' => 'required'
]);
