You need to write custom Validator, which will take the array and validate each ofthe emails in array manually. In Laravel 5 Request you can do something like that

您需要编写自定义验证器，它将获取数组并手动验证数组中的每个电子邮件。在 Laravel 5 Request 你可以做这样的事情

public function __construct() {
    Validator::extend("emails", function($attribute, $value, $parameters) {
        $rules = [
            'email' => 'required|email',
        ];
        foreach ($value as $email) {
            $data = [
                'email' => $email
            ];
            $validator = Validator::make($data, $rules);
            if ($validator->fails()) {
                return false;
            }
        }
        return true;
    });
}

public function rules() {
    return [
        'email' => 'required|emails'
    ];
}

In 5.6 or above you can define your validator rule as follows:

在 5.6 或更高版本中，您可以按如下方式定义验证器规则：

'email.*' => 'required|email'

'email.*' => 'required|email'

This will expect the emailkey to be an array of valid email addresses.

这将期望email密钥是一组有效的电子邮件地址。

We can achieve this without custom validation,We can overridden a method prepareForValidation

我们可以在没有自定义验证的情况下实现这一点，我们可以覆盖一个方法 prepareForValidation

protected function prepareForValidation() 
{
   //Here email we are reciving as comma seperated so we make it array
   $this->merge(['email' => explode(',', rtrim($this->email, ','))]);
}

Then above function will call automatically and convert email-ids to array, after that use array validation rule

然后上面的函数会自动调用并将 email-ids 转换为数组，然后使用数组验证规则

public function rules()
 {
     return [
        'email.*' => 'required|email'
     ];
 }

I did it like this. Working good for me. if email or emails ([email protected], [email protected], [email protected]) are coming from a Form like this following custom validator works. This need to be added to - AppServiceProvider.php - file. And new rule is - 'emails'.

我是这样做的。对我来说有效很好。如果电子邮件或电子邮件（[email protected]、[email protected]、[email protected]）来自以下自定义验证器工作的表单。这需要添加到 - AppServiceProvider.php - 文件中。新规则是-“电子邮件”。

    /**
     * emails
     * Note: this validates multiple emails in coma separated string.
     */
    Validator::extend('emails', function ($attribute, $value, $parameters, $validator) {
        $emails = explode(",", $value);
        foreach ($emails as $k => $v) {
            if (isset($v) && $v !== "") {
                $temp_email = trim($v);
                if (!filter_var($temp_email, FILTER_VALIDATE_EMAIL)) {
                    return false;
                }
            }
        }
        return true;
    }, 'Error message - email is not in right format');

And in your controller, it can be used like this:

在您的控制器中，它可以这样使用：

    $this->validate($request, [
        'email_txt_area' => 'emails',
    ]);

Laravel 5.2 introduced array validation and you can easily validate array of emails :)

Laravel 5.2 引入了数组验证，您可以轻松验证电子邮件数组 :)

All you need is exploding the string to array.

您所需要的只是将字符串分解为数组。
