我有一个表单，当我填写并提交时，它会向多个收件人发送电子邮件，当我这样做时，我会收到这个错误htmlspecialchar((需要参数1是字符串，给定数组(View:C:\wamp64\www\star\resources\views\email_invite_template.blade.php下面是我的代码：

表单

<input name="iname[]" class="form-control" type="text" placeholder="Name" > 
<input name="iemail[]" class="form-control" type="text" placeholder="Email" >
<input type="submit" value="Send Invite" >

发送电子邮件

class SendEmail extends Mailable
{
use Queueable, SerializesModels;

public $data;

public function __construct($data)
{
$this->data = $data;

}
}

控制器

public function storeInvite(Request $request)
{
$eventid = $request->get('eventid');
$iname = $request->get('iname');
$iemail = $request->get('iemail');
$data = array(
'dname'      =>  $request->iname,
'demail'   =>   $request->iemail

<p></b>{{ $data['demail'] }}</b></p>

Thanks,<br>
{{ config('app.name') }}
@endcomponent

不能在每次迭代中都向前传递$data。您需要构建自己的数组，其中包含每个name和email对：

$data = [
'dname' => $request->iname,
'demail' => $request->iemail
];
// dname: `[0 => 'Mike', 1 => 'Bob', ...]
// demail: `[0 => '[e-mail]', 1 => '[e-mail]', ...]
foreach($data['demail'] as $index => $email){
Mail::to($email)->send(new SendEmail([
'dname' => $data['dname'][$index],
'demail' => $email
]));
}

现在，您发送一个包含2个元素的数组，dname和demail，每个元素代表一对数组元素：

// 1st Iteration: ['dname' => 'Mike', 'demail' => '[e-mail]']
// 2nd Iteration: ['dname' => 'Bob', 'demail' => '[e-mail]']

这100%取决于您在输入中输入相同数量的dname和demail值。如果你有3封电子邮件，但只有2个名字，这是行不通的。
