使用 htmlspecialchars() 发送的多个收件人电子邮件需要参数错误

Question

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，当我这样做时我收到此错误 htmlspecialchars() expects parameter 1 to be string, array given （查看：C:\wamp64\www\star\resources\views\emails\email_invite_template.blade.php 下面是我的代码：

表格

<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" >

发送邮件

class SendEmail extends Mailable
{
    use Queueable, SerializesModels;
  
    public $data;
   
    public function __construct($data)
    {
        $this->data = $data;
    }
   
    public function build()
    {
        return $this->subject('Invitation to Mase')
        ->markdown('emails.email_invite_template')
        ->with('data', $this->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
    );

    foreach($data['demail'] as $user){
        Mail::to($user)->send(new SendEmail($data));
    }

    return redirect()->back()->with('status','Invitation sent to users');

}

电子邮件模板(email_invite_template.php)

    @component('mail::message')
    
    <p>Hi, {{ $data['dname'] }}</p>
    <p>You have just been invited to an event below is your invitation code:</p>
    <p></b>{{ $data['demail'] }}</b></p>
    
    Thanks,<br>
    {{ config('app.name') }}

@endcomponent

谢谢

您不能在每次迭代时都向前传递 $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 => 'mike@test.com', 1 => 'bob@test.com', ...]

foreach($data['demail'] as $index => $email){
  Mail::to($email)->send(new SendEmail([
    'dname' => $data['dname'][$index],
    'demail' => $email
  ]));
}

现在，您要发送一个包含 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' => 'mike@test.com']
// 2nd Iteration: ['dname' => 'Bob', 'demail' => 'bob@test.com']

这 100% 取决于您在输入中输入相同数量的 dname 和 demail 值。如果您有 3 个电子邮件地址，但只有 2 个姓名，这将不起作用。
