我正在尝试在Laravel 5.2中发送电子邮件。 它给我的错误是“ Mailer.php第410行中的InvalidArgumentException：回调无效。”

Question

I have provided host ,username ,password,port no. in .env and config/mail.php. I am sending email from localhost.

   public function sendEmail(){
          $data = array('name'=>"Swati Jadhav");
           $arrCategory=Category::getCategory();
          Mail::send('frontend.welcome',['arrCategory'=>$arrCategory] ,$data, function($message) {
                 $message->from('sender@gmail.com', 'text');
              $message->to('receiver@gmail.com', 'text')->subject('Welcome!');

          });

       }

Answer 1

Mail::send needs the callback as the 3rd parameter (not 4th). If you need to combine two parameter arrays you can do:

 Mail::send('frontend.welcome',array_merge(['arrCategory'=>$arrCategory] ,$data), function($message) {
             $message->from('sender@gmail.com', 'text');
          $message->to('receiver@gmail.com', 'text')->subject('Welcome!');

  });
