]; and this is my loginMail.php:

<?php

namespace App\Mail;

    use Illuminate\Bus\Queueable;

    use Illuminate\Queue\SerializesModels;

    *
    * @return $this
    */
public function build()
{
    return $this->markdown('emails.login')->with('password','role');
}
 }

and this is login.blade.php:

and this is my controller function:

public function store(Request $request)
     {
      //

            'tel' => 'required|number',
            'role' => 'required'

return User::create([
        'name' => $request->name,
        'email'=> $request->email,
        'password'=> bcrypt($request->password),

]);
Mail::to($request->email)->send(new loginMail($request->password,$request->role));
