使用电子邮件类联系表单

I am so new at codeigniter. But I am working on a contact form. I want that let visitor fulfill the form (input name,email and message) then when they send the message must come into my inbox.

This is my controller:

public function ilet(){
        $name    = $this->input->post("name");
        $email   = $this->input->post("email");
        $message = $this->input->post("message");

        $config = array(
            "protocol"    => "smtp",
            "smtp_host"   => "ssl://smtp.gmail.com",
            "smtp_port"   =>"465",
            "smtp_user"   =>$email,
            "starttls"    =>true,
            "charset"     =>"utf-8",
            "mailtype"    =>"html",
            "wordwrap"    => true,
            "newline"     =>"
",
        );

        $this->load->library("email", $config);

         $this->mail->from($email);
         $this->email->to("cugurel7@gmail.com");
         $this->email->subject("Müşteri bilgi mesajı");
         $this->email->message($message);

         $send = $this->email->send();

         if($send)
         {
             echo "Mail gönderme işlemi başarılı";
         }
         else {
             echo "Başarısız";
         }


    }

this is my view:

<form id="contact-form" action="/yansayfa/ilet" method="POST" >
                <div class="row">
                    <div class="col-md-6">
                        <div class="form-group" ">
                            <label for="form_name">Adınız Soyadınız</label>
                            <input  style="border-radius: 0px;" id="name" type="text" name="name" class="form-control"
                                   placeholder="İsim & Soyisim" 
                                   >
                        </div>
                    </div>
                    <div class="col-md-6">
